Importance of Vitamin D for Women

Dr. Sangeeta Malu, Dietitian/Nutritionist
Vitamin D is a vital nutrient required for all kinds of bodily functions. It is important especially for women who suffer from more deficiency diseases as compared to men. The major source of vitamin D is sunlight. Some fish like salmon and mackerel also have vitamin D. Any kind of deficiency disease needs to be avoided at all costs. A healthy lifestyle and a balanced diet are key factors in avoiding such health problems. How Does Vitamin D Affect Women? In women, Vitamin D helps prevent various health issues. Some are:Vitamin D increases fertility by at least 6%. Also it lowers progesterone and estradiol which often causes infertility. In pregnant women, it is beneficial for mother and also the child.It reduces chances of breast cancer as it lowers rate of cancerous cell growth in the breast. That is because it actively works in all cells of the body.Brittle bones and arthritis is a common problem in women. However adequate quantity of Vitamin D will improve bone strength. Vitamin D deficiency can drastically increase the chance of hip fractures in women. Most women with osteoporosis or other bone issues are found to be lacking in Vitamin D.Vitamin D provides support to certain killer cells in the immunity system of the body. Such killer cells destroy harmful pathogens.In pregnant women it can create many problems like gestational diabetes or even pre-eclampsia.In some women, deficiency of vitamin D may lead to irregular hormone production and hormones regulate all bodily functions.Vitamin D or "sunshine vitamin" as it's sometimes called, can help avoid or even cure many diseases. It can help avoid lifestyle diseases, polycystic ovarian syndrome and other problems. Scientific studies have shown the benefits of getting a daily dose of this essential Vitamin. Thus, the importance of vitamin D for women cannot be overruled.

Vitamin C and E Supplements Might Hamper Muscle Endurance

Ms. Swati Kapoor, Dietitian/Nutritionist
Both vitamin C and E supplements are widely popular and are used together by many who want to improve their health and performance. But a New Norwegian study indicates that the use of these antioxidants can counter the effect of exercise – at least if you are in training for events that require plenty of stamina, such as a marathon.Study conducted in Norwegian, by Dr. Paulson, a researcher at the Norwegian School of Sport Sciences (NIH) which shows that exercising increases muscle oxidant production, which participates in the signalling processes leading to muscle adaption. It is possible that high doses of vitamins C and E act as antioxidants and take away some of this oxidative stress, hence blocking muscular endurance development.Whilst the supplements did not affect maximal oxygen uptake but the results also showed that the production of new muscle mitochondria – found in cells and known as the power house of the cell, convert nutrients into the energy in muscle cells need to perform various functions. Their number gets increased only in the group without supplements.The high doses of the two vitamins, which are both antioxidants, remove some of the stress that muscles are subjected to before, during and after training.So the men and women with no intake of vitamin C and E supplement during training have more stamina because oxidative stress on their muscles increased the muscles adaptation.Researchers also said that the muscles’ natural ability to burn fat during endurance training is reduced due to intake of vitamin E and C supplements.Future studies are needed to determine the underlying mechanisms of these results, but researchers assume that the vitamins interfered with cellular signalling and blunted expression of certain genes.So, high dosages of vitamin C and E -- as commonly found in supplements -- should be used with caution, especially if you are undertaking endurance training.

Vitamin D - Essential Vitamin for Weight Loss

Ms. Swati Kapoor, Dietitian/Nutritionist
Do you also blame some food you ate for those extra pounds on your waist? But now new research have shown that the reason may be the food you are not eating. New study reported in the Archives of Internal Medicine reports that Vitamin D might be a key nutrient to help you lose weight.Widespread survey data is also indicating higher weight among groups of people with lower Vitamin D levels, that helps to regulate hormones that are effective for managing weight, thyroid, the body's natural fat burning ability and more. Vitamin D is an important nutrient required in the body for proper functioning of every cell. Special receptors for vitamin D signal whether you should burn fat or simply store it; when vitamin D plugs into these receptors, it's like a key that revs your body's flab-melting mechanism.Daily recommended requirement for Vitamin-D is 600 IU-700 IU till the age of 70 years. This can be obtained from exposure to sunlight for 10-15 minutes daily.Vitamin D deficiency has been shown to be a factor in the accumulation of excess body fat. In the absence of sufficient vitamin D the body increases the number and size of newly formed fat cells that promote and accelerate abdominal obesity. Also, Vitamin D in conjunction with calcium helps to properly assimilate food and regulate normal blood sugar levels. When there is a lack of calcium, often times due to a vitamin D deficiency, the body increases production of synthase, a fatty acid enzyme that coverts calories into fat. Calcium deficiency can cause increase in synthase production explaining the correlation between low levels of vitamin D and obesity.Vitamin D is also a pro-hormone that becomes activated in the kidneys to become a potent hormone that controls the growth of cells. In the absence of sufficient circulating levels of the active form, both adipocytes and cancer cells are allowed to multiply relatively unchecked.Sufficient levels of vitamin D signal fat cells to shrink. This makes weight loss much easier when calories are restricted and also might keep cancer cell growth in check. Regulating vitamin D intake can help your body burn abdominal fat and lose weight. Ensure you have enough of this critical nutrient circulating in your blood to promote good health and natural weight loss diet.Vitamin D SourcesThe main Vitamin D source is sunlight. Human skin has special precursor 7-dehydrocholesterol which converts UV sun rays to Vitamin D and supply approximately 90% of dietary requirement. But nowadays because of less exposure to sunlight and use of sunscreen inhibit the production of vitamin D in body. Sunscreen can inhibit the production of vitamin D by 90-99% depending upon SPF of the cream. Another reason for Vitamin D deficiency is air pollution which can trap some of the UVB rays, so less of them are able to reach your skin at any time of day.Apart from sunlight the main Vitamin D food sources are milk & dairy products, eggs (yolk), cod liver oil, salmon, tuna, mackerel. For those on dairy free, vegetarian diets might need to supplement with fish oil supplements. To increase your vitamin D intake include vitamin D rich food in your snack time. For example, you can include plain buttermilk with any fruit or small handful of nuts in between your meal.

Benefits of Vitamin C for Skin, Hair and Health

Ms. Anu Priya, Alternative Medicine
Vitamin C is the most familiar of all the nutrients because of its widespread use as a dietary supplement. Vitamin C is very critical for human beings, and all mammals can use their own cells to make Vitamin C. Vitamin C is needed for the growth and repair of tissues in our body and because the body does not store Vitamin C in its tissues, we need to consume it on a regular basis.Our body needs Vitamin C to make collagen – a protein that helps support tendons, ligaments and blood vessels and keeps the skin and other organs together. Vitamin C improves the absorption of iron from plant-based foods and helps strengthen our immunity system, thus protecting us from diseases.Vitamin C Foods And Sources: Citrus fruits, Chilies, Bell peppers, Amla, Kiwi, Berries, Papayas, Pineapple, Guava, Broccoli, Cauliflower, Cherries, Tomatoes, Apricots, Cabbage, Turnips, Peas, cloves, mango, spinach, potato, Herbs like thyme, parsley, basil, cilantro, green coriander and chives are also good sources of Vitamin C.Health Benefits Of Vitamin CVitamin C will benefit your health in a great way. Read below to know the amazing health benefits:Immunity: A healthy dose of Vitamin C protects our body from infections and maintains healthy bones and teeth. It also improves our body’s ability to repair wounds and keeps us immune from bacteria, viruses and infection. Not only is it a well-known component of our immune system, it is also necessary for collagen, the main structural protein found in connective tissue. Vitamin C, taken orally, helps wounds heal faster and better. Applied topically, it protects the skin from free radical damage from the exposure to UV rays.Common Cold: Vitamin C reduces the severity of cold symptoms and acts as an effective antihistamine that lessens the unpleasant effects of the common cold, including inflammation, runny nose and aches. It also controls the allergy that causes the cold. It reduces the histamine level and often shortens the duration of the cold.Antioxidant: Vitamin C is a powerful and effective antioxidant that protects our body from free radicals that cause oxidative stress, or ”cellular rust”, that can lead to a host of severe medical conditions such as atherosclerosis, that can cause both heart disease and stroke.Hypertension: Vitamin C lowers the blood pressure and decreases the probability of hypertension as well as serious health problems that may accompany high blood pressure.Blood Vessels: Vitamin C also ensures the proper dilation of the blood vessels which helps to protect us against certain diseases like atherosclerosis, high cholesterol, heart congestion and severe chest pains.Lead Toxicity: Vitamin C helps lower the level of lead in our blood dramatically. Lead toxicity can lead to various behavioral and developmental problems, especially in children living in urban areas. This leads to learning disabilities, lowered IQ and stunted growth in children. Adults may suffer from kidney damage and high blood pressure owing to lead toxicity.For Weight Loss: Vitamin C fruits and juices are proven to help people lose fat and maintain healthy weight. Popular dieticians and nutritionists always include Vitamin C fruits and vegetables in diet charts because there is scientific evidence that shows that eating Vitamin C rich foods on a regular basis helps in losing weight significantly. Doctors have found that eating Vitamin C fruits lowers insulin. Thus, instead of storing sugar and converting it into fats, it uses it as a fuel that leads to weight loss.Stress: Vitamin C helps the body deal with stress by reducing the elevated levels of stress, hormones and cortisol. Cataracts: Our eye pupils require Vitamin C to function properly. Vitamin C deficiency can lead to cataracts, where the lens become increasingly opaque, causing a blurry vision and leads to blindness in adults. A high intake of Vitamin C fights against cataracts and increases the amount of blood flow to the eye. 1000 mg Vitamin C per day stops cataracts in their tracks and improves vision.Cancer: Vitamin C’s antioxidant properties protect the cells from DNA damage and mutation and protect from cancer in the long run. It supports the body’s immune system and prevents certain cancer forming compounds from forming in the body. It reduces the risk of development of all types of cancers including lung, mouth, throat, colon, stomach and oesophagus. Vitamin C also helps to regenerate Vitamin E which is another powerful antioxidant. Vitamin C does not directly attack cancer that has already occurred but keeps the immune system nourished and enables to battle against cancer.Energy: Vitamin C balances our internal body systems under countless environmental conditions. It aids in the production of dopamine in the nervous system and supports the adrenal function for increased metabolic energy.Heart Disease: Vitamin C prevents heart disease by preventing free radicals from damaging the artery walls, which could lead to plaque formation. This nutrient also keeps the cholesterol from oxidizing, which can cause heart stroke. The problem of high blood pressure can also be resolved with this wonder nutrient. All these factors combine to make Vitamin C an inexpensive and easy way to lower the risk of heart disease and strokes.Diabetes: Diabetic patients can also benefit from Vitamin C as it helps in regulating the sugar levels, reducing the risk of getting diabetes and improving the symptoms of the existing cases. Supplementing Vitamin C forces glucose in the body cells, where it protects against many complications of diabetes.Asthma: People with low level of Vitamin C have a high chance of developing asthma. Greater intake of Vitamin C will lessen the body’s production of histamine which contributes to inflammation.Vitamin C Benefits For SkinVitamin C is the most important ingredient used in skin care treatments. Its ability to provide an effective shield against the sun has made it an indispensable ingredient used in the cosmetic industry.Sun Protection: Vitamin C protects our skin from free radicals that develop due to excess exposure to the sun, environmental pollution and regular smoking. The antioxidants in Vitamin C protect the skin from ultraviolet radiation and the effect of sunlight exposure.Vitamin C helps to reduce sun burns caused by the exposure to ultra violet radiation to a great extent. It not only reduces sun burns but also prevents the consequences of long term sun exposure that can lead to skin cancer.Production Of Collagen: Vitamin C is a required component for the production of hydroxyproline and hydroxylysine, both of which are needed to bind the molecules that produce collagen. This, in turn, firms and tones the skin. Collagen deficiency makes the skin dull and lifeless. Collagen rejuvenates the skin from the roots and reduces wrinkles and symptoms of aging.Heals Wounds: The body uses Vitamin C to replace the damaged tissue and helps to heal the wound at a faster pace. Wounds that heal slowly indicate Vitamin C deficiency. Vitamin C improves the skin elasticity and helps to create scar tissue and ligaments for quick recovery.Protects Against Skin Discoloration: Vitamin C protects DNA from photo-chemical reactions that can lead to tumor, skin discoloration and several kinds of skin cancer. It also inhibits the production of Pyrimidine dimer that are the primary cause of melanomas in humans.It lightens dark discoloration like skin freckles and age spots and helps to get a younger and smoother skin.Improves Skin Texture: Collagen also provides the structure for the blood vessels. The tiny blood vessels under the skin carry oxygen and nutrients that keep the skin healthy. Without enough nutrients, the skin will become rough and dry. Creams containing Vitamin C improve the appearance and texture of the skin.Vitamin C increases the formation of elastin which thickens, protects and heals the skin cells. The thickening effect helps retain moisture, increases the skin circulation and plumps up the skin surface.Vitamin C Benefits For HairIn order to get a healthy mane, we need to eat healthy food. A healthy diet reflects in our skin and hair. Vitamin C is more than an antioxidant and plays an important role in improving the health of our skin and hair. Vitamin C provides many benefits for the hair.Improves Hair Growth: Low intake of Vitamin C may be a root cause for a number of hair-related problems that affect our hair growth. Vitamin C deficiency may result in dry hair and split ends. These conditions are unfavorable for the regular growth of hair.When our body turns food that we consume into glucose for energy production, free radicals are naturally formed. These free radicals damage our hair by making it weak, brittle and thin. These conditions interrupt hair growth. Vitamin C’s antioxidant properties reduce the formation of free radicals and minimizes their effect on our body. Having an adequate supply of Vitamin C in our diet is essential for antioxidant protection against free radicals.People who take huge amount of Vitamin C have healthy, strong and thick hair.Fights Dandruff: Our hair follicles often get clogged due to dandruff and dry, flaky skin. This can damage the hair follicles if not treated, and also inhibit the hair growth. Vitamin C helps fight the bacteria on the scalp. It wards off dandruff and helps to get rid of the follicles’ debris and encourages the growth of new hair. It also helps with dry and itchy scalps because of its antiviral properties.Stops Hair Loss: It is used to reverse adrenal gland fatigue. This is crucial for stopping hair loss and encourages more hair growth since the adrenal glands are the key to maintain proper hormonal balance.Thicker Hair: It also helps improve the blood circulation and strengthens and repairs the capillaries too. This is particularly important for getting stronger, thicker hair.Fights Hair Disorders: Vitamin C is an essential nutrient for damaged hair and thus, treats and prevents a variety of hair disorders which can damage the hair follicles and affect the normal growth of hair. A diet containing significant levels of Vitamin C can help combat alopecia and baldness in men.Prevents Greying Of Hair: Vitamin C not only helps combat hair loss but also helps retain the natural color by preventing the premature aging of the hair.Now that you know the benefits of Vitamin C, make sure you are taking it in the recommended amounts.

Why Children and Adult Need Vitamin D

Dr. Nishant Mahajan, Pediatrician
Children need vitamin D for bone growth and development. So do babies developing in the womb. This is because vitamin D helps us absorb calcium.Serious vitamin D deficiency can cause rickets, delayed motor development, muscle weakness, aches and pains, and fractures.Vitamin D deficiency in adults has also been linked to osteoporosis, some cancers, heart disease and diabetes.If women don’t get enough vitamin D during pregnancy, their children might develop neonatal hypocalcaemia (not enough calcium in the blood) or rickets later in childhood.Vitamin D and sunlightYou need sunlight on your skin for your body to make vitamin D. You get about 80% of your vitamin D this way.The amount of sun you need depends on where you live in, and the time of year.But no matter where you live, you have to be careful about how much sun you get on your skin. Too much sun can lead to sunburn, skin damage and even skin cancer.Children might be at risk of vitamin D deficiency if they:keep all their skin coveredspend most of their time indoors and don’t get much or any sunhave a condition affecting how the body controls vitamin D levels – for example, liver disease, kidney disease, problems with absorbing food (such as coeliac disease or cystic fibrosis and some medicines can affect vitamin D levelshave darker skinhave been breastfed for a long time and have a mother whose vitamin D is low.Signs of vitamin D deficiency include rickets, delayed motor development, muscle weakness, aches and pains, and fractures.Treating vitamin D deficiency: Talk with your Pediatrician if you’re worried about your child’s vitamin D levels, or you’re pregnant and think you might have low vitamin D.Your doctor can order a blood test, which is the best way to check vitamin D levels.For mild deficiencies, your doctor might say that your child needs to get a bit more sun.If you or your child has a severe vitamin D deficiency, your doctor might say you or your child should take vitamin D supplements, as well as getting more sun.If you or your child can’t get more sun, the doctor might say that taking vitamin D supplements is the best thing to do. You might take a vitamin D supplement in one large, single dose, or you might take a supplement for several weeks or months.

Get Your Daily Dose of Vitamin C Fixed

Dr. Narendra Mahara PT, Physiotherapist
Good for a cold?Your immune system needs vitamin C to work right. But extra won't help you avoid a cold, unless maybe you're an extreme athlete, live in a very cold place, or you just need more anyway. Supplements might shorten a cold or ease its symptoms -- if you were taking them before you got sick.Prevents cell damage Vitamin C helps you get rid of chemicals that damage your cells and DNA. It's considered an antioxidant: It neutralizes "free radicals" in your body created by pollution, cigarette smoke, sunlight, radiation, and simply turning food into energy. That could help keep many parts of your body working better for longer and protect you from diseases, including Alzheimer's and cancer.Builds skin, bones, muscles, and moreYour body would fall apart without the protein collagen. Collagen fibers twist around each other to form scaffolding for your bones, cartilage, skin, and muscles (including your heart). They're also in ligaments, tendons and blood vessels. You need collagen to grow new skin and make scar tissue when you get cut and to keep your skin from getting wrinkles. And your body can't make collagen without vitamin C.Brain boosterYou need vitamin C to make key hormones that carry signals from your brain all over your body. These include serotonin, dopamine, epinephrine, and norepinephrine. They affect your mood, memory, motivation, and how you feel pain. For example, serotonin plays a role in keeping your daily sleep cycle on track. It's also what a common drug for depression works on.May preserve sightThe vitamin A in carrots isn't the only thing that's good for your eyes. Some studies show that vitamin C might slow age-related macular degeneration (AMD) from getting worse, but it won't prevent the disease. Other studies suggest a link between vitamin C and a lower risk of cataracts.Fights cancerVery high doses of vitamin C, especially through an IV, may slow the growth and spread of cancer cells. It can help chemotherapy and radiation work better. It may help you feel better and have fewer side effects, too. But it can also make treatments less effective. The FDA hasn't approved vitamin C as a cancer treatment, so check with your doctor to see if this therapy makes sense for you.Here are some ways by which you can fix your daily dosage of Vitamin C and no, they don't include only tangerines:From fruits Look beyond the usual oranges, grapefruits, lemons, and limes. Berries -- strawberries, raspberries, blueberries, cranberries -- are also good sources. So are papaya, kiwi, pineapple, cantaloupe, plums, and watermelon. Even bananas, apples, and pears have some.Fresh and raw are best because vitamin C breaks down over time and when heated.From VeggiesBell peppers are big winners. Load up on leafy greens (kale, Swiss chard, collards, and the like), cabbage, and bok choy. Crunch into broccoli, cauliflower, and Brussels sprouts. Tomatoes, sweet potatoes, and winter squash are also good sources.It's better to steam or microwave vegetables if you're going to cook them. These methods tend to destroy less of the vitamin. How much do you need? Adult men should get 90 milligrams every day. Women need 75 milligrams, but more when they're pregnant or breastfeeding. Your body can't make it. But most people who eat a variety of vegetables and fruits daily get more than enough vitamin C from their food.If you want to take a supplement, look for the inexpensive ascorbic acid form. Check with your doctor about how much is right for you.Smokers need more When you smoke, you'll have lower levels of vitamin C in your body. It may be because you have more free radicals to get rid of. You should aim for an extra 35 milligrams every day to make up for it.People who are around smokers are also affected and should try to get more vitamin C, too.Too little in body Through the 1700s, sailors on long trips would die from scurvy because they had little or no vitamin C in their diet. It's uncommon today, but people who don't eat well or abuse alcohol or drugs might be low. Medical conditions, such as some cancers and kidney diseases, can also cause problems. Symptoms include being tired, swollen or bleeding gums, loose teeth, achy joints, thickened skin, bruises, and cuts that don't heal right.Too much in body Your body can't handle a lot of vitamin C, and you'll pee out what it doesn't use. More than 2,000 milligrams a day for adults can cause stomach trouble, belly cramps, and diarrhea. Big doses can also lead to kidney stones.Partner with other nutrientsPut red peppers in your spinach salad. Have some broccoli with your baked beans. Or add strawberries to your oatmeal. Vitamin C helps your body use the kind of iron found in plants, which doesn't get absorbed as easily as the kind in meat and fish.Vitamin C also teams up with other antioxidants, especially vitamin E and flavonoids. Bonus: They're often found in the same foods.

Vitamin – D, Essential for a Healthy Life

Dr. Ravindranath, Diabetologist
VITAMIN D is an organic chemical compound, when it can’t be synthesized in sufficient quantities by an organism & must be obtained through diet. Vit. D is not essential dietary vitamin in strict sense. It is synthesized in adequate amounts by most mammals when they are exposed to sun. Surprisingly, cats and dogs can’t synthesize vitamin D and must receive it in diet. As with other compounds called vitamins, vitamin-D was discovered as to find the dietary substance that was lacking in a disease, namely, rickets.Vitamin D (Sunshine Vitamin) is a group of fat soluble secosteroids responsible  for intestinal absorption of calcium and phosphate (from food to blood stream)Two forms are:-D2 – ERGOCALCIFEROL & D3 – CHOLECALCIFEROLRegular sources are:-Diet Supplements / Fortified foods: e.g. margarine, some cereals, infant formula milk.SunshineIf one is at home, or it’s winter time, one may not be getting vitamin D from the following sources:Vitamin D3 (cholecalciferol) is produced by UVB irradiation of precursor 7 – dehydrocholesterol. Our skin makes Vitamin D­3 and supplies about 90% of our Vitamin D. Vitamin D­3 is richly found in oily fish and cod liver oil.Vitamin D­2 (Ergocalciferol) is a derivative of erosterol, produced by fungi e.g. mushrooms. It is produced from ergosterol, by UVI. The fate for producing 25 (OH) D2 from D­2 is same as for 25(OH) D3.Vit-D sources are oily fishes (such as sardines, pilchards, herring, trout, tuna, salmon and mackerel), fortified foods (this means they have vitamin D added to them) such as margarine, some cereals, infant formula milk, cod liver oil, egg yolk, liver and mushrooms (contain small quantities vitamin D). However, UVB remains the richest & biggest source.Symptoms of hypovitaminosis-D:-Bone pain and muscle weakness are commonly seen. Low blood levels of the Vitamin have been associated with increased risk of death from CVD, cognitive impairment in elderly, severe asthma in children & a wide variety of cancers.Vitamin D deficiency can occur for a number of reasons:-One doesn’t consume the recommended levels of the vitamin over time.Strict vegetarian diet, because most of the natural sources are animal based, including fish and fish oils, egg yolks, cheese, fortified milk, and beef liver. Hypovitaminosis D is a risk factor for the development of depressive symptoms in older personsThe body makes vitamin D when our skin is exposed to sunlight. One may be at risk of deficiency if:-homebound, live in northern latitudes, wear long robes or head coverings (naqab, burka) for religious reasons, or occupation that prevents sun exposure.For a fair skinned person, 20-30 minutes of sunlight on the face and forearms around the middle of the day 2-3 times a week is sufficient to make enough vitamin D in the summer months. For people with darker skin and elderly, the amount of time needed exposed to sunlight to is much more.It is nothing the same as sunbath. The skin simply needs to be exposed to sunlight. The sunlight has to fall directly on the bare skin. Sunlight through a window is not enough.LimitationsOne has dark skin. The pigment melamnin reduces the skin’s ability to make vitamin D in response to sunlight exposure. Elder adults with darker skin are at high risk of vitamin D deficiency.Kidneys cannot convert vitamin D to its active form. With ageing, kidneys are less able to convert vitamin D to its active form, thus increasing their risk of Vitamin D deficiency.Digestive tract cannot adequately absorb vitamin D.Certain medical problems, including Crohn’s disease, cystic fibrosis, and celiac disease, affect intestine’s ability to absorb vitamin D from the food.Obesity- Vitamin D is extracted from the blood by fat cells, altering its release into the circulation. People with a body mass index of 30 or greater have low blood levels of vitamin D.Certain medicines which interfere with Vitamin D. These include:-CarbamazepinePhenytoin,Primidone,Barbiturates and,Antivirals for HIV infection etc.Serum levelsSerum concertration of 25 hydroxy vitamin D (Calcidiol) is used to determine Vitamin D status. It reflects Vitamin D produced in the skin and acquired from the diet (half life of 15 days). It does not reveal the amount of vitamin D stored in body tissues. The level of serum 1,25 dihydroxy vitamin D is not used to determine vitamin D status (half life of 15 hours) and is regulated by parathyroid hormone, calcium & phosphate, so it is not decreased significantly until vitamin D deficiency is well advanced.2,5 Hydroxy vitamin D blood test.20 nanograms / milliliter to 50ng/mL – adequate for healthy peopleLess than 15ng/mL – vitamin D deficiency(mild to severe)10-15 ng/mL       -     mild5-10 ng/mL         -     moderate<5 ng /mL           -      severeTreatmentIt aims at getting more vitamin D – through diet & supplements. A concentration of less than 20 nanograms per milliliter is considered inadequate, requiring treatment. The safe upper limit is 4000 IUs to optimize bone health.If one don’t spend time in the sun or always covering the skin (sunscreen inhibits vitamin D production), vitamin D supplement may be required.Inadequate nutritional intake of Vitamin D coupled with inadequate sunlight exposure (inadequate UVB rays) results in disorders that limit Vitamin D absorption, and conditions that impair the conversion of Vitamin D into active metabolities includes certain liver, kidney, and hereditary disorders. Deficiency results in impaired bone mineralization and leads to bone softening disease including rickets in children and osteomalacia and osteoporosis in adults.Deficiency - Bone diseasesRickets, a childhood disease characterized by impeded growth and deformity of the long bones.The earliest sign of subclinical Vitamin D deficiency is craniotabes i.e. abnormal softening or thinning of the skull.Osteomalacia (bone – thinning disorder) exclusively in adults.There is proximal muscle weakness and bone fragility.Osteoporosis, a condition characterized by reduced bone mineral density and increased bone fragility.Muscle aches and weakness (in particular proximal limb girdle)Muscle twitching (fasciculations)RequirementTo prevent rickets and possibly also a wide range of chronic non skeletal disease.600 IU of Vitamin D / day for those 1-70 years.800 IU for those over 70 years of age.1 IU vitamin D is the biological equivalent of 0.025µg cholecalciferol / ergocalciferol. Pregnant or breast feeding women consider taking 2000 IU / day. All babies who are exclusively breastfed receive a supplement of 400 IU/day. Obese individuals have lower levels of the of Vitamin D, because of reduced bioavailability & are at risk of deficiency. To maintain blood levels of calcium, therapeutic vitamin D doses are administered (up to 100,000 IU or 2.5 mg daily) to patients who have had their parathyroid glands removed (renal dialysis, primary hyperparathyroidism) or with hypoparathyroidism.Patients with chronic liver disease or intestinal malabsorption disorders also require larger doses of vitamin D (up to 40,000 IU or 1mg daily).The use of sunscreen with a sun protection factor (SPF) of 8, inhibit more than 95% of vitamin D production in the skin. Wearing full clothing prevents skin exposure to UVB and reducing vitamin D synthesis.The clothing worn on a consistent and regular basis, such as the naqab, burqa is correlated with lower vitamin D levels and increased prevalence of Hypovitaminosis D.Reduced pigmentation of light skinned individuals results in higher vitamin D levels, because melanin acts like a sun-block. Dark skinned individuals, may require extra vitamin D to avoid deficiency at higher latitudes. The natural selection hypothesis suggests that lighter skin colour evolved to optimize vitamin D production in extreme northern latitudes.Vitamin D deficiency causes osteomalacia (rickets in children). Low serum vitamin D levels cause falls, and low bone mineral density. There is not enough evidence to indicate that healthy postmenopausal women should use supplemental doses of calcium or vitamin D to prevent fractures. Supplementation with Vitamin D and calcium may improve bone mineral density slightly, as well as decreasing the risk of fractures in people, older than 65 years.No benefit to bone health from Vitamin D without sufficient calcium.Multiple sclerosisHypovitaminosis D is associated with multiple sclerosis (MS).Supplementation with Vitamin D have a protective effect. Reasons follows:MS frequency increases with increasing latitude, which is inversely correlated with duration and intensity of UVB from sunlight and vitamin D conc.Prevalence of MS is lower than at high latitudes in populations with high consumption of Vitamin D rich fatty fish.MS risk seems to decrease with migration from high to low latitudes.Hypovitaminosis D associated with some cancers (prostatic) and worse outcomes in other cancers. Low levels of Vitamin D in pregnancy are associated with gestational diabetes, pre-eclampsia and LBW. Pregnant women who take an adequate amount of vitamin D during gestation, experience positive immune effects.OthersInfluenza – for high rates for influenza infection during the winter.Viral Infections – factors include low relative humidities produced by indoor heating and low temperatures that favour virus spread.Low levels of Vitamin-D is a risk factor for tuberculosis.Asthma – low levels of vitamin D.Supplemental Vitamin D is recommended in promotion of human hair growth.Rickets - A childhood diseaseImpeded growth, soft, weak, deformity of the long bones that bend and bow under their weight as they start to walk. This condition is characterized by bow legs, which can be caused by calcium or phosphorus deficiency as well as a lack of vitamin D. It is found in low-income countries in Africa, Asia or the Middle East. OsteomalaciaAdults with chronic musculoskeletal painSoftening of the bones, leading to(1)     Bending of the spine,(2)     Bowing of the legs,(3)     Proximal muscle weakness,(4)     Bone fragility, and increased risk for fractures. Osteomalacia reduces calcium absorption and increases calcium loss from bone, which increases the risk for bone fractures(25-hydroxyvitamin D levels < 10 ng/mL).OsteoporosisIt is defind as decrease in bone mineral density and the appearance of small holes in bones due to loss of minerals.There is vitamin D inadequacy (<10 ng/ml).Osteoporosis and osteomalacia are closely associated.There is higher risk of fractures and bone loss.Supplementing with Vitamin D increase bone density & can significantly improve the reduction in risk of osteoporotic fractures (especially hip fractures).ToxicityVitamin D overdose causes hypercalcemia, and so are the symptoms, e.g. anorexia, nausea and vomiting polyuria, polydipsia, weakness, insomnia, nervousness, pruritus & renal failure.Proteinuria, urinary casts, azotemia and metastatic calcification (especially in the kidneys).Mental retardation in young children,Abnormal bone growth and formation,Diarrhea, irritability, weight loss, & severe depression.SummaryIt is important for good health, growth and strong bones. Vitamin D is mostly made in the skin by exposure to sunlight. Most foods contain very little vitamin D naturally, though some are fortified with added Vitamin D.A mild lack of Vitamin D may not cause symptoms but can cause tiredness and general aches and pains. A more severe lack can cause problems such as rickets (in children) and osteomalacia (in adults).Treatment is with Vitamin D supplements.Special care forSome people are more at risk of Vitamin D deficiency and so are recommended to take Vitamin D supplements routinely. These include:All pregnant and breast feeding women All infants (babies) and young children aged 6 months to 5 yearsPeople who are above 65 years andPeople who are not exposed to the sun muchA doctor may also recommend routine supplements for certain people with darker skin and for people with certain gut, liver or kidney diseases.

Is Whey Protein Supplement Safe?

Ms. Swati Kapoor, Dietitian/Nutritionist
Whey Protein is the latest buzzword in Indian fitness. But many people wonder if whey protein is a safe supplement? Read on to find out all about whey protein.How whey protein is made? Whey protein is a natural component of milk, so it comes from a natural source of cow’s milk. It is a byproduct of cheese making process.Why is whey protein good for the body? Whey protein is easily digested and easily absorbed by the body, and is the best source for muscle growth and repair. In fact, whey protein has been around for a long time. Whey protein is even used in Indian nutritional drinks for children, like Bournvita and Complan. Can we consume any whey protein? No, ensure that you are getting high quality whey protein. To ensure that your whey protein is safe and high quality, there are 2 ways: the first is to go for a popular international supplement brand. The second is to look at the ingredients. We only recommend international brands of whey protein, since Indian protein supplement manufacturers are yet to produce a high quality & an equally good tasting whey protein supplement. Then, look at the ingredients, because some manufacturers will have a big ‘whey protein’ printed on the box, but whey protein will only be a part of the protein supplement. The remaining supplement is usually cheaper protein from plant sources (non whey protein), that is not effective for muscle building. Read to know more about muscle building food.As a result, you will not get the results, and due to lower quality protein, it puts you at risk of side effects. This is a practice of many local whey protein brands in India. Always go for a 100% whey protein supplement. So, how do you ensure you get high quality whey protein? Buy from internationally reputed brands. Also, when you buy whey protein, buy from a proper source, like a reliable whey protein supplement store, not the local supplement peddler. Peddlers often buy empty boxes of supplements and fill them with low quality protein.
