Vitamin-D has a role in bone, tendon, ligament, nerve, muscle, and immune systems.
Vitamin D helps the body to absorb calcium. Calcium is one of the main building blocks of bone and an essential mineral for normal body functions.
The body gets vitamin D in 3 ways:
1. Through the skin
2. From diet
3. From supplements.
Causes:
1. No enough vitamin D in the diet
2. Malabsorption problem
3. Less exposure to sunlight
4. Liver weakness
5. Kidney weakness
6. Some drugs

Toxicity:
Signs of Vit D toxicity include nausea, vomiting, poor appetite, constipation, weakness, and weight loss. Excess vitamin D can also damage the kidneys. Too much vitamin D also raises the level of calcium in your blood. High levels of blood calcium (hypercalcemia) can cause confusion, disorientation, and problems with heart rhythm.
• Toxicity is caused by the overuse of supplements
• Excessive sun exposure doesn't cause toxicity because the body limits the amount
• Too much sun exposure can lead to skin aging and skin cancer.*-OKM*
