My
vitamin D levels are 5.99(normal range-30+) and
Vitamin B12 are 212( Normal-211-911), hemoglobin -15.3. Symptoms are fatigue, tired even after sleep, memory and concentration problems. Are my symptoms due to vitamin D deficiency and B12 is also at the lowest point of Normal. Can Vitamin D deficiency affect sleep, memory and also cause fatigue? Also to mention i am taking cholecalciferol tablet 60000 IU for last 1 week and getting some relief. Also when i sit under the sun for sometime i feel more energetic. Please advise whether taking Vitamin B12 and D supplements could solve the problem.
