Many Americans Fall Short on Their Vitamin D

For some perspective on vitamin D dosage, I asked Dr Vichinsky about this because I am quite deficient in D (level of only 19), and requested some advice. Dr Vichinsky told me that with the thal patients, they are now administering 50,000 IU of D weekly, because the smaller doses aren't having much impact. Interestingly, this jibes with the advice that our member Bigg has given. I am now starting on this regimen. I hope it helps because with the winter months coming, I need to correct my situation or I will be quite the depressed person, literally, because low D does also cause depression.

If I understand it well one should take 1 high dose of Vit D a week instead of all week long small doses?

I take the weekly dose of Vit D. But its too early to tell if there are any positive changes in me. Since i avoid sunlight completely, this will at least take care of deficiencies.
