Unusual response: This is a very unusual reaction to Vit D. You are more likely to be reacting to the other ingredients in the supplement so look for a pure Vit D3 with minimal additives. Most adults need 5-8000 iu/day to get optimal levels of 50-80.

Improve function but: As best as I can tell, vitamin d has not been shown to raise WBC count. However, vit. D plays an important role in immune function and improves the function of wbc's. It is theorized that colds & flu are more common in winter because so many people become deficient in d at that time. While it seems possible that d might increase WBC count in some people, this is not something we see consistently. ...Read more

Any brand will do: Counter to what a salesperson might tell you, there's not much money to be made selling vitamin D.

For most, 1, 000-2, 000units each day should be fine. Take enough to bring your 25OH vitamin D above 30ng/mL. Don't check 1, 25 diOH vitamin D. ...Read more

Is it okay to take vitamin d supplements along with multivitamins?
