A member asked:
I have been taking 4000 iu daily of vitamin d3 for a month after my level was 29 ng/ml. is it safe to continue 4000 iu?

The answer is partly dependent on your ethnicity. From my experience, vitamin D level of 29 in colored people is not truly low but it is low in light skin people. If you have light skin, a daily 2,000 units a day after a month of 4,000 units/day for the initial level of 29 ng/ml is enough. If you have dark skin with initial level of 29 ng/ml, a daily dose of 1,000 units is enough.
