Hi everyone, first I'd like to say thank you for all you do spreading awareness on Vitamin D.
I have a question about my levels, and how to get them higher.
My current blood test is 46.2 ng/ml, which puts me in the 40-60 ng/ml range that's recommended. However I'd like to get my levels up to 80-100 ng/ml.
I take 10,000 IU daily with a fat containing meal. I just started taking 10,000 IU daily a few weeks ago. In order to get my blood levels up to 80-100 ng/ml, what would a 175 lb male have to take to increase it to 80-100 ng/ml?
I read a study ("Vitamin D Supplement Doses and Serum 25Hydroxyvitamin D in the Range Associated with Cancer Prevention" in The Journal of Anticancer Research) showing that intake of 10,000 IU is needed to get to at least 40 ng/ml in a population group, and intakes of up to 40,000 IU are unlikely to result in toxicity.
So my question is to get to a Vitamin D level of 80-100 ng/ml, how much more Vitamin D3 would I need to take?
