Vitamin D blood work

Posted by Reviewer1949165 on Jun 26, 2017 | Verified Purchase

I have been using Doctor's Best vitamins for a long time and seem to get the most advantage from them. I take the Vitamin D to strengthen the bones. Recent blood tests show my level to be in the middle of the normal range. So, it's doing it's job. I usually take 2 soft gel pills a day. But, I like to check it often to make sure it's not too much.

Thanks for your feedback!
