Doctor's Best, Best Vitamin D3, 1000 IU, 180 Softgels

Posted by SeleneBrandt on Jan 28, 2015

Vitamin D is finally receiving the recognition it deserves. I need to supplement my vitamin D intake, especially during the winter. Doctor's Best comes in a small, round, easy to swallow soft gel.

I like the fact that you can vary doses if needed

I really like the 1000 mg of D3, you can vary it accordingly. The 5,000 and higher seems like I end up taking it just a few times a week and sometimes forgetting. With this one I either take 2 or sometimes 3 a day depending. Doing great with it.
