Overview

Doctor's Best Vitamin D3 delivers 2,000 IU (50 mcg) per softgel in a 180-count bottle, unflavored and swallowed as a capsule. It is labeled non-GMO, gluten free and soy free, marketed for immune and heart health support.

At 180 softgels per bottle and one softgel per serving, this is roughly a six-month supply for daily use, which is a different value proposition than smaller D3 bottles sold at similar per-unit prices. The 2,000 IU dose sits in the mid range compared with lower 1,000 IU and higher 5,000 IU D3 products on the market.

  • 2,000 IU (50 mcg) D3 per softgel
  • 180 softgels per bottle
  • Non-GMO, gluten free, soy free
  • 4.8 rating, 2,800 reviews

Who it's for

Fits someone who wants a plain, single-ingredient D3 softgel for daily long-term use rather than a gummy or a multivitamin blend. Less suited to someone who prefers a higher-dose D3 or a chewable format.
