Product Overview


  • Bioactive Form for Bone and Immune Health
  • Dietary Supplement

Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones; it increases muscle strength in older adults; and it also plays an active role in a healthy immune response. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body's needs.

Suggested Use

5 drops once daily in a drink.

All important ingredient

Posted by iHerb Customer on May 19, 2017 | Verified Purchase

Vitamin D is, in my opinion, a very important ingredient in so many processes going on in our body. My wife and I have used Source Naturals D-3 vitamin on a daily basis, year round, for several years already. We don't even think of quitting this daily routine, as we otherwise may have to spend the same amount of money, if not more, on remedies to cure sickness!

Thanks for your feedback!
