Product Overview

  • Dietary Supplement
  • Bioactive form for Bone and Immune Health

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

1 capsule daily with a meal.

No more colds or flu

Posted by iJenNZ on Jul 31, 2012

I am taking one capsule per day of this product, in consultation with my doctor, and blood tests show that it is maintaining my vitamin D level in the upper normal range. At this level I can get through winter without contracting any cold or flu viruses that previously had been making me very ill. A definite thumbs up for this product.

Best vitamin since sliced bread!

Personally Vit. D3 works only in mega doses, three times daily.
