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 to 2 tablets daily with a meal.

Perfect for me

I have been using this product for several years and it works very well. I need a tablet form, rather than the gel form that so many Vitamin D supplements have. Would highly recommend for anyone who needs tablets, rather than "soft gels".

Normally use the Thorne brand of D3's but for a cheaper brand these seem to be just as effective.
