Product Overview

  • Dietary Supplement
  • Supports the Immune System and Strong Bones

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 tablet 2 to 3 times daily, following a meal. Do not exceed suggested use.

Microcrystalline cellulose and stearic acid.

Soure Naturals was one of three produce names my physician recommended for Vitamin D3 supplements. Also provided was a list of web sites from which to order. iHerb.com was not included. However, I did my research and looking at total cost, Ifound your offer to be the best price with shipping of either $1.99 ro $2.00. Thanks from a satisfied customer!!!
