Not all forms of Vitamin D work equally well in humans. Vitamin D3(cholecalciferol) should be used in preference to Vitamin D2(ergocalciferol), researchers said in a study published in the October, 2006, issue of the American Journal of Clinical Nutrition. Vitamin D2 has been predominately used in North America for vitamin D supplements, but Houghton, LA and Vieth, R, authors of the study from Acadia University said that an increasing body of evidence suggests that vitamin D3 has a greater bio-efficacy. In this study the authors also claimed vitamin D2 is inferior to vitamin D3 because vitamin D2 in synthetic form is less stable and has more impurities, which could potentially lead to a high risk of toxicity.

Vitamin D has emerged as the "star supplement". It plays a key role in the proper absorption of calcium for strong bones and teeth and has been shown to support colon, breast, prostate, ovarian, heart and colorectal health. It also supports a health immune system in adults.

Vitamin D3 1000 IU

Vitamin D3 is responsible for regulating the calcium and phosphorus levels in the blood by their absorption from food and re-absorption of calcium in the kidney. It promotes bone formation and is essential in the development of strong bones. It also inhibits paraththyroid hormone secretion from the parathyroid gland. Vitamin D affects the immune system by promoting immunosuppression and anti-tumor activity.
