Vitamin D (as cholecalciferol) is a fat-soluble vitamin. It is known as the “sunshine” vitamin because it is formed in the body by the action of the sun’s ultraviolet rays on the skin. Vitamin D is converted in the liver to calcidiol as well as in the kidneys to calcitriol, which is actually the most active form of Vitamin D.
The effects of Vitamin D are targeted in the intestines and bones to promote calcium absorption. The major biological function of Vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, thereby helping to form and maintain strong bones. It promotes bone mineralization in concert with a number of other vitamins, minerals, and hormones. Without Vitamin D, bones can become thin, brittle, soft, or misshapen.
Vitamin D helps prevent skeletal diseases such as rickets in children and osteomalacia in adults which cause defects and weaken bones. Moreover, recent research indicates Vitamin D plays a crucial role by activating the body’s immune defenses by controlling T cell antigen receptor signaling and activation.

- If you are pregnant or lactating, consult a health care practitioner prior to taking this product.
- Vitamin D is a fat-soluble nutrient and can accumulate at toxic levels in fatty tissue; avoid excessive Vitamin D intake (only one case of Vitamin D toxicity has ever been reported at a level of intake under 40,000 IU per day).
- Occasional side effects reported with large doses of Vitamin D include a disorder known as hypercalcemia, which causes calcium deposits in soft tissues. Signs of the disorder include headache, weakness, nausea, vomiting, confusion, kidney problems and constipation. Consult your health care practitioner if you experience any of these symptoms after taking Vitamin D.
- Those with hyperparathyroidism should not take Vitamin D without consulting a physician. Those with sarcoidosis should not supplement with Vitamin D, unless a doctor has determined that their calcium levels are not elevated.
