Vitamin D3, also known as Cholecalciferol, is designed to help the body absorb calcium and phosphorus. In most cases, the vitamin is produced when the skin is exposed to ultraviolet B (UVB) light, triggering vitamin D synthesis from cholesterol in skin cells. However, for people who live in cities with high pollution levels, spend lots of time indoors, or live in areas with a 24-hour polar night, vitamin D deficiency can be solved through the addition of supplements.
Vitamin D2 comes from plant sources, while vitamin D3 comes from animal sources and is shown to more effectively raise the blood levels of calcifediol, which is the main circulating form of vitamin D.
Because calcium (the primary component of bones) can only be absorbed when vitamin D is present, this vitamin is imperative for promoting bone health. Proper absorption of calcium helps prevent bone disorders, such as rickets, osteomalacia, and osteoporosis. Studies have also shown a positive correlation between vitamin D consumption in reducing the risk for multiple sclerosis, heart disease, and the flu.
Vitamin D3 can be used to:
- Prevent bone disorders
- Raise blood levels of vitamin D
- Reduce inflammation
- Improve symptoms of depression
- Reduce the risk of disease
- Promote weight loss
