Product Description
Vitamin D consists of steroid derivatives. It is the general term for compounds with similar structures that facilitate normal skeletal growth and maintenance. Currently, at least ten types of sterols exhibit vitamin D activity. Two primary forms are essential: Pro-vitamin D2 (ergosterol), found in vegetable oils or yeast, which generates Vitamin D2 under UV radiation; and 7-dehydrocholesterol, found in the skin, which converts to Vitamin D3 (cholecalciferol) upon light exposure. While D2 and D3 have similar structures, D2's side chain includes a methyl group and an additional double bond.
Key Functions
Vitamin D is crucial for muscle and bone health. It significantly enhances calcium absorption in the small intestine. Without sufficient Vitamin D, the body may extract calcium from the bones to maintain necessary levels. Research indicates that Vitamin D may also provide protection against acute respiratory infections and pneumonia. Deficiencies are linked to an increased risk of infection and severe illness.

How should Vitamin D3 Oil be stored to maintain its potency?
It should be kept in its original sealed packaging in a cool, dry environment, protected from direct sunlight and moisture.
What is the difference between Vitamin D2 and D3?
