Nordic Naturals’ vitamin D3 formulas combine our industry-leading fish oil formulas with 1000 I.U. of vitamin D3 per serving. Why D3? Because the scientific community increasingly recognizes vitamin D3 deficiency as a worldwide epidemic. The human body is able to produce D3, but only after sufficient exposure to the UVB rays in sunlight. Factors that limit exposure to UVB—including working indoors, dark skin tone, wearing sunblock, and living in northern latitudes—can increase risk of vitamin D deficiency.*
Long known for its key role in building strong bones, vitamin D3 is also linked to many other key functions in optimizing health, including the regulation of the immune and neuromuscular systems, and the modulation of mood and circadian rhythms.* Vitamin D3 (or cholecalciferol) is the form of vitamin D that the body makes from sunlight, and experts agree that supplements containing the D3 form are better absorbed and more effectively utilized by the body.*
