Description
Vitamin D3 (as cholecalciferol) is a fat-soluble vitamin that's naturally present in very few food sources. It has many functions in the body from contributing to bone health to supporting immune function. NutraBio Vitamin D3 is the same form of Vitamin D3 the body manufactures when skin is exposed to ultraviolet (UV) sunlight. Vitamin D3 may be more than three times as effective than other forms of Vitamin D3 in raising concentrations in the bloodstream and maintaining those levels for a longer time.* Vitamin D3 is kosher, halal, gluten-free, lactose-free, third-party tested, and manufactured in the USA in a facility that meets FDA 21 CFR Part 111 c-GMP regulations. Like all NutraBio products, our Vitamin D3 supplement is tested by an independent third-party lab to ensure it is both pure and meets strict quality standards. All NutraBio products feature fully transparent labels with no proprietary blends.
