Vitamin D3 Powder

Vitamin D is a fat-soluble vitamin, which is also regarded as a hormone precursor acting on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin". Vitamin D is the general name of a group of compounds with the same A, B, C, and D ring structure but different side chains. The structure of A, B, C, and D rings come from the cyclopentadiene phenanthrene ring structure of steroids. At present, there are at least 10 known vitamin D, but the most important is vitamin D2 (ergosterol) and vitamin D3 (cholecalciferol).

 

Vitamin D3 (cholecalciferol) is a fat-soluble vitamin best known for regulating calcium and phosphorus absorption, with a growing role in immune-support formulations as well. Unlike vitamin D2, D3 is the form structurally identical to what the body produces from sun exposure, which is why most supplement and fortification programs specify D3 over D2.

 

Sheerherb's Vitamin D3 Powder is manufactured as a microencapsulated concentrate, with the oil-based cholecalciferol dispersed in a gelatin-carbohydrate matrix for stability. We supply supplement manufacturers, food fortification programs, and feed premix producers sourcing vitamin D3 raw material at commercial volume.
