Description
Vitamin D3 (Cholecalciferol) is a fat soluble vitamin obtained either from diet or by conversion of cholesterol to cholecalciferol in the skin by the action of ultraviolet B.
It is readily converted in the liver to 25 hydroxycholecalciferol and in the kidney to 1.25 hydroxycholecalciferol both requiring specific cytochrome p450 enzymes.? Both are considered to be the biologically active form of the vitamin.
Vitamin D is essential for maintaining blood calcium and phosphorus levels to promote healthy growth and remodelling of bone. Vitamin D is also thought to be involved in the following functions:
- Promotes calcium absorption in the intestines
- Proliferation, differentiation and apoptosis of cells
- Affects neuromuscular function and inflammation
- Positive effects on the immune system
Smart D3 is in a carrier of pesticide free Black Cumin oil to enable optimal intestinal absorption.
Optimal dosing is with breakfast on food or in juice.
