VITAMIN D3 MORE POTENT THAN VITAMIN D2

VITAMIN D3 MORE POTENT THAN VITAMIN D2
A single blinded, randomised trial has shown Vitamin D3 (cholecalciferol) to be approximately 87% more potent in raising and maintaining serum vitamin D concentrations compared to vitamin D2 (ergocalciferol). Vitamin D3 also produces 2 – 3 fold greater storage of vitamin D than does eqimolar vitamin D2. The study supports vitamin D3 as the preferred choice for correcting vitamin D deficiency.
