Article Synopsis
- The study aimed to compare how well vitamin D(2) and vitamin D(3) from fortified orange juice are absorbed in the body compared to supplements.
- Conducted with healthy adults, 64% started with low vitamin D levels, and the results showed no significant difference in vitamin D levels between those consuming orange juice versus supplements.
- The conclusion is that both forms of vitamin D are equally bioavailable whether taken in orange juice or capsules.
Context: Two reports suggested that vitamin D2 is less effective than vitamin D3 in maintaining vitamin D status.
Objective: Our objective was to determine whether vitamin D2 was less effective than vitamin D3 in maintaining serum 25-hydroxyvitamin D levels or increased the catabolism of 25-hydroxyvitamin D3.
Subjects And Design: This was a randomized, placebo-controlled, double-blinded study of healthy adults ages 18-84 yr who received placebo, 1000 IU vitamin D3, 1000 IU vitamin D2, or 500 IU vitamin D2 plus 500 IU vitamin D3 daily for 11 wk at the end of the winter.
