The Influence of Food Matrix Delivery System on the Bioavailability of Vitamin D3
In Brief
A clinical study evaluating Vitamin D3, Whey protein-complex, and 3 other interventions for Vitamin D Deficiency. Completed, enrolled 30 participants across 1 site.
Detailed Summary
This study investigates the influence of different food matrices on the bioavailability of vitamin D. Although most vitamin D comes from skin synthesis in response to sun exposure, dietary intake is also important - especially during winter time where there is no endogenous production of vitamin D in Denmark. A way to maintain an adequate vitamin D status is to supplement either as tablets/droplets or as fortified food. However, there seems to be an inter-individual variation in response to supplementation. This study aims to investigate whether this variation in absorption of vitamin D may depend on delivery system.
