Brief Summary:
The efficiency of different vitamin D formulations in treating suboptimal vitamin D status in adult population will be determined. It will provide insights into the influence of formulation on vitamin D absorption.
A randomised controlled intervention trial will be conducted on at least 72 subjects (18-65 years) with suboptimal Vitamin D status. Subjects will be selected from a pool of subjects in Part 1 of the study, after completion of winter sampling.
Study subjects will be randomised into four study groups (at least 18 subjects per study group). Three different treatments will be compared with a control group, which will not receive any supplemental Vitamin D. The three tested Vitamin D preparations in the treatment groups will be (A) oil-based VALENS vitamin D; (B) water-based VALENS vitamin D; and (C) Vitamin D capsules with starch-adsorbed vitamin D (powder). All these products are commercially available. Prior to study, actual level of vitamin D will be determined using appropriate analytical method. The treatment will be with 1000 IU Vitamin D per day, for two months, in all three groups. Second serum vitamin D level will be determined on last day of the treatment, and compared with pre-treatment vitamin D level.
