Summary

Despite the wide availability of vitamin D supplements vitamin D deficiency remains a concerning global problem. It is hypothesised that hypothesize that vitamin D delivered via the skin will overcome the problems associated with variable oral bioavailability and lead to a patient-friendly and efficacious means to supplement this vitamin. The main objective of this study is therefore to test the efficacy of a vitamin D transdermal patch that employs vitamin D phosphate to deliver the vitamin D into the blood.

In this two-part supplementation study healthy individuals with a risk of vitamin D deficiency (n=118), aged between 18 - 65 years, will be recruited. The recruitment in central London, UK, will ensure a multicultural, multi-ethnic cohort to enable the findings to be translated into evidence to try and find a solution for the global vitamin D deficiency problem.
