Primary outcomePrimary: Change in Serum 25-Hydroxyvitamin D [25(OH)D] — 10.14; -2.3 ng/mL
Summary
The aim of this study is to evaluate the safety and effectiveness of the SOLIUS System in improving serum levels of 25-hydroxyvitamin D in vitamin D deficient/ insufficient adults of various skin types.
The investigators will conduct a double-blinded randomized clinical trial in 100 adults to compare the changes in serum 25-hydroxyvitamin D levels between subjects who received and do not receive weekly exposures to Ultraviolet B Radiation (UVB) generated by the SOLIUS System for 16 weeks.
