UVB-exposed wheat germ oil increases serum 25-hydroxyvitamin D₂ without improving overall vitamin D status: a randomized controlled trial.

ABSTRACT:

Purpose

This study investigated whether UVB-exposed wheat germ oil (WGO) is capable to improving the vitamin D status in healthy volunteers.

Methods

A randomized controlled human-intervention trial in parallel design was conducted in Jena (Germany) between February and April. Ultimately, 46 healthy males and females with low mean 25-hydroxyvitamin D (25(OH)D) levels (34.9 ± 10.6 nmol/L) were randomized into three groups receiving either no WGO oil (control, n = 14), 10 g non-exposed WGO per day (- UVB WGO, n = 16) or 10 g WGO, which was exposed for 10 min to ultraviolet B-light (UVB, intensity 500-630 µW/cm²) and provided 23.7 µg vitamin D (22.9 µg vitamin D₂ and 0.89 µg vitamin D₃) (+ UVB WGO, n = 16) for 6 weeks. Blood was obtained at basel
