PG - 15154 LID - 10.1038/s41598-017-15264-1 [doi] LID - 15154 AB - In-vitro studies suggest that vitamin D reduces inflammation by inhibiting nuclear factor kappa-B (NFkappaB) activity. Yet, no trials have examined the effects of vitamin D supplementation on NFkappaB activity in-vivo in humans. We conducted a double-blind randomized trial (RCT) examining effects of vitamin D supplementation on inflammatory markers and NFkappaB activity in peripheral blood mononuclear cells (PBMCs). Sixty-five overweight/obese, vitamin D-deficient (25-hydroxyvitamin D [25(OH)D] 0.05). Results remained non-significant after adjustment for age, sex, and % body fat, and after further adjustment for sun exposure, physical activity, and dietary vitamin D intake. Although in-vitro studies report anti-inflammatory effects of vitamin D, our RCT data show no effect of vitamin D supplementation on inflammatory markers or NFkappaB activity in-vivo in humans.
