This study shows that treatment with narrowband UVB light therapy leads to changes in the gut microbiome including increases to microbiota diversity, suggesting a novel skin-gut axis for promoting gut health.

The gut-skin axis: a bi-directional, microbiota-driven relationship with therapeutic potential
Gut Microbes
This review explores the gut-skin axis, describing the interaction that occurs between the skin and the gastrointestinal tract. Recent studies show that exposing the skin to ultraviolet B-light can beneficially modulate both the gut microbiome and intestinal health.

Effect of Vitamin D Supplementation on Human Gut Microbiota: A Systematic Review of Randomized Controlled Trials
Nutrition Reviews
This review article looked at 14 RCTs investigating the impact of vitamin D supplementation (dose ranging from 1680-7000 IU/day) on gut microbiota. They found that vitamin D supplementation modulates gut microbiota composition, with a significant increase observed in bacterial taxa associated with anti-inflammatory and gut health-promoting properties, such as Bifidobacterium and Lactobacillus as well as an increase in Bacteroides and Firmicutes ratio. Some trials also reported enhanced microbial diversity (α and β diversity).

The role of UVR and vitamin D on T cells and inflammatory bowel disease
Photochemical & Photobiological Sciences
This paper reviews how UV light and vitamin D impact inflammatory bowel disease. The authors conclude that the data suggests that UVR suppression of T cells and potentially IBD are both vitamin D dependent and independent.
