This study of obese and normal weight women found that vitamin D levels were significantly associated with alpha and beta diversities of the gut microbiota and that serum vitamin D levels were positively associated with bacteria known to regulate immunological responses. These findings suggest that vitamin D may play a role in regulating the gut microbiota composition by inhibiting the growth of pathogenic bacteria while nourishing the beneficial strains.

Skin Exposure to Narrow Band Ultraviolet (UVB) Light Modulates the Human Intestinal Microbiome
Frontiers in Microbiology
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.

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 significant increase observed in bacterial taxa associated with anti-inflammatory and gut health-promoting properties, such as Bifidobacterium and Lactobacillus as well as increase in Bacteroides and Firmicutes ratio. Some trials also reported enhanced microbial diversity (α and β diversity).
