Exposure to Sunlight Boosts Good Gut Microbiome Bacteria, and Vitamin D Levels
- “The results of the study confirmed that skin UVB exposure significantly increased gut microbial diversity, but only in the 12 subjects who were not taking vitamin D supplementation.”
- “UVB exposure boosted the richness and evenness of their microbiome to levels indistinguishable from the supplemented group, whose microbiome was not significantly changed.”

Change in Vitamin D levels when UVB was added
Note: Some who had high level of Vitamin D before had no change or even reduced levels after UVB
More of a species if higher Vitamin D (UVB or supplement)
