The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
skin exposure to narrow band ultraviolet light which is uvb modulates the human intestinal microbiome this is a small study but it's an interventional study okay they took um 21 females and gave one group vitamin d supplements and one group they exposed to three narrow band uv light exposures within the same week and the serum 25 hydroxy vitamin d levels of participants in both groups increased
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

suggesting the existence of a novel skin gut axis
humans with low serum 25 hydroxy vitamin D levels display overt changes in their intestinal microbiome in response to narrow band uvb skin exposure and increases in 25 hydroxy vitamin d levels suggesting the existence of a novel skin gut axis that could be used to promote intestinal homeostasis and health
