Micronutrients & recovery
Vitamin D supplementation (50,000 IU weekly for 12 weeks) in healthy, vitamin D-deficient women significantly increases gut microbial diversity and shifts the microbiota composition toward a healthier profile by increasing Bacteroidetes and decreasing Firmicutes.
If you are vitamin D deficient, supplementation (50,000 IU weekly) can improve your gut health by increasing microbial diversity and favoring beneficial bacteria like Akkermansia and Bifidobacterium. This suggests that correcting vitamin D levels is not just about bones, but also supports a healthier gut environment.
Vitamin D supplementation significantly increased gut microbial diversity. Specifically, the Bacteroidetes to Firmicutes ratio increased, along with the abundance of the health-promoting probiotic taxa Akkermansia and Bifidobacterium.
Why this rating
Randomized controlled trial design with a healthy, specific population (n=80), though limited by lack of a placebo control group.
