Registry summary
Recent studies suggest B-vitamins such as riboflavin to possess prebiotic-like effects. However, there is still a lack of understanding of the exact host health benefits vs. conventional systemically available vitamin forms. The present study explores the benefit of colon-delivered vitamin B2 vs. conventional vitamin B2 in comparison to placebo in an aging population on gut microbiota and metabolic activity as well as gut health.
