Gut microbiota & Vitamins

Concerning Gut microbiota & Vitamins, it was traditionally believed that dietary vitamins had little effect on gut flora. This was because vitamins are absorbed in the proximal small intestine, which appears to bypass the lower gastrointestinal tract where the majority of gut microbiota are located (1). However, recent human studies have shown that consuming high doses of vitamins may result in incomplete absorption. This allows vitamins to reach the distal gut, where they can directly influence the complex symbiotic relationships within the gut microbiota. These interactions can subsequently affect [neuroimmune…
