Gut Bacteria and Vitamins
Gut bacteria produces vitamins, including vitamin K and B, besides biotin through fermentation, which are absorbed into the bloodstream. This source of vitamins comprises only a small portion of the daily requirement, but the contribution can be significant in cases of low dietary vitamin intake.
A person who relies solely on the absorption of the gut-produce vitamins may suffer vitamin deficiency if they receive antibiotic treatment. This is because the antibiotics inhibit the growth of both the disease-causing bacteria and beneficial bacteria.3Sender, Ron, et al. ‘Revised Estimates for the Number of Human and Bacteria Cells in the Body.’ PLoS Biology, Public Library of Science, 19 Aug. 2016, www.ncbi.nlm.nih.gov/pmc/articles/PMC4991899
