Tag: Gut bacteria vitamins

According to a study published in PMC, cobalamin (vitamin B-12) and its analogues are present in human feces, though they account for a small portion of the total cobalamin equivalents. The simple and complex answers to the question of what vitamins are in human feces depend on dietary intake, gut microbiome activity, and the body's absorption efficiency. This article will explore the specific vitamins found in fecal matter, distinguishing between unabsorbed dietary nutrients and those produced by gut bacteria.

While the vast majority of essential vitamins must be obtained from our diet, the human body is capable of synthesizing a few vitamins and using precursors to produce others. This ability, however, is limited and occurs in specific locations, primarily involving the skin and the gut microbiome. Understanding where vitamins are synthesized in the body is key to appreciating our complex relationship with nutrition and metabolism.
