- and vice versa

All the different B vitamins are of vital importance to our energy levels, nervous system, skin, hair, and health in general. Our daily diet is the primary source of the vitamins but the intestinal flora is able to synthesize, consume, and compete for vitamin B in the host. Interactions between the body and the gut flora is therefore important for how we absorb and utilize the different B vitamins. On the other hand, lack of B vitamins or supplementation with B vitamins can also affect our gut flora, according to a review article that is published in Frontiers in Nutrition.

Biotin, one of the B vitamins, is essential for numerous metabolic processes, and a biotin deficiency may be associated with inflammatory bowel disease (IBD). According to a new study that is published in Nutrients, a biotin deficiency can also have a negative impact on the intestinal flora and result in a suppression of symbiotic bacteria and a replication of harmful, dysbiotic bacteria. The scientists say that a disrupted gut flora caused by a biotin deficiency may contribute to inflammatory bowel disorders.
