Dear Colleagues,

B vitamins have important functions in energy and amino acid metabolism, neuronal health and hemopoiesis. Although deficiency states are uncommon among the general population, B vitamins in different combinations are commonly prescribed or bought over the counter for health maintenance and clinical conditions, e.g., neuropathic pain, anxiety and depression. In addition, high doses of some B vitamins have been utilized for their therapeutic effects, e.g., enhancement of cognitive function or mood, lipid lowering, etc. Yet some B vitamins have harmful effects in higher doses. On the other hand, there has been increasing interest in the impact of vitamin B supplements on gut microbiota and interactions of vitamin B supplements with other nutrients, drugs and genetic factors.

For this Special Issue, we are interested in papers investigating how vitamin B supplements can impact on health both positively and negatively.
