Vitamin B6 (pyridoxine) is involved in over 100 enzyme reactions in the body, primarily related to protein metabolism, neurotransmitter synthesis, and immune function. Adequate B6 is critical for producing serotonin, dopamine, and GABA — key brain chemicals that regulate mood and sleep. Both deficiency and excessive supplementation can cause peripheral neuropathy, making monitoring important for those taking B6 supplements.
