Vitamin B6 supports brain function, helps produce neurotransmitters, and assists in red blood cell formation. Because of these benefits, some people take supplements in doses far exceeding the recommended daily allowance (RDA), hoping to improve mood, reduce anxiety, or manage neuropathic pain. The RDA for adults is about 1.3 to 2 mg per day, but some supplements provide doses of 50 mg or more, sometimes reaching several hundred milligrams daily.

Vitamin B6 plays a critical role in several biochemical processes essential for health. One of its most important functions is supporting the activation of folate and facilitating methylation pathways. These processes are vital for DNA synthesis, gene expression, and overall cellular function
