A synthetic, water-soluble form of vitamin B6, a nutrient the body needs for amino acid and neurotransmitter metabolism.
Why it’s used
Taken to meet daily vitamin B6 needs or to correct a documented deficiency.
What the evidence is for
correcting vitamin B6 deficiency and supporting normal metabolism.
What the evidence says
NIH ODS confirms vitamin B6 is required for normal metabolism and nerve function, and that deficiency causes recognized symptoms correctable by supplementation. Evidence for benefits beyond correcting deficiency, such as mood or cognitive claims, is weaker and not well established.

Context
