Pyridoxine is one of the chemical forms of vitamin B6, a water-soluble vitamin the body needs for protein, carbohydrate, and neurotransmitter metabolism.
Why it’s used
Taken to meet daily vitamin B6 requirements and address or prevent deficiency; also used by some for nausea related to pregnancy, under separate clinical guidance.
What the evidence is for
meeting vitamin B6 requirements and correcting deficiency.
What the evidence says
According to the NIH Office of Dietary Supplements, vitamin B6 is well established as essential to metabolic and nervous system function, and oral supplementation reliably corrects deficiency. Evidence for benefits beyond correcting deficiency, such as mood or premenstrual symptoms, is more limited and mixed.
Dose studied
1.3–100 mg — adult RDA up to the tolerable upper intake level, per NIH ODS.
Context
Clinical and nutritional reference intakes are built around the Recommended Dietary Allowance, with a tolerable upper intake level set due to nerve-related effects reported at high, sustained doses in some case studies.
