What is the recommended dosage for Vitamin B6?

General: 1.3-2.0 mg/day (RDA); Cognitive Support: 25-100 mg/day

What are the side effects of Vitamin B6?

Potential side effects include: Peripheral neuropathy at chronic high doses (>200 mg/day), Photosensitivity, Nausea.

Vitamin B6 (pyridoxine) is an essential vitamin involved in over 100 enzymatic reactions, including the synthesis of neurotransmitters such as serotonin, dopamine, and GABA. Adequate B6 status supports cognitive function and is important for homocysteine metabolism alongside folate and B12.

What dosage of Vitamin B6 has been used in cognitive studies?

Cognitive studies have used 2 mg to 50 mg of vitamin B6 daily, often combined with folate and B12 to target homocysteine levels. The RDA is 1.3 to 1.7 mg for adults. Pyridoxal-5-phosphate (P5P) is the active coenzyme form. The tolerable upper intake is 100 mg per day. Consult your doctor.

What are the potential side effects of Vitamin B6?

Vitamin B6 is generally safe at recommended doses. However, chronic intake above 200 mg per day has been associated with peripheral neuropathy (nerve damage causing numbness and tingling). This is typically reversible upon discontinuation. Consult your healthcare provider for appropriate dosing.
