Vitamin B6

Menstrual and women's health is the main area connected here, and any felt benefit should be read together with the human evidence base.

Some human supplement-context evidence is present and directly informs the score.

Findings to review with care

Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.

Side effects reported when this ingredient was used alone

Symptoms or adverse events reported in studies of this ingredient without another active ingredient.

Plasma pyridoxal-phosphate, pyridoxal, pyridoxine concentrations1 papers
Daily supplementation with 50 mg pyridoxine or pyridoxal-phosphate for one week in 12 healthy volunteers showed significant increases in average plasma pyridoxal-phosphate and pyridoxal after 3 and 7 days, but large inter-individual differences in kinetics were observed, potentially explaining differences in sensitivity to vitamin B6 toxicity.Human studies · Observational study
Adverse effect signal1 papers
Chronic high-dose intake of Vitamin B6 (>1g/day) is reported to cause dose-dependent, often reversible sensory neuropathy.Human studies · Study type not identified

Caution signals when used with another supplement or medication

These studies reported a negative change, reduced absorption, or another caution when substances were used together. They do not predict an individual outcome.

KetosisThe text mentions that 2-OPP formation appears to increase upon ketosis, which may contribute to ongoing neurotoxicity in treated patients.
IsoniazidInteractions with medications like isoniazid are mentioned as a cause of Vitamin B6 deficiency.
AntiepilepticsInteractions with certain antiepileptics are mentioned as a cause of Vitamin B6 deficiency.
