    B-Complex Vitamins for Prolactin Regulation

    Vitamin B6 has historically been used to lower prolactin, but the human evidence is old and weak.

    Overview

    Vitamin B6 has historically been used to lower prolactin, but the human evidence is old and weak.

    Verdict

    Insufficient evidence

    How It Works

    B6 is a cofactor in dopamine synthesis, and dopamine inhibits prolactin release.

    Dosing & Protocol

    Typical dose

    Recommended dose
    Keep B6 below 100mg/day
    Expected timeframe
    8-12 weeks

    Protocol

    hard limit
    Keep B6 below 100 mg/day from all sources including any B-complex
    studied dose
    High-dose B6 (200-600 mg/day) in a few small mid-century studies
    evidence note
    Verdict is insufficient - and the doses involved are unsafe
    what happened
    Those studies reported prolactin suppression, but modern controlled replication is absent, and the doses used are well above the level at which B6 causes irreversible sensory peripheral neuropathy
    what to do instead
    Raised prolactin needs medical investigation - it can indicate a pituitary adenoma, hypothyroidism or a medication effect, and has effective prescribed treatment

    Evidence

    What the studies say

    A few small mid-century studies reported prolactin suppression with high-dose B6. Modern controlled replication is absent, and high doses carry neuropathy risk.

    No studies are yet linked to both B-Complex Vitamins and Prolactin Regulation.

    Safety

    Caveats

    B6 above 100mg/day daily long term can cause peripheral neuropathy.

    Less likely to help if

    Anyone with pathologically raised prolactin, which needs medical treatment, and people whose prolactin is medication-induced.
