    Apigenin for Improved Sleep Quality

    Isolated apigenin has not been tested for sleep in humans; the reputation rests on chamomile.

    Overview

    Isolated apigenin has not been tested for sleep in humans; the reputation rests on chamomile.

    Verdict

    Insufficient evidence

    How It Works

    Weak positive allosteric modulation of GABA-A benzodiazepine binding sites produces mild anxiolysis and sedation.

    Dosing & Protocol

    Typical dose

    Recommended dose
    No validated dose - purified apigenin has never been tested for sleep
    Expected timeframe
    Not established

    Protocol

    studied dose
    Chamomile extract at 270-1500 mg/day, containing only small and variable amounts of apigenin
    evidence note
    Verdict is insufficient - no randomised trial of purified apigenin for sleep exists
    what happened
    Chamomile trials produced small and inconsistent sleep-quality changes, and the active constituent was never isolated, so nothing can be attributed to apigenin itself
    better first choices
    Magnesium glycinate and melatonin have direct randomised sleep data
    if you still trial it
    Use a standardised chamomile extract rather than isolated apigenin, keep it to a 2-4 week trial, and score sleep quality weekly

    Evidence

    What the studies say

    Chamomile extract trials show small and inconsistent sleep quality changes. No randomised controlled trial of purified apigenin for sleep exists.

    No studies are yet linked to both Apigenin and Improved Sleep Quality.

    Safety

    Caveats

    Chamomile can trigger allergic reactions in people sensitive to ragweed, daisies or chrysanthemums. It may add to the effect of sedatives and anticoagulants. Apigenin content varies enormously between preparations, so dose is unknowable in practice. Avoid in pregnancy.

    Less likely to help if

    Most people, given there is no established active dose; those with sleep apnoea or circadian misalignment in particular.
