    Apigenin for Poor Sleep Quality

    Apigenin is the flavonoid behind chamomile''s calming reputation, but isolated apigenin has almost no direct sleep trial data.

    Overview

    Apigenin is the flavonoid behind chamomile''s calming reputation, but isolated apigenin has almost no direct sleep trial data.

    Verdict

    Insufficient evidence

    How It Works

    Apigenin binds benzodiazepine sites on the GABA-A receptor as a weak positive modulator, producing mild sedation without the potency of pharmaceutical agonists.

    Dosing & Protocol

    Typical dose

    Recommended dose
    No validated dose - apigenin content varies widely between chamomile preparations
    Expected timeframe
    Not established

    Protocol

    studied dose
    Chamomile extract 270-1500 mg/day in insomnia and anxiety trials
    evidence note
    Verdict is insufficient - no randomised trial has tested isolated apigenin for sleep
    what happened
    Small, inconsistent improvements in sleep quality, with the active constituent never identified and apigenin content differing widely between products
    better first choices
    Consistent sleep timing, morning daylight, magnesium glycinate and melatonin for circadian delay
    if you still trial it
    Use a standardised chamomile extract in the evening for 2-4 weeks and score sleep quality weekly so the result is measurable

    Evidence

    What the studies say

    Chamomile extract trials in insomnia and generalised anxiety show small, inconsistent improvements in sleep quality, and apigenin content varies widely between preparations. No randomised trial has tested purified apigenin for sleep in humans.

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

    Safety

    Caveats

    Allergy risk in people sensitive to the Asteraceae family. Possible additive sedation with benzodiazepines, antihistamines and alcohol, and additive bleeding risk with anticoagulants. Avoid in pregnancy.

    Less likely to help if

    People with sleep apnoea, restless legs, shift-work schedules or evening caffeine and alcohol as the real driver.
