Andrew Huberman’s Views on Sleep Supplements

Andrew Huberman, as a neuroscientist and sleep researcher, often evaluates sleep supplements based on long-term health impacts and actual outcomes. He addresses melatonin frequently when discussing evidence-based sleep strategies.

Melatonin’s Popularity and Common Uses

Melatonin supplements, used by millions worldwide, commonly address sleep onset issues and jet lag. Many people take low to moderate doses, such as 0.5 mg or 3 mg, believing melatonin can regulate circadian rhythms and shorten time to fall asleep. Over-the-counter melatonin, found in tablets and gummies, represents one of the most widely consumed sleep aids in the United States (CDC, 2022).

Why Doesn’t Andrew Huberman Like Melatonin?

Andrew Huberman criticizes melatonin for several reasons tied to safety, effectiveness, and underlying biology.

• Endogenous Disruption: Supplemental melatonin, according to Dr. Huberman, can disrupt your natural production of the hormone, especially with long-term use.
• Dosing Concerns: Huberman explains most commercial melatonin supplements deliver supra-physiological doses—some gummies tested with actual content far exceeding labeled amounts—which can lead to unpredictable effects (JAMA, 2022).
• Hormonal Side Effects: He cautions that melatonin may affect other hormones, including puberty-related and reproductive hormones, because melatonin functions as a signaling molecule beyond sleep regulation.
• Unpredictable Sleep Benefits: Huberman often shares that people report inconsistent sleep improvements, with some experiencing morning grogginess or reduced sleep quality if using melatonin regularly.

Scientific Reasons Behind Huberman’s Stance

Huberman’s skepticism around melatonin comes from direct interpretation of high-impact neuroscience studies and clinical data. The focus stays on risks for you over time, with insights emphasizing measurable hormone changes and real-world effectiveness.

Concerns About Long-Term Use

Primary scientific concern centers on melatonin’s effect on your endocrine system. Research cited by Huberman (Sleep Medicine Reviews 2017; J Clin Endocrinol Metab 2001) shows melatonin supplementation may suppress endogenous melatonin production in the pineal gland if you take it regularly. This suppression links to irregular circadian rhythms and negative feedback loops in hormone secretion. Children's developing hormone profiles remain especially susceptible—studies (Hormone Research in Paediatrics, 2019) indicate puberty onset can shift with prolonged use in adolescent sleep trials. For adults, daily use longer than 12 weeks associates with persistent sleep disturbances post-discontinuation.

Potential Side Effects and Effectiveness

Most clinical trials measuring melatonin's effectiveness report only mild improvements in sleep latency for healthy adults. Data from meta-analyses (PLoS One, 2013; JAMA, 2017) show that average time-to-sleep falls by just 7-12 minutes, with no consistent gain in sleep quality or duration for most users. Huberman highlights dose inconsistencies in commercial supplements—published research (Journal of Clinical Sleep Medicine, 2017) confirms variable ingredient concentrations, leading to unpredictable effects and adverse outcomes. Side effects linked to melatonin include morning grogginess, dizziness, and possible interference with reproductive hormones, reported in 10-25% of long-term users in survey cohorts. Concerns over purity and unregulated compounds in widely available melatonin formulations further increase risk for you if you take the supplement persistently.

Alternative Strategies Recommended by Huberman

Huberman suggests concrete approaches for improving sleep quality without relying on melatonin. These strategies focus on behavioral routines, environmental cues, and safer supplementation practices.

Natural Sleep Enhancement Techniques

Huberman recommends natural sleep enhancement techniques for regulating sleep patterns and supporting circadian rhythms.

• Morning sunlight exposure: Getting 10–30 minutes of sunlight soon after waking boosts cortisol and sets your circadian clock, as confirmed by research from Stanford University.
• Evening light management: Dimming indoor lights and avoiding bright screens 60–90 minutes before bed reduces melatonin suppression, as supported by a 2021 PNAS study.
• Consistent sleep schedule: Going to bed and waking up at the same time daily enhances sleep efficiency, with evidence from sleep medicine journals.
• Pre-sleep wind-down: Practicing calming activities, like reading or non-stimulating stretching, signals your brain to transition into sleep mode.

Other Supplement Options

Huberman identifies alternative supplements with safer profiles and more reliable effects than melatonin.

• Magnesium threonate or bisglycinate: Taking 200–400 mg helps promote relaxation and sleep onset; cited in neuropharmacology reviews.
• Glycine: Consuming 2–5 grams 30–60 minutes before sleep aids in lowering core body temperature, contributing to deeper non-REM sleep.
• Theanine: Using 100–400 mg before bed assists in reducing mental chatter and anxiety for some users.
• Apigenin: A flavonoid found in chamomile, taken in doses of 50 mg, may calm neural activity according to studies published in the Journal of Clinical Psychopharmacology.

Frequently Asked Questions

Who is Dr. Andrew Huberman?

Dr. Andrew Huberman is a neuroscientist and professor at Stanford University. He is known for his research on brain function, behavior, and health optimization, and he hosts the “Huberman Lab” podcast, where he discusses evidence-based tools for improving sleep and overall health.

What are Dr. Huberman’s main concerns about melatonin supplements?

Dr. Huberman is concerned that melatonin supplements can disrupt the body's natural hormone production, especially with long-term use. He highlights unpredictable dosing, possible effects on puberty and reproduction, morning grogginess, and limited evidence for significant sleep improvements as major issues.

Are melatonin supplements safe for long-term use?

According to Dr. Huberman and clinical studies, long-term use of melatonin may suppress the body’s natural hormone production and alter circadian rhythms, with potential risks for both adults and children. Prolonged use could also cause persistent sleep issues after stopping the supplement.

Does melatonin help with sleep quality?

Most clinical trials show that melatonin only slightly reduces the time it takes to fall asleep (by about 7-12 minutes) and does not consistently improve sleep quality or overall sleep duration. Some people may also experience side effects like morning grogginess.

What are the alternates to melatonin recommended by Dr. Huberman?

Dr. Huberman suggests non-supplement strategies like morning sunlight exposure, reduced light in the evenings, a consistent sleep schedule, and relaxing bedtime activities. He also recommends alternatives such as magnesium threonate or bisglycinate, glycine, theanine, and apigenin for supporting sleep.

Is melatonin usage risky for children?

Dr. Huberman warns that long-term melatonin use in children may impact natural hormone production and potentially shift the onset of puberty, making it riskier for younger users compared to adults.

Why do commercial melatonin supplements raise concerns?

Dr. Huberman notes that commercial melatonin products often have inconsistent dosing and questionable purity, which can result in unpredictable effects and heightened risks of side effects or hormone disruption.
