Bottom Line: Apigenin is a natural flavonoid found in chamomile, celery, and parsley that Dr. Andrew Huberman has made famous as part of his “sleep cocktail” (alongside magnesium threonate and L-theanine). It works by modulating GABA receptors and reducing anxiety without the grogginess of pharmaceutical sleep aids. At 50 mg before bed for $10–20/month, it’s a gentle, well-tolerated sleep support option.

Does apigenin actually help with sleep?

Andrew Huberman has discussed taking 50mg apigenin before bed as part of his sleep stack. Research suggests apigenin binds to GABA receptors and may reduce sleep latency.

What is the recommended apigenin dosage for sleep?

Andrew Huberman has mentioned taking 50mg before bed. Some users take up to 100mg, though clinical dosing data is limited. Start with 50mg and adjust based on response.

Is apigenin safe for men?

Some early research raised questions about apigenin's effects on aromatase, but Andrew Huberman has noted that at standard supplemental doses (50mg), the effects on hormones appear minimal.

Can you take apigenin with magnesium and L-theanine?

This is the exact sleep stack Andrew Huberman has publicly discussed – 50mg apigenin, 200mg magnesium threonate, and 100-400mg L-theanine. Many users report this combination is effective for sleep.

What is the best source of apigenin?

Chamomile is the richest dietary source of apigenin, which is why chamomile tea is associated with relaxation. Supplemental apigenin provides a standardized, more concentrated dose.

What Is Apigenin?

Apigenin is a flavonoid — a type of plant compound — found in high concentrations in chamomile tea, celery, parsley, and certain herbs. It’s actually the primary active compound responsible for chamomile tea’s calming and sleep-promoting effects, which have been recognized for centuries in traditional medicine.

Apigenin gained mainstream attention in the supplement world largely through Dr. Andrew Huberman, who includes 50 mg of apigenin as part of his pre-sleep supplement routine alongside magnesium threonate and L-theanine. This “Huberman sleep cocktail” has become one of the most replicated supplement stacks in the biohacking community.

Beyond sleep, apigenin has interesting anti-cancer, anti-inflammatory, and neuroprotective properties being explored in research. However, its most practical application for most people is as a natural, gentle sleep aid.

How Does Apigenin Work?

Apigenin binds to benzodiazepine receptors on GABA-A receptors in the brain — the same binding sites targeted by drugs like Valium and Xanax. However, apigenin is a much weaker and more selective modulator, producing calming effects without the sedation, dependency, or cognitive impairment associated with benzodiazepine drugs.

This GABA modulation reduces neuronal excitability, promoting relaxation and facilitating the transition from wakefulness to sleep. Apigenin also has mild anxiolytic effects through this same mechanism, helping to quiet the racing thoughts that often prevent sleep onset.

Additionally, apigenin has been shown to inhibit CD38, an enzyme that breaks down NAD+. This connects it to the longevity space, as preserving NAD+ levels is a major focus of anti-aging research. Some researchers theorize that apigenin’s NAD+-preserving effects could contribute to its health benefits beyond sleep.

Key Benefits

Sleep Quality Improvement

Chamomile extract (standardized for apigenin) has been shown in clinical trials to improve sleep quality. A 2017 study found that chamomile extract improved sleep quality in elderly adults. The effects are gentle — apigenin won’t knock you out like a pharmaceutical sleep aid, but it facilitates natural sleep onset and improves sleep quality without next-day grogginess.

Anxiety Reduction

A randomized controlled trial found that chamomile extract (containing apigenin) significantly reduced generalized anxiety disorder symptoms compared to placebo. The effects were modest but consistent, and importantly, without the side effects of pharmaceutical anxiolytics.

NAD+ Preservation

Apigenin’s ability to inhibit CD38 — the primary consumer of NAD+ in the body — means it may help preserve NAD+ levels without needing to supplement NAD+ precursors directly. This is an emerging area of research, but it adds an interesting longevity dimension to what’s primarily used as a sleep supplement.

Anti-Inflammatory and Anti-Cancer Properties

Laboratory research shows apigenin has anti-inflammatory effects through NF-kB inhibition and anti-cancer properties through multiple mechanisms including cell cycle arrest and apoptosis induction. These are primarily demonstrated in cell culture and animal studies, but they suggest broader health benefits.

Optimal Dosage and Timing

Dr. Huberman’s recommended dose is 50 mg of apigenin taken 30–60 minutes before bed. This is the dose most commonly used in the biohacking community for sleep support.

Timing: Always before bed. Apigenin’s calming effects are not suitable for daytime use if you need to be alert.

Huberman’s sleep stack: 50 mg apigenin + 145 mg magnesium threonate + 100–400 mg L-theanine, taken 30–60 minutes before bed. See our full breakdown of the Huberman Sleep Protocol.

Note: Some people find apigenin too subtle on its own. The combination with magnesium and L-theanine produces stronger effects than any single component alone.

Potential Side Effects

Apigenin has very few reported side effects at the 50 mg dose:

Mild sedation (which is the intended effect for sleep use)
Potential estrogenic effects at very high doses (not relevant at 50 mg)

Who should be cautious: People on sedative medications (additive effects), those on blood thinners (apigenin has mild anticoagulant properties), and pregnant women (insufficient safety data). Men taking very high doses should be aware of potential estrogenic effects, though this is not a concern at standard sleep doses.

Which Expert Protocols Include Apigenin?

Dr. Andrew Huberman is the primary expert associated with apigenin supplementation. He includes 50 mg as part of his pre-sleep routine, which he discusses on the Huberman Lab podcast. His full sleep protocol combines apigenin with behavioral interventions (light exposure, temperature manipulation) and other supplements.

The broader longevity community has also taken interest in apigenin’s CD38 inhibition properties, though this application is less established. For how apigenin fits into broader expert stacks: Longevity Expert Stacks Compared.

Best Apigenin Products

Apigenin is available from several supplement brands, typically in 50 mg capsules:

Frequently Asked Questions

Can you just drink chamomile tea instead?

Chamomile tea contains apigenin, but the amount varies widely and is typically much lower than the 50 mg supplement dose. You’d need to drink several strong cups to approach supplemental levels. Tea can be a good starting point, but for consistent dosing, a supplement is more reliable.

Is apigenin habit-forming?

No. Unlike pharmaceutical sleep aids (benzodiazepines, Z-drugs), apigenin does not appear to cause dependency or withdrawal. Its mechanism of action is much gentler than these drugs, and you can stop taking it without rebound insomnia.

Can men safely take apigenin?

Yes, at standard sleep doses (50 mg). The estrogenic concerns sometimes mentioned online relate to much higher doses used in cell studies. At 50 mg per day, there’s no evidence of meaningful estrogenic effects in men. Dr. Huberman, who recommends it, takes it himself.
