Best Apigenin Supplement 2026: Sleep, Anxiety, and the NMN Stack

Apigenin is a plant-derived flavonoid quietly becoming one of the most discussed supplements in longevity and sleep circles. Found naturally in chamomile, parsley, and celery, apigenin caught mainstream attention when Andrew Huberman included it in his sleep stack on the Huberman Lab podcast — 50mg before bed, alongside magnesium threonate and theanine.

But apigenin’s utility extends beyond sleep. It inhibits CD38, an enzyme that degrades NAD+ precursors, which makes it a relevant addition to NMN and NR longevity protocols. This guide breaks down what apigenin actually does, what the evidence says, and which supplements are worth buying.

What Is Apigenin?

Apigenin (4’,5,7-trihydroxyflavone) is a bioflavonoid found in many plants, with chamomile being the highest-concentration dietary source. As a supplement, it’s extracted and standardized to deliver therapeutically relevant doses — typically 50mg per capsule.

Its primary mechanisms of interest:

• GABA-A receptor modulation: Apigenin acts as a partial agonist at GABA-A receptors — the same receptors targeted by benzodiazepines and alcohol, but with much milder, non-addictive effects. This is the basis of its anxiolytic and sleep-promoting effects.
• CD38 inhibition: CD38 is a glycohydrolase enzyme that degrades NAD+ and its precursors (NMN, NR). Apigenin inhibits CD38, theoretically preserving NAD+ levels. This mechanism is why it appears in longevity stacks.
• Anti-inflammatory effects: Apigenin modulates NF-κB, a master inflammatory signaling pathway. Research suggests it has anti-inflammatory properties relevant to chronic disease prevention.
• Phytoestrogenic activity: Apigenin has weak estrogen receptor binding activity. At supplemental doses (50mg), this is generally considered benign, but high-dose use warrants caution in hormone-sensitive individuals.

Apigenin for Sleep: What the Evidence Shows

The sleep application for apigenin is primarily mechanism-based (GABA-A modulation) with limited direct human RCT data. Here’s what we know:

Animal studies have consistently shown anxiolytic and sedative effects from apigenin via GABA-A receptor binding. In rodent models, apigenin administration reduced anxiety behaviors comparably to diazepam at appropriate doses, without the same tolerance-building or dependence risk.

Human evidence for apigenin specifically at 50mg for sleep is limited. Most human research on apigenin as a sleep aid comes indirectly through chamomile extract studies (which contain apigenin plus other flavonoids):

• A 2017 RCT in Sleep Medicine found chamomile extract (270mg twice daily, standardized for apigenin) significantly improved sleep quality scores and reduced insomnia severity in older adults vs. placebo.
• A 2015 trial in postpartum women found chamomile tea improved sleep quality and reduced fatigue compared to controls.

The 50mg standalone apigenin dose has been popularized largely through Huberman’s protocol — which is informed by mechanistic reasoning and animal data, not a robust human RCT at that exact dose. That said, the mechanism is sound, the compound has an excellent safety profile at this dose, and anecdotal reports of improved sleep onset are consistent.

Apigenin for NAD+ and Longevity: The CD38 Connection

This is apigenin’s more scientifically substantiated benefit for longevity protocols.

The CD38 problem: As we age, CD38 expression increases dramatically. CD38 is highly efficient at degrading NMN, NR, and NAD+ itself. Research suggests age-related NAD+ decline is substantially driven by increased CD38 activity — not just reduced production.

Apigenin as a CD38 inhibitor: A key 2013 study in Cell Metabolism (Camacho-Pereira et al.) identified apigenin and quercetin as natural CD38 inhibitors. In mouse models, supplementation with these flavonoids preserved NAD+ levels in multiple tissues.

Practical implication: If you’re taking NMN or NR to raise NAD+ levels, taking apigenin alongside it may reduce the rate at which your body degrades those precursors — improving the ROI of your NMN stack. This is the primary reason apigenin appears in longevity protocols from David Sinclair’s lab and the biohacking community.

3. Renue by Science Apigenin — Best for NMN Stack

Renue by Science is a longevity-focused supplement company that specializes in NAD+ precursors and companion compounds. Their apigenin is specifically marketed as a CD38 inhibitor companion to NMN — they understand the mechanism and their supply chain is calibrated for the longevity buyer.

If you’re already using Renue’s NMN or NR products, buying their apigenin keeps the stack consistent and ensures supply chain compatibility.

G6 Composite Score: 7.7/10

Renue by Science scores well on transparency given its longevity-focused formulation ethos; value is moderate at the price point, and third-party verification is limited compared to NSF or Informed Sport certified options.

How to Use Apigenin

For Sleep

• Dose: 50mg
• Timing: 30–60 minutes before bed
• Stack: Pairs well with magnesium glycinate or threonate (200–400mg) and L-theanine (100–200mg) — the Huberman sleep stack
• Consistency: Daily use appears safe; no evidence of tolerance development

For NAD+ Support (NMN/NR Stack)

• Dose: 50mg
• Timing: Take with your NMN or NR dose — typically morning
• Stack: NMN (500mg) or NR (300–500mg) + apigenin (50mg) + quercetin (500mg) — a standard CD38-inhibitor stack
• Note: Human evidence for the combination is still emerging; this is a mechanistically-informed protocol

Comparison: Apigenin vs. Chamomile Extract

For sleep specifically, chamomile extract RCTs used 270–540mg chamomile extract, which contains much less apigenin than a 50mg standalone supplement. The standalone apigenin protocol is a higher-dose, targeted application.

Who Should Consider Apigenin

Strong candidates:

• Anyone on an NMN or NR stack looking to maximize NAD+ outcomes
• People seeking non-pharmaceutical sleep support without grogginess
• Those already using magnesium and theanine who want to add the next tier of sleep optimization
• Longevity-focused users following Andrew Huberman, Peter Attia, or David Sinclair-style protocols

Use caution or consult a doctor:

• People on blood thinners, antidepressants, or hormone-sensitive medications (CYP1A2 interaction potential)
• Individuals with estrogen-sensitive conditions (mild phytoestrogenic activity)
• Those with thyroid conditions (apigenin has shown thyroid effects in rodent studies at high doses)

Frequently Asked Questions

What is the best apigenin supplement? Double Wood Apigenin is the best overall pick for most users — 50mg per capsule, third-party tested, and priced under $0.20 per serving. For the highest quality standard, Thorne Apigenin (NSF Certified) is the premium choice. For NMN stack users, Renue by Science offers good synergy with their longevity product line.

Is apigenin safe long-term? Apigenin at 50mg/day appears safe based on available evidence. It has a long history of human exposure through dietary sources (chamomile, parsley, celery). No significant adverse events have been reported at supplemental doses in human studies. Long-term (multi-year) standalone supplementation studies are limited, but the safety profile is considered favorable at this dose.

Does apigenin cause drowsiness during the day? At 50mg, apigenin generally does not cause significant daytime sedation when taken at night. The GABA-A modulation effect at this dose is mild compared to pharmaceutical sleep aids. Some users report feeling slightly more relaxed, but not functionally impaired. Taking it in the morning alongside NMN (for the CD38 inhibition benefit) is generally well-tolerated without drowsiness.

Can I take apigenin every night? Yes — daily use is the standard protocol for sleep applications. Unlike pharmaceutical sleep aids, apigenin does not appear to build tolerance or cause rebound insomnia. Many users take it nightly as part of a consistent sleep stack.

What foods are high in apigenin? Chamomile tea is the highest dietary source, followed by parsley (one of the richest plant sources by weight), celery, oregano, thyme, and basil. However, even high dietary intake provides far less apigenin than a 50mg supplement — parsley provides approximately 225mg apigenin per 100g, but typical serving sizes are much smaller, and bioavailability from food varies.
