Pros
In This Article
- +Anti-inflammatory flavonoid from parsley and chamomile
- +Promotes GABA-A receptor activity for natural sleep
- +Senolytic properties — clears zombie cells
- +Safe at 50mg daily in research settings
- +Pairs well with NMN for longevity protocols
Cons
- –Very limited human clinical trial data
- –Not well-absorbed in standard capsule form
- –Expensive per mg compared to basic supplements
Who Should Skip This
Pregnant or breastfeeding women should avoid apigenin. Those on blood thinners or thyroid medications should consult a doctor. If you are not already taking core supplements (D3, magnesium, omega-3), apigenin is not a priority.
Best Apigenin Supplements: Top 3
NordVital Score
Based on clinical evidence, value, and safety
Our Verdict: Apigenin is genuinely interesting for longevity and sleep but sits firmly in the experimental category. The human evidence base is thin. We recommend it only as part of an advanced biohacking stack after core supplements are already in place. Andrew Huberman's endorsement boosted its profile, but the science lags behind the hype.

- ✓Anti-inflammatory and anti-anxiety properties
- ✓Andrew Huberman Protocol: 50mg before bed
- ✓Synergistic with NMN for NAD+ optimization
CONS
- ✗Limited human RCTs — most data from cell studies and animal models

Apigenin Supplement Review 2026 — The Sleep + NAD+ Longevity Compound
Apigenin is a plant flavonoid from chamomile that has become a key component of evidence-based sleep stacks. Evidence tier: A. Huberman Protocol ingredient. Also functions as a CD38 inhibitor — preventing the enzyme that degrades NAD+, making it synergistic with NMN supplementation.
Mechanism of Action
💰 Best Price Comparison
Why We Recommend It
Huberman sleep protocol, CD38 inhibitor
Dose: 50mg nightly
- Sleep: Binds GABA-A receptors (same target as benzodiazepines but much weaker, non-habit-forming). Reduces sleep onset latency without grogginess
- NAD+ preservation: CD38 is the primary enzyme that degrades NAD+ in cells. Apigenin inhibits CD38 → preserves NAD+ pools. This makes it synergistic with NMN (which increases NAD+ production)
- Cortisol: Mild HSD11B1 inhibitor — reduces cortisol reactivation in tissues
Huberman Sleep Stack Context
Andrew Huberman publicly uses and recommends apigenin as part of his sleep protocol: Magnesium L-threonate or glycinate (300-400mg) + Apigenin 50mg + L-theanine (100-200mg), taken 30-60 min before bed. Apigenin’s role is GABA modulation for sleep onset.
Clinical Evidence
- Salari et al. 2021 (Phytother Res): Chamomile extract (containing apigenin) significantly improved sleep quality scores vs placebo in elderly patients
- Zick et al. 2011: Chamomile extract improved daytime functioning and reduced sleep disturbance in postpartum women
- In vitro + in vivo: CD38 inhibition by apigenin restores NAD+ levels comparable to NMN supplementation in some tissue models
Dose
- 50mg/day as part of sleep stack (chamomile-standardized extract or pure apigenin)
- Take 30-60 minutes before bed
- Pairs with Magnesium Glycinate and L-theanine for compounded sleep benefit
- For NAD+ preservation: can be taken morning or evening
Who Needs It
Best for: people who fall asleep okay but wake up mid-night, or those pairing it with NMN for a longevity stack. Not a sedative — won’t knock you out. More of a «calming signal» that makes falling asleep easier.

NordVital Verdict
RECOMMENDED
Apigenin earns its place in the longevity toolkit via CD38 inhibition — preserving NAD+ that would otherwise be degraded. Combined with its potent sleep-inducing effects via GABA-A modulation, it is ideally positioned as an evening supplement for those optimizing NAD+ and sleep simultaneously.
✓ Best For
NAD+ stackers (with NMN/NR), those with poor sleep quality, longevity enthusiasts
⚠ Consider Skipping If
Those needing to be alert after taking it — it induces drowsiness
