Apigenin
Chamomile's calming flavonoid, popular for sleep and anti-aging.
What is Apigenin?
Apigenin is a sleep and mood supplement used for mild calming / anxiety relief. NutriDex grades the human evidence as Preliminary. Apigenin is a plant flavonoid concentrated in chamomile, parsley, celery and artichoke. In the lab it suppresses inflammatory signaling (NF-kB, p38-MAPK) and dampens the secretions of aging 'senescent' cells, which drives its popularity as a sleep and longevity supplement; it also shows GABA-receptor activity in rodents. Human evidence is thin and indirect. Trials use chamomile extract rather than pure apigenin: an 8-week RCT in generalized anxiety disorder found a modestly greater drop in anxiety scores than placebo (n=57, p=0.047), and a meta-analysis of 12 trials (965 people) saw benefit for anxiety and sleep quality but little effect on insomnia. A chamomile insomnia pilot found no improvement in objective sleep. No controlled trial has tested isolated apigenin for sleep or aging endpoints, and oral bioavailability is poor.

Evidence by outcome
The same supplement can be well-proven for one use and unproven for another — here is the human evidence graded outcome by outcome.
| Outcome | Evidence | Effect | Studies |
|---|---|---|---|
| Reduces generalized anxietyChamomile-extract (not pure apigenin) RCT and meta-analysis show modest anxiety benefit; borderline significance. | Preliminary | ↑ benefit · small | 2 |
| Improves sleep qualityMeta-analysis suggests subjective sleep-quality gain but an insomnia pilot found no objective sleep change; chamomile not isolated apigenin. | Mixed | ↔ mixed · small | 2 |
| Anti-aging / senomorphic effectGABAergic/senomorphic activity shown only in animals; no human trials of isolated apigenin for aging endpoints. | No Evidence | — no effect | |
| Anti-inflammatory / antioxidant / anticancerAnticancer and anti-inflammatory effects demonstrated only in vitro/animal models; no human data. | No Evidence | — no effect |
