What the evidence says. Graded preliminary: nearly all anticancer, senolytic and brain effects come from cell and animal work. The few human trials test chamomile extract (which contains apigenin) for anxiety, not purified apigenin, and even those show modest, inconsistent benefits — direct trials of isolated apigenin for sleep or aging are essentially absent. (Preliminary evidence: Early or small human trials; promising but not yet conclusive.)
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.

Anti-aging / senomorphic effectGABAergic/senomorphic activity shown only in animals; no human trials of isolated apigenin for aging endpoints.
No established dose; supplements provide 50 mg once daily, often at night. Most human data come from chamomile extract standardized to ~1.2% apigenin (1100-1500 mg/day).
Apigenin is generally well tolerated at typical supplement doses and is consumed in foods, but long-term safety of concentrated supplements is untested. It inhibits CYP enzymes and may raise levels of drugs metabolised by them; theoretically it can add to the effects of sedatives, anticoagulants/antiplatelets and antidiabetic drugs. Chamomile sources can trigger allergy in people sensitive to ragweed, daisies or marigolds, and high doses are best avoided in pregnancy and before surgery. Educational only — always check with your doctor or pharmacist before combining Apigenin with any medicine.
Apigenin is most often taken for Mild calming / anxiety relief, Support for sleep quality, Theorized anti-aging (senomorphic), Antioxidant & anti-inflammatory. Chamomile's calming flavonoid, popular for sleep and anti-aging.

Is Apigenin safe? Any cautions or side effects?
Apigenin is generally well tolerated at typical supplement doses and is consumed in foods, but long-term safety of concentrated supplements is untested. It inhibits CYP enzymes and may raise levels of drugs metabolised by them; theoretically it can add to the effects of sedatives, anticoagulants/antiplatelets and antidiabetic drugs.
