Provide research about apigenin and sleep.

Apigenin may support relaxation and sleep onset, but the evidence for a reliable sleep benefit remains limited and unclear.

• 1. Chamomile and proposed mechanism: Apigenin is derived from chamomile and is described as a mild hypnotic. It is said to increase activity at chloride channels, hyperpolarize neurons, and increase GABA-related inhibition, which may quiet thinking and promote sleepiness. 1 2
• 2. Dose and timing: A commonly discussed dose is 50 mg about 30 minutes before bed. It is also described as part of a combination with magnesium threonate and theanine, though apigenin may be taken alone. 3 4
• 3. Estrogen-related caution: Apigenin is described as having anti-estrogenic effects. The discussion cautions that lowering estrogen could have unwanted effects, including on libido and cognition. 5 6
• 4. Limits of the research: The evidence is characterized as preliminary: the available papers are few and not in top-tier journals, and sleep data are described as mostly subjective rather than objective. The sleep benefit is therefore still unclear. 7
