Apigenin Dosage: How Much Should You Take?

There is no single clinically established apigenin dosage. The most famous sleep protocol uses 50 mg before bed, while commercial supplements commonly range from 50 mg to 250 mg per capsule and some brands recommend 500 mg/day or more. The right way to interpret these numbers is by use case, formulation and evidence—not by assuming the highest dose must work best.

Apigenin dosage at a glance

Best apigenin dosage for sleep

If you are asking because of the Huberman sleep protocol, the number you are looking for is 50 mg, usually taken 30–60 minutes before bed. A 2026 human study also used 50 mg apigenin, but combined it with magnesium L-threonate and L-theanine.

The accurate wording is: 50 mg is the best-known sleep protocol dose, not a universally proven sleep-treatment dose.

Is 100 mg of apigenin a lot?

One hundred milligrams sits between the popular 50 mg sleep protocol and high-strength 200–250 mg products. There is no robust human dose-response trial showing that 100 mg produces twice the sleep effect of 50 mg.

What about apigenin 250 mg?

A 250 mg capsule is best understood as a high-strength apigenin format. It is five times the famous 50 mg sleep-stack dose, but that comparison reflects a different product strategy. People buying a high-strength, single-ingredient longevity supplement may value fewer capsules, simple formulation and a precise amount per capsule.

DoNotAge Pure Apigenin provides 250 mg per capsule. We rate its formula 5/5 and rank it #1 overall because of its clean single-ingredient composition, stated >99% batch-purity threshold, no listed fillers, batch testing, disclosed sourcing and GMP/ISO9001 manufacturing. See the full DoNotAge Pure Apigenin review.

What about 500 mg/day?

DoNotAge currently recommends 500 mg/day, or two 250 mg capsules. That is a simple high-strength two-capsule routine. It should be interpreted as a manufacturer’s recommended intake rather than a universal dose established by a human dose-response trial.

How much apigenin for longevity or CD38?

There is no clinically validated human “CD38 dose.” The major CD38/NAD+ findings come from experimental systems and mice. Translating an animal concentration directly into a human capsule dose is not scientifically sound.

When should you take apigenin?

• Sleep/relaxation: 30–60 minutes before bed is the most familiar protocol.
• General daily supplementation: consistency matters more than a precisely proven clock time.
• If it makes you drowsy: evening use is more practical.
• When testing tolerance: do not introduce it with several other new supplements at once.

Should apigenin be taken with food?

Apigenin has low water solubility and undergoes substantial intestinal and hepatic metabolism. Human pharmacokinetic work shows that isolated apigenin, parsley glycosides and chamomile glycosides have different absorption patterns. The food matrix and chemical form matter.

A practical approach is to follow the label and use a consistent routine. Read Apigenin Bioavailability for the full ADME data.

How long does apigenin take to work?

There is no validated onset time for isolated apigenin’s sleep effect. Human metabolism studies show apigenin-related metabolites can peak at different times depending on the chemical form and food matrix. That pharmacokinetic timing is not the same thing as onset of subjective relaxation.

What is apigenin’s half-life?

Numbers often quoted online come largely from animal pharmacokinetic studies and should not be presented as a definitive human half-life. Human research demonstrates extensive glucuronidation and sulfation and different absorption timing across forms.

Can you take apigenin every day?

Daily use is common in commercial products, but long-term high-dose isolated-apigenin trials are limited. Food exposure does not automatically establish the safety of concentrated 250–1,000 mg supplemental intakes over years.

Should you cycle apigenin?

There is no evidence-based cycling schedule. “Five days on, two days off” or monthly cycling rules are not established clinical protocols. Periodic reassessment is more rational than inventing a cycling rule.

Does body weight determine the dose?

No validated adult mg/kg equation exists for over-the-counter apigenin use. Do not convert animal mg/kg experiments directly into human doses.

Apigenin dosage with magnesium and L-theanine

The popular sleep stack commonly pairs 50 mg apigenin with magnesium and L-theanine 30–60 minutes before bedtime. The 2026 placebo-controlled combination trial did not establish a clear sleep advantage over placebo in healthy adults over two weeks, which is a useful reminder to test one ingredient at a time.

See Apigenin Sleep Stack.

Bottom line

50 mg is the best-known sleep-protocol reference. 200–250 mg represents a high-strength supplement format. 500 mg/day is DoNotAge’s current recommended two-capsule regimen. None should be misrepresented as a universally proven therapeutic target.
