Quick answer
What is apigenin?
Apigenin is a naturally occurring plant compound — a flavone, which is one class of flavonoid (the pigments and polyphenols found throughout fruits, vegetables and herbs). It is best known as the flavone in chamomile, and it also occurs in parsley, celery and various other plants. In supplements it is usually a purified powder in capsules, sometimes standalone and sometimes as part of a longevity or NAD-support formula. Apigenin is sold as a food supplement in the UK with no authorised health claims, so this guide keeps to the facts: what it is, where it is found, its forms, and how to judge quality.
Key takeaways
- Apigenin is a botanical flavone — a type of plant flavonoid.
- It is the flavone most associated with chamomile; also found in parsley and celery.
- Supplement forms are usually purified apigenin powder in capsules.
- It commonly appears in longevity and NAD-support blends.
- Typical servings on the market are around 50mg per day.
- A UK food supplement with no authorised health claims — judge products on purity, dose and testing.
The basics
What apigenin actually is
Apigenin is a flavone — a subclass of the flavonoids, the widespread group of plant polyphenols responsible for many of the colours and characteristics of fruits, vegetables and herbs. Chemically it is a small, pale-yellow molecule (its name derives from Apium, the genus that includes parsley and celery).
Apigenin is one of the botanical flavones people encounter most, largely because it is the characteristic flavone of chamomile. It is a normal part of a plant-rich diet. As a supplement it is produced as a purified powder, typically standardised to a high purity and presented in capsules. It is sold as a food supplement in the UK and carries no authorised health claims, so — as with our other ingredient guides — this page stays factual about what apigenin is rather than what it might do.

In the diet
Where apigenin is found
Apigenin occurs across a range of everyday plants, herbs and drinks. The table below lists the sources it is most associated with. Amounts vary widely with plant variety, growing conditions and preparation, so these are illustrative rather than precise figures.
| Source | Type | Notes |
|---|---|---|
| Chamomile | Herb / infusion | The source most associated with apigenin; present in chamomile flowers and tea. |
| Parsley | Culinary herb | One of the richer dietary sources of apigenin. |
| Celery | Vegetable | Contains apigenin, particularly in the leaves. |
| Other plants | Various | Also found in smaller amounts in foods such as oregano, thyme and some fruits. |
| Supplement extract | Purified powder | Concentrated, standardised apigenin used in capsules and blends. |
Because dietary amounts are relatively small and variable, standardised supplement extracts are used where a consistent, measured amount is wanted — which is also why apigenin turns up in combination longevity formulas.
On the label
Forms & typical dose
Apigenin is a single, defined compound, so there is little form confusion. It is sold as apigenin powder in capsules — either on its own or, very commonly, as one ingredient within a broader longevity or NAD-support formula. The numbers to read are the amount per serving and the purity.

There is no official Recommended Daily Amount for apigenin, so the serving above reflects the market rather than a recommendation. In practice, many people meet apigenin through a combination product rather than a standalone one — for example our NMN Complete formula, which pairs apigenin with NMN, TMG and pterostilbene as complementary longevity ingredients.
Two numbers decide quality: how much per serving, and how pure.
Buying criteria
What to check before you buy
Because apigenin is a defined single compound, quality comes down to purity, an honest dose and proof of what is in the capsule.
- A clear amount per serving — e.g. "50mg apigenin per serving", so you can compare brands.
- A stated purity — ideally 98%+, verified rather than assumed.
- HPLC verification — the analytical method that confirms apigenin identity and purity.
- A Certificate of Analysis on request — batch-level proof of purity and contaminant testing.
- Transparency in blends — in a combination product, the exact apigenin amount, not just the blend total.
- UK manufacturing & accredited testing — ideally from an ISO/IEC 17025-accredited laboratory.
People researching apigenin often look at it alongside other longevity supplements and NAD-support ingredients; see our what is NAD guide for that wider context. Whatever you choose, buy on verified content and purity, not on the biggest number on the front of the pack.
Common questions
Apigenin FAQ
Apigenin is a flavone, which is a subclass of the flavonoids — the large family of plant polyphenols found across fruits, vegetables and herbs. It is a normal part of a plant-rich diet.
It is most associated with chamomile, and also occurs in parsley and celery, as well as smaller amounts in herbs such as oregano and thyme. Amounts vary with variety and preparation.
Usually a purified apigenin powder in capsules, standardised to a high purity. It is sold both on its own and as one ingredient within longevity or NAD-support blends.
A common serving on the market is around 50mg per day. This reflects what products offer rather than an established or recommended dose — there is no official RDA for apigenin. Consult a healthcare professional before starting any new supplement.
Formulators include apigenin as one of several complementary plant compounds in longevity and NAD-support blends — for example alongside NMN, TMG and pterostilbene in our NMN Complete. This is a formulation choice; it is not a health claim. Always check the exact apigenin amount in a blend.
As a general precaution apigenin is not recommended for anyone under 18, or during pregnancy or breastfeeding, and anyone taking medication or managing a health condition should speak to a healthcare professional first. Introduce one product at a time and follow the label serving.
