Actinidia chinensis Fruit Extract
Also known as: Kiwi fruit extract, Kiwifruit extract, Green kiwi extract, Actinidia deliciosa extract
Effective Dosage
No established dose from provided studies
What the Science Says
Actinidia chinensis fruit extract comes from the green kiwifruit plant, native to China. Kiwifruit is naturally rich in vitamin C, dietary fiber, and a protein-digesting enzyme called actinidin, which may support digestive comfort and gut regularity. While whole kiwifruit has some research backing for digestive health, the concentrated extract form used in supplements has very limited published clinical evidence, so it is unclear whether supplement doses deliver the same benefits as eating the fruit.
What It Doesn't Do
No proven fat-burning or weight loss effect. Not a substitute for a fiber-rich diet. No solid clinical evidence it treats constipation better than dietary changes. Don't expect immune-boosting miracles — the vitamin C content in an extract capsule is unlikely to match what you get from eating actual kiwis. No evidence it detoxifies the body.

Absorption & Bioavailability
Unknown — no pharmacokinetic data available from provided studies. Actinidin enzyme activity may be partially degraded during extraction and digestion.
Red Flags to Watch For
- Only 1 clinical trial indexed on PubMed — extremely limited human evidence for the extract form specifically
- Widely used in over 1,000 registered supplement products despite minimal published clinical research — popularity does not equal proof
- People with latex allergy may experience cross-reactivity with kiwi (latex-fruit syndrome) — check with a doctor before use
- Standardization of extract potency varies widely between brands — no regulatory standard exists for actinidin or polyphenol content
- Marketing claims often extrapolate from whole fruit nutrition research, which may not apply to concentrated extracts at supplement doses
