Acai
A polyphenol-rich Amazon berry prized for antioxidant support.
Acai is the deep-purple berry of an Amazon palm (Euterpe oleracea) native to the Amazon basin. The small, nutrient-dense fruits are valued for vitamins, minerals, fiber and concentrated polyphenols, and are commonly consumed as juice, puree or in dried and extract forms.
Rich in anthocyanins and other polyphenols, acai has been studied for antioxidant and anti-inflammatory activity and is investigated for potential protective effects on cellular and metabolic processes; uses and effects can vary by individual. Supplement products commonly provide standardized extracts (reported supplemental ranges around 900–1200 mg daily), but concentrations differ between preparations, so professional guidance is recommended for specific use.
At a Glance
Acai is the deep-purple fruit of the Amazonian palm Euterpe oleracea, harvested for its nutrient-dense berries and used traditionally across South America. The berries are rich in polyphenols—notably anthocyanins and proanthocyanidins—and are commonly consumed as juice, puree, extracts and supplements.

Origin & History
Acai (Euterpe oleracea) is a slender palm native to the Amazon basin, ranging from southern Central America into northern Brazil. The palm thrives in humid, often seasonally flooded lowland forests and produces small, deep-purple drupes that are harvested year-round, with a higher yield during the dry season.
Indigenous communities have relied on acai as both a dietary staple and a traditional remedy for centuries. Beyond the berries, local traditions use leaves and roots for a variety of treatments such as addressing bites, fevers and organ pains; the name açai—derived from a Tupi term meaning “fruit that cries”—refers to how the pulp is extracted. The fruit has long cultural importance in Amazonian diets and economies, and more recently its popularity has spread globally through juices, purees and concentrated supplements.
Composition & Active Compounds
Acai produces small, deep-purple drupes about 2 cm in diameter that form on multi-stemmed palms; the pulp and seed are the parts most commonly processed for food and supplements. Chemically, the berries contain carbohydrates, fiber, phytosterols, vitamins (including A and C), minerals (calcium and iron) and a rich mix of polyphenols—notably anthocyanins, proanthocyanidins and other flavonoids—which are studied for antioxidant and anti-inflammatory activity.
The berry pulp, rich in anthocyanins, is the part most used in supplements.
- Anthocyanins: pigmented flavonoids associated with antioxidant activity
- Proanthocyanidins: oligomeric polyphenols with antioxidant and anti-inflammatory properties
- Cyanidin-3-glucoside: a specific anthocyanin noted for strong free-radical scavenging
- Cyanidin-3-rutinoside: an anthocyanin derivative contributing to pigment and antioxidant effects
- Quercetin: a flavonoid with antioxidant and anti-inflammatory potential
- Orientin: a flavone glycoside with antioxidant activity
