Maqui Berry at a Glance
Aristotelia chilensis, commonly called maqui or maqui berry, is a shrub or small tree in the Elaeocarpaceae family native to central and southern Chile and parts of Argentina. Its deep purple berries have a long food and traditional-use history in southern South America and are especially associated with Mapuche culture.
Parts & Chemistry
The berry is the best-known part in modern food and supplement use, although leaves also appear in traditional and research literature. Maqui fruit is notable for polyphenols and anthocyanins, particularly delphinidin derivatives, along with other flavonoids and phenolic compounds that contribute to its intense purple color and antioxidant activity measured in laboratory studies.
Traditional Use
Maqui has been used by Indigenous Mapuche communities for generations as both a food and a traditional botanical. Reviews describe traditional use of the berries and juice as nourishing, astringent and associated with digestive and general wellness practices. Modern commercial “superfruit” language should be kept separate from this cultural history and from what human trials can actually establish.
Human Research
Human research has expanded but remains relatively small. A 2026 systematic review identified 12 clinical trials published between 2014 and 2023. Acute studies showed a fairly consistent direction toward reduced post-meal glucose excursions and changes in insulin response, while longer-term effects on HbA1c, lipids and other cardiometabolic measures were modest or inconsistent. Trials have also reported changes in oxidative-stress biomarkers, and the most consistent clinical signal in that review was in ocular-surface studies involving tear production and dry-eye symptoms.
Anthocyanins & Bioavailability
Standardized maqui extracts rich in anthocyanins have been used in several studies. Human bioavailability research confirms that selected maqui anthocyanins and their metabolites can be detected after ingestion. A small randomized placebo-controlled trial also reported changes in oxidized LDL and F2-isoprostane markers after standardized maqui extract, supporting biological activity while not proving that maqui prevents or treats disease.
Food & Preparation
As a food, maqui berries can be used much like other dark berries when available, while commercial powders and extracts vary considerably in concentration and standardization. Whole-fruit use is not equivalent to a concentrated extract, so research on a named standardized product should not automatically be applied to every maqui powder, juice or supplement.
Safety
Short-term human trials summarized in the recent systematic review did not identify a consistent serious safety signal, but most studies were small, short and designed primarily to evaluate other outcomes. Long-term safety data remain limited. People taking glucose-lowering medicines should be cautious with concentrated products because some trials suggest effects on post-meal glucose. Pregnancy and breastfeeding safety has not been established for concentrated supplemental doses.
Traditional & Modern Context
Maqui is a good example of a traditional food plant that later entered the global supplement market. Its rich anthocyanin profile is real and human research is promising in several areas, but marketing claims often run ahead of the evidence. Respecting its Mapuche cultural history while keeping health claims evidence-based gives a more accurate picture of this South American berry.
Bottom Line
Aristotelia chilensis is an anthocyanin-rich traditional South American food with growing human research on glucose response, oxidative-stress markers and ocular health. The evidence is promising but still limited by small studies, short durations and differing formulations. Maqui belongs comfortably in a food-and-research discussion, but not as a proven treatment for diabetes, cardiovascular disease, dry eye or other medical conditions. For educational purposes only.
