The açaí (Euterpe oleraceae Mart.) is a species of palm tree indigenous to the area surrounding the Amazon in South America. Its berries resemble grapes and ripen seasonally in similar fashion, progressing from green to a deep purple color.1 Modern scientific analysis has revealed that the açaí berry’s complete polyphenolic profile boasts a formidable array of beneficial compounds, including polyunsaturated and monounsaturated fatty acids (11.1% and 60.2%, respectively), along with 19 health-promoting amino acids.2

Touted commercially for years as a superfood, only recently has the açaí berry gained compelling scientific validation as an antioxidant powerhouse. Among the most recent findings:

  • After consuming a blend of açaí polyphenols, researchers recorded a three-fold increase in antioxidant capacity in the blood of healthy human volunteers.3
  • Antioxidants found specifically in freeze-dried açaí extract have been shown to enter human cells in a fully functional form and effectively neutralize free radicals at very low doses.4
  • Similarly, açaí extract has demonstrated unrivalled scavenging capacity against two of the most damaging reactive oxygen species, the superoxide and peroxyl radicals.

Evidence is also building for açaí as a major cancer fighter. Polyphenolic mixtures of açaí pulp and oil extracts inhibited the proliferation of human colon cancer cells in the lab by up to 90.7%5 and a study on human leukemia cells found açaí polyphenols reduced cell proliferation from 56-86%.6 Açaí pulp was also found to be protective when administered to mice prior to the chemotherapeutic drug doxorubicin.7

Açaí is also emerging as a major cardiovascular protector.8 In one study, açaí extract induced long-lasting endothelium-dependent vasodilation (relaxing of the arterial wall) in the abdominal vascular tissue of rats.9 Supplementation with açaí berries has also been shown to reduce total and non-HDL cholesterol in animals with experimentally induced high cholesterol.10

Açaí’s high antioxidant capacity also benefits brain function, with potential implications for the treatment of neurological disorders, including Alzheimer’s disease and Parkinson’s disease. Research has shown that pre-treatment of brain tissue from the cerebral cortex, cerebellum, and hippocampus with açaí decreased ROS-induced damage of lipids and proteins in all brain tissues tested.11
