Native to the rainforests of southern Chile and Argentina, maqui berries are rich in anthocyanins, particularly delphinidin-derived compounds with antioxidant activity. Laboratory and animal studies suggest these compounds may influence oxidative stress, inflammation and metabolic pathways. Human research has reported potential benefits for post-meal blood glucose regulation and dry-eye symptoms, although findings vary across studies. Some experiments have also explored effects on gut bacteria and cellular protection, but these results have not been consistently confirmed in humans. Maqui products are available as powders, juices and concentrated extracts, yet no universally established effective dose exists. Larger, longer clinical trials are needed to clarify their benefits and long-term safety.
