About

The aim of the present study is to describe the bioavailability for the proprietary standardized maqui berry extracts Delphinol® and MaquiBright® enriched in anthocyanins and in particular delphinidins. The analyses are based on two selected key substances namely delphinidin-3-glucoside and cyanidin-3-sambubioside and their metabolism to phenolic acids.

The bioavailability of anthocyanins specific for Delphinol®/MaquiBright® was analyzed in plasma sample kinetics (at 0h, 0.5h, 1h, 1.5h, 2h, 3h, 4h, 6h and 8h after intake of 1000mg standardized maqui berry extract in capsules) in 12 healthy subjects.
