ORAC5.TM expands the ORAC platform to measure antioxidant capacity against five primary reactive oxygen species (commonly referred to as radicals)—peroxyl, hydroxyl, peroxynitrite, superoxide anion and singlet oxygen.
ORAC5.TM substantially improves broad-spectrum antioxidant analysis and gives evidence of the diverse antioxidant potential of natural products against radicals other than peroxyl. In some instances this potential may be specialized (e.g. carotenoids vs. singlet oxygen); in other cases, there is balanced antioxidant performance against multiple radicals.
Brunswick Labs’ research shows that the antioxidants found in a wide range of natural products are effective against these primary radicals, and that in many cases a preponderance of a product’s antioxidant capacity is described by performance against the four new radicals added to the ORAC5.TM panel.
