Questions and answers on Polyphenols

Polyphenols are claimed to have antioxidant properties and are as such suitable for partial replacement of vitamin E supplementation in animal diets. Despite showing antioxidant properties in vitro there is no scientific evidence in vivo. The discrepancy is mainly caused by the low bioavailability of polyphenols and the lack of accumulation in target tissues. The impact on meat quality traits measured through final oxidation products does not prove any equivalence with vitamin E. Moreover polyphenols do not play any role in immune stimulation or reproduction. Scientists agree that polyphenols can’t replace vitamin E.
