What was ORAC used to measure?
Oxygen radical absorbance capacity (ORAC) was a method used to measure antioxidant capacities in biological samples, however, it has been withdrawn in 2012 due to the lack of physiological proof in vivo. Various foods were tested using this method, according to the Wikipedia article on ORAC. Research has also found that antioxidant-rich foods can help protect against oxidative damage and reduce the risk of chronic diseases.
Do USANA supplements have antioxidant activity?
USANA does not publish ORAC scores for its supplements because they only measure antioxidant activity, and do not take into account the value of vitamins and minerals. Sourced from Ask The Scientists, using an ORAC score to evaluate a product like USANA CellSentials would overlook the importance of its vitamin D, B vitamins, and mineral content. Nutritional value should be taken into account when evaluating supplements.
