Why was this study done? It can be difficult to measure the antioxidant ability of various substances. This study was designed to assess the accuracy and reproducibility of an antioxidant measurement system (MatTek EPI-100). What did the study find? The study found that the MatTek EPI-100 was a good assessment tool for determining antioxidant ability…
Why was this study done? The grape polyphenol resveratrol is demonstrated to influence the activity of multiple cellular signaling pathways including those involved in cellular aging. Grapes and red wine, however, contain complex mixtures of polyphenols of which resveratrol represents a very minor component. It is possible that complex mixtures of polyphenols have different cellular…
Why was this study done? Meals that are high in fat and carbohydrates are well-known to increase oxidative stress and inflammation. This study was designed to explore the notion that an antioxidant supplement high in polyphenols and resveratrol principally from muscadine grapes could blunt the oxidative effects of a high fat/carbohydrate meal. What did the…
Why was this study done? AREDS2 is a formula that contains vitamin C, E, zinc, copper, lutein, and zeaxanthin. AREDS2 has been shown in multiple studies to help people prevent macular degeneration. This study was designed to discover if the addition of a mixed polyphenol preparation (resveratrol, quercetin…) to the AREDS2 formula would be beneficial.…
