Resveratrol has become well known as the anti-aging compound, thought to be the secret ingredient of the Mediterranean diet and responsible for the French Paradox. Resveratrol is found in grape skins, blueberries, red wine and specific herbs. Each recommended daily serving of Cell Shield RTQ™ has the equivalent Resveratrol as drinking 294 glasses of wine (there is no alcohol in Cell Shield RTQ'M).
Quercetin is a plant-derived flavonoid found in fruits, vegetables, leaves, grains and chocolate. The richest natural sources are from red grapes, tomatoes, broccoli (among other green, leafy vegetables), and a number of berries; including cherry, raspberry and bog whortelberry. A recent study reported that organically-grown tomatoes contained 79 percent more Quercetin than traditionallygrown tomatoes.
