Uses For Ester-C & flavonoids Antioxidant Support:
Animal studies show increased plasma vitamin C concentration and delayed urinary excretion with administration of Ester-C, suggesting that it is readily absorbed and efficiently utilized. Calcium l-threonate, a metabolite of calcium ascorbate, may facilitate the transport and uptake of vitamin C, playing a key role in optimizing cellular levels. A human study involving 12 subjects indicated favorable bioavailability as well as revealing a boost in white blood cell levels. The bioflavonoids quercetin, rutin and pomegranate extract are powerful free radical scavengers that complement the roles of vitamin C. Quercetin helps maintain healthy histamine release and moderates healthy leukotriene and prostaglandin metabolism. Rutin and pomegranate extract provide important support for blood vessel integrity and healthy cell function.*
