Quercetin-Bromelain Complex product image

Quercetin Bromelain Complex is a unique formulation of quercetin, buffered vitamin C and bromelain. Quercetin is a bioflavonoid that has excellent antioxidant activity. It prevents oxidation of lipids, prevents depletion of glutathione from the cells of the intestinal tract, and decreases free radical formation in endothelial cells, thus protecting them from oxidative damage. Quercetin, which is used in Herbal Medicine as a capillary protectant, can also support the health of the body's circulatory system by helping maintain proper vascular permeability, integrity and resiliency. Magnesium ascorbate is a buffered form of vitamin C, a key antioxidant that synergistically supports the quercetin activity. Bromelain is a proteolytic enzyme purified from pineapple, which is active and stable at the acidic levels found in the stomach. It assists in the breakdown of large macromolecular protein complexes, which reduces the chance that these complexes will leave the stomach untouched or in large fractions, while helping in their absorption.
