Swanson PureWay-C 1,000 mg with Bioflavonoids helps support the nervous system, skin and immune system health. This form of vitamin C is different than all previous forms because it employs naturally derived lipid metabolites, from vegetable waxes, to enhance the uptake, distribution and release kinetics of ascorbic acid. PureWay-C uses lipid metabolism to alter the lipid absorption potential of generally water-soluble ascorbic acid, thereby enhancing the vitamin's bioavailability unlike any other formulation. Lipid metabolites interact with cells in a non-toxic, safe and effective manner to enhance bioavailability of ascorbic acid. It's scientifically proven to scavenge up to 93% of free radicals!
