Formulation

Formula re: Contains

Doctor's Best Sustained Release Vitamin C with PureWay-C supplies a unique form of the essential nutrient vitamin C that contains vitamin C lipid metabolites. PureWay-C has been studied in comparison to several other well-known forms of vitamin C. PureWay-C has superior uptake, bioavailability and retention in cells, as well as more potent free radical scavenging capabilities than other forms of vitamin C. This increased bioavailability means PureWay-C has the potential to more potently support healthy neuron function and enhanced immune system activity as compared to other forms of vitamin C.
