PureWay-C® Sustained Release Vitamin C contains PureWay-C®, a newly discovered form of vitamin C consisting of highly absorbable vitamin C-lipid metabolites. Vitamin C-lipid metabolites have faster and more beneficial effects than other forms of vitamin C . PureWay-C® Sustained Release Vitamin C also contains citrus bioflavonoids and ascorbyl palmitate. Ascorbyl palmitate is a fat-soluble form of vitamin C that is able to be stored in lipid cell membranes for later use. Citrus bioflavonoids include the flavonones, such as hesperidin and naringin, as well as the polymethoxylated flavones, such as tangeretin and nobiletin. Bioflavonoids, and citrus bioflavonoids in particular, work in conjunction with vitamin C to improve absorption and boost its effects.
