Life Extension Vitamin C is the best supplement for daily consumption because its formula gives your body 24 hours to make use of the vitamin. The product combines 350 mg of vitamin C with an innovative liposomal delivery system infused into a hydrogel. The hydrogel allows vitamin C to be absorbed over the course of 24 hours. This results in 7 times better absorption and 7 times greater total plasma levels than standard vitamin C supplements.
