How does PureWay-C work?
PureWay-C® is a novel vitamin C preparation containing vitamin C-lipid metabolites.
Studies in the laboratory show that human cells absorb this new form of vitamin C more rapidly and in greater amounts than the three most popular forms of vitamin C: ascorbic acid, calcium ascorbate and calcium ascorbate-calcium threonate-dehydroascorbate.
In order for vitamin C to exert its antioxidant benefits, it must be able to get inside cells.
PureWay-C® was tested for its ability to be taken up and retained in the cell.
Compared to ascorbic acid, the most common form of vitamin C, PureWay-C® showed a 233% increase in cellular uptake into human T-lymphocytes at both 30 and 45 minutes.
This absorption level was a 122% improvement above the next best form of vitamin C, calcium ascorbate-calcium threonate-dehydroascorbate.
