Formulation Notes
How it works: ProtoSorb C is a unique formulation featuring transport C-plus threonic acid, which has been shown to enhance uptake of vitamin C. This buffered, non-acidic vitamin C supplement also contributes alpha-lipoic acid, a free radical scavenger known to help regenerate both vitamin C and glutathione in the body. Studies suggest that Alpha-Lipoic Acid may further promote the body's utilization of Vitamin C, by activating uptake into cells via the glucose transport pathways.* Bioflavonoids also synergistically participate at the cellular level to create a well-absorbed, highly biologically available Vitamin C supplement.* Vitamin C is required for the synthesis of collagen, a structural component of blood vessels, tendons, ligaments and bone.
