Vitamin C is best known as an antioxidant that can protect the body's cells and molecules from damage by free radicals. NOW® AlphaSorb-C® includes Transport C-PLUS®, a trademarked combination of Threonic Acid-enhanced, buffered (non-acidic) Calcium Ascorbate with Alpha Lipoic Acid. Threonic Acid is a Vitamin C metabolite that has been shown to enhance cellular uptake of Vitamin C. Alpha Lipoic Acid functions as a free radical scavenger that can help regenerate Vitamin C in the body and may also enhance its utilization. With this unique formula, NOW has created a well-absorbed and highly biologically available Vitamin C supplement.
From the FDA website: "Some scientific evidence suggests that consumption of antioxidant vitamins may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive."
As a dietary supplement, take 1 capsule 1 to 3 times daily, preferably with food.
