Aside from being a choline precursor, DMAE has several functions as an anti-aging supplement. It is a very efficient antioxidant and free radical deactivator. It stabilizes lysosome membranes, preventing the rupture of these scavenger bodies, which would result in the leakage of collected toxins and protein-damaging enzymes. DMAE also appears to bring about repair of damaged cell membranes. This nutrient also helps avert the formation of lipofucsin (brown pigment characteristics of aging) in the membranes. DMAE also helps sludging or clumping of red blood cells and makes more of them available for carrying oxygen to the tissues.
