Known as the “Brain Building Amino Acid,” L-Serine is essential for preventing memory loss and enhancing learning abilities, as well as for its overall anti-aging power. For these reasons, it’s used for reducing the symptoms of Alzheimer’s disease and certain types of depression. As we age, Serine production in our brains can decrease, resulting in a deficiency that requires supplementation. But L-Serine isn’t just for our brains – it’s necessary to every one of our cells, and is required for your body’s metabolism of fat and for tissue growth. Because L-Serine assists in the production of immunoglobulins and antibodies, taking it supports your immune system in fighting diseases and infections.
