Abstract: A nutritional supplement is taught for treating chronic debilitating diseases such as HIV/AIDS to overcome conditions of oxidative stress, decreased lean muscle mass, decreased energy production (mitochondrial failure) and support immune function. It comprises orally administrable superoxide dismutase (SOD), preferably SOD/GLIADIN, in combination with other antioxidant/immune support components (Beta Glucans, Nucleotides, Fruit Polyphenols); High Immunoglobin Whey; (undenatured whey), Ornithine alpha ketoglutarate (OKG), Branched Chain Amino Acids and Glutamine to reduce loss of lean muscle mass; and Coenzyme Q 10, D-Ribose and L-Carnitine to provide energy support (decrease mitochondrial failure).
