Additional Information

Precursor for production of carnitine, which helps with fat-burning for energy. Lysine and methionine another essential amino acid are precursor compounds for the synthesis of carnitine. Carnitine is indispensable for energy metabolism, as it transports fatty acids from the cellular cytoplasm into mitochondria where the fat can be used for fuel. Adequate carnitine allows muscle liver and kidney cells to draw on both fatty acids and glycogen as fuel. Low levels of carnitine shift energy production to being more dependent on carbohydrates (glucose and glycogen), while high levels of carnitine improve fat-burning for energy purposes. As with diet-sourced lysine, carnitine is also contained in animal-sourced foods (meat, fish, fowl, dairy, eggs) and is readily absorbed. People consuming a low protein diet or a vegetarian/vegan diet will be consuming less carnitine, along with less of the precursor amino acids. May reduce recurrences of herpes simplex virus outbreaks, and may reduce severity of symptoms and duration of viral outbreaks. Once someone has become infected with herpes simplex the infection alternates between quiescent states, with no outward signs or symptoms, and flare-ups. These outbreaks involve viral synthesis of arginine-rich proteins. In theory, increasing dietary lysine would compete with absorption and retention of arginine, resulting in less arginine being available for viral outbreaks. Researchers also postulate a direct benefit from lysine, mechanism unknown. A 2006 review of the literature cited clinical trials supporting lysine for lowering recurrence rate and reducing severity and duration of outbreaks. (it also cited trials that did not report confirmation of the theory, but the majority of trials favored benefits from lysine.) For trials with daily doses ranging from 500 to 3,000 mg/day, and for periods of up to six months, reported benefits included a lower incidence of recurrences, severity and duration.
