It is synthesized in the body from the amino acids lysine and methionine, primarily in the liver and kidneys, and then transported to tissues that require high amounts of energy—especially skeletal muscle, the heart, and the brain.\u003c\/p\u003e\n\u003cp data-start=\"420\" data-end=\"734\"\u003eIts primary function is to transport long-chain fatty acids into the mitochondria, the “power plants” of cells, where these fats are oxidized and converted into usable energy (ATP). Without adequate L-Carnitine, fatty acids cannot efficiently enter the mitochondria, limiting the body’s ability to use fat as fuel.\u003c\/p\u003e\n\u003cp data-start=\"736\" data-end=\"1132\"\u003eL-Carnitine is found naturally in foods such as red meat, poultry, fish, and dairy products. Vegetarians and vegans typically consume lower dietary amounts, although the body can produce its own supply under normal conditions. Supplemental forms include L-Carnitine, Acetyl-L-Carnitine (ALCAR), and L-Carnitine L-Tartrate, each with slightly different applications and absorption characteristics.\u003c\/p\u003e\n\u003chr data-start=\"1134\" data-end=\"1137\"\u003e\n\u003ch3 data-start=\"1139\" data-end=\"1155\"\u003e\u003cstrong data-start=\"1143\" data-end=\"1155\"\u003eBenefits\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ch4 data-start=\"1157\" data-end=\"1214\"\u003e1. \u003cstrong data-start=\"1165\" data-end=\"1214\"\u003eSupports Fat Metabolism and Weight Management\u003c\/strong\u003e\n\u003c\/h4\u003e\n\u003cp data-start=\"1215\" data-end=\"1550\"\u003eL-Carnitine’s most well-known benefit is its role in fat metabolism.
