L-carnitine

Meat, fish, chicken, and dairy products are rich sources of dietary L-carnitine. L-carnitine claim to be metabolism boosters that can help to lose weight and increase the athletic performance. It has been suggested that carnitine may improve insulin sensitivity and nerve pain in people with type 2 diabetes, increase fertility in men, lower mortality risk in those with ischemic myocardial infarction, or heart attack, result in mild cognitive improvements in older people. Carnitine is often promoted as an aid for weight loss, to improve exercise performance, and to enhance a sense of well-being.
