L-Carnitine is produced from amino acids present in the body. It burns fat for the release of energy for the body to function and is therefore, one of the more well known agents of weight loss. L-Carnitine is also believed to have an effect in the delay of Alzheimer’s disease. Conditions, such as angina, cause insufficient production of L-Carnitine. It is commonly found in breast milk, red meat and dairy products. Low levels of L Carnitine can cause cramps in the muscles, low blood sugar and tiredness. When using supplements of L-Carnitine, a person must use suitable amounts of Vitamins C and B, along with iron supplements. Proteins from animals and other foods, rich in nutrition will assist in meeting the required levels of nutrition.
