L-carnitine tartrate is the purest form of l-carnitine available. It is an amino acid produced naturally by the body to help burn fat and increase circulation. The overall effect of its use within the body is to produce energy. It is thought to be used for muscle movement, as well as brain and heart function.
Because of the way acetyl l-carnitine is used throughout the body, it is also used as a vitamin or dietary supplement. Studies have indicated that l-carnitine tartrate may be effective for treating memory and nerve pain problems for the elderly, those with alcohol dependence, and those with diabetes.
Benefits of Amino Acids
There are a surprising number of potentially helpful effects of taking supplementary l-carnitine, however most scientists agree that the body tends to produce the proper amounts of the amino acid. There are some studies that have shown individuals to have a deficiency, but these are isolated and rare cases, or are a result of medication use. In general, l-carnitine supplements should only be taken with your doctor's approval.
Because l-carnitine is thought to help improve memory as well as improve muscle tone and burn fat, it is used widely as a dietary supplement. Intravenous use of l-carnitine seems to produce immediate, short term improvement in blood flow to the brain in people who have poor circulation in the brain. Some testing has been done with patients who have Alzheimer's disease, but results tend to benefit those with early onset Alzheimer's disease, under the age of 66.
There is no daily recommended dosage, but if you are using acetyl l-carnitine for a specific medical condition, your doctor should instruct you on how much to take and how often to take it. Dosage tends to fall within 1500mg â€“ 3000mg daily, taken in more than one dose throughout the day. For men with fertility issues, the dosage is higher, but depends on body weight and age.
