L-carnitine is a molecule produced in the brain, liver, and kidneys of humans. It improves the body's conversion of fat into energy. L-carnitine is necessary for heart and brain activity, as well as muscular movement and a variety of other bodily functions. L-carnitine can be converted to acetyl-L-carnitine and propionyl-L-carnitine by the body. However, it's unclear whether these additional carnitines have the same benefits. L-carnitine is used to raise L-carnitine levels in persons who have a low natural amount of the amino acid. Some people use L-carnitine for heart and blood vessel problems, serious renal illness, and a variety of other ailments, however there is no clear scientific evidence to back up these claims.
Types of L carnitine
The typical biologically active form of carnitine, L-carnitine, is found in your body, foods, and most supplements. Carnitine can also be found in the following forms:
- D-carnitine: This inactive form may produce a carnitine deficit in your body by preventing other, more helpful forms from being absorbed.
- Acetyl-L-carnitine (ALCAR) is the most effective type of carnitine for your brain. It may help those with neurological illnesses, according to research.
- Propionyl-L-carnitine: This type of carnitine is good for circulatory problems such peripheral arterial disease and high blood pressure. It may increase nitric oxide production, which increases blood flow.
- L-carnitine L-tartrate: Due to its rapid absorption rate, L-tartrate is often used in sports supplements. It may help with muscular discomfort and workout recovery.
Acetyl-L-carnitine and L-carnitine appear to be the most effective for most persons in general use. However, you must always choose the type that best suits your needs and objectives.
Benefits of L carnitine
- Pain in the chest (angina):
. L-carnitine, taken orally or intravenously, appears to increase exercise tolerance in persons with chest pain. In persons with cardiac syndrome X, taking L-carnitine combined with normal treatment appears to minimize chest pain and enhance exercise ability. This illness causes chest pain but does not result in a blockage of the arteries. Only a healthcare provider can administer IV products.
2. Heart failure:
Heart failure and the accumulation of fluid in the body (congestive heart failure or CHF). In persons with heart failure, using L-carnitine orally or intravenously appears to improve symptoms and boost exercise capacity. Only a healthcare provider can administer IV products.
3. Male infertility:
Conditions in a man that make it impossible for a female partner to become pregnant (male infertility). In guys with fertility issues, taking L-carnitine by mouth, alone or in combination with acetyl-L-carnitine, enhances sperm count and mobility. According to several studies, this improves the chances of becoming pregnant.
4. Inflammation of heart:
Inflammation (swelling) of the heart (myocarditis). Myocarditis can develop in children who have diphtheria. In these youngsters, taking DL-carnitine by oral appears to minimize the risk of myocarditis and death.
5. Helps with PCOS:
A hormonal disease that results in enlargement of the ovaries and cysts (polycystic ovary syndrome or PCOS). In some people who do not even respond to the medicine clomiphene, taking L-carnitine by mouth might boost ovulation and the likelihood of becoming pregnant. Additionally, consuming L-carnitine may aid with weight loss and blood sugar control.
- When administered for up to 12 months, L-carnitine is expected to be safe. It can induce stomach distress, heartburn, diarrhea, and convulsions, among other things. It can also generate a "fishy" odor in the urine, breath, and sweat. D-carnitine and DL-carnitine should be avoided. These carnitine variants may impede the effects of L-carnitine, causing symptoms similar to L-carnitine deprivation.
- When taken by mouth in the dosages prescribed by a healthcare physician while breast-feeding, L-carnitine may be safe. Infants have been given small quantities of L-carnitine in breast milk and formula with no documented negative effects. The long-term effects of excessive doses are unknown.
- L-carnitine may be safe when taken by mouth for a short period of time for children. It can be taken by mouth for up to 6 months with no side effects.
Adults have traditionally taken 2 grams of L-carnitine per day by oral. L-carnitine has been given to children in doses of 50-100 mg/kg per day by oral for up to a year. To find out what dose is best for a certain disease, speak with a healthcare provider.
L-carnitine is well known as a fat burner, yet there is conflicting evidence. It is unlikely that it will result in significant weight loss. Studies, on the other hand, back up its usage for health, cognitive function, and illness prevention. Supplements may also help persons with reduced levels, such as the elderly, vegans, and vegetarians. Acetyl-L-carnitine and L-carnitine are by far the most popular and appear to be the most beneficial of the several types.
