L-carnitine, also known as levocarnitine, is a naturally occurring amino acid structure that the body produces.
Shedding fat with l-carnitine
People can also get it from their diet or take it in the form of an oral supplement. L-carnitine plays a critical role in energy production, as it L carnitine supplement fat into energy. Those with low L-carnitine levels may benefit from taking an oral supplement, though. As well as supporting energy production, L-carnitine may help some other functions in the body, such as maintaining general brain function and reducing the risk of certain disorders.
Some people may experience mild side effects when increasing their L-carnitine intake, especially with long-term use.
In this article, we explore what the current research says about L-carnitine, including its benefits, effectiveness, and side effects. L-carnitine is a type of carnitinewhich is a derivative of amino acids. Amino acids combine to make proteins, which carry out many essential tasks in the body.
Carnitine helps the body break down fatty acids and turn them into energy to power the cells. L-carnitine is a conditionally essential nutrientmeaning that the body can generally make enough of it, but, in some cases, a person may have to get the compound from food or oral supplements if they cannot make enough.
In the body, the liver and kidneys create L-carnitine from the amino acids lysine and methionine. The kidneys can also store L-carnitine for later use and eliminate the excess through the urine stream. Carnitine is a broad term that describes a few different compounds.
L-carnitine is a more common form L carnitine supplement carnitine, present in the body and many supplements. Other forms of carnitine include:. L-carnitine, and carnitine in general, is a key component in creating energy for the cells. L-carnitine also has a secondary function of helping remove some waste products from the cells to prevent them from accumulating and causing problems.
In addition to its core functions, L-carnitine may also pose some other benefits to the body. These include:.
L-carnitine may help with some markers of heart health, although the research is still ongoing. Supplementation may help improve L-carnitine levels in a failing heart, which could boost heart health and circulation in the short term following a heart attack. Supplementation may also help with symptoms of heart failure, such as chest pain and arrhythmia. At times, cancer treatments, such as chemotherapy, may cause a person to become deficient in L-carnitine. In these cases, L-carnitine supplements may help reduce symptoms such as fatigue and weakness.
Researchers are currently studying the compound as a possible way to prevent tissue L carnitine supplement due to chemotherapy, but this research is in the early stages. As the kidneys and liver help create and use L-carnitine, disease in these organs or organ failure may lead to L-carnitine deficiency. Doctors may recommend L-carnitine supplementation in these cases to support the function of the kidneys and liver and prevent deficiency. Most people tolerate L-carnitine well.
However, some L carnitine supplement may experience digestive side effects when taking L-carnitine.
These include :. Some studies suggest that high levels of L-creatine may raise the long-term L carnitine supplement of cardiovascular diseases, such as atherosclerosis. L-carnitine supplements may interact with certain antibiotics or anticonvulsants. Anyone considering taking L-carnitine should talk to their doctor to discuss any medications they are taking and the possible drug interactions. The liver and kidneys will create enough to meet their daily needs. Even though the body produces it naturally, carnitine is widely available in a of simple foods. Animal proteins, such as fish, red meat, and poultry, are some of the best sources.
According to the NIHadults who eat a mixed diet that includes red meat and other animal products get about 60— milligrams mg of carnitine per day.
L-carnitine: benefits, side effects, sources and dosage
People who avoid animal products, such as those following a vegan diet, may get roughly 10—12 mg from their diet. The kidneys also eliminate excess carnitine through urine to maintain healthful concentrations. Generally speaking, otherwise healthy adults do not need to take L-carnitine to support their health. Some athletes take extra L-carnitine, believing that it will boost their athletic L carnitine supplement.
L-carnitine availability seems to limit muscle metabolism during very high intensity exercise. So, in theory, supplementing carnitine during workouts may support exercise performance.
However, a study in Molecules notes that the evidence for this practice is lacking. While many athletes take L-carnitine, years of research does not provide conclusive evidence to support these claims. As L-carnitine helps burn fatty acids for energy, many people assume that taking more of it may help them lose weight. More research is necessary, but some studies support this idea. In a review of nine different trials, researchers found L carnitine supplement evidence to support this claim.
They suggest that participants who took L-carnitine lost an average of 1. However, L-carnitine cannot replace healthful habits, such as a proper diet and regular exercise. People who wish to take L-carnitine should talk to a doctor first. The doctor may have additional recommendations to support any treatment that the person needs and can help them avoid possible reactions and interactions. The recommended dosage is roughly L carnitine supplement grams per day. However, people with genetic abnormalities or other conditions causing a lack of L-carnitine should talk to their doctor for a more specific dosage.
L-carnitine is an amino acid that the body naturally produces. In people with good health, the liver and kidneys produce and store enough of the compound to prevent deficiency. People with L-carnitine deficiencies may need to get the compound through their diet or as a supplement.
