It is helpful in enhancing the performance, speed, weight loss, and other health benefits. Let us discuss the l carnitine usage pattern for various athletic benefit-.
Taking 3 grams mg l carnitine with fruit juice, about half an hour before practice can be beneficial for high intensity running performance. Taking about 1. If you are thinking that like many other supplements, is is required to cycle l carnitine; then the answer is no.
It is not at all required to load l carnitine supplement. The recommended dosage can be uniformly followed throughout the period you are supplementing yourself with it. For some, 1 gram mg of l carnitine could be sufficient while some may require higher dose of upto 4 gram mg each day. There are several variants of l carnitine is available for different purposes and health benefits like acetyl l carnitine, l carnitine l tartrate, propionyl l carnitine, etc. Among these, l carnitine l tartrate is considered most effective for athletic performances.
However, the total dose can be split up in smaller doses, and can be taken after each of the meals during the day. If you are looking for l carnitine weight loss dosage, one of the strategies could be taking a dose of l carnitine l tartrate as a post workout supplement and taking 2 to 3 dose of acetyl l carnitine in between the meals.
L carnitine can be taken with other fat burning supplements. 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 number of simple foods. Animal proteins, such as fish, red meat, and poultry, are some of the best sources. According to the NIH , adults who eat a mixed diet that includes red meat and other animal products get about 60— milligrams mg of carnitine per day. 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 performance.
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 some 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 1—3 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.
It is advisable to talk to a doctor before taking an L-carnitine supplement. Some people may wish to take L-carnitine supplements for their potential benefits, such as aiding athletic performance or weight loss. However, more research is necessary to confirm these benefits.
Carnitine occurs in almost every cell in the body and in most foods. It may help treat a range of health conditions. This toxicity may also occur following acute valproic acid overdose. L-carnitine administration may help treat valproic acid toxicity in children and adults, though the optimal regimen has not been identified [ ]. L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine are available over-the-counter as dietary supplements. Carnitine is often promoted as an aid for weight loss, to improve exercise performance, and to enhance a sense of well-being [ 2 ].
It is also a drug approved by the Food and Drug Administration to treat primary and certain secondary carnitine-deficiency syndromes. The federal government's — Dietary Guidelines for Americans notes that "Because foods provide an array of nutrients and other components that have benefits for health, nutritional needs should be met primarily through foods.
In some cases, fortified foods and dietary supplements are useful when it is not possible otherwise to meet needs for one or more nutrients e. For more information about building a healthy dietary pattern, refer to the Dietary Guidelines for Americans and the U.
