L-carnitine, sometimes called levocarnitine, is the body’s amino acid compound. Because it transforms fat into energy, L-carnitine is an essential cog in the wheel of energy generation. Whether consumed or synthesized by the body, most people will receive enough L-carnitine levels.
However, an oral supplement may help those whose L-carnitine levels are low.
Along with aiding energy synthesis, L-carnitine may assist other bodily processes, such as lowering the risk of certain diseases and preserving overall brain function.
While taking more L-carnitine, some people may feel a little queasy, particularly after using it for a while.
Learn about the advantages and efficacy of L-carnitine based on what the latest research offers in this article.
Physiological Function
L-carnitine primarily aids in energy generation and mitochondrial activity in the body.
When present in cells, it facilitates the transfer of fatty acids to the energy-producing mitochondria.
Although your liver, kidneys, blood, and heart all contain minute quantities of L-carnitine, your muscles retain most of it (almost 95%).
Mitochondrial activity is essential in both illness and healthy aging, and L-carnitine may aid in increasing this function.
Modern studies show that various types of carnitine may help with various medical issues, including neurological disorders and cardiac ailments.
Potential advantages:
The process of cells generating energy relies on L-carnitine and carnitine more generally. The body’s cells are fueled and functioning correctly by their primary purpose, which is to aid in the breakdown of fatty acids for energy utilization.
A secondary role of L-carnitine is to remove certain waste products from cells, thus preventing their accumulation and subsequent malfunction.
In addition to its role in the body, L-carnitine may have other positive effects. Some examples are:
-
Cardiac wellness
Studies on the effects of L-carnitine on various heart health indicators are in their early stages.
A failing heart’s L-carnitine levels may be improved by supplementation, enhancing circulation and heart function in the immediate aftermath of a heart attack.
Chest discomfort and arrhythmia, two indications of heart failure, may also find relief with supplements.
-
Cancer therapy
A lack of L-carnitine can occur in some cancer patients as a side effect of chemotherapy and other therapies. Supplemental L-carnitine may alleviate symptoms like weakness and exhaustion in these individuals.
The chemical is presently the subject of a preliminary investigation into its potential to mitigate tissue damage caused by chemotherapy.
-
Illness of the kidneys or liver
A lack of L-carnitine can occur if the kidneys or liver are ill or if these organs fail to produce enough L-carnitine. In such circumstances, doctors may suggest taking L-carnitine supplements to help the liver and kidneys work properly and avoid deficiencies.
When and how to administer
Who needs extra L-carnitine, and why can dictate the optimal dosage and type of this chemical?
-
People with good overall health
People who are already in good health do not require more L-carnitine, according to the NIH. The kidneys and liver will produce enough to satisfy their daily requirements.
Despite being a naturally occurring substance in the body, carnitine is easily accessible in many common meals. One of the greatest ways to get protein is to consume seafood, red meat, and chicken.
The National Institutes of Health report that persons whose diets contain a variety of meats and other animal products typically consume 60-180 milligrams (mg) of carnitine daily.
Vegans and anyone who chooses not to consume animal products in their diet may acquire 10–12 milligrams daily.
Carnitine levels in the body are mostly unaffected by dietary changes since the kidneys can store them for later use. To keep concentrations healthy, the kidneys also excrete extra carnitine in urine.
In most cases, persons with good health don’t require L-carnitine supplements.
-
Sportsmen
A few sportsmen supplement their diets with L-carnitine, hoping it will improve their performance.
During extremely high-intensity exercise, the availability of L-carnitine appears to restrict muscle metabolism. In principle, using carnitine supplements while exercising might help you perform better.
There is a dearth of evidence for this approach, according to research on Molecules. Despite the widespread use of L-carnitine among athletes, the results of the many studies that have looked into the supplement have not been definitive.
-
To reduce body fat
Many believe increasing their L-carnitine intake can aid in weight loss since it promotes the burning of fatty acids for energy. Several studies provide credence to this notion, although further investigation is required.
Researchers discovered evidence to support this assertion in a meta-analysis of nine experiments. Individuals who supplemented with Lcarnitine shed an additional 1.3 kg (2.9 lb) compared to those who did not.
On the other hand, Lcarnitine isn’t a substitute for healthy lifestyle choices like eating well and exercising regularly.
Recommended dosage
Consult a medical professional before taking L-carnitine. In addition to providing the patient with the therapy they require, the doctor may also offer suggestions to assist them in minimizing side effects and drug interactions.
Tolerance to L-carnitine is generally good. Daily dosing should be between one and three grams.
A more precise dosage should be discussed with a doctor by those who suffer from genetic defects or other disorders that lead to an L-carnitine deficiency.
In the end!
The human body generates L-carnitine, an amino acid, on its own. A healthy person’s liver and kidneys make and store enough of the chemical to avoid a shortage.
Those who don’t receive enough L-carnitine in their diets may have to take a supplement. Before using an L-carnitine supplement, it is recommended to see a doctor.
Due to its possible advantages, such as weight reduction or athletic performance, some people may choose to use L-carnitine supplements. Nevertheless, further studies are needed to validate these advantages.
