L-carnitine (also known as levocarnitine) is an amino acid structure produced naturally by the body. It can be taken as an oral supplement or taken from the diet. L-carnitine is a key ingredient in energy production. It converts fat to energy.
Most people can get enough L-carnitine through their diets or from their bodies’ production. However, those with low levels of L-carnitine may be able to benefit from an oral supplement.
L-carnitine can support energy production as well as other functions. It may also help maintain general brain function and reduce the risk of developing certain diseases.
There are some mild side effects that may occur when L-carnitine intake is increased, particularly if it is long-term.
This article examines the latest research on L-carnitine. It includes its benefits, effectiveness and side effects.
L-carnitine, a type carnitine that is a derivative amino acids, is one form of carnitine. Proteins are formed when amino acids and proteins combine. These proteins carry out many of the essential functions in the body. Carnitine is a substance that helps the body to break down fatty acid and convert it into energy for the cells.
L-carnitine, which is a conditionally important nutrient, can be made up to 80% of the body’s needs. However, some people may need to take oral or food supplements if they are unable to make enough.
L-carnitine is made in the body by the liver and kidneys from the amino acids methionine and lysine. L-carnitine can also be stored in the kidneys for later use, and excreted through the urine stream.
Carnitine can be described as a variety of compounds. L-carnitine, which is more commonly found in the body and many of its supplements, is another form of carnitine. You can also find carnitine in the following forms:
* Acetyl L-carnitine: This type, also known as ALCAR (alcohol and carnitine), plays an important role in metabolism. It may have neuroprotective properties, which can help protect the nervous systems.
* D-carnitine (mirror image of L-carnitine): It can cause harm to the body by blocking the absorption of other forms carnitine.
* L-carnitine L.tartrate: This type of supplement is often used by athletes. It may help reduce muscle soreness and speed up recovery, according to research.
* Propionyl-L-carnitine: This form displays pain relieving and antirheumatic properties, and it may benefit heart health.
L-carnitine and carnitine are key components in creating energy for cells. Its primary function is to break down fatty acid for energy. This keeps cells powered up and running efficiently.
L-carnitine has the secondary function of helping to remove certain waste products from cells, which helps prevent them from accumulating.
L-carnitine is not only good for its core functions but may also have other health benefits. These are:
Heart health
L-carnitine could help with certain markers of heart health. However, research is still ongoing.
Supplementation can help increase L-carnitine levels in failing hearts, which can boost circulation and heart health in the short-term after a heart attack. Supplementation can also be used to treat symptoms such as arrhythmia and chest pain.
Treatment for cancer
Sometimes, chemotherapy or other cancer treatments can cause an individual to be deficient in L-carnitine. L-carnitine supplements can be helpful in these situations to reduce fatigue and weakness.
The compound is being studied by researchers as a way to protect tissue from chemotherapy. However, this research is still in its early stages.
Liver or kidney disease
L-carnitine deficiency can occur when the liver and kidneys are not working properly. L-carnitine supplementation may be recommended by doctors in these situations to maintain the function of the liver and kidneys, and prevent deficiency.
L-carnitine is well tolerated by most people. Some people may experience side effects from L-carnitine. These side effects include:
* stomach cramps
* nausea
* vomiting
* diarrhea
People may experience a fishy body odor. Although not usually dangerous, it can be irritating.
Studies have shown that L-creatine levels high in excess may increase the risk of developing cardiovascular disease, such as atherosclerosis.
L-carnitine supplements can interact with anticonvulsants and antibiotics. Talk to your doctor if you are considering L-carnitine. Discuss any medication and possible drug interactions.
It is possible to get the best L-carnitine depending on your reasons for wanting it.
A healthy adult is one who has a good general health.
According to the National Institutes of Health, healthy people don’t need additional L-carnitine supplements or food. Their daily needs will be met by their liver and kidneys.
Carnitine can be found in many simple foods, even though it is naturally produced by the body. Some of the most important sources are animal proteins like fish, red meat and poultry.
The NIH estimates that adults who eat a mix diet including red meat and other animal products consume 60-180 mg (mg) of carnitine each day. Vegans and people who do not eat animal products may receive between 10-12 mg.
The kidneys can store carnitine so that people have similar levels regardless of what they eat. To maintain healthy levels of carnitine, the kidneys remove excess through urine.
L-carnitine is not necessary to support health in healthy adults.
Athletes
A few athletes believe that extra L-carnitine will help them perform better in the gym. L-carnitine availability appears to limit muscle metabolism when exercising at high intensity. Theoretically, supplementing with carnitine while exercising may help improve performance.
A study published in Molecules found that there is no evidence to support this practice. Although many athletes consume L-carnitine, research over years has not provided conclusive evidence.
For weight loss
Many people believe that L-carnitine can help reduce weight by burning fatty acids. Although more research is needed, some studies support this notion.
Researchers found evidence supporting this claim in a review of nine trials. Researchers found that L-carnitine users lost on average 1.3 kg (2.9 pounds) less than those who didn’t take it.
L-carnitine can’t replace healthy habits like regular exercise and a proper diet.
Talk to your doctor before you take L-carnitine. A doctor might have additional suggestions to help the patient and may be able to help avoid reactions or interactions.
L-carnitine is well tolerated by most people. L-carnitine should be taken in small amounts, approximately 1-3 grams daily. People with certain conditions or genetic abnormalities that cause a deficiency in L-carnitine need to consult their doctor.
L-carnitine, an amino acid the body naturally produces, is one such example. The liver and kidneys of healthy people produce enough L-carnitine to keep them from becoming deficient.
L-carnitine deficiency patients may require the compound as a supplement or in their diet. Before taking L-carnitine supplements, it is best to consult a doctor.
L-carnitine supplements may be a good option for some people, including those who are looking to improve their athletic performance and weight loss. These benefits are not yet confirmed by research.
