What is L-carnitine?

L-carnitine is an amine synthesised from two essential amino acids, lysine and methionine. L-carnitine performs important functions in the human body, essentially the reception and transport of fatty acids to the inside of the mitochondria located within the cells.

L-carnitine transports fatty acids to the cells, where this fat is burnt which produces energy for the organism.

In short, L-carnitine burns fat and enhances physical performance, helps to increase energy, improves the absorption of oxygen and the protein metabolism.

Therefore, it is vital for physical exercise since it encourages performance, reduces tiredness and helps the body to recover sooner after physical or mental effort.

Due to its properties, L-carnitine supplements are one of the most widely used products in sports nutrition.

How does L-carnitine work?

L-carnitine performs essential functions, similar to the ones of vitamins, and it is involved in numerous metabolic processes in the body.

Firstly, it promotes the detoxification of organic waste through the kidneys and liver. Moreover, it transforms long-chain fatty acids into energy. This is essential for the functioning of different organs, and specially for the heart.

In all of its tasks, L-carnitine acts as a biocarrier, leading fatty acids to the mitochondrial membranes where they are transformed into energy.

Whenever the body needs to produce energy, L-carnitine comes into play by helping to burn fat in order to make energy available for the body.

In short, L-carnitine provides energy and strength, it increases physical performance in active people and helps with weight loss. It also promotes the optimal functioning of the metabolism of fat, stimulates the mind and protects the nervous system.

Properties and benefits of L-carnitine

L-carnitine burns body fat

L-carnitine is involved in the burning of lipids and in controlling fat metabolism, which helps to reduce body fat significantly. Due to this, it becomes an indispensable supply for people who are slightly overweight and who want to reduce body fat and lose weight.

L-carnitine helps to lose weight in a healthy way

People who are following a diet run the risk of suffering an L-carnitine deficiency. This is usually due to the fact that they avoid eating meat in order to consume less calories. It is necessary to resort to L-carnitine dietary supplements to compensate for this deficiency.

An L-carnitine deficiency causes fatigue and exhaustion. In order to avoid this, it is recommended to consume at least one gram of an L-carnitine dietary supplement daily.

In addition, L-carnitine reduces sudden drops of glucose in the blood, which diminishes the feeling of hunger and craving for food, which will help us follow the diet more easily and to lose weight more quickly.

L-carnitine, the most effective supplement in sports nutrition

L-carnitine has numerous properties and benefits, specially for those who do exercise and high-intensity sports: bodybuilding, aerobics, fitness and weightlifting, among others.

L-carnitine increases energy, strength, and power, while providing a greater endurance to fatigue and pain. L-carnitine improves the absorption of oxygen and helps to build muscle mass.

The latest clinical studies on this topic have proven that the muscles recover faster after exercise when using L-carnitine, which allows a more intense training and an easier recovery. 

L-carnitine is a product that not only improves performance in those who do exercise and muscle training, but it also favors muscle mass building and helps to maintain it in perfect condition for longer.

Those who do exercise and intensive sports training should add L-carnitine supplements to their diet, since it helps to reduce the pain and tiredness after hard workout sessions. This product also facilitates recovery after exercise and physical effort, and helps to destroy unwanted fat deposits.

L-carnitine promotes the optimal functioning of the immune system

L-carnitine contributes to keeping the immune system in a proper state, since it can make pathogens become harmless. At the same time, it stimulates the formation of defenses, which blocks the development of diseases.

L-carnitine also acts as an antioxidant element, which prevents free radicals from destroying the cells and tissues.

L-carnitine specially protects the membranes and nerve cells and prevents the degradation of neurons, which results in the prevention of degenerative neurological diseases such as Alzheimer's or Parkinson's disease.

L-carnitine protects against diabetes

The main struggle of diabetes patients in most of cases is fending off the effects of oxidative stress. According to clinical studies carried out in 2008, and confirmed in 2016, L-carnitine dietary supplements reduce LDL cholesterol and triglycerides levels and reduce the effects of oxidative stress.

L-carnitine reduces the appearance of heart diseases

L - carnitine produces around 70% of the energy that the heart needs to function. For this reason it supports the heart of those who are suffering from certain diseases, such as angina or coronary atherosclerosis, and prevents possible heart attacks. On the other hand, dielectric L-carnitine supplements also avoid the development of arrhythmias and reduce the severity of congestive heart failure.

The benefits of L-carnitine to fight cancer

In 2012, the University of Greifswald found a surprising benefit of L-carnitine in order to fight advanced pancreatic cancer. Patients with pancreatic cancer suffer a dangerous weight loss. Clinical studies proved that by taking L-carnitine dietary supplements, this weight loss is considerably reduced.

L-carnitine benefits for old people

One of the most important benefits of L-carnitine for old people consists on reducing fatigue and tiredness by stimulating a vitality while also improving mood.

Natural sources of L-carnitine

L-carnitine is mainly found in the muscle tissue of animals.

Red meat contains large amounts of this nutrient, especially lamb, venison, followed by cattle and deer meat. On the contrary, chicken, turkey, and pork have a low amount of L-carnitine.

People who do not like meat may alternatively consume seafood, lobster and oysters, which are great sources of L-carnitine, as well as eels and herring.

For vegetarians, it is harder to find this nutrient in natural sources. The best choice, in this case, is eating dairy products, especially cheese, goat cheese, cottage cheese, and condensed milk. In the case of vegans, their only natural source of L-carnitine is fresh mushrooms.

Another fact to keep in mind is that only between 54% to 87% of the carnitine content in food can be used efficiently by the body.

L-carnitine supplements

It is very difficult to meet the requirements of L-carnitine that the body needs only through natural sources.

In order to avoid an L-carnitine deficiency in the organism, the most comfortable and practical solution consists on consuming a dietary supplement of this product every day.

In regard to this aspect, it should be pointed out that even though L-carnitine comes naturally from meat, the dietary supplement is obtained through a fermentation process, so that vegetarians and vegans can take it with peace of mind, allowing them to take full advantage of the multiple benefits of this substance.

L-carnitine dietary supplements products are available in capsules, liquid and powder. In liquid and powder form they can be comfortably diluted in water or juice, while capsules are easier to carry around.

L-carnitine intake

As with all dietary supplements, it is important to consume the correct amount of product.

In general, the maximum daily intake should not exceed 2000 mg, divided into several servings (at least two). On the other hand, most of the clinical studies conducted in 2016 showed that even with smaller intakes one can already begin to notice the effects.

Those who eat little meat and who are frequently tired, should consume a maximum of 500 mg L-carnitine daily. Those who suffer from obesity and who want to lose weight should consume around 1.000 mg. In any case, one should read the recommended daily intake that comes with each product and follow the instructions.

Side effects of L-carnitine

L-carnitine is an endogenous substance that the body assimilates very well and which is completely safe, even when consumed in extremely high doses. If we follow the amount indicated in the product's instructions, no side effects will occur.

Only in the case of consuming more than 5 grams per day we may experience some discomfort, such as diarrhea, dehydration, nausea, increased body temperature, or difficulty to sleep. However, these effects disappear immediately after reducing the intake.
