The modern sports nutrition market is represented by a wide variety of supplements, and often not only beginners, but also professional athletes find it difficult to decide which ones are more effective and give the best results, which ones to take for cutting, which ones during a diet, which ones will restore strength faster after intense exercise. Today, L-carnitine, a natural substance that plays an important role in energy metabolism, has become especially popular. It transports fatty acids inside cells to mitochondria, where they are burned and produced energy.

Who should take L-carnitine? Athletes who experience heavy loads during training and people on a diet. The supplement not only helps process fats already present in the body. It prevents the effects of new intakes from food, enriches cells with oxygen, normalizes the functioning of the liver, gastrointestinal tract, and thyroid gland, increases the effectiveness and quality of training, and reduces recovery time after training.

Rating of the best L carnitines

Is it possible to breed in advance?

If the drug is available in the form of special ampoules or powder, which is intended to be dissolved in water, then it is recommended to use the solution immediately after dilution. When choosing the most effective L-carnitine, it should be noted that any drug can also be diluted in protein shakes and amino acids, which are consumed throughout the workout. However, it is worth noting that in order to combat fat deposits, this method is ineffective, since it is only suitable for a constant supply of additional energy during aerobic and strength exercise.

Action of the substance

When L-carnitine enters the human body, it begins to attach to free fatty acids and also transfer them to muscle tissue, which at this time is under physical stress during various exercises.

When burning fat, energy is also released, which gives the athlete, or rather his muscles, more strength, both during aerobic and strength exercise. As a result of all this, L-carnitine works like an energy drink, helping a person to give more effort during strength exercises, and, like a fat burner, the drug can reduce the level of fat in the human body. When L-carnitine enters the body, it also increases sweating, which indicates that the metabolic process has begun, and the drug is working at this time.

Duration of the course

When considering which L-carnitine is best, it should be noted that taking the drug, regardless of the specific manufacturer, can be addictive. A constant high concentration of this substance in the body simply stops working, that is, it gets used to it, and the function of carnitine gradually becomes useless.

Therefore, experts recommend using the drug in cycles. Regardless of which L-carnitine is better, all manufacturers recommend using it for a month, after which a break is taken for the same period. Then the course is repeated. In addition, taking the substance is also allowed for two to three months in a row, but the break must be at least 1 month.

General description and purpose of application

L-carnitine, also often called levocarnitine, is a substance that is very similar in composition and effect to B vitamins. It is synthesized from amino acids, but is not considered an amino acid in itself. The main function of L-carnitine is to transport fatty acids, as well as to break down fats to release energy.

It is worth noting that each person’s body independently produces L-carnitine, but with its additional supply from sports supplements, fat metabolism begins to improve, and endurance and strength also increase. Beginners in sports and fitness quite often confuse this product with fat burners. Although this sports supplement really can fight extra pounds. The main task of the drug is to attach and transfer fat cells to mitochondria, where the process of fat breakdown begins, as well as to obtain energy in muscle tissue for better contraction.

Overnight appointment

In addition to pre-workout and morning doses, carnitine can also be taken before bed. In this case, the process of excretion and transport of fatty acids continues during sleep. It is best to take this method on rest days, but in this case the daily dose should be divided into two equal portions, the first of which is consumed on an empty stomach, and the other immediately before bedtime. Speaking about which l-carnitine is best to take before bed, preference should be given to dry forms, without sugar.
