Drugstore articles: L-Leucin Video Guide

L-Leucine is a so-called essential amino acid that supports muscle build-up, among other things. L-Leucine supports the protein biosynthesis in the muscles as well as in the liver. It thus inhibits the overall breakdown of muscle proteins. In practice, L-leucine often serves as a dietary supplement for strength athletes. As an essential amino acid, L-leucine must be taken up by humans with food, especially as the human body is not able to produce L-leucine by itself. In addition, L-leucine is one of the three branched-chain amino acids that occur alongside isoleicin and valine. L-leucine is therefore also referred to as BCAA. This abbreviation stands for the English term branched-chain amino acid, which means nothing else than branched-chain amino acid.

In contrast to the other essential amino acids, the BCAAs mentioned above are exclusively degraded in the muscle cells. For this reason, the three BCAAs are virtually predestined to prevent muscle breakdown during the individual training units during weight training. Especially L-Leucine stands out from the other BCAAs. Because of its mode of action, L-leucine is best suited to build muscle mass in addition to inhibiting the breakdown of muscle tissue. Two further properties of L-leucine should be emphasized: the promotion of fat burning and the optimization of insulin sensitivity. As an amino acid that supports protein biosynthesis in the muscles as well as in the liver, L-leucine helps to build protein in muscle tissue and in the liver. In this respect, L-leucine also protects against liver damage, in particular against the damaging effect of alcohol. Due to its fat burning effect, L-Leucine is also frequently used during a diet. Ultimately, L-leucine has a regulating effect on the blood sugar level. L-leucine promotes the release of insulin. In addition to the regulating effect on the blood sugar level described above, this increased insulin sensitivity leads to an acceleration of the absorption of this amino acid in muscle tissue. This also has a positive effect on muscle growth; moreover, L-leucine counteracts the production of the stress hormone cortisol. Overall, the mode of action of L-leucine can be further described to the effect that it regulates the body’s own fat and muscle proportions by supporting the release of free fatty acids. L-Leucine also has a considerable weight because of its healing supporting effect in case of diseases of the joints and diseases of the liver and muscle tissue. Last but not least, this essential amino acid supports the release of the growth hormone somatotropin. For this reason, L-Leucine is also taken by adolescents. By supporting the release of somatropin, L-Leucine has positive effects during the human growth phase, in particular by having a beneficial effect on the formation of organs.

The required requirement of L-leucine is 1.2 grams per day. This daily requirement is regularly and easily covered by a balanced diet. In this respect, the consumption of rice, beef, salmon and other wholemeal products is recommended, as these foods contain a fairly high proportion of L-leucine. An increased intake of L-leucine through dietary supplements is only indicated in the case of illness or higher sporting stress on the muscles, such as during strength training or bodybuilding. For example, there are pure L-Leucine tablets on the market that promote the build-up and regeneration of lean muscle mass. Here it is among other things the highly effective L-Leucin tablets from gonutrition, German Elite and for example from Nutri-Plus, which occur quite frequently in the trade. Powder can also be used instead of tablets. To be mentioned here, for example, is the 750 grams of pure leucine powder from Pharmasports. It is important to follow the respective dosing instructions. An overdose regularly leads to nausea and vomiting as well as abdominal pain. Otherwise, L-Leucine is very well digestible as a food supplement.
