Natural L-Leucine from Switzerland

The essential amino acid L-Leucine belongs, due to its structure, together with L-Isoleucine and L-Valine to the so-called branched chain amino acids. These are also called BCAA’s (Branched Chain Amino Acids). L-leucine and the other two BCAAs are popular among athletes because they help build muscle. Also, the BCAA’s are involved in the re-synthesis of all other proteins.


L-Leucine: The amino acid for muscles and muscle building

L-Leucine is an essential, protein-forming amino acids. It is found primarily in the muscles of humans and in the liver. It is a part of the BCAA (Branched Chain Amino Acids). The body cannot produce L-leucine itself. It must therefore be supplied to it externally via food or dietary supplements. L-leucine plays a large and central role in the energy balance of the muscles. It is particularly important for maintaining and building muscle tissue. It supports protobiosynthesis in the muscles and in the liver, i.e. it is jointly responsible for the important formation of new proteins. At the same time, it also inhibits the breakdown of muscle protein. In addition, L-leucine can also play an important role in muscle healing processes. The amino acid is thus particularly important in muscle building and in the healing of muscle injuries.

L-leucine is the most important amino acid in the body

L-leucine is one of eight essential amino acids that the human body cannot produce itself. Yet muscles, in particular, absolutely need this amino acid. For this reason alone, L-leucine is one of the most important amino acids for humans, if not the most important. Precisely because the body is not able to produce L-leucine itself to meet the need, it must be supplied with the daily diet. L-leucine is a component of both animal and plant proteins. For example, 100 grams of beef contain 1691 mg of L-leucine, and 100 grams of chicken breast fillet contain as much as 1732 mg. But plants and plant products can also have a high proportion of this amino acid. For example, 100 grams of walnuts contain 1170 mg of L-leucine and 100 grams of dried peas even contain 1760 mg.

L-leucine is of great importance for building muscle mass

For athletes and athletically active people, L-leucine has yet another special significance. For these people, as is well known, muscles play an even more important role. The amino acid promotes the building of muscle mass. As a rule, more muscles also mean greater performance and a lower risk of injury. This does not only apply to power sports, but to any form of sporting activity. By the way, a large muscle mass also prevents possible diabetes and increases metabolism. In other words, muscles are a true elixir of life for us humans.

Those who do not manage to take in enough L-leucine through their diet should turn to dietary supplements.

Normally, the required daily amount of L-leucine can be taken in through a balanced diet. However, those who do not manage to do so for whatever reason should turn to dietary supplements with L-leucine. We therefore offer you selected products in our online store that contain L-Leucine. These include especially “Amino Vida ” and “Amino Eight“, with which they can cover the entire needs of the body for essential amino acids. Just have a look around our store and browse through our rich offer. We sell only natural, scientifically tested dietary supplements. Quality and care are decisive factors for everything we do. Just have a look around. We are sure that you will find what you are looking for.
