Natural L-Isoleucine from Switzerland

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

L-isoleucine

L-isoleucine belongs to the group of essential amino acids. This means that the human body cannot produce this amino acid itself. Therefore, L-isoleucine must be ingested with food. L-isoleucine has many functions in the human body. This amino acid is known for its abilities to help blood clot in wounds and to help repair muscle tissue. L-isoleucine also helps increase energy levels and improve physical endurance.

For these reasons, L-isoleucine is popular among endurance athletes and bodybuilders as a dietary supplement. The amino acid provides an extra boost of energy and helps the body recover faster after periods of strenuous physical activity.

What is L-isoleucine?

Similar to leucine and valine, isoleucine also belongs to the branched-chain amino acids (BCAA). These active ingredients support physical training and muscle recovery. In the body, L-isoleucine is broken down in muscle tissue. Left-handed refers to the spatial arrangement of the molecule. The amino acid helps regulate blood sugar levels and stabilize energy levels. In doing so, it increases the body’s ability to utilize glucose during exercise. However, L-isoleucine does not promote the synthesis of glycogen.

People with low levels of this essential amino acid experience symptoms similar to those of hypoglycemia (low blood sugar). These may include headaches, fatigue, dizziness, irritability or depression. However, people who eat a balanced diet are rarely deficient in this amino acid.

Natural sources of L-isoleucine

Protein-rich foods are usually rich in essential amino acids. We can find them in fish, meat, legumes, eggs or nuts. The following foods are a good source of L-isoleucine.

Chickpeas
Kidney beans
Soybeans
Rice bran
Corn
Hemp seed
Chia seeds
Brazil nuts, hazelnuts, almonds, peanuts
Kale, spinach
millet, oat flakes, oat bran

The benefits of L-isoleucine

Endurance athletes in particular take this amino acid as a dietary supplement. Amino acids help the body cells to function optimally. L-isoleucine also helps remove nitrogenous waste such as ammonia from the body through urinary excretion. This improves wound healing and enhances the absorption of glucose as an energy source. When L-isoleucine is taken as a dietary supplement, it should be used in combination with leucine and valine for best results.

Another advantage of this amino acid is support for muscle recovery, for example, after an intense workout. L-isoleucine promotes anabolic response and reduces the rate of protein breakdown. This in turn helps to increase athletic performance.

L-isoleucine is important for the regulation of blood sugar levels, a deficiency of this active ingredient can be reflected in hypoglycemia. Regular intake of branched-chain amino acids can improve mood and mental performance.

L-isoleucine supplements are easy to take and offer many benefits. Improved protein and muscle synthesis and glucose uptake are just a few. If you’re looking for an extra workout edge or to promote better muscle repair in your body, supplements like Amino Vida or Amino Eight may be right for you.

Side effects of L-Isoleucine

For healthy adults, taking the amino acid in normal doses is considered safe. Like any dietary supplement, L-isoleucine can cause side effects. People who should contact their doctor before taking it include:

People with heavy alcohol consumption
Pregnant or breastfeeding women
People with ALS
People who are waiting for surgery
People with liver or kidney problems

However, excessive consumption of this amino acid (especially from supplements) can lead to excessive urination, liver disease, and depression. Replacing carbohydrates with protein can lead to serious nutritional imbalances, as complex carbohydrates such as whole grains, beans and potatoes are packed with vitamins, fiber, minerals and other plant-based nutrients.

Any questions?

People with an acute or pre-existing medical condition should talk to their doctor before taking amino acid supplements. We are also available to answer any additional questions you may have. If you are interested in L-Leucine, you can find more information, for example, in the Amino Vida and Amino Eight preparations.
