Valine, isoleucine and leucine are called branched chain amino acids (BCAAs). They got this name due to their “branched” molecular structure. Researchers have found that such supplements can promote muscle protein synthesis, muscle growth, muscle recovery, and reduce muscle fatigue, especially after exercise.
BCAAs are the only amino acids that are metabolized primarily in skeletal muscle and to a much lesser extent in the liver. They can be considered as "fuel" for skeletal muscle. They are essential for the protein synthesis process and are capable of providing energy to muscles. All this makes BCAA irreplaceable assistants in preparation for the competition.
Additional beneficial properties of BCAAs include:
- Improving symptoms of insomnia and anxiety
- Appetite suppression
- Normalization of the immune system
- Participation in the restoration of muscle tissue
- Improving sports endurance
Natural sources include red meat, dairy products, legumes, nuts, cereals, and seeds.
The recommended dosage is approximately 5-20 grams per day, depending on its own weight and load.
