Branched-Chain Amino Acids: Energy, Recovery, and Wellness
Branched-Chain Amino Acids (BCAA) are three of the nine amino acids our bodies can not make. BCAA consist of L-Leucine, L-Isoleucine, and L-Valine. These amino acids are found in foods and are used by our bodies to help make proteins. They may help with muscle growth, reduce muscle soreness and fatigue, and support liver health. Moreover, BCAAs are critical for skeletal muscle and constructive metabolism and energy balance. [https://pmc.ncbi.nlm.nih.gov/articles/PMC8329528/]
The Three Branched-Chain Amino Acids
Let’s take a quick look at the three amino acids that make up BCAAs and what they do for our bodies.
L-Leucine
Leucine plays a significant role in protein synthesis. It helps with metabolic functions. Leucine helps regulate blood sugar levels and growth hormone production. It assists with wound healing and the growth and repair of muscle and bone tissues. [https://pubchem.ncbi.nlm.nih.gov/compound/6106]
L-Isoleucine
Isoleucine also aids with regulation of blood sugar along with energy level. Its role is hemoglobin synthesis. Some functions Isoleucine helps with are wound healing and stimulating immune function. It’s known for helping in the rebuilding and repairing of muscles. Also, it helps the body recover after exercising. [https://pubchem.ncbi.nlm.nih.gov/compound/l-Isoleucine]
L-Valine
Valine encourages tissue repair and muscle growth. It supports mental vigor, muscle coordination, and emotional calm. [https://pubchem.ncbi.nlm.nih.gov/compound/6287]
Branched-Chain Amino Acids Benefits
BCCA particularly targets the body’s muscles. These three amino acids are mostly metabolized in the muscle tissue while other amino acids are metabolized in the liver. Some benefits of BCAA are they may help with muscle growth and ease soreness after exercising. They could help prevent muscle wasting, which is a sign of malnutrition. BCCAs may reduce the production of serotonin in the brain. This reduction could help reduce the fatigue you feel when exercising [https://www.healthline.com/nutrition/bcaa].
BCCA may have some involvement in regulating blood sugar. It may do this by preserving liver and muscle sugar stores. In turn, this stimulates your cells to take the sugar from the bloodstream. [https://www.healthline.com/nutrition/bcaa]
Branched-Chain Amino Acids may help with weight loss. There were a couple of studies with wrestlers and weightlifters. These studies showed taking a BCCA supplement over another supplement showed an increase in fat weight loss. More research needs to be done on this potential benefit, since there were some flaws in the studies. [https://www.healthline.com/nutrition/bcaa]
Where to get Branched-Chain Amino Acids
You can get your BCAA from things you eat. They’re found in meats, eggs, dairy, legume, seeds, and soy. Some meats to consider eating are poultry, salmon, and tuna. Eggs and milk are a good option too. Then there is tofu, quinoa, red lentils, hemp seeds, and peanuts. Check out this article from Runner’s World to read more details about the benefits of the above foods.
You can also get BCAAs from supplements. This is one way bodybuilders and athletes get more in their system. The supplement could help them with building muscles and recovery. Look for supplements that are naturally sweetened or at least low sugar. Also try to avoid artificial sweeteners, colors, and flavors.
Conclusion
The Branched-Chain Amino Acids, Leucine, Isoleucine, and Valine, are 3 of 9 essential amino acids our body needs and does not produce. They’re used to make muscle protein and energy. You can get them from foods you eat. There could be benefits with taking supplements if you exercise or are an athlete. They may help with muscle fatigue, soreness, and strengthen them.
