The Bottom Line. Because essential amino acids cannot be synthesized within the body, they must be acquired from food. The function and shape of each protein varies depending on the number, type, and combination order of its amino acids.

All 20 amino acids are needed to build the body, but essential amino acids cannot be synthesized in the body and must be acquired from food.

If you consume BCAAs before exercising and use them as a source of energy, they will help you maintain your performance. Their main functions are as follows. The participants played simulated handball games over 2 consecutive days. The researchers found that intermittent sprint performance on the second day was significantly better in the athletes who had taken the supplement, compared with those who had taken the placebo. In a study , researchers randomly assigned participants with advanced liver cirrhosis into groups.

Doctors calculate MELD scores by measuring levels of certain substances in the blood, such as creatinine and bilirubin. They use the resulting score to help determine how close a person is to having liver failure.

The authors concluded that long-term BCAA supplementation has beneficial effects in people with advanced liver cirrhosis and that understanding these effects will require further research.

Another study from also found that BCCA supplementation improved low muscle strength among people with liver cirrhosis.

BCAAs are essential amino acids, which means that the body cannot make them. However, a wide variety of foods contain BCAAs, and most people can get enough by eating a protein-rich diet.

Also, many health and fitness stores sell BCAA supplements, and a person can purchase them online. There is no officially recommended BCAA dosage. Depending on the desired benefit, studies have used different dosages of these supplements.

However, anyone who experiences serious side effects should stop taking the supplement and consult their doctor. BCAAs are essential amino acids. The body cannot make them, so a person needs to get BCAAs from their diet or as supplements.

Research suggests that taking BCAA supplements may improve muscle mass and performance and may reduce muscle damage from exercise.
