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.

BCAAs may also benefit people with liver disease. However, some research links increased BCAA levels to conditions such as diabetes , cancer, liver disease, and heart disease. People can use protein powder to supplement their protein intake, help build muscle, aid muscle recovery, and encourage healthy weight loss.

The findings, published in the International Journal of Sport Nutrition and Exercise Metabolism, shows how supplements with a mix of BCAAs and carbohydrates stimulated muscle building after weight-lifting exercises.

However, a treatment with all nine essential AAs will promote a muscle building response that is twice as strong as the BCAA supplements. Our results show that the common practice of taking combined BCAA plus CHO supplements will not result in maximal stimulation of muscle synthesis.

Instead, a sufficient amount of the full complement of amino acids is necessary for maximal stimulation of muscle protein synthesis following exercise.

Athletes interested in enhancing muscle growth with training should not rely on combined BCAA and carbohydrate supplements alone. With this combined research, the authors argue that BCAA supplements are not the best choice for weight training.

They recommend supplements with all the essential amino acids in their place and recommend athletes and gym-goers not rely exclusively on BCAA supplements.
