BCAAs have also been associated with muscle growth due to one particular amino acid: leucine. This may help to explain why a review found BCAA supplements with a higher proportion of leucine may improve body composition by increasing muscle mass.
However, researchers concluded that the "methodology and quality of studies were too varied to draw any firm conclusion. According to Fawkes, BCAAs increase muscle mass, and the more muscle you have, the more calories you burn due to an increased metabolic rate. However, researchers provided no information about the participants' diets, which could have impacted the outcomes.

One particular complication of liver disease that BCAAs are believed to alleviate is hepatic encephalopathy HE , a deterioration of brain function that can cause confusion and loss of consciousness.
Additionally, a meta-analysis found BCAAs improved liver function and reduced the severity of HE as well as the duration of the hospital stay for patients undergoing liver surgery. However, another review of nine studies indicated BCAAs did not lower the risk of other complications like gastric bleeding or improve the overall survival rate.
Experts agree that most people do not need to take BCAAs as long as they maintain a well-rounded diet. However, those on a strictly plant-based diet may benefit from taking BCAAs.
Ayesta suggests finding a supplement containing all nine essential amino acids instead of just BCAAs. According to Fawkes, there's limited research on the optimal time to take BCAAs — some opt to incorporate them into a pre-workout regimen to fuel their performance, while others prefer to take them after in hopes of supporting muscle recovery.
However, one small study found men who took a BCAA supplement before an arm strength exercise experienced less muscle soreness and lower blood markers of muscle damage after the exercise was over than those who took the supplement after. BCAAs may support weight loss and muscle growth while reducing fatigue, muscle soreness, and complications of liver disease. When taken as instructed and at the correct times, BCAAs won't make you gain weight either a common concern and a regular question in the MH inbox , as a regular 10g serving of BCAAs contains approximately 40kcal.
