However, more research is needed to determine whether supplements provide any added benefits over a high protein diet. One possible complication is hepatic encephalopathy HE , which can lead to confusion, loss of consciousness and coma. A review suggests that in patients with liver disease, BCAA supplements may be more beneficial than other supplements at reducing the severity of HE Another review of studies in patients undergoing liver surgery reported that BCAA-enriched solutions may help improve liver function, reduce the risk of complications, and decrease the duration of hospital stay BCAA supplements may also be effective at reducing fatigue and improving weakness, sleep quality , and muscle cramps in individuals with liver disease In cases of liver cancer, taking BCAA supplements may help reduce water retention and decrease the risk of premature death However, if you have liver disease, please speak with your healthcare team about using BCAA supplements before starting them.

BCAA supplements may be effective at improving liver function and decreasing the risk of complications in individuals who have liver disease. Furthermore, there are no official recommended daily requirements for BCAA though there are studies that have suggested different amounts 44 , However, people who include sufficient protein-rich foods in their diets most likely do not need to take supplements.

Many people who are trying to gain muscle also take them in the morning and before bed. However, whether the exact timing makes a big difference for this has not been studied properly.

There is no official recommended dose for BCAAs, and since a diet that is sufficient in protein-rich foods may be all you need, you should speak with a healthcare professional before supplementing.

Adding foods from the list above to your diet will help you increase the amount of BCAAs you get each day. However, individuals with a rare congenital disorder called maple syrup urine disease should limit their intake of BCAAs because their bodies cannot break them down properly Taking BCAA supplements is generally safe, but BCAA supplementation is not recommended for some people.

Branched-chain amino acid supplements may provide impressive benefits in certain circumstances, especially when it comes to muscle growth and physical performance.

However, BCAAs can also be found in whole protein supplements as well as in a large variety of protein-rich foods.

Therefore, taking BCAA supplements may not be necessary, especially if you get sufficient amounts through your diet or a protein supplement. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

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. In this…. What is whey protein?

While some of these supplements actually deliver on their marketing, there are others that flat-out BCAAs shorthand for "branched-chain amino acids" are one of those workout supplements that, on first read, seem like they could help you improve your athletic performance and make greater gains in the gym, both in terms of mass and strengtth.

Amino acids, after all, are often referred to as the "building blocks" of muscle growth. And while that's true, you have to wonder if the amino acids found in BCCA supplements aren't a special kind of nutrient that you can't otherwise get from food sources.

So, if you want to build muscle and increase your strength, are you better off eating whole foods, protein powder, or even essential amino acid supplements EAAs, not to further complicate things?

Are BCAAs dangerous or do they have any side effects? And, maybe most importantly of all, do branched-chain amino acids even work? What Are BCAAs? These acids are molecules that form proteins within the body.

There are nine "essential" amino acids and a host of other non-essentials. If you want to get real geeky, Medline Plus has it all. BCAA supplements will often advertise those three aminos in conjunction with their muscle-building promises, and list the amount of each.
