One way they may do so is by lowering blood levels of the enzymes creatine kinase and lactate dehydrogenase, which are involved in muscle damage.

This may improve recovery and provide some protection against muscle damage Various studies asked participants to rate their muscle soreness levels after performing certain strength-training exercises.

However, effects may vary based on your gender or the total protein content of your diet 19 , BCAAs taken before or after strength training may reduce muscle soreness following your workout. However, the effects may vary from one person to another.

After all, research shows that BCAAs do activate enzymes responsible for building muscle Some studies also show that BCAA supplements may be effective at increasing muscle mass, especially if they contain a higher proportion of leucine than isoleucine and valine 25 , In fact, studies show that taking supplements with whole protein may, at least in some cases, be better for muscle growth than taking supplements with individual amino acids Getting enough BCAAs may boost muscle growth.

You can get them from high protein foods in your diet or through supplements. Leucine and isoleucine are thought to increase insulin secretion and cause your muscles to take in more sugar from your blood, thereby decreasing your blood sugar levels 28 , However, in practice, not all studies back up these effects 30 , In fact, some even report potential rises in blood sugar levels, depending on the type of diet participants followed.

For instance, when BCAAs are combined with a high fat diet, consuming them in supplement form may lead to insulin resistance 32 , That said, many of these studies were done on animals or cells, which means that their results may not be totally applicable to humans.

For example, in one recent study participants with liver disease were given In 10 participants, blood sugar levels were reduced, while 17 participants experienced no effects BCAAs may help promote blood sugar management, at least in some cases.

However, more studies are needed to confirm their effects. Competitive wrestlers consuming a high protein, calorie-restricted diet supplemented with BCAAs lost 3.

The BCAA group also lost 0. The BCAA group also gained 4. That said, these two studies have some flaws. For instance, they provide little information about the composition of the supplement and of the diet followed, which could have influenced the outcomes.

BCAAs may help prevent weight gain and enhance weight loss. 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.

While fasting has become a popular weight-loss strategy in recent years, some people worry that it will lead to muscle loss. However, research suggests that this doesn't have to be the case. In fact, one study found that taking branched-chain amino acids BCAAs while fasting actually helped to preserve muscle mass.

BCAAs are a type of amino acid that is often taken as a supplement to help with muscle building and recovery. When taken while fasting, they can help to prevent the breakdown of muscle tissue. Additionally, BCAAs can help to reduce feelings of hunger, making it easier to stick to your fast.

So if you're looking for a way to maintain your muscle mass while fasting, consider taking BCAAs. So, what are BCAAs and why should you be taking them?

BCAA stands for branched chain amino acids. These are the essential building blocks of protein that help preserve muscle mass during fasting or dieting. Taking BCAAs while fasting can help offset any muscle loss that may occur, keeping your body looking lean and toned.

So, if amino acid supplementation can help you build more muscle, it can potentially boost weight loss. The key here may be to supplement with BCAAs, or branched-chain amino acids. Of the nine essential amino acids, three have a structure with branched chains: isoleucine, leucine, and valine.

Leucine may be the most important of them all in terms of muscle growth. There is evidence that these three amino acids play a bigger role in muscle building than the others, which is why BCAA supplements have become so popular in the weight room.

Studies have shown that these amino acids may improve muscle development by activating certain enzymes after a workout.

Researchers have also shown that BCAAs can help you maintain muscle mass even while restricting your diet.

Somatotropin, or STH, is a growth hormone that the body produces mostly at night, during sleep. It stimulates the building of protein from amino acids and the oxidation of fat. One way to burn fat and lose weight is to have more of this growth hormone.

But you can't just get a supplement or injection of it. What you may be able to do is supplement with the amino acids that stimulate the secretion of STH. The essential amino acid methionine, and the non-essential amino acids arginine and glutamine, may be able to do this and promote weight loss.

There is some evidence that taking these amino acid supplements on an empty stomach before bed can increase STH secretion and fat loss. There may be another reason to supplement with glutamine for greater weight loss. Glutamine can actually be converted to glucose, the sugar that provides the body's main source of energy, and do so without impacting the hormones that stimulate fat storage.

This means that glutamine can provide energy without pushing the body to store extra energy as fat. It may also reduce sugar cravings for some of the foods that tend to make us fat in the first place, as well as alcohol. Other glutamine benefits may include helping with gut health and immune functions when the body is stressed.

L-glutamine is the most common amino acid in your body. It benefits the immune system and helps with protein synthesis.

For this reason, bodybuilders used to use glutamine supplementation to help with building muscle mass and muscle recovery. However, using glutamine supplements for this purpose has since been proven ineffective.

Some weight loss clinics promote lipotropic injections along with diet and exercise as a way to promote fat burning and weight loss. The lipotropes used typically include a mix of amino acids, minerals, and vitamins, such as the following:. While a lipotropic injection is not regulated like a typical prescription drug, it is best to talk with your doctor before trying them.

The effectiveness of these weight loss injections has not been proven. Excessive amounts of some ingredients may impact the effectiveness of other drugs and can cause side effects, such as fatigue, constipation, diarrhea, increased heart rate and more.

The evidence supporting the role of BCAAs in muscle development is strong, and this is already a popular supplement with weightlifters. But there is also proof that these three amino acids alone are not enough. What you really need to build muscle to support weight loss is all of the nine essential amino acids.

A study from supplemented participants with BCAA or a placebo after strength training workouts. The researchers concluded that BCAA supplementation does improve muscle growth, but that it has a limit. The better way to maximize gains in muscle tissue after working out, according to this study, is to supplement with all of the essential amino acids, not just BCAAs.

A better choice, if you want to supplement with amino acids, is to find a product that includes all the EAAs, not just the BCAAs. There may be some added benefit to choosing an EAA supplement that includes extra BCAAs, especially leucine. There may not be many significant risks to increasing your amino acid consumption via a BCAA supplement, but there still can be some side effects.

Consider these side effects of amino acid supplementation 6 :. As if weight loss research and advice weren't already confusing, now there is new evidence showing that a diet that restricts BCAAs may actually improve weight loss. Researchers at the University of Wisconsin found that a diet lower in BCAAs improved symptoms in patients with metabolic syndrome, a condition that includes high blood sugar, high cholesterol, and excessive abdominal fat.

The diet with fewer BCAAs helped patients get leaner and regulate blood sugar. Conclusions: BCAA supplementation does not preserve lean mass or affect insulin sensitivity in overweight and obese adults during weight loss. A higher protein diet may be more advantageous for lean mass preservation.

Published by Oxford University Press on behalf of the American Society for Nutrition. Abstract Background: Branched-chain amino acid BCAA supplementation has been shown to increase muscle mass or prevent muscle loss during weight loss.

So, in a fasted state, your body will not use muscle tissue for fuel which is ideal for those using BCAAs for cutting fat while maintaining muscle. This is particularly important when your glycogen stores are empty 4. Isoleucine also has a muscle building and sparing effect, it's not nearly as effective as leucine.

Its secondary function involves increasing glucose uptake into the muscles during exercise 5. It would be beneficial, however, during a lifting session after a meal to increase available energy.

Valine is a bit more of a mystery — it appears to be weaker than both other amino acids for stimulating muscle growth and preventing catabolism 6. From the start, anybody who is in a calorie surplus or is trying to gain weight can take BCAAs, but you guys should hit the shakes as well.

If you're a hardgainer needing some help, then check out this introduction to a hardgainer's diet. For those looking to maintain their physique, it's down to your diet. If you consume enough protein on a daily basis and can maintain your strength and size, there is no need to supplement with BCAAs.

If you begin eating at maintenance and your strength or size start to go down, BCAAs could prevent muscle loss. Along with a high-protein diet, BCAAs can be an important addition to a cutting routine to prevent as much catabolism as possible. BCAAs for cutting and losing weight is best taken during times of fasting.

This is when some BCAA pills or a shake would be a beneficial bridge until your next meal or workout. The normal ratio of BCAAs are usually of leucine, Isoleucine and Valine respectively.

Recently more combinations have come out such as or , but they have yet to be tested as extensively. A dose of four grams leucine, two grams Isoleucine and Valine is the usual serving size for those using BCAAs for cutting and will keep you going for hours.

Pure leucine powder may be a better option for some, since it gives you nothing but leucine. It's an effective amino acid for dieting and usually has no fillers. You can have this on its own or add it to your existing supplements to increase the leucine content.

There are also the derivatives of leucine. Scientifically known as? The other metabolite of leucine — HMB — has been more extensively researched. It's shown to be extremely effective at preventing muscle catabolism.
