Benefits of branched-chain amino acids -

That has two important implications for performance:. BCAAs have been found to inhibit the onset of both central and peripheral fatigue during exercise, so you can go stronger for longer.

Peripheral fatigue when your muscles get tired is delayed because BCAAs are used as an additional energy source during prolonged exercise. Central fatigue when your brain gets tired may also be delayed by BCAAs that block the amino acid tryptophan from getting into the brain.

As any athlete knows, a a small increase in performance can mean the difference between a podium finish…or not. Importantly, the results of these studies indicate that BCAA supplementation can improve both aerobic exercise capacity and anaerobic performance!

Intense, high volume training repeated over days and weeks can lead to fatigue, immune suppression, and overtraining if an athlete does not recover adequately between training bouts. Chronic long term supplementation with 12g BCAA daily has been shown to improve the immune response to several weeks of intense endurance training in cyclists Kephart et al.

But how? Researchers have found that BCAAs can also be used by immune cells within the gut as a fuel source, which allows the immune system to regenerate itself more efficiently and protect against harmful pathogens Zhang et al, A strong immune system aids in recovery and makes you less likely to get sick.

During exercise, muscle protein breakdown, and in particular, BCAA breakdown for energy is increased Shimomura et al. By providing supplemental BCAAs, the body is less likely to consume its own amino acid protein stores.

Think of them as your muscle insurance policy! This is probably the number 1 reason weight lifters love BCAAs! As mentioned before, leucine is the most important of the three BCAAs for initiating muscle protein synthesis MPS , which is necessary for muscle building.

As a point of reference, one large egg contains about 0. BCAA administration prior to and following exercise may reduce the severity and duration of delayed onset muscle soreness DOMS , the painful sensation that lasts for several days after an intense or unaccustomed exercise bout Shimomura et al.

Furthermore, studies have shown that BCAA intake reduces muscle damage in response to both resistance training Howatson et al. That means you can bounce back faster and have less muscle soreness between challenging workouts.

The exact dosage and ratio of leucine:isoleucine:valine is still a matter of debate in the literature, but most studies supplemented within a range of g BCAAs per day, usually split into multiple doses.

Make it a habit — studies observe benefits after a week or more of supplementation. Favorable results have been seen with prolonged use, as it appears that the enzyme activity necessary to break down BCAAs increases in response to habitual intake.

Many studies have observed benefits after a week or more of daily supplementation. Use anytime — before, during, and after workouts. BCAAs can be taken before, during, and after workouts to rapidly increase amino acid levels in the bloodstream, promote protein synthesis, and prevent muscle protein breakdown.

They may also be taken between meals if you feel your diet is not providing adequate levels of BCAAs in the form of complete protein from meat, dairy, fish, eggs, etc. Supplemental BCAAs are sold encapsulated like our ROCTANE BCAA Capsules , or in plain or flavored powder form, that can be mixed into liquid.

BCAAs are beneficial for athletes, individuals engaged in high volume or prolonged exercise, those on restrictive diets who many not get enough from whole food sources, or for anyone otherwise at risk of lean tissue breakdown.

Research has shown supplemental BCAA intake to be safe for healthy adults in doses of g per day, with prolonged intake one week or more showing greater benefits than acute short term intake.

Consuming protein-rich foods will also provide you with other important nutrients that BCAA supplements lack. The best food sources of BCAAs include 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 :. Many protein-rich foods contain high amounts of BCAAs.

If you consume enough protein in your diet, BCAA supplements are unlikely to provide additional benefits. The branched-chain amino acids BCAAs are a group of three essential amino acids: leucine, isoleucine, and valine. BCAA supplements have been shown to build muscle, decrease muscle fatigue , and alleviate muscle soreness.

They have also successfully been used in a hospital setting to prevent or slow muscle loss and to improve symptoms of liver disease. However, because most people get plenty of BCAAs through their diet, supplementing with BCAA is unlikely to provide additional benefits.

But what are BCAAs and what are the benefits of taking a BCAA powder supplement? How do they work and should you be taking them? Grenade nutritionist Alex Beaumont gives us the lowdown on this popular supplement. Amino acids are the building blocks of protein.

There are 20 amino acids that make up the proteins found in our bodies and in the food we eat. This means that somehow, we need to get the other nine essential amino acids through our diet.

Of these nine, there are three that make up BCAAs Branched Chain Amino Acids. BCAAs, are three essential amino acids that are particularly important for our muscles.

The three, leucine, isoleucine, and valine, are common in foods such as red meat and milk. They can also be supplemented through powder, such as whey protein, or capsules. The other six are also important and these can be sourced by having a varied diet with a focus on high protein sources.

The main benefit of BCAAs is their positive effects on your muscles. It has been suggested that BCAAs, especially leucine, can increase muscle protein synthesis the process your body goes through when it builds muscle mass when paired with resistance training. This means that supplementing with BCAAs will help to turn on the muscle-building engine and increase your gains after a tough session at the gym.
