BCAAs and muscle building -
At age 62, "Big Bill" shares his wisdom to dominate one of the ultimate strength marks. Follow these fit women we're crushing on for inspiration, workout ideas, and motivation.
And how you pair supps can also increase or decrease their potency, like combining stacks of creatine and beta-alanine increases their muscle-building properties or mixing calcium and iron together creates competition among them for absorption by the body, limiting their efficacy.
Branched chain amino acids, or BCAAs , are leucine, isoleucine, and valine, and they are used to increase muscle mass and battle fatigue, but a new study published in Frontiers in Physiology has found that they may not work so well on their own.
For the small study, researchers put 10 trained lifters through experiments where they downed a BCAA drink 5. In that case, the muscle synthesis response doubled. Athletes interested in enhancing muscle growth with training should not rely on these BCAA supplements alone.

Read article. There are 20 different amino acids that make up the thousands of different proteins in the human body. Nine of the 20 are considered essential amino acids , meaning they cannot be made by your body and must be obtained through your diet.
Of the nine essential amino acids, three are considered branched-chain amino acids BCAAs : leucine , isoleucine, and valine. They are also a popular dietary supplement sold primarily in powder form. The BCAA leucine activates a certain pathway in the body that stimulates muscle protein synthesis, which is the process of making muscle 1.
In one study, people who consumed a drink with 5. Whey protein contains all of the essential amino acids needed to build muscle. BCAAs play an important role in building muscle.
However, your muscles require all of the essential amino acids for the best results. This soreness is called delayed onset muscle soreness DOMS , which develops 12 to 24 hours after exercise and can last up to 72 hours 7. Meanwhile, other research suggests that it may actually be related to the connective tissue associated with the muscle rather than the actual muscle itself 8.
BCAAs have been shown to decrease muscle damage, which may help reduce the length and severity of DOMS. Several studies show that BCAAs decrease protein breakdown during exercise and decrease levels of creatine kinase, which is an indicator of muscle damage 9 , In one study, people who supplemented with BCAAs before a squat exercise experienced reduced DOMS and muscle fatigue compared to the placebo group Therefore, supplementing with BCAAs, especially before exercise, may speed up recovery time Just as BCAAs may help decrease muscle soreness from exercise, they may also help reduce exercise-induced fatigue.
Everyone experiences fatigue and exhaustion from exercise at some point. How quickly you tire depends on several factors, including exercise intensity and duration, environmental conditions, and your nutrition and fitness level Your muscles use BCAAs during exercise, causing levels in your blood to decrease.
When blood levels of BCAAs decline, levels of the essential amino acid tryptophan in your brain increase In your brain, tryptophan is converted to serotonin , a brain chemical that is thought to contribute to the development of fatigue during exercise 14 , In two studies, participants who supplemented with BCAAs experienced a reduction in central fatigue, resulting in improved athletic performance 16 , BCAAs can alter levels of certain chemicals in the brain, such as serotonin, which may be useful in decreasing exercise-induced fatigue.
Muscle proteins are constantly broken down and rebuilt synthesized. The balance between muscle protein breakdown and synthesis determines the amount of protein in muscle Muscle wasting is a sign of malnutrition and occurs with chronic infections, cancer, periods of fasting , and as a natural part of the aging process 19 , Several studies support the use of BCAA supplements for inhibiting muscle protein breakdown.
This may improve health outcomes and quality of living in certain populations, such as older adults and those with conditions like cancer 23 , Taking BCAA supplements can prevent the breakdown of protein in certain populations with muscle wasting.
BCAAs may offer health benefits for people with cirrhosis, a chronic disease in which the liver does not function properly. While certain sugars and antibiotics are the mainstays of treatment for hepatic encephalopathy, BCAAs may also benefit people with this condition One review of 16 studies including people with hepatic encephalopathy found that taking BCAA supplements had a beneficial effect on the symptoms and signs of the disease, but had no effect on mortality Liver cirrhosis is also a major risk factor for the development of hepatocellular carcinoma, the most common form of liver cancer, for which BCAA supplements may also be useful 28 , 29 , Several older studies have shown that taking BCAA supplements may offer protection against liver cancer in people with liver cirrhosis 31 , As such, scientific authorities recommend these supplements as a nutritional intervention for liver disease to prevent complications BCAA supplements may improve the health outcomes of people with liver disease, while also possibly protecting against liver cancer.
BCAAs are found in foods and whole protein supplements. Getting BCAAs from complete protein sources is more beneficial, as they contain all the essential amino acids.
Fortunately, BCAAs are available in a variety of food sources. This makes BCAA supplements unnecessary for most, especially if you consume enough protein in your diet already 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.
Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. BCAA stands for branched-chain amino acids.

While some Weight management solutions 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.BCAAs and muscle building -
The most critical time to get a gram dose of BCAAs is before workouts. The reason is that BCAAs are unlike any other amino acids. They don't need to go to the liver first; they can go directly to the muscle cells, where they're used for fuel. The next most critical time to take grams of BCAAs is after workouts.
Here, it's important to get leucine to the muscle cells, where it can activate the protein kinase mTOR and push muscle protein synthesis as well as muscle growth. When you eat a meal that includes at least 3 grams of leucine and at least 30 grams of protein, muscle protein synthesis is spiked momentarily.
About two hours after the meal, protein synthesis will have dropped, but the amino acids from the meal are still in the bloodstream. At this time, if you provide another 3 grams of leucine as well as the other two BCAAs , it may create a second spike in muscle protein synthesis from that same meal.
As mentioned, you need at least 30 grams of a complete protein, as well as a good 3 grams of leucine, to maximize muscle protein synthesis. If a meal provides less than 30 grams of protein, it likely also doesn't provide a full 3 grams of leucine.
To create a bigger spike in protein synthesis from this meal, you can take a gram dose of BCAAs to ensure that the leucine content is high enough to do it. Each serving of Pre JYM and Post JYM active matrix provides 6 grams of BCAAs in the proper ratio of leucine to isoleucine to valine.
That means you can take either product depending on your caffeine tolerance and needs to get your BCAAs, along with additional ingredients like creatine, beta-alanine, betaine, taurine, and glutamine Post JYM only.
If you want to save those products just for pre-workout and post-workout, you can also use a stand-alone BCAA product—like my brand-new JYM BCAAs product , available exclusively here at Bodybuilding.
JYM BCAAs includes the ideal ratio of leucine to isoleucine to valine. For more articles on nutrition and supplementation, as well as workouts and training tips, visit JimStoppani.

The Best Time to Take BCAAs to See Results. Jim Stoppani, Ph. Sponsored By:. About the Author. One group took a BCAA supplement and the other a placebo. The team then asked the participants to cycle to exhaustion. The researchers found that during the cycling, blood levels of serotonin were lower in the participants who took BCAA.
Serotonin is an important brain chemical that also plays a role in exercise fatigue. BCAA supplementation also improved energy metabolism and lowered levels of substances that indicate muscle damage, such as creatine kinase and lactate dehydrogenase.
According to the authors of a study from , BCAA supplementation can also help improve lean mass and decrease the percentage of body fat. The study involved 36 strength-trained males who had practiced resistance training for at least 2 years.
The participants underwent an 8-week resistance-training program, and the researchers randomly assigned them to groups. Each received either:. The researchers found that the participants who took BCAAs had a more significant decrease in body fat and a greater increase in lean mass, compared with the other groups.
According to a review , a variety of illnesses can affect protein synthesis, which can lead to a loss of body protein and skeletal muscle mass. The authors found evidence that a high-protein diet that provides additional leucine can help maintain muscle mass in people with chronic diseases such as cancer.
A systematic review found some evidence that BCAA supplementation can help reduce the muscle damage that occurs during high-intensity exercise. However, the authors caution that the evidence base was limited to one small study and that confirming these findings will require more research.
Results of a small study from show that adult male participants who took a BCAA supplement during exercise had lower blood levels of substances that indicate muscle damage than those who took a placebo.
The researchers concluded that BCAA supplementation may reduce muscle damage after endurance exercises. A study investigated the effects of combined BCAA and arginine supplementation on intermittent sprint performance over 2 consecutive days.
Arginine is another type of amino acid. The study involved 7 females and 15 males who had competed at a national or international level in handball. The participants played simulated handball games over 2 consecutive days.
The researchers found that intermittent sprint performance on the second day was significantly better in the athletes who had taken the supplement, compared with those who had taken the placebo. In a study , researchers randomly assigned participants with advanced liver cirrhosis into groups.
For at least 6 months, each group consumed either BCAAs daily or a diet without BCAAs. Over 2 years, Model for End-Stage Liver Disease MELD test scores improved significantly among participants who consumed BCAAs, compared with those who did not.
Doctors calculate MELD scores by measuring levels of certain substances in the blood, such as creatinine and bilirubin. They use the resulting score to help determine how close a person is to having liver failure.
The authors concluded that long-term BCAA supplementation has beneficial effects in people with advanced liver cirrhosis and that understanding these effects will require further research. 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.
