While certain sugars and antibiotics are the mainstays of treatment for hepatic encephalopathy, BCAAs may also benefit people suffering from the disease 33 , 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 36 , Several studies have shown that taking BCAA supplements may offer protection against liver cancer in people with liver cirrhosis 38 , As such, scientific authorities recommend these supplements as a nutritional intervention for liver disease to prevent complications 40 , Summary 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 abundantly found in many foods and whole protein supplements.
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 43 :.
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.
Shop online for BCAA supplements. BCAA stands for branched-chain amino acids. These are essential amino acids with several benefits for muscle growth and performance. Though all 20 amino acids are vital for your health, only nine are classified as essential. However, research on these benefits is still limited, and results from existing studies are mixed.
There's no evidence that BCAA supplements are any more beneficial than getting these amino acids from your diet. Therefore, BCAA supplements may be best suited to those prone to nutritional deficiencies, such as vegans. World globe An icon of the world globe, indicating different international options.

Easier fat-loss, more energy and increased muscle gain are all benefits BCAA supplementation can make, but a well-rounded diet should be able to cover most of your muscle-building needs , without you having to turn to BCAA powder or BCAA tablets.
That's if you're not vegan or vegetarian, because many high-protein foods — think chicken, eggs and wild salmon — packing plenty of BCAA alongside the protein count.
Add these to your basket and stock up on strength. It's best to take BCAA supplements before a workout, up to 15 minutes pre-workout or taken during your workout to prevent further fatigue.
Broadly speaking, there's very little to be worried about when it comes to BCAA supplementation. Follow the instructions and be sure to take them at the right time. They won't make you overweight, either — a regular 10g serving of BCAAs contains approximately 40kcal.

Depending on what's in them, BCAA supplements can vary in calories, but ultimately do count towards your daily protein intake.
Some studies have been able to find some benefits. A study found that BCAA supplementation may decrease muscle soreness after exercise, but, when consumed alongside a diet of adequate protein, the results are "likely negligible".
In a study , participants reported reduced perceived exertion but they didn't actually improve their aerobic performance. A review of the literature on the subject ultimately concluded that "that the claim that consumption of dietary BCAAs stimulates muscle protein synthesis or produces an anabolic response in human subjects is unwarranted.
More to the point of practical BCAA supplement use, Leone states, "There is no evidence that amino acids that are taken in a form that is separate from food is superior to amino acids provided from eating food. Preliminary results appear to support the importance of BCAAs in your diet, but generally do not appear to support free form supplementation.
In all likelihood, BCAA supplements offer no benefit in those who are meeting their daily protein needs. Despite the lack of concrete evidence, Byron believes BCAA supplementation continues is this: "Because supplement companies take a bit of promising research and then hype it up, creating fear in the training population, and then it sells. Sales of BCAAs have diminished in the past two years as more research on them became available.
Leone adds that because elite athletes "are trying to squeeze out every potential performance advantage… [they] often use nutrition products that are deemed to be safe, but may have little to no benefit. In addition, many athletes have little to no understanding of how much BCAAs they are getting in their diet from the foods that they eat. That misunderstanding seems to be at the core of the issue — that more is better. But, as Leone explains, "Taking a supplement that provides BCAAs over and above what you get in your diet is unlikely to provide additional benefit, in much the same way putting more gas in your car than your gas tank can hold is not likely to improve your gas mileage.
How much protein is enough to know you're getting adequate amounts of amino acids? As a rough rule of thumb for calculating how much protein you need if you're an active individual, Byron suggests taking your body weight or what it would be if you have a target goal , and calculating 1 gram of protein per pound of body weight. So, so a pound individual would require a daily intake of grams of protein.
