Key Takeaways
BCAA is an acronym for one of the most frequently used dietary supplements in bodybuilding and endurance sports. Every athlete, regardless of their training level, wonders whether to include BCAA in their diet. In this article, I will explain what BCAA stands for, what its composition is, and what benefits it can offer.

Amalgamation of three branched-chain amino acids: leucine, valine, and isoleucine

This combination consists of three branched-chain amino acids: leucine, valine, and isoleucine. BCAA is thought by manufacturers to support muscle growth and inhibit muscle tissue breakdown. In studies on the effectiveness of BCAA, dosages from 3 to 20 g were used. In practice, dosages of 7 to 20 g are most commonly used, so it is assumed that 10 g BCAA per day is the optimal dose. It is also important to note that in most popular products, about 0.8 g of pure amino acids correspond to 1 g of product. 2. Why do we use BCAA, and what is the dosage of BCAA? It is thought that BCAA branches support muscle growth, but it's also very difficult to inhibit muscle protein breakdown without them. In studies on the effectiveness of BCAA, dosages from 3 to 20 g were used. In practice, dosages of 7 to 20 g are most commonly used, so it is assumed that 10 g BCAA per day is the optimal dose. It is also important to note that in most popular products, about 0.8 g of pure amino acids correspond to 1 g of product. 3. Do we even need to supplement BCAA? The answer to this question depends on whether we are professional athletes or amateurs. Why? Because professional bodybuilders can benefit from BCAA supplementation, but amateurs who care about their figure can also use it. Catabolism is a process in which our body consumes itself, gaining energy from combustion. It has been proven that catabolism is a manifestation of cannibalism of our body, but it only occurs after about 72 hours of physical activity, when we eliminate all sources of plant and animal protein for this time. Since this happens so late, how can it affect us in half an hour before we return home and eat? The answer is: it doesn't. Because we don't have a large muscle mass with a fat content of only a few percent and a huge energy expenditure, like professional bodybuilders. 4. Summary We already know what BCAA is and who can benefit from BCAA supplementation. If you have a large budget, you can take advantage of the benefits of BCAA. In good protein sources such as whey isolate or concentrate, the same amino acids are contained, but at a lower price – therefore, good protein sources should also be considered under the aspect of a high BCAA content.
