PRO BCAA from Optimum Nutrition

Leucine, isoleucine, valine and glutamine are part of the Optimum Nutrition PRO BCAA amino acid complex. Unlike conventional BCAAs, the complex is reinforced with glutamine to support the athletes' immune system during active work on themselves. The brand has established itself both in professional sports and among amateurs. Amino acids are designed to block muscle catabolism on drying, and help recover from heavy mass training. The complex is suitable not only for bodybuilders, but also for power athletes, as well as ordinary fitness enthusiasts who want to maintain maximum muscle during weight loss.

The positive effects of the supplement are:

  • Maintaining lean muscle mass during calorie deficiency;
  • Muscle building in the mass-gaining period;
  • Maintaining energy metabolism during training;
  • Improving recovery processes after it;
  • Speeding up protein synthesis in muscle fibers;
  • Increases in strength indicators with optimal training;
  • Creating the conditions for high-quality fat burning

Of course, even the highest quality BCAAs will not work if the athlete trains without dedication and does not eat properly. Amino acid complexes are a quick fuel for training, and not a replacement for all not eaten portions of meat, and not drunk protein.


The supplement contains glutamine, leucine, isoleucine and valine. Calorie content - 5 kcal per 100 g. The composition also contains sodium, calcium, various flavorings and additives for taste. In one portion of 19 g, only 8 g of BCAA. For this, the manufacturer is criticized on the forums, as the attempt to "gain volume" with cheaper glutamine is regarded by many users as a hoax.

How to take PRO BCAA from Optimum Nutrition

The method of application depends on the goals of the athlete. The most common thing is to stir 2 scoops of the supplement in water and drink it before the workout. The second portion is usually “kneaded” and taken with you to drink during class, and during cardio after training. BCAAs are sometimes taken before bedtime to increase the secretion of growth hormone. Increased doses of glutamine are known to affect growth hormone. In bodybuilding practice, these are not the only ways to use. BCAA. Those who practice morning “hungry” cardio on drying can drink a serving of amino acids to protect their muscles from catabolism. Some strength training sources refer to increased effective dosages of BCAAs. This is 25 g per day of branched chain amino acids alone, excluding glutamine. Such dosages are needed for athletes who work purposefully according to the strength plan, striving for the development of muscle strength and mass. If we are talking about a girl, or a lightweight athlete engaged in fitness, the dosages can be considered overpriced. But there are no problems with excess BCAAs in the body, the human body simply removes excess amino acids. So the whole discussion rests only on the cost of the supplement.

BCAAs improve the performance of other sports nutrition supplements. For example, they can be taken with creatine or with nitrogen donors. But adding them to a protein shake is pointless. This does not allow the body to absorb amino acids from both protein and BCAA.

There is evidence that taking BCAA with L-carnitine improves the "percentage of fat burning", that is, allows you to get more energy from body fat, and not from the catabolism of muscle tissue.


This sports nutrition product collects positive reviews from professional athletes and amateurs. Many appreciate it for its taste. Natural BCAAs are known to have an unpleasant bitter-sour taste. Those athletes who are forced to take them without additives negatively assess their taste. But Optimum Nutrition's PRO BCAA contains state-of-the-art sweeteners and flavoring agents that change the taste of the product to a pleasant one. The most popular flavor from this brand is raspberry lemonade. Some people prefer to mix the tasteless supplement with juice, but this is an option for those who are not on the dryer.

Complaints about gastrointestinal upset, and improper functioning of the digestive system on forums and in open resources with reviews were not noticed. Sometimes they criticize the high price, but this is a property of quality brands of sports nutrition. The product is of high quality, and many of those who have tried it would buy it again.
