Branched-chain amino acids (BCAAs) are among the oldest supplements taken by athletes and those wanting to increase muscle mass. These amino acids are the essential building blocks of protein and are required by the body to build and repair muscle. Pure BCAA powder from IronScience is designed to help stimulate protein synthesis, increase endurance, reduce muscle soreness and speed up recovery. The three main ingredients in pure BCAA powder from IronScience are leucine, isoleucine, and valine, which are among the nine essential amino acids required for life. Essential amino acids cannot be synthesised by the body on its own and must come from the diet, which is why for athletes and bodybuilders, essential amino acid supplements are a sure fire way of ensuring your body is getting enough.

Branched chain amino acids effects

The reason why BCAAs are so effective for building muscle tissue is due to the way they are metabolised. Most amino acids are metabolised in the liver. However, BCAAs are primarily metabolised in the muscle, allowing them to be used as energy by the muscle tissue. In addition, leucine, isoleucine, and valine are metabolised slightly differently. Leucine is broken down through the fat pathways, which helps reduce the amount of visceral fat in the body. Valine is broken down in carbohydrate pathways, while isoleucine is broken down in both. During exercise, there is a steep rise in the amount of this amino acid metabolism that takes place because the muscles require more energy.

BCAA benefits

During exercise, BCAAs provide energy for the muscles. If there is a deficiency, the body will resort to catabolising muscle tissue (turning muscle into energy), which is why ensuring your body has enough BCAAs during exercise is essential. Not only are BCAAs a source of energy for the muscles, but also they increase oxidation of fats, providing more energy and allowing you to work out for longer. Furthermore, a protein supplement such as pure BCAA powder increases protein synthesis, so after working out your muscles will recover quickly and produce enough replacement tissue to boost muscle mass.

Few protein powders can affect muscle growth and improve performance in the way BCAA pure powder from IronScience can. BCCA supplements can increase muscle growth, provide more energy during training, increase recovery times, reduce muscle soreness, prevent catabolism, boost immune function, and even reduce visceral fat. Therefore, if you are trying to increase muscle mass and are not yet taking BCAA powder from IronScience, you really should consider it.
