Branched Chain Amino Acids (BCAA) have once again come into the vogue in bodybuilding and fitness communities after a series of research results that list the advantages of BCAA supplements.

Amino acids can be used to maintain mass in athletes, without requiring them to stick to a calorie-rich diet. Unsurprisingly, many bodybuilding competitors are latching onto BCAA supplements to lean their physique to the extreme, without pressing their digestive system.

Supplements are preferable to dieting because they do not affect your looks on the beach and performance in bed.

Dieting nips at your muscles

Dieting is often touted as a good way to become lean; very few individuals are aware of the negative consequences of eating less-than-adequate food. The body starts consuming fat. It makes one think that he or she is losing weight. But this process does not last for long. As one marches ahead and continues to diet, the self-preserving brain springs into action--saving fat, so that it can last longer, and nipping away at muscles. The muscle-destroying biochemical reactions increase in intensity until the person returns to normal eating.

Best BCAA supplements increase your muscle mass

Amino acids for weight loss have two advantages over BCAA supplements: (a) they stimulate protein synthesis by activating those biochemical reactions that contribute to the creation of proteins. (b) Amino acids reduce the rate of breakdown of proteins. In other words, BCAA supplements boost your muscle mass and reduce muscle loss.

And this is not the end of the list of BCAA benefits--more positive advantages include the inhibition of serotonin.

Serotonin is a chemical. It is made from tryptophan. When a person works out, tryptophan reaches into the brain where it changes into serotonin--a chemical that produces a sense of fatigue. We do not need to explain that a powerful feeling of tiredness kills the appetite for exercise.

Amino acids inhibit serotonin from reacting with neurotransmitters in the brain--thereby, allowing athletes to work out until the time they need.
