Who would guess that amino acids are the main building blocks for your muscle tissue?! Yes indeed! This is why they are so important in your healthy lifestyle. Whether you want to lose weight or gain muscles Amino Acids are the number one supplements you should think about first. The most important amino acid is glutamine which is the building block for your muscle. If you are planning to lose weight then it is a must for you to take glutamine and BCAA’s to prevent muscle loss. Otherwise, most of the weight you lose will be from your muscles instead of fat. In a case when you are a hard gainer then the most important amino acid for you would be Arginine with glutamine.
