In this blog post, we will look at why essential amino acids, which are important for protein synthesis and metabolism in the body, must be supplemented through food. Our bodies constantly repeat the process of synthesizing and breaking down proteins. Protein synthesis is the process of linking amino acids to form long chains, and about 20 amino acids are used for protein synthesis in the...
