The most common summation of amino acids, namely branched chain amino acids (BCAAs), that you’ll likely find online is that amino acids are the building blocks of protein. And while we won’t disagree with this statement, we’ll attempt to describe why some amino acid sports supplements might be worth taking, and, just as importantly, when to take them.
Amino acids are the building blocks of protein; proteins are the building blocks of life.
Everyone on the internet.
Objectively, a linear path from protein ingestion to muscle growth hasn’t been demonstrated. Many suspect that, alongside increased protein ingestion, insulin-like growth factors (IGF-x), testosterone and human growth hormone (H(GH)) stimulated by trauma to muscle fibres each play a role in muscle hypertrophy and adaptation to linearly progressing workloads.
And, the thinking goes, if muscles are comprised of proteins and ingested proteins are broken down into amino acids before they are re-built as proteins our bodies can use, then amino acid consumption will help to expedite the nutritional side of the muscle growth and repair equation.
