Amino acids are the building blocks of proteins and are the core of every cellular process. There are 23 amino acids, but our bodies don't produce all of them. Those we can't produce are known as 'essential amino acids,' without which the body's proteins degrade, affecting muscles, connective tissue, organs, nails, and hair. So, how does one make sure they have the amino acids they need? A healthy diet is the first step. But as we all know, we don't get the complete range of nutrients needed from diet alone. This is why supplementation can be helpful to ensure healthy intake of amino acids.
