There are 20 individual Amino Acids, they are called the building blocks of protein. Some of these are classed as 'Essential Amino Acids' (EAAs) which must be consumed in our diet for us to survive. The rest are classed as 'Non Essential Amino Acids' (NEAAs), these can be made by the body.
Recently key Amino Acids have gained attention for roles in metabolism, health, and body composition. Due to the fact that other nutrients may reduce or block their uptake, the best way to supplement Amino Acids is by using pure powders or capsules, rather than blended formulations.
