Amino Acid Profile

Amino Acid Profile


Which amino acids should I have in my diet?



We mentioned the categories of amino acids (AA) in our post about protein. Now we are going to breakdown specifically which amino acids fall into each category. This information will help you better determine which ones you should ensure are a part of your diet or should supplement! When buying protein powder or AA supplements, it’s crucial to determine the amino acid profile to see if it includes essential, conditional, or non-essential AA.

  • Essential AA (EAA)

    • Not made in body
    • Come from Diet & Supplementation
    • Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine
  • Conditional AA

    • Not sufficiently made in body
    • Mostly come from Diet & Supplementation
    • Arginine, Cysteine, Glutamine, Histidine, Proline, Taurine, Tyrosine
  • Non-essential AA

    • Sufficiently made in body
    • Diet & Supplementation not necessary
    • Alanine, Asparagine, Aspartic Acid, Citrulline, Glutamic Acid, Glycine, Serine

I know what you’re thinking, “How am I going to remember (or even pronounce) all of these amino acids & which category they fall in?” To be honest you won’t. But, we want you to be able to recognize their names when you see them, particularly the EAA. This recognition will help you determine which types of food or supplements to choose!
