Whey Protein Amino Acid Profile

Although not vegan, I noticed it was a bit of pain to find a simple amino acid profile when researching similar for plant proteins. So I put together this page, plus it’s nice to compare whey to other protein sources.

The graph below was generated using our amino acid profile comparison tool, it shows a typical amino acid profile for whey. Essential amino acids have a little asterisk next to their names.

In case you prefer table form, here is the same data again:

  % of total amino acids
Alanine 5
Arginine 2.1
Aspartic Acid 11
Cystine 2.2
Glutamic Acid 18.1
Glycine 1.4
Histidine* 1.7
Isoleucine* 6.4
Leucine* 10.6
Lysine* 9.6
Methionine* 2.2
Phenylalanine* 3
Proline 5.5
Serine 4.6
Threonine* 6.7
Tryptophan* 1.4
Tyrosine 2.6
Valine* 5.9

Whey is essentially the gold standard when it comes to animal proteins, and proteins in general. It contains solid quantities of all the amino acids.
