Whey Protein Amino Acid Profile

W

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.

(Data Source)

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

 % of total amino acids
Alanine5
Arginine2.1
Aspartic Acid11
Cystine2.2
Glutamic Acid18.1
Glycine1.4
Histidine*1.7
Isoleucine*6.4
Leucine*10.6
Lysine*9.6
Methionine*2.2
Phenylalanine*3
Proline5.5
Serine4.6
Threonine*6.7
Tryptophan*1.4
Tyrosine2.6
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.

Note that it’s more balanced overall than the amino acid profile of milk, with relatively higher levels of cystine and tryptophan.

  • Do you know what the beef (filet mignon) amino acid profile is? I crave beef more than anything. What am I missing? I do not crave chicken. Eggs don’t cut it. Whey comes closer but still misses. What does beef have more or better than the other proteins? Thanks.

    • It’s likely the flavor more than anything, not a specific amino acid.

      Try cooking an alternative and flavor it like you would have with beef.
