Overall Summary of Pea Protein’s Amino Acid Profile

Pea protein has a great amino acid profile, that’s why it’s the most popular protein source in vegan protein powders.

First of all it is a complete protein, meaning that it has a significant amount of all the essential amino acids

We can compare it to whey protein’s amino acid profile to see how they stack up. They’re pretty similar except for a few differences. Pea protein is relatively:

  • High in arginine
  • High in glycine
  • High in phenylalanine
  • Low in threonine
  • Slightly low in leucine*, isoleucine*, and lysine*

Peas are lower in those 3 essential amino acids, but if you look at the chart or table, you can see that it’s by a very small amount. Pea protein is very comparable to whey protein’s amino acid profile when you look at the overall amino acid profile.
