Overall Summary of Brown Rice Protein’s Amino Acid Profile

Brown rice is almost a complete protein (a bit lacking in lysine as noted in a comment below). Pair it with legumes, which are high in lysine to round out your amino acid intake.

It contains all the essential amino acids, and its amino acids are well balanced, even more so than dairy milk.

There’s not much else to note!

Another comparable amino acid profile is spirulina, which is another great plant-based source of protein.
