Amino spiking is the practice of adding cheap free amino acids or other nitrogen-rich ingredients to a protein powder so its listed protein content looks higher.

**How we rank:** Amino spiking, also called protein spiking, happens when a manufacturer adds inexpensive amino acids such as glycine or taurine, or other nitrogen-rich ingredients such as creatine, to a protein powder. These ingredients raise the total protein figure on the label without adding much useful, complete protein.
