Are human protein powders complete?

Asked October 8, 2013, 8:33 PM EDT

What is the position on the use of protein powders, particularly PureLean? My daughter-in-law has been using this product and they seem to be odd veggie proteins, and in no way complete. My feeling is that she needs the amino acids found in animal proteins and that she needs to have at least a serving day of those. Thanks.

As a rule, the majority of Americans consume adequate protein and meet the RDA of 0.8 gm/kg body weight so protein powders are not needed by most. Some that might need a protein supplement include those with impaired food intake, undergoing cancer therapy or other medical conditions. Upon examination of the PureLean product PureProtein Plus, the ingredients providing the protein include whey protein, soy protein isolate, milk protein concentrate, whey protein isolate, whey protein isolate. Whey protein is a component of milk protein. Soy protein is one of the highest quality plant proteins. There is high quality protein in this supplement coming from both animal (milk) and plant (soy) origins. The amino acid profile also includes all of the essential amino acids.
