While some articles on this topic claim that hemp is complete, this is somewhat misleading. Hemp does contain all 9 essential amino acids, but amino acids Leucine and Lysine are at far lower levels than required. Hemp is, however, an excellent protein source with exceptional benefits and it can be blended with protein sources that are high in Leucine and Lysine, such as pea or soy protein powder. This provides a more complete protein while including the many additional benefits of hemp protein powder.
