Hemp Seed Protein 

Hemp seeds are second only to soybean in protein content. Proteins serve a variety of functions in the human body such as acting as enzymes, antibodies, and the structural components of tissues, hormones and blood protein. The main function of dietary protein is to supply amino acids for the growth and maintenance of body tissue. Digestion disassembles proteins into their basic building blocks - the amino acids. 

Hemp protein contains all 20 known amino acids including the 9 essential amino acids (EAAs) our bodies cannot produce. Proteins are considered complete when they contain all 9 essential amino acids in a sufficient quantity and ratio to meet the body's needs. Hemp seeds contain an adequate supply of these high quality proteins (EAAs) for a well balanced diet. 

Hemp protein is free of the tryspin inhibitors which block protein absorption and free of oligosaccharides found in soy, which cause stomach upset and gas. 

Approximately 65% of the protein in hemp seeds is made up of the globulin protein Edestin and is found only in hemp seed. Edestin aids digestion, is relatively phosphorus-free and considered the backbone of the cell's DNA. The other one third of hemp seed protein is Albumin, another high quality globulin protein similar to that found in egg whites.
