Camino Pro & GMP Story

GLYTACTIN is the world’s first PKU protein formula that is made from a natural whole protein.  This protein is called glycomacropeptide (GMP), is derived from whey and it is the only naturally occurring protein that does not contain phenylalanine (Phe) in its pure form. Given the natural absence of Phe, this unique protein makes it ideal for the PKU diet. GLYTACTIN was developed in collaboration with the University of Wisconsin and is a combination of GMP and certain critical amino acids, such as arginine and tyrosine, which are also not found naturally in GMP. Until the introduction of GLYTACTIN in 2010, PKU formulas were always made from 100% synthetic, man-made free amino acid proteins. Studies have shown that natural intact proteins, like GMP, have a slower absorption rate in the body and an improved protein usage when compared with single amino acids, which mimic whole intact protein.1
