Glycomacropeptide is a type of protein. It is formed during the process of making cheese. Unlike many other proteins, glycomacropeptide contains only very small amounts of the amino acid phenylalanine.
People take glycomacropeptide for an inherited disorder that increases levels of phenylalanine in the blood (phenylketonuria or PKU), gout, obesity, and many other conditions, but there is no good scientific evidence to support these uses.
Is It Effective?
NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
- Gout. Early research shows that taking skim milk powder fortified with glycomacropeptide and a specific milk fat extract reduces gout flares. It might also reduce pain during a gout flare.
- Obesity. Replacing one or two meals per day with a supplement containing glycomacropeptide does not help to reduce weight more than taking a supplement with skim milk powder.
- An inherited disorder that increases levels of phenylalanine in the blood (phenylketonuria or PKU). Early research shows that replacing part of the daily dose of a regular phenylalanine-free protein supplement with glycomacropeptide maintains blood levels of the amino acid phenylalanine. In surveys, people with phenylketonuria seem to prefer supplements containing glycomacropeptide over regular phenylalanine-free protein supplements.
- Bipolar disorder.
- Dental cavities.
- Diabetes.
- Gout.
- Heart disease.
- Infant development.
- Liver disease.
- Other conditions.
More evidence is needed to rate the effectiveness of glycomacropeptide for these uses.
Is it Safe?
Glycomacropeptide contains very low levels of phenylalanine, which might make it a better protein source for people with phenylketonuria.
