Glycomacropeptide is a type of short protein. It is formed from a milk protein during the process of making cheese. Unlike most other proteins, glycomacropeptide contains very little of the amino acid phenylalanine.
People take glycomacropeptide for heart disease, preventing dental cavities, gout, infant development, liver disease, phenylketonuria, mental conditions, and weight loss.
How does work?
Glycomacropeptide might help improve weight loss by increasing the release of chemicals that make people feel full. Glycomacropeptide might also attach to certain bacteria, viruses, and toxins and prevent them from infecting people.
Insufficient Evidence to Rate Effectiveness for...
- Phenylketonuria. Early research suggests that replacing a typical phenylalanine-free diet with foods enriched in glycomacropeptide maintains blood levels of the amino acid phenylalanine and does not negatively affect health and kidney function in people with phenylketonuria. But compared to a typical phenylalanine-free diet, people with phenylketonuria prefer to eat foods enriched in glycomacropeptide.
- Weight loss. Clinical research suggests that replacing one or two meals daily with a meal-replacement supplement containing glycomacropeptide for one year while also following an energy restricted diet reduces weight by approximately 24 lbs compared to baseline. However, the effect of the glycomacropeptide supplement does not appear to be different than taking a similar skim milk powder supplement.
- Heart disease.
- Dental cavities.
- Gout.
- Infant development.
- Liver disease.
- Mental conditions.
- Other conditions.

SLIDESHOW
Vitamin D Deficiency: How Much Vitamin D Is Enough? See SlideshowGlycomacropeptide is POSSIBLY SAFE when taken by mouth as a food supplement for up to one year.
Pregnancy and breast-feeding: Not enough is known about the use of glycomacropeptide during pregnancy and breast-feeding. Stay on the safe side and avoid use.Children: Glycomacropeptide is POSSIBLY SAFE when added to formula and given to infants. However, there is some concern that formula containing glycomacropeptide might increase the risk of blood threonine levels becoming too high (hyperthreoninemia).
The appropriate dose of glycomacropeptide depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for glycomacropeptide. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
