Quorn protein ‘twice as effective’ for building muscle

    3 July 2019

    A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building more effectively than milk protein.

    The study evaluated the digestion of protein, which allows amino acids (the building blocks of protein) to increase in the bloodstream and then become available for muscle protein building in 20 healthy, trained young men at rest and following a bout of strenuous resistance exercise.

    The young men performed the exercise and were then given either milk protein or mycoprotein. Their muscle building rates were then measured in the hours following protein consumption.

    Animal proteins like milk are an excellent source for muscle growth, so they provide a useful comparison for testing other protein sources.

    The results showed that while those who ingested milk protein increased their muscle building rates by up to 60 per cent, those who had mycoprotein increased their muscle growth rates by more than double this – showing that mycoprotein, the main ingredient in all Quorn products, is a more effective source of protein to promote muscle growth.

    Dr Benjamin Wall, the study’s lead author, said: “These results are very encouraging when we consider the desire of some individuals to choose non-animal derived sources of protein to support muscle mass maintenance or adaptations with training.”

    “Our data show that mycoprotein can stimulate muscles to grow faster in the hours following exercise compared with a typical animal comparator protein (milk protein) – we look forward to seeing whether these mechanistic findings translate to longer term training studies in various populations.”
