Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelRandomized controlled trialMechanism

    In patients after open-heart surgery, music listening during bed rest increased the body's own plasma oxytocin versus bed rest only, where levels decreased.

    In plain wordsIn patients after heart surgery, listening to music raised the body's own oxytocin levels, while levels fell with bed rest alone.
