Results from this study2

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

Natural levels measured2

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 participants who practiced Heartfulness meditation, serum oxytocin levels increased.

    Summary · context
    The experimental group practiced guided HFN meditation for 30 days.
    Summary · context
    Biochemical markers (serum oxytocin, β-endorphins, cortisol) were measured at day 30, and day 60.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelRandomized controlled trialMechanism

    In participants of the Heartfulness trial, cortisol levels correlated negatively with serum oxytocin levels.

    In plain wordsIn people in this meditation trial, higher cortisol was linked to lower levels of the body's own oxytocin.
