Oxytocin is a nine-amino acid peptide hormone produced naturally in the hypothalamus and released by the posterior pituitary gland, serving as both a hormone and neurotransmitter that works throughout the body and brain. While famous as the "love hormone" for its role in childbirth, breastfeeding, and social bonding, oxytocin plays far more diverse roles including stress regulation, metabolic function, cardiovascular health, and inflammation control. In the central nervous system, oxytocin influences trust and social cognition, emotional bonding, empathy, and reduction of social anxiety, while also modulating stress responses by reducing cortisol levels, dampening amygdala activity, and promoting parasympathetic nervous system activation.

Beyond its psychological effects, oxytocin demonstrates significant peripheral physiological effects including cardiovascular function through blood pressure regulation and anti-inflammatory effects on blood vessels; metabolic regulation by influencing insulin sensitivity, appetite and satiety, and fat and glucose metabolism; and anti-inflammatory actions that reduce systemic inflammation markers and support tissue healing. Clinical research has explored oxytocin for various mental health applications including social anxiety disorder, autism spectrum disorder (improved social cognition in some studies), PTSD, and general anxiety, with studies showing anxiolytic effects without sedation. Exciting metabolic health research suggests oxytocin may influence weight management through reduced caloric intake, enhanced fat oxidation, improved insulin sensitivity, and potential support for weight loss interventions.

The most common route of administration in research is intranasal (typical doses 10-40 IU per administration) with rapid absorption and effects beginning within 30-45 minutes, while subcutaneous administration (10mg/6000 IU typical dose) provides slower onset but longer duration and better bioavailability. Research generally indicates oxytocin is well-tolerated with few side effects, though occasional nasal irritation with spray form and rare reports of headache or dizziness have been noted.
