About
About Oxytocin
Oxytocin is a neuropeptide hormone produced in the hypothalamus with roles in social bonding, stress response, and metabolic regulation. In optimization medicine it is used off-label for anxiety reduction, libido support, and gut motility improvement. Research suggests it may also reduce food intake and improve body composition in some populations. Compounded intranasal and subcutaneous formulations are available through licensed providers.
Science
Mechanism of Action
Binds oxytocin receptors throughout the brain and peripheral tissues, modulating the HPA stress axis, reducing cortisol, and activating reward pathways. Peripheral oxytocin receptors in adipose tissue and the gut contribute to its metabolic effects.
Dosing
Typical Protocol
