Beta-Endorphin
Beta-Endorphin (β-Endorphin)
The body's most potent endogenous opioid peptide. Produced during exercise, stress, and excitement. Responsible for the 'runner's high' and natural pain relief.
Mechanism of Action
Beta-endorphin binds to mu-opioid receptors in the brain and spinal cord, producing analgesia, euphoria, and anxiolysis. It also modulates immune function and has anti-inflammatory properties.
Health Claims & Evidence
Potent natural pain relief
Mood elevation and euphoria
Immune modulation
Short-Term Effects
Analgesia, euphoria, anxiolysis.
Long-Term Effects
Rapid tolerance development limits long-term utility.
Side Effects
Tolerance, potential dependency, respiratory depression at high doses.
Contraindications
Not for self-administration due to opioid risks.
