Meet PeptiStrong®
PeptiStrong® introduces a new dimension to muscle health: clinically studied plant peptides from fava beans that actively signal your cells to support the body in building and maintaining muscle strength, recovery and energy.
While creatine fuels energy and protein provides building blocks, PeptiStrong® speaks directly to your cells, signaling them to perform, recover, and rebuild smarter.

Increase strength
PeptiStrong group showed +17% increase in strength compared to placebo in men and women (3)
Reduce fatigue
PeptiStrong group showed significantly less fatigue at both 48 and 72 hours timepoints (2)
Recover strength faster
PeptiStrong group recovered strength faster back to normal after a period of immobilization (1)
Increase performance during recovery
PeptiStrong group recovered faster and saw +54% increase in performance during recovery period (2)
Increase reps
PeptiStrong group performed double the reps to exhaustion (80% weight of 1 rep max) (3)
Plant-based source
PeptiStrong is a network of cell signaling peptides from the fava bean, and through Nuritas' process, clinically proven benefits are unlocked in a way that the fava bean alone doesn't provide
