How do pump formulas work?
Pump formulas are supplements designed to increase blood flow to your muscles during exercise, giving you that “muscle pump” effect.
They usually contain nitric oxide (NO) precursors such as citrulline malate, arginine and nitrates.
These ingredients boost nitric oxide production in the body, which helps:
- Widen blood vessels (vasodilation) for improved circulation
- Deliver more oxygen and nutrients to working muscles
- Enhance endurance, performance, and recovery
The result is not just a bigger pump look, but also practical benefits like better stamina and reduced fatigue during workouts.
