FAQ

Why combine L-Arginine and L-Citrulline instead of taking just one?

Great question! The two work together—L-Citrulline helps your body regenerate L-Arginine, which in turn supports nitric oxide levels. Together, they help maintain circulatory balance and steady energy for longer-lasting performance.

Can this help with my workouts?

Yes. Many people notice more sustained stamina and smoother post-activity recovery with consistent use. It’s nutritional support for how your body moves, not a stimulant.

Do I need to take it only before exercise?

Not necessarily. While some prefer it pre-workout, daily use helps maintain nitric oxide support more consistently—think ongoing support for circulatory balance, endurance, and vitality.

Will this replace my pre-workout or energy drink?

Not exactly—there’s no caffeine here. It supports natural oxygen and nutrient delivery, so many users choose to pair it with their existing routine for a steady, jitter-free complement.
