Support Healthy Blood Flow During Exercise:
Red spinach extract delivers a concentrated nitrate profile that supports nitric-oxide production, helping to support optimized circulation when your muscles need it most.

Enhance Athletic Performance:
Take RS400® about 60 minutes before training or competition to support workout intensity and sustained output—whether on the road, trail, track, or gym floor.

One Pure Ingredient:
RS400® contains a single ingredient: pure red spinach extract powder. No fillers, artificial or natural flavors, sweeteners, or added sugars—just clean, functional nutrition.

Train Hard. Recover Smarter:
Use RS400® daily to support training recovery and resilience, helping you bounce back faster and stay consistent week after week.

Like a well-trained athlete, red spinach thrives under pressure—growing at high altitudes, in strong winds, and in dry conditions. That natural toughness is exactly what RS400® delivers to athletes who expect more from their bodies.
