The High Nitrate Beet Alternative
Powered by Red Spinach Extract, RS400 delivers much more nitrate than traditional beetroot or spinach, giving you a potent, natural nitric oxide boost to fuel your workouts and boost your athletic performance.
“RS” is for Red Spinach and “400” refers to the 400mg of naturally occurring nitrate in every serving—the optimal, clinically backed amount shown to support stamina, reduce fatigue, and accelerate recovery.
Why Choose RS400?
RS400 offers superior performance benefits compared to lower nitrate sources like beets and greens. Here's why:
Multiple Times Stronger Than Beets and Green Spinach
RS400 provides far more nitrate per serving than beets or spinach, delivering a more potent nitric oxide boost to support increased stamina so you can be stronger for longer.
A Clean Beet Alternative
Forget the mess and earthy taste (and oxalates) of beetroot. RS400 gives you all the nitrate benefits of beets, but in a cleaner, more concentrated, and convenient form—without the mess.
What is Red Spinach?
Red Spinach, also known as Amaranth, is a powerful, nutrient-packed plant that thrives in extreme conditions like high altitudes, strong winds, and droughts. This plant’s natural resilience is why it’s becoming a favorite among athletes who need reliable, sustained energy and stamina.
In recent years, Red Spinach has been recognized for its incredible nitrate content, making it a superior source of nitric oxide to support better blood flow, oxygen delivery, and stamina. When you take RS400, you're tapping into a plant that thrives in harsh conditions—just like you when you're pushing through your toughest workouts.
Clinically Studied Benefits
RS400 is not just another supplement. It’s functional food that’s been clinically tested and to improve athletic performance. In a double-blind, placebo-controlled study with Division I female college soccer athletes, Red Spinach Extract (the key ingredient use was RS400) demonstrated:
Lowered Fatigue Index
Athletes felt less fatigue, enabling them to train and compete at higher intensities for longer periods.
Improved Lactic Acid Clearance
Faster lactic acid clearance meant athletes experienced less muscle burn and quicker recovery between intense efforts.
Increased Capacity for Repeated Exercise
Athletes were able to perform repeated bouts of high-intensity exercise with better sustained performance.
This study, published in the MDPI Journal of Sports Science shows that RS 400 significantly enhances endurance and performance in athletes.
