Product Description
Forget everything you know about beetroot supplements.
RS400™ delivers 4x more dietary nitrates than common beets – packed into just half a tablespoon of pure red spinach extract.
This isn’t your average greens powder trying to do everything. It’s a precision-engineered performance enhancer that does one thing exceptionally well – boosts nitric oxide production for better oxygen delivery to your muscles.
What’s in RS400™
One ingredient – 100% red spinach extract. That’s it.
1 scoop = 400 mg of nitrate (1 serving)
Zero fillers. Zero sugar. Zero oxalates, which are compounds that can bind to minerals and block absorption, are commonly found in beetroot powders, spinach supplements or greens blends.
Zero earthy aftertaste. Just 400 mg of naturally occurring nitrates from ancient red spinach (amaranth) that science is finally catching up to.
100% plant-based, non-GMO and rigorously third-party tested for purity and nitrate levels. We know you’re serious about performance, so we made sure you get what you pay for.
How to Use It
RS400™ comes as a concentrated powder – mix one scoop into water, juice or your pre-workout smoothie.
No choking down horse pills or dealing with messy measuring. Take it 1-2 hours before training for optimal results.
How it Works
Here’s what happens – dietary nitrates convert to nitric oxide in your body, which dilates blood vessels and improves oxygen delivery to working muscles.
Result – better endurance, reduced fatigue during training and faster recovery between sets. Clean energy without the caffeine crash, powered by your body’s own circulatory system working more efficiently.
If you’re tired of choking down beetroot juice or dealing with messy powders that promise the world and deliver mediocrity, RS400™ cuts through the noise. One ingredient, maximum impact, zero compromise.
Use what works best, not what’s most popular.
