RS400 delivers more plant-based nitrates than common sources like beets and greens. Here’s how it stands apart:
RS400 provides significantly more dietary nitrate per serving than common sources like beets or spinach, offering a concentrated, plant-based option to complement your active lifestyle.
Skip the mess, earthy taste, and oxalates common to beetroot. RS400 delivers high-nitrate red spinach extract in a clean, concentrated, and easy-to-use form—without the hassle.
RS400 is rigorously 3rd party tested for nitrate levels, pesticides, and many other chemicals, but as a single ingredient botanical food with a nutrition facts panel vs supplement panel, NSF and Informed Sport are unnecessary.
We use the HPLC-UV testing method. The nitrate is naturally occurring in the plant, and there are 400mg of naturally occurring nitrate in every serving.
Red Spinach, also known as Amaranth, is an ancient plant that science has only recently discovered for its high nitrate content and ability to boost your body's overall performance. Once primarily used in traditional diets, its performance-enhancing properties are now gaining attention in the world of sports nutrition.
RS400 delivers more than 4x times the nitrate of beets for more nitrate boost. This leads to a stronger body and enhanced exercise performance without the earthy taste or preparation of beetroot.
Red spinach powder can be mixed with smoothies, juices, or sprinkled on salads. It also blends well into soups, stews, and even baked goods for an extra nutritional boost.
Simply take one serving of RS400 daily, ideally 1-2 hours before your athletic activity.
Yes, RS400 is formulated with natural ingredients, making it safe for athletes of all types. However, if you have any specific health concerns or conditions, it’s always a good idea to consult with your healthcare provider before adding a new supplement to your routine.
Yes, RS400 is 100% plant-based, making it suitable for both vegetarians and vegans.
RS400 can be taken alongside other supplements. If you're already using nitrate-based products or have specific dietary concerns, it's best to consult your doctor or nutritionist to ensure compatibility.
