What Is Red Spinach?

Red spinach (Amaranthus dubius) is a leafy plant naturally rich in dietary nitrate. Our concentrated, oxalate-free, standardized extract delivers multiple times more naturally occurring nitrate than conventional beet powders in a much smaller serving. Every time.

Your safety matters. That’s why we use a three-step quality testing process ending with independent third party testing before every batch reaches your door.

Why Red Spinach Is Special.

Red spinach has the highest concentration of dietary nitrate from a food source.

Your body converts dietary nitrate into nitric oxide, an important molecule that helps support healthy circulation, exercise performance, and healthy aging.

Unlike beetroot, our concentrated red spinach extract delivers a higher, measured amount of naturally occurring nitrate in a small, convenient serving.
