Many beetroot juices you buy at the store don’t say how much nitrate they have, or if they do, the number on the label doesn’t match what scientists find when they test it—so you can’t trust what’s written, and researchers can’t rely on it for studies.

Many beetroot juice bottles don’t say how much nitrate is inside, and when scientists test them, the actual nitrate levels often don’t match what’s on the label—making people doubt the product and messing up science studies.

Most beetroot juice drinks you buy at the store don’t say how much nitrate is in them, and when they do, the numbers are often wrong or missing—so athletes who rely on it for performance don’t know how much to take.

If you buy the same brand of beetroot juice twice, the amount of nitrate can be wildly different between bottles—even if they look identical—because the company isn’t making it the same way every time.

Even if you buy the same brand of beetroot juice again and again, the amount of nitrate can be totally different each time—sometimes way more, sometimes way less—because the way it’s made isn’t consistent.

Even though it's the same brand of beetroot juice, the amount of nitrate can be very different from one bottle to the next — sometimes way more, sometimes way less — which means the company isn’t making it the same way every time.
