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 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.

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.

Not all beetroot supplements have the same amount of nitrate—some have so little that they probably won’t do anything noticeable for your body, like improve blood flow or exercise performance.

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.

Not all beetroot juice drinks for athletes have the same amount of nitrate—some have barely any, others have way more—so if you buy one hoping for a certain boost, you might be totally off unless you test it yourself.
