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.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'varies significantly' and 'indicating', which suggest likelihood or observation rather than certainty. 'Varies' is not definitive (it doesn't say 'causes' or 'always'), and 'indicating' implies inference from data, not absolute proof.

What's in Your Beet Juice? Nitrate and Nitrite Content of Beet Juice Products Marketed to Athletes.
Scientists tested different bottles of beet juice and found that the amount of nitrate — the stuff that helps athletes — changes a lot from one bottle to the next, even if they’re the same brand. This means companies aren’t making it consistently, just like the claim says.
