Most beetroot juices have very little nitrite, but two popular ones—Superbeets and BeetElite—have way more, and that might change how your body turns nitrite into nitric oxide.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'may alter' to indicate possibility rather than certainty, and 'substantially higher' to suggest a notable difference without definitive proof of causation. 'Is negligible' is descriptive but paired with probabilistic language ('potentially') to qualify the outcome.

negligible (≤0.06 mmol/serving) in most products, but substantially higher (0.14 and 0.22 mmol/serving) in Superbeets and BeetElite, potentially altering nitric oxide production kinetics

What's in Your Beet Juice? Nitrate and Nitrite Content of Beet Juice Products Marketed to Athletes.
Scientists checked how much nitrite is in popular beet juice drinks and found that most have almost none, but two brands—Superbeets and BeetElite—have way more, just like the claim said.
