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 a possible but not certain effect, which falls under probability language. 'Are' is used for factual measurement, but the key causal implication ('potentially altering') introduces uncertainty, making the overall strength probabilistic.

What's in Your Beet Juice? Nitrate and Nitrite Content of Beet Juice Products Marketed to Athletes.
Scientists tested popular beet juice drinks and found that most have very little nitrite, but two specific brands—Superbeets and BeetElite—had much more nitrite, which might change how your body makes nitric oxide. This matches what the claim says.
