Drinking beetroot juice every day for a month is safe for people with high blood pressure—it doesn’t cause any dangerous side effects, and the only harmless things you might notice are pink urine or oddly colored poop.
Claim Language
Language Strength

Uses probability language (may, likely, can)
The claim uses 'is well tolerated' and 'no serious adverse events'—these phrases suggest likelihood or acceptability rather than certainty, and avoid absolute terms like 'causes' or 'prevents.'

Evidence from Studies
Supporting (1)
Dietary nitrate provides sustained blood pressure lowering in hypertensive patients: a randomized, phase 2, double-blind, placebo-controlled study.
This study gave people with high blood pressure beetroot juice every day for a month and found it was safe, with no serious problems — just harmless things like pink urine or stool, which are normal when you eat beets.
