Celery's Blood Pressure Effect Isn't Just the Nitrates
Celery's blood-pressure reputation gets credited to the same mechanism as beet juice — a 2025 meta-analysis points to a second compound doing real work too.
Celery contains dietary nitrates, similar to beets, which convert to blood-vessel-relaxing nitric oxide. But celery also contains apigenin and 3-n-butylphthalide — compounds with their own vasodilatory, calcium-channel-blocking, and diuretic properties, independent of the nitrate pathway.
Key Findings
- A 2025 meta-analysis (10 trials, 511 people) found real drops in blood pressure, glucose, and triglycerides
- Apigenin works through a mechanism independent of the nitrate-to-nitric-oxide pathway
- Celery is not just a milder beet juice — the two mechanisms are complementary, not redundant
- Whole stalks, not just juice, retain both the nitrates and the apigenin
The 2025 meta-analysis
A 2025 meta-analysis pooling 10 randomized controlled trials and 511 participants found celery consumption produced significant reductions in systolic and diastolic blood pressure, fasting glucose, and triglycerides.1
What apigenin does on its own
Separate apigenin-specific research shows the compound reduces inflammatory protein expression and has anti-atherosclerotic effects through oxidative stress, lipid metabolism, and blood-pressure-regulating pathways distinct from nitrate conversion.2 Celery appears to work through vasodilatory, diuretic, and calcium-channel-blocking mechanisms layered on top of its nitrate content.
Why this matters for how you'd use it
Celery isn't just a milder version of beet juice — it's working through a partly independent mechanism, so the two aren't fully redundant if blood pressure is the goal.
The practical takeaway
- Whole stalks, not just juiced celery, retain the phthalide and apigenin content alongside the nitrates
- This is a dietary pattern, not a substitute for prescribed blood pressure medication
- Celery and beets can be viewed as complementary, not interchangeable, for this purpose
