Celery is a vegetable used for lowers systolic and diastolic blood pressure. NutriDex grades the human evidence as Moderate. Celery is very low in calories and sugar but supplies meaningful vitamin K, folate and potassium, plus the signature flavones apigenin and luteolin and aromatic phthalides (3-n-butylphthalide). A 2025 meta-analysis of 9 RCTs (511 adults) found celery preparations significantly lowered systolic and diastolic blood pressure, fasting glucose and triglycerides, and a triple-blind crossover trial of celery seed extract cut systolic pressure by roughly 11 mmHg. Population studies of dietary flavones (the apigenin/luteolin subclass) link higher intake to modestly lower breast and esophageal cancer risk and lower cardiovascular mortality, though these flavone data are observational rather than celery-specific.
Purported Benefits
✓Lowers systolic and diastolic blood pressure
✓Reduces fasting glucose and triglycerides
✓Very low calorie, hydrating, high water content
✓Source of vitamin K, folate and potassium
✓Flavones linked to lower CVD mortality
Dosing & Compounds
Typical Dose
Standard serving: 1 cup chopped, raw (101 g). Eat whole (with skin where edible); favour whole fruit over juice.
Generally very safe as a food. Celery is a recognized allergen and can trigger oral allergy syndrome or, rarely, anaphylaxis. It contains photosensitizing furocoumarins (psoralens) that can cause phytophotodermatitis with heavy skin contact plus sun. Concentrated celery seed extracts may add to the effect of antihypertensive drugs and are best avoided in pregnancy (uterine-stimulant tradition) and with anticoagulants given the vitamin K content; whole-food amounts pose little warfarin concern. Educational only — always check with your doctor or pharmacist before combining Celery with any medicine.
