About
Beetroot extract is a concentrated source of dietary inorganic nitrate that provides an alternative pathway for nitric oxide production via oral bacteria. A 2013 meta-analysis of 16 RCTs found beetroot juice reduced systolic blood pressure by 4.4 mmHg. A 2017 RCT in older hypertensive adults showed -8 mmHg systolic reduction over 4 weeks.
How It Works
Concentrated source of dietary inorganic nitrate converted to nitrite by oral commensal bacteria, then further reduced to nitric oxide in the stomach and blood vessel walls; this nitrate-nitrite-NO pathway provides an alternative to the enzymatic eNOS pathway, particularly important when eNOS is dysfunctional; betalains provide additional antioxidant and anti-inflammatory effects.
Evidence For Conditions
Side Effects
- Beeturia (red/pink urine — harmless)
- Red discoloration of stools
- Mild gastrointestinal discomfort
- May increase risk of kidney stones in susceptible individuals (oxalate content)
Drug & Supplement Interactions
- Antihypertensives (additive blood pressure lowering)
- PDE5 inhibitors (additive vasodilation)
- Antibacterial mouthwash (eliminates oral bacteria needed for nitrate conversion, abolishing BP effect)
