How Much Beetroot Juice Should You Drink? A Dosage Guide
The Short Answer: 8 oz (250 ml) Per Day
For nearly every research-backed benefit — blood pressure, endurance, brain health — the clinical dose is 8 oz (roughly 250 ml) of pure beetroot juice per day. That's exactly one Pomona Organic Beetroot Juice bottle (8.4 fl oz).
By Goal
Blood pressure support: studies typically used 8 oz daily for 2-4+ weeks, where average systolic readings fell by about 4-10 mmHg in the study groups.
Endurance / workout performance: 8 oz 2-3 hours before exercise. Load 3-6 days beforehand for peak events.
Brain health / focus: 4-8 oz with breakfast. Cerebral blood flow rises within hours.
General wellness: 4-8 oz daily. This provides antioxidants (betalains), folate, manganese, and enough nitrates to matter.
Can You Drink Too Much?
Above 16 oz per day, side effects (loose stools, blood-pressure crashes, oxalate load) become more likely without additional benefit. Stick to 8-16 oz per day maximum.
How Long Until You See Results?
Blood pressure and endurance: hours (single dose) to 4 weeks (sustained). Brain: hours (cerebral blood flow) to months (long-term cognitive markers). Antioxidant / anti-inflammatory: weeks of consistent intake.
