Recommendation: Standard doses are usually reasonable; use caution before surgery or with anticoagulants.
Pomegranate Extract
Antioxidant ·Moderate evidence ·Reviewed May 2026
Pomegranate extract is a polyphenol-rich preparation studied for blood pressure, endothelial function, LDL oxidation, and inflammatory markers. Human evidence is strongest for small blood pressure effects and oxidative-stress markers, while cardiovascular outcome data are not established. Juice products can add sugar, so capsules or unsweetened extracts are often preferred for metabolic use.
What it's good for
The bottom line
Evidence rating moderate. Most-documented uses: may modestly lower systolic blood pressure, supports endothelial nitric oxide signaling, reduces oxidative modification of ldl in some studies. 3 sources indexed (2004–2017), with 3 interaction records on file.
The science
How it works, mechanistically.
Core mechanism
Punicalagins, ellagitannins, anthocyanins, and downstream urolithin metabolites can reduce oxidative modification of LDL, support nitric oxide bioavailability, and modulate inflammatory signaling. Some studies suggest ACE-related and endothelial effects that may contribute to modest blood pressure reductions. Gut microbiome conversion to urolithins varies between individuals and may influence response.
Class
Punicalagin-rich vascular polyphenol extract
Found in food
Pomegranate arils, Pomegranate juice, Pomegranate molasses in small culinary amounts
Low-status signs
None - pomegranate is not an essential nutrient and has no deficiency state
Absorption
Water-soluble; take with food
Dosing
Dosing & protocol.
Common range
250-1,000 mg/day standardized extract or about 240 mL/day unsweetened pomegranate juice
Recommended form
Capsule standardized to punicalagins or total polyphenols
Take with meals for tolerability. Juice forms contribute carbohydrate and calories; microbiome conversion to urolithins is variable.1
Forms
Forms & what to buy.
Ranked by evidence and value.
Punicalagin Standardized Capsule Recommended
Most practical low-sugar form with disclosed active polyphenols. Take with meals.
Pomegranate Juice
Food form with clinical studies but adds sugar and calories. Take with meals.
Pomegranate Powder Extract
Variable potency unless standardized. Mix with food or drink.

Goals
Goal-based dosing.
Blood Pressure Support
Dose: 250-1,000 mg/day extract or 240 mL/day juice1,3
Timing: With meals
Monitor blood pressure response over 4-8 weeks.
Endothelial Function Support
Dose: 500 mg/day extract
Timing: With a meal
Best paired with exercise and cardiometabolic risk management.
LDL Oxidation Support
Dose: 500-1,000 mg/day extract3
Timing: With meals
LDL oxidation markers are not routine clinical targets; monitor standard lipids separately.
