Pomegranate Extract
Antioxidant ·Exploratory record · not publication-reviewed ·Updated July 13, 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 the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Pomegranate Extract is an antioxidant most often used for may modestly lower systolic blood pressure, supports endothelial nitric oxide signaling, reduces oxidative modification of ldl in some studies. NutriStack rates the overall evidence as moderate. A typical adult dose is 250-1,000 mg/day standardized extract or about 240 mL/day unsweetened pomegranate juice, commonly taken as capsule standardized to punicalagins or total polyphenols. This profile indexes 3 sources.
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 0 interaction records on file.
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.
Dosing & protocol.
Take with meals for tolerability. Juice forms contribute carbohydrate and calories; microbiome conversion to urolithins is variable.1
What it actually costs.
Real-world pricing across three quality tiers. Assumes Punicalagin standardized capsule.
Juice can be cheaper per bottle but less targeted and higher in sugar. Updated 2026-06-04.
