Lab Tested. Science Backed.
Small Berry.
Serious Antioxidants.
Aronia berries aren't just a wellness trend — they're one of the most antioxidant-dense fruits on the planet, with a growing body of peer-reviewed research behind them. And now we've tested the actual juice that goes in every can. Here's what the science says.
What's In Every Can
Most "antioxidant" drinks ask you to take their word for it. We sent ours to the lab. In April 2026, Medallion Labs — an independent food-testing laboratory in Minneapolis — analyzed the same aronia juice we put in every Arozen can. These are the verified numbers, per 12 fl oz can:
75
mg per can — Anthocyanins
Anthocyanin Content
The deep-purple antioxidant pigment aronia is famous for — about 3× what you'd get from blueberries
122
mg per can — Total Polyphenols
Total Polyphenols
The broad family of plant compounds studied for cardiovascular and immune health support*

Independently Tested by Medallion Labs
Our aronia juice — the exact juice in every can — was independently analyzed by Medallion Labs in Minneapolis. We publish our results because we have nothing to hide.

How Aronia Compares
Gram for gram, aronia is in a different league from the fruits usually called "superfoods." Two ways to see it:
What the Research Shows
Aronia berries (Aronia melanocarpa) have been the subject of dozens of peer-reviewed studies published in journals indexed by the National Institutes of Health (PubMed). Below are key findings from human clinical trials and meta-analyses — the gold standard of nutritional research.
A meta-analysis of controlled clinical trials found that daily aronia supplementation for 6–8 weeks significantly reduced systolic blood pressure and total cholesterol — key risk factors for cardiovascular disease. Effects were most pronounced in adults over age 50.

Journal of Dietary Supplements. "Daily supplementation with Aronia melanocarpa (chokeberry) reduces blood pressure and cholesterol: a meta-analysis of controlled clinical trials."

A double-blind, placebo-controlled randomized trial in 66 healthy men found that 12 weeks of aronia consumption significantly improved endothelial function (blood vessel flexibility) and positively modulated gut microbiota composition, indicating potential to maintain cardiovascular health.
Rodriguez-Mateos et al. (2019).
American Journal of Clinical Nutrition. "Effects of aronia berry (poly)phenols on vascular function and gut microbiota: a double-blind randomized controlled trial in adult men." NCT03041961.

A 12-week randomized controlled trial found aronia polyphenol consumption reduced total cholesterol by 8% and LDL ("bad") cholesterol by 11% compared to placebo — without any reported adverse effects.
Xie et al. (2017).
Nutrition Research. "Aronia berry polyphenol consumption reduces plasma total and low-density lipoprotein cholesterol in former smokers without lowering biomarkers of inflammation and oxidative stress: a randomized controlled trial." NCT01541826.

A 12-week double-blind, placebo-controlled trial in 102 prehypertensive adults found aronia extract supplementation produced significant improvements in arterial stiffness (pulse wave velocity) and augmentation index — two key markers of cardiovascular health.
Le Sayec et al. (2022).
Clinical Nutrition. "The effects of Aronia berry (poly)phenol supplementation on arterial function and the gut microbiome in middle aged men and women." NCT03434574.

A clinical study in patients who had survived a myocardial infarction found that 6 weeks of aronia extract supplementation significantly reduced markers of oxidative stress and inflammation, including oxidized LDL, hs-CRP, and MCP-1 — compared to placebo.
Naruszewicz et al. (2007).
European Journal of Nutrition. "Combination therapy of statin with flavonoids rich extract from chokeberry fruits enhanced reduction in cardiovascular risk markers in patients after myocardial infarction."

A 2022 comprehensive review published in PMC summarized the research to date, confirming that aronia berry compounds show antioxidant, anti-inflammatory, cardioprotective, antidiabetic, hepatoprotective, and immunomodulatory properties — with multiple active clinical trials underway.

The Key Compounds
Aronia's antioxidant power comes from a rich and diverse mix of phytonutrients that work together:
🫐 Anthocyanins
Aronia's primary antioxidant pigments — responsible for its deep purple color. Multiple distinct types provide broad-spectrum antioxidant coverage.*
🌿 Quercetin
A flavonoid found in aronia, studied extensively in clinical trials for immune function and cardiovascular health support.*
🍇 Proanthocyanidins
Condensed tannins responsible for a large share of aronia's total antioxidant activity. Associated with cardiovascular and metabolic health.*
🌱 Chlorogenic Acid
A hydroxycinnamic acid that contributes meaningfully to aronia's antioxidant activity. Currently being studied in cancer clinical trials.
💊 Cyanidin-3-O-Galactoside
The primary anthocyanin in aronia. Shown to scavenge free radicals more effectively than individual anthocyanins in isolation.*
💪 Dietary Fiber
Aronia is exceptionally high in natural fiber, supporting digestive health and gut microbiome diversity — a link identified in multiple aronia clinical trials.*
Why We Test Everything
Anyone can put "antioxidant rich" on a label. We prefer proof. That's why we independently test our aronia juice with Medallion Labs and our berry powder with Eurofins — and why we point you to real peer-reviewed research, not marketing claims.
The science on aronia berries is still growing. Researchers are actively studying these berries in ongoing clinical trials. What's already established is compelling — and we're proud to build our products around a berry with this kind of scientific backing.
Research Disclosure: Lab data for our canned beverages is from independent testing of Arozen Aronia Juice by Medallion Labs (Report #184634, April 2026). Per-can values reflect a 12 fl oz (355 mL) can. The anthocyanin, polyphenol and DPPH analyses are not within Medallion's ISO/IEC 17025 accreditation scope. Our Aronia Berry Powder is separately tested by Eurofins Scientific (Lot #ORGAFP-23282, Report #4308798-0, December 2023) and those figures reflect the dried powder only.
