Aronia (Aronia melanocarpa), or black chokeberry, is a dark, sour berry very high in anthocyanins and other polyphenols. It is sold as juice, powder and extract.
Also known as: black chokeberry, chokeberry, Aronia melanocarpa, aronia berry.
A 12-week trial in healthy men used an extract with 116 mg of polyphenols (about 75 g of berries) or a whole-fruit powder (about 10 g of berries) a day (Istas 2019). These are study protocols, not a recommendation.
It is sold in the US as a dietary supplement. Under the 1994 dietary supplement law (DSHEA), FDA does not approve dietary supplements before they are marketed, and the maker, not FDA, is responsible for safety and labeling.
What studies show: the evidence is mixed. A 2021 meta-analysis found 6 to 8 weeks of aronia extract lowered systolic blood pressure and total cholesterol, more so in adults over 50 (Hawkins 2021). A stricter 2025 meta-analysis of 10 trials (666 people) found no significant effect on weight, blood sugar, cholesterol or blood pressure overall, rated the certainty of evidence very low, and noted one subgroup where fasting blood sugar rose in people 50 or younger (Frumuzachi 2025). In 66 healthy men, 12 weeks of aronia extract or powder improved artery function (flow-mediated dilation) by about 1% over placebo (Istas 2019).
Safety: the sources here do not report safety problems. The sources here do not describe drug interactions.
We could not find a single published half-life or time to peak for aronia that applies to a supplement dose, so we do not list one. Plant extracts are mixtures of many compounds, so no single figure would describe them.
