Aronia berries, or chokeberries, are small, dark fruits that grow on shrubs of the Rosaceae family (1Trusted Source).

They’re native to North America but grown in other parts of the world, including across Europe (2Trusted Source).

Traditionally, Native Americans used them as a cold remedy (1Trusted Source).

The berries have a strong mouth-drying effect, so they’re mainly used to make juices, purées, jams, jellies, syrups, teas, and wines (1Trusted Source, 3Trusted Source).

However, they’re also available fresh, frozen, dried, and in powder form.

Summary

Aronia berries are small fruits that leave a dry feeling in your mouth. They’re added to many foods and beverages but also available as a supplement.

Aronia berries are low in calories but pack a nutritional punch, as they’re high in fiber, vitamin C, and manganese (4).

The berries also supply vitamin K, folate, iron, and vitamins A and E.

Plus, they’re an excellent source of beneficial antioxidants, which help protect your cells from potentially harmful molecules called free radicals. Aronia berries are particularly high in anthocyanins, which give the berries their dark blue to black color (5Trusted Source).

Summary

Aronia berries are nutrient dense with minimal calories. They’re a great source of fiber, vitamin C, manganese, and antioxidants.

Aronia berries have anti-inflammatory and antioxidant effects (5Trusted Source, 6Trusted Source).

This may protect your cells from damage and benefit your health in many ways.

Contain powerful antioxidants

These compounds defend your cells from damage caused by free radicals. A buildup of free radicals can cause oxidative stress, which can lead to chronic conditions, such as heart disease and cancer (3Trusted Source).

Aronia berries are an excellent source of polyphenols, which is a group of antioxidants that includes phenolic acids, anthocyanins, and flavanols (3Trusted Source, 8Trusted Source, 9Trusted Source).

Test-tube studies indicate that the antioxidants in aronia berries can inhibit free radical activity (7Trusted Source, 10).

The berries themselves also showed superior antioxidant activity, compared with four other berries (7Trusted Source, 9Trusted Source).

What’s more, another test-tube study that collected blood samples from 30 healthy people found that extracts from aronia berries significantly reduced oxidative stress caused by an antipsychotic medication within 24 hours (11Trusted Source).

Moreover, test-tube studies have linked the antioxidants in these fruits to other impressive health benefits, such as decreased inflammation, as well as reduced bacterial and colon cancer cell growth (12Trusted Source, 13Trusted Source, 14Trusted Source, 15Trusted Source).

May have anticancer effects

Test-tube and animal studies show that the anthocyanins in aronia berries may stop the growth of colon cancer cells (14Trusted Source, 17Trusted Source, 18Trusted Source).

One older test-tube study found that 50 mg of aronia extract reduced colon cancer cell growth by 60% after 24 hours. It’s thought that the potent antioxidant activity of anthocyanins is responsible for this cancer-suppressing effect (14Trusted Source).

Similarly, extracts from the berries may reduce oxidative stress related to breast cancer.

In one older study, these extracts were shown to be beneficial in aiding chemotherapy drugs in the treatment of pancreatic cancer (19Trusted Source).

That said, current research is limited, and human studies are needed to evaluate the relationship between aronia berries and cancer protection.

May benefit intestinal health

Several recent studies have found that the polyphenols in aronia berries have a stimulating effect on the growth of intestinal microbiota, promoting healthy digestion and intestinal health. In addition, this effect has been shown to improve cardiovascular health and lower inflammation in the intestinal lining (15Trusted Source, 20Trusted Source, 21Trusted Source).

May benefit heart health

Due to its antioxidant and anti-inflammatory properties, aronia berries may improve heart health (22Trusted Source, 23Trusted Source).

In particular, they may help people with metabolic syndrome, a cluster of conditions — including high cholesterol and triglyceride levels — that increases your likelihood of heart disease and diabetes (22Trusted Source, 24).

A 2019 study found that aronia supplementation lowered inflammation in epithelial tissues and improved vascular function in healthy subjects (20Trusted Source).

A 2021 review of studies showed that 6 to 8 weeks of daily aronia berry supplements significantly reduced blood cholesterol and systolic blood pressure. The effects were even more pronounced in subjects who were over 50 (25Trusted Source).

Further human research is needed to identify the role that aronia berries may play in heart health.

May provide immune support

Aronia berries may strengthen and support your immune system (12Trusted Source).

A test-tube study noted that aronia berry extracts exhibited strong antibacterial activity against the potentially harmful bacteria Escherichia coli and Bacillus cereus. It exerted this effect by reducing the bacteria’s production of a protective shield called biofilm (13Trusted Source).

In addition, a 3-month study in residents of 6 nursing homes found that those who drank either 3 or 5.3 ounces (89 or 156 mL) of aronia berry juice daily experienced 38% and 55% reductions in urinary tract infections, respectively (26Trusted Source).

Aronia berries may also reduce inflammation by inhibiting the release of pro-inflammatory substances, such as tumor necrosis factor alpha (TNF-ɑ) and interleukin 6 (IL-6), which may boost immune health (12Trusted Source, 27Trusted Source).

Finally, the berries may have antiviral effects.

One study employing young football players found that daily supplementation of aronia berry extract produced significant improvements in iron metabolism, blood antioxidation, and athletic performance (28Trusted Source).

Summary

Aronia berries provide antioxidants. These compounds may have cancer-fighting properties and support your heart and immune health.

Studies indicate that aronia berries are safe to eat and have no serious adverse effects (23Trusted Source, 29Trusted Source).

However, long-term research is needed to verify this.

Keep in mind that aronia berries are very astringent. This can leave a dry, sandpaper-like feel in your mouth. Therefore, you may not want to eat them on their own (3Trusted Source, 30Trusted Source).

Instead, you could add them to foods and drinks, such as yogurt, smoothies, and juices.

Summary

Aronia berries are typically safe to eat with no serious side effects. The only downside is their astringent, mouth-drying effect.

Though you may not find aronia berries in your local grocery store, they’re widely available in health food stores and online.

They’re often made into juice and are a key ingredient in jams, purées, syrups, teas, and wines (1Trusted Source, 3Trusted Source).

Here are some ways to add aronia berries to your diet:

  • Raw. They can be eaten fresh or dried as a snack, but their mouth-drying effects may not be for everyone.
  • Juices and smoothies. Aronia berries or their juice can be combined with other fruits, such as pineapples, apples, or strawberries, to make a refreshing drink.
  • Baking. You can easily add them to muffins, cakes, and pies.
  • Jams and desserts. Mix aronia berries with sugar to make different jams and tasty treats.
  • Tea, coffee, and wine. Aronia berries can be found as an ingredient in teas, wine, and coffee.

The berries can also be taken as a supplement in powdered or capsule form, with serving and dosing recommendations varying by brand.

A typical serving suggestion is to add one teaspoon of aronia berry powder to a juice, yogurt, or smoothie.

The capsules can be made from freeze-dried berries or extract. Therefore, serving recommendations vary considerably.

Two human studies on the heart-health effects of the berries used 300 mg of extract daily (23Trusted Source, 24Trusted Source).

However, as supplements are not regulated, it’s difficult to identify a therapeutic and safe recommended dose.

Still, aronia berries have not shown any side effects, even when taken in concentrated doses (23Trusted Source, 29Trusted Source).

If you’re interested in trying aronia berry supplements, speak with your healthcare professional before purchasing a product.

Summary

Aronia berries can easily be added to many foods and drinks. They can also be purchased as a powder or capsule supplement.

Aronia berries, or chokeberries, grow on shrubs of the Rosaceae family.

They’re rich in fiber, vitamin C, and powerful antioxidants that may have heart-healthy, immune-boosting, and anticancer properties.

You can add fresh aronia berries to many recipes, try them in juices, jams, and syrups, or use them as a supplement.
