    Metabolic Syndrome

    Preliminary evidence suggests acai berry may improve metabolic health.
    Metabolic Syndrome
    ×
    Açaí berries are high in polyphenols and therefore have a strong antioxidant action.1 In a pilot study, supplementing with 100 grams per day of açaí berry pulp for 30 days was found to lower blood glucose, insulin, and total and LDL-cholesterol levels in ten overweight adults with metabolic disease.2 However, in a placebo-controlled trial with 37 participants with metabolic syndrome, treatment with 325 mL of an açaí berry beverage (providing 370 mg of gallic acid) twice daily did not improve markers of glucose and lipid metabolism.3

    Type 2 Diabetes

    Preliminary evidence suggests açai may have benefits in type 2 diabetes.
    Type 2 Diabetes

    Açai berry is reported to be a traditional remedy for diabetes. A pilot trial in ten overweight but otherwise healthy adults found taking 100 grams of açai pulp per day for one month led to decreases in fasting glucose and insulin levels as well as after-meal blood glucose, triglyceride, total cholesterol, and LDL-cholesterol levels.4 Positive metabolic and anti-diabetic effects have been demonstrated in animal models of type 2 diabetes.5,6 Clinical trials evaluating açai’s effect in people with type 2 diabetes are needed.

    Type 1 Diabetes

    Açaí is rich in antioxidants and has been used traditionally to treat diabetes.
    Type 1 Diabetes

    Açaí is reported to be a traditional remedy for diabetes. Oxidative stress may contribute to diabetes onset and its complications, and açaí is rich in antioxidant polyphenols such as anthocyanins. Studies in people without diabetes show açaí consumption can raise antioxidant status in the body and improve lipid levels and blood vessel function.7,8,9 In animal research, açaí extract reduced diabetes-related kidney damage and dysfunction; however, direct evidence for açaí’s benefits in people with type 1 diabetes is lacking.10

  • Menstrual and PMS Support

    Dysmenorrhea

    Açaí is a traditional remedy for dysmenorrhea, and there is preliminary evidence that some anthocyanins found in açaí may help with dysmenorrhea symptoms.

    Açaí is reported to be a traditional remedy for dysmenorrhea. There is preliminary evidence that anthocyanins from bilberry, some of which are also found in açaí, may help with dysmenorrhea symptoms.11 However, there have been no clinical trials investigating açaí’s effect on dysmenorrhea.

  • Heart and Circulatory Health

    Anemia

    Açaí, which contains small amounts of iron, has been traditionally used to help treat anemia.

    Açaí contains iron (approximately 1.5 to 5 mg per 3.5 ounces of fruit).13 Although it has been traditionally used to help treat anemia, the amount of iron in açaí is not likely to be abundant or absorbable enough to have a significant effect.

  • Immune System Support

    Fever

    Roasted, crushed açaí seeds, consumed as tea, are a traditional remedy for fever.

What Are Star Ratings?
×
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

Açaí juice is a major dietary component of Brazilian diets, especially in the Pará region. It is often eaten at breakfast with cassava meal (manioc) or with tapioca and sugar. The açaí fruit is rich in nutrients and is found in many Brazilian prepared foods. The fruit is most popularly used to make juice, but is also found in ice cream, popsicles, and various desserts.

Açaí seeds can be crushed to produce a green oil that has been used as a folk remedy for scrofula (a type of tuberculosis). The roasted, crushed seeds, consumed as tea, are a traditional remedy for fever. Tea made from the root is a folk remedy for jaundice and anemia. Tea made from the grated fruit rind has been used topically as a wash for skin ulcers. Boiled preparations of açaí root have been used traditionally to treat many diseases, including diabetes, hepatitis, malaria, kidney disease, and dysmenorrhea (menstrual pain).

No clinical trials of açaí for the prevention or treatment of any health condition have been published in the medical literature.
