Acai Extract
Also known as: Açaí, Euterpe oleracea, Euterpe oleracea Mart., açaí extract, acai berry extract
Effective Dosage
No established dose from provided studies
What the Science Says
Acai extract comes from the fruit of the Euterpe oleracea palm tree, native to the Amazon. It is rich in anthocyanins and other polyphenols that have antioxidant and anti-inflammatory properties. One small clinical trial (30 people) found that 100 mg daily for 3 months reduced discomfort from chronic tinnitus (ringing in the ears), and animal studies suggest it may help protect the heart from chemotherapy-related damage and improve blood sugar control in diabetic models — though these findings have not yet been confirmed in human trials.
What It Doesn't Do
Not proven to cause weight loss. No human evidence it fights cancer. No proven benefit for blood sugar in humans. Not a substitute for medical treatment. The 'superfood' label is mostly marketing — the human clinical evidence is very thin. Don't assume it's safe to combine with cancer drugs like methotrexate or tamoxifen — lab data suggests it may increase their toxicity, including to healthy cells.
Evidence-Based Benefits
Acai extract is rich in antioxidants, particularly anthocyanins, which may help reduce oxidative stress and inflammation. Some studies suggest potential benefits for heart health and weight management, although results are not universally consistent.

Absorption & Bioavailability
Unknown — no pharmacokinetic or absorption studies were included in the provided data. Anthocyanins as a class are generally considered to have variable and often limited oral bioavailability.
Red Flags to Watch For
- Lab data shows acai extract may increase toxicity of cancer drugs (methotrexate, tamoxifen) to normal healthy cells — do not combine with chemotherapy without medical supervision
- The only human clinical trial involved just 30 people for one specific condition (tinnitus); results cannot be generalized to other health claims
- Most positive findings come from animal or cell studies, which frequently do not translate to benefits in humans
- Over 1,000 supplement products contain acai, but the ingredient is largely unregulated and dosing is inconsistent across products
- Anti-inflammatory and antidiabetic effects shown only in rat models — no human trials confirm these benefits
