Side Effects of Acai Supplements

Acai berries come from South American rain forests, where they are harvested from the acai palm tree. These berries are similar to grapefruits and have gained popularity among weight-loss and energy supplement enthusiasts as a "superfood." While acai berries are a plentiful source of antioxidants, fiber and good cholesterol, the "superfood" qualities are still to be scientifically proven, according to Katherine Zeratsky of the Mayo Clinic. Those consuming acai supplements should be aware of possible side effects.

Possible Drug Interactions

• Supplements in general are not tested significantly in the United States. No Food and Drug Administration (FDA) approval is required for supplements. There are still many questions about how the supplement may interact with prescription and other medications. Acai may interfere with chemotherapy drugs, according to Memorial Sloan-Kettering Cancer Center. More research needs to be done to confirm how acai interacts with other drugs.

Allergic Reaction

• Those with allergic reactions or sensitivities to pollen or similar berries may also have a reaction to acai berry supplements. Similar berries include raspberries and blueberries. Allergic reactions include hives and difficulty breathing. Those with serious allergy conditions should consult a doctor before consuming acai supplements.

Digestive Issues

• Because the acai berry contains a lot of fiber, it is touted as a weight-loss supplement. Overconsumption of the berry and its fiber can result in gas and possibly diarrhea. While fiber helps the body maintain regular gastrointestinal function, too much causes stomach upset, preventing the intestines from absorbing food before it is properly digested.
