Study
Brazilian researchers at the Universidade Federal de Santa Maria divided 30 adults with tinnitus into 2 groups. They gave one group a daily placebo for 8 weeks, while the subjects in the experimental group received a daily capsule containing 100 milligrams of acai berry extract. This dose was the most effective against tinnitus, according to a small pilot study.

The Brazilians used a product from Farmacia Pharma Nostra.

The researchers determined the severity of their subjects' tinnitus by having them complete the Tinnitus Handicap Inventory (THI).

Results
Tinnitus scores decreased in the acai group and the placebo group by 27 percent and 21 percent, respectively. This means that the average subject's tinnitus problem changed from moderate to mild in both groups. However, this decrease was only statistically significant in the acai group.

Mechanism
There is some evidence that free radical activity plays a key role in tinnitus.

A few years ago, Turkish researchers not only found more markers for free radical activity in the blood of people with tinnitus, but also fewer markers for antioxidant activity. [Audiol Otol. 2016;20(1):17-21.]

The Brazilians found a significant decrease in carbonylated protein and peroxidized lipids in the subjects in the acai group. This indicates a decrease in free radical activity.
