This study tested the antioxidant and anti-inflammatory properties of a commercial juice blend (MonaVie Active), which contains a mixture of fruits and berries, including Acai berry as its main ingredient. The study was a randomized, double-blinded, placebo-controlled, crossover trial with 12 healthy subjects. Blood samples at 1 and 2 hours following consumption of the Monavie Active juice blend as tested for antioxidant capacity.
They found that the antioxidants in the Monavie Active juice blend penetrated and protected cells from oxidative damage. At both 1 and 2 hour intervals, they found that the subjects who took the Monavie Active juice blend showed an increase in serum antioxidants, and also inhibition of lipid peroxidation - Lipid peroxidation refers to the oxidative degradation of lipids. It is the process whereby free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage.[2]
Acai Juice Study 2
Pharmacokinetics of anthocyanins and antioxidant effects after the consumption of anthocyanin-rich acai juice and pulp (Euterpe oleracea Mart.) in human healthy volunteers.

This study performed a 4 way crossover trial with Acai pulp and Acai juice compared to applesauce, and a placebo non-antioxidant drink. 12 healthy volunteers consumed 7ml/kg of the beverages after a washout phase and an overnight fasting period. Their plasma was sampled repeated over a 12 hour period, and urine sampled over a 24 hour period after consuming the beverages. They found that plasma antioxidant capacity was significantly increased by the Acai juice and acai pulp, where the test subjects had an increase in plasma antioxidant capacity of up to 2.3 and 3 fold, respectively.
Acai Berry Study 3 - OptiAcai

This study evaluated the antioxidant capacities of freeze-dried acai fruit pulp powder (OptiAcai). The researchers found that it had exceptional activity against superoxide - "the highest of any food reported to date against the peroxyl radical as measured by the oxygen radical absorbance capacity assay with fluorescein as the fluorescent probe". It was also found that Acai had mild activity against both the peroxynitrite and hydroxyl radicals. What's noteworthy is that Acai antioxidants are able to enter human cells in fully functional form. Below is a direct quote from the study:
In the total antioxidant (TAO) assay, antioxidants in acai were differentiated into "slow-acting" and "fast-acting" components. An assay measuring inhibition of reactive oxygen species (ROS) formation in freshly purified human neutrophils showed that antioxidants in acai are able to enter human cells in a fully functional form and to perform an oxygen quenching function at very low doses.
The study also investigated the bioactivities related to anti-inflammatory and immune functions of Acai, and it was found to be a potential cyclooxygenase (COX)-1 and COX-2 inhibitor. (Inhibition of COX can provide relief from symptoms of inflammation and pain).
Acai Berry Juice Study 4

This study involves evaluation the antioxidant potency of several commonly consumed polyphenol rich beverages including pomegranate juice, apple juice, Acai juice, black cherry juice, blueberry juice, red wines, iced tea, black tea, green tea, and white tea. An overall antioxidant potency composite index was calculated for each of these, and it was found that the pomegranate juice had the highest antioxidant potency - at least 20% higher than any of the other beverages. They ranked the beverages in the following order of antioxidant potency:
Pomegranate juice > red wine > Concord grape juice > blueberry juice > black cherry juice, açaí juice, cranberry juice > orange juice, iced tea beverages, apple juice
The above are just a handful of the many studies done on the antioxidant potency of Acai - there are many more which are not listed here, but the general theme is that Acai is a potent antioxidant and anti-inflammatory, and has numerous health benefits.
