    Acai

    Ya, Acai is very popular in the US right now. I bought two bottles when I was there. You got to store it in the Fridge once it is open. I am not sure if they do international shipping. The best form to get is actually the powder, not the tablets. Check out this website puritan.com

    Don't fall for the Acai berry scam. It doesn't do anything more than other berries and it certainly doesn't have more antioxidants and no magic fat burning or other health benefits (compared to other berries or whole foods and juices).

    Healthy? Maybe.
    Overpriced? Definitely.
    Exagerrated or false health claims? Absolutely.

    The Australian Consumer Association, the US consumer reports and plenty of other institutions looked into it and issued warnings in recent years... google is your friend.

    Here's some of the scientific data on ACAI berries and the MovieVie product hyped above. Looks like its been studied quite in depth, especially for its very high antioxidant (oxidant scavenging) capacity.

    As for phytochemicals, it contains Anthocyanins and polyphenolic compounds, which contribute to the antixidant capacity.

    Antioxidant capacity and other bioactivities of the freeze-dried Amazonian palm berry, Euterpe oleraceae mart. (acai). Schauss AG, Wu X, Prior RL, Ou B, Huang D, Owens J, Agarwal A, Jensen GS, Hart AN, Shanbrom E. J Agric Food Chem. 2006 Nov 1;54(22):8604-10.

    The fruit of Euterpe oleraceae, commonly known as acai, has been demonstrated to exhibit significantly high antioxidant capacity in vitro, especially for superoxide and peroxyl scavenging, and, therefore, may have possible health benefits. In this study, the antioxidant capacities of freeze-dried acai fruit pulp/skin powder (OptiAcai) were evaluated by different assays with various free radical sources. It was found to have exceptional activity against superoxide in the superoxide scavenging (SOD) assay, 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 (ORACFL), and mild activity against both the peroxynitrite and hydroxyl radical by the peroxynitrite averting capacity (NORAC) and hydroxyl radical averting capacity (HORAC) assays, respectively. The SOD of acai was 1614 units/g, an extremely high scavenging capacity for O2*-, by far the highest of any fruit or vegetable tested to date. Total phenolics were also tested as comparison. 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. Furthermore, other bioactivities related to anti-inflammation and immune functions were also investigated. Acai was found to be a potential cyclooxygenase (COX)-1 and COX-2 inhibitor. It also showed a weak effect on lipopolysaccharide (LPS)-induced nitric oxide but no effect on either lymphocyte proliferation and phagocytic capacity.

    Int J Food Sci Nutr. 2005 Feb;56(1):53-64. Institute of Nutritional and Food Sciences, University of Bonn, Bonn, Germany.

    The antioxidant capacities of 11 commercial and non-commercial samples of Euterpe oleracea Mart. (açaí) fruit pulp were studied with the total oxidant scavenging capacity assay in a modified and automated version against three reactive oxygen species. The antioxidant capacities of all purple açaí samples were found to be excellent against peroxyl radicals, good against peroxynitrite and poor against hydroxyl radicals compared with common European fruit and vegetable juices recently analysed. In all cases the correlation between sample concentration and antioxidant capacities was non-linear. The antioxidant capacities against all three reactive oxygen species of the fruit pulp from one white açaí variety were very low. The phenolic compounds in purple açaí fruit pulp were identified by high-performance liquid chromatography-mass spectrometry, and the two major anthocyanins, cyanidin-3-glucoside and cyanidin-3-rutinoside, were quantified by high-performance liquid chromatography-visible spectrometry. The contributions of the anthocyanins to the overall antioxidant capacities of the fruit were estimated to be only approximately 10%. Obviously, compounds not yet identified

    Anthocyanin and polyphenolic compounds present in açai (Euterpe oleracea Mart.) were determined and their respective contribution to the overall antioxidant capacity established. Color stability of açai anthocyanins against hydrogen peroxide (0 and 30 mmol/L) over a range of temperatures (10-30 degrees C) was also determined and compared to common anthocyanin sources. Additionally, stability in a model beverage system was evaluated in the presence of ascorbic acid and naturally occurring polyphenolic cofactors. Cyanidin 3-glucoside (1040 mg/L) was the predominant anthocyanin in açai and correlated to antioxidant content, while 16 other polyphenolics were detected from 4 to 212 mg/L. Red grape anthocyanins were most stable in the presence of hydrogen peroxide, while açai and pigments rich in acylated anthocyanins displayed lower color stability in a temperature-dependent manner. In the presence of ascorbic acid, acylated anthocyanin sources generally had increased color stability. Açai was recognized for its functional properties for use in food and nutraceutical products.



    Açai (Euterpe oleracea Mart.) polyphenolics in their glycoside and aglycone forms induce apoptosis of HL-60 leukemia cells. Del Pozo-Insfran D, et al. 1: J Agric Food Chem. 2006 Feb 22;54(4):1222-9. Department of Food Science and Human Nutrition, University of Florida, P.O. Box 110370, Gainesville, Florida 32611-0370, USA.

    The effects of açai polyphenolics on the antiproliferation and induction of apoptosis in HL-60 human leukemia cells were investigated. Interactions between anthocyanins and non-anthocyanin-polyphenolics in both their glycosidic and their aglycone forms were also investigated to determine additive or nonadditive responses. Polyphenolic fractions at 0.17-10.7 microM were found to reduce cell proliferation from 56 to 86% likely due to caspase-3 activation (apoptosis). Anthocyanin and polyphenolic fractions were nonadditive in their contribution to the cell antiproliferation activity. At equimolar concentrations, the glycosidic forms of phenolic acids and flavonoids induced a higher magnitude of change in cell parameters (proliferation and apoptosis) than their respective aglycone forms, while the opposite trend was observed for anthocyanin aglycones. This study demonstrated that açai offers a rich source of bioactive polyphenolics and confirmed the importance of investigating whole food systems when evaluating the potential health benefits of individual phytochemical compounds.

    In vitro and in vivo antioxidant and anti-inflammatory capacities of an antioxidant-rich fruit and berry juice blend. Results of a pilot and randomized, double-blinded, placebo-controlled, crossover study. Jensen GS,et al. , J Agric Food Chem. 2008 Sep 24;56(1Cool:8326-33. Holger NIS Inc601 13th Avenue N.E., Calgary, Alberta, Canada T2E 1C7.

    This study investigated the in vitro and in vivo antioxidant and anti-inflammatory properties of a juice blend (JB), MonaVie Active, containing a mixture of fruits and berries with known antioxidant activity, including acai, a palm fruit, as the predominant ingredient. The phytochemical antioxidants in the JB are primarily in the form of anthocyanins, predominantly cyanidin 3-rutoside, cyanidin 3-diglycoside, and cyanidin 3-glucoside. The cell-based antioxidant protection of erythrocytes (CAP-e) assay demonstrated that antioxidants in the JB penetrated and protected cells from oxidative damage ( p < 0.001), whereas polymorphonuclear cells showed reduced formation of reactive oxygen species ( p < 0.003) and reduced migration toward three different pro-inflammatory chemoattractants: fmlp ( p < 0.001), leukotriene B4 ( p < 0.05), and IL-8 ( p < 0.03). A randomized, double-blinded, placebo-controlled, crossover trial with 12 healthy subjects examined the JB's antioxidant activity in vivo. Blood samples at baseline, 1 h, and 2 h following consumption of the JB or placebo were tested for antioxidant capacity using several antioxidant assays and the TBARS assay, a measure of lipid peroxidation. A within subject comparison showed an increase in serum antioxidants at 1 h ( p < 0.03) and 2 h ( p < 0.015), as well as inhibition of lipid peroxidation at 2 h ( p < 0.01) postconsumption.



    Pharmacokinetics of anthocyanins and antioxidant effects after the consumption of anthocyanin-rich acai juice and pulp (Euterpe oleracea Mart.) in human healthy volunteers.Mertens-Talcott SU, et al. J Agric Food Chem. 2008 Sep 10;56(17):7796-802. Department of Veterinary Physiology and Pharmacology, Texas A&M University, College Station, Texas 77843, USA.

    The acai berry is the fruit of the acai palm and is traditionally consumed in Brazil but has gained popularity abroad as a food and functional ingredient, yet little information exists on its health effect in humans. This study was performed as an acute four-way crossover clinical trial with acai pulp and clarified acai juice compared to applesauce and a non-antioxidant beverage as controls. Healthy volunteers (12) were dosed at 7 mL/kg of body weight after a washout phase and overnight fast, and plasma was repeatedly sampled over 12 h and urine over 24 h after consumption. Noncompartmental pharmacokinetic analysis of total anthocyanins quantified as cyanidin-3-O-glucoside showed Cmax values of 2321 and 1138 ng/L at t max times of 2.2 and 2.0 h, and AUC last values of 8568 and 3314 ng h L(-1) for pulp and juice, respectively. Nonlinear mixed effect modeling identified dose volume as a significant predictor of relative oral bioavailability in a negative nonlinear relationship for acai pulp and juice. Plasma antioxidant capacity was significantly increased by the acai pulp and applesauce. Individual increases in plasma antioxidant capacity of up to 2.3- and 3-fold for acai juice and pulp, respectively were observed. The antioxidant capacity in urine, generation of reactive oxygen species, and uric acid concentrations in plasma were not significantly altered by the treatments. Results demonstrate the absorption and antioxidant effects of anthocyanins in acai in plasma in an acute human consumption trial.
