Recently, the açaí berry has been marketed as a dietary supplement. Companies sell açaí berry products in the form of tablets, juice, smoothies, instant drink powders, and whole fruit.

Marketers of these products make claims that açaí provides increased energy levels, improved sexual performance, improved digestion, detoxification, high fiber content, improved skin appearance, improved heart health, improved sleep, and reduction of cholesterol levels. Quackwatch noted that "açaí juice has only middling levels of antioxidants—less than that of Concord grape, blueberry, and black cherry juices, but more than cranberry, orange, and apple juices."

Furthermore, the extent to which polyphenols as dietary antioxidants may promote health is doubtful. No credible evidence indicates any antioxidant role for polyphenols in vivo, but rather in minute concentrations, they may affect cell-to-cell signaling, receptor sensitivity, inflammatory enzyme activity or gene regulation. Specifically, there is no scientific evidence that açaí consumption affects body weight or could promote weight loss.

According to the Washington, D.C. based Center for Science in the Public Interest (CSPI) thousands of consumers have had trouble stopping recurrent charges on their credit cards when they cancel free trials of açai-based products. Even some web sites purporting to warn about açai-related scams are themselves perpetrating scams. Apparently false claims include reversal of diabetes and other chronic illnesses, as well as expanding size of the penis and increasing men's sexual virility and sexual attractiveness to women.

As of March 2009, there are no scientifically controlled studies backing up any of these claims. According to ABC News correspondent Susan Donaldson, these products have not been evaluated (in the United States) by the FDA, and their efficacy is questionable. In late 2008, lawyers for The Oprah Winfrey Show began investigating alleged statements from supplement manufacturers who suggested that frequent Oprah guest Dr. Mehmet Oz had recommended their product or açai in general for weight loss.

A powdered preparation of freeze-dried açaí fruit pulp and skin (Opti-açaí, K2A, Inc.) was reported to contain (per 100 g of dry powder) 533.9 calories, 52.2 g carbohydrates, 8.1 g protein, and 32.5 g total fat. The carbohydrate portion included 44.2 g of dietary fiber. The powder was also shown to contain (per 100 g): negligible vitamin C, 260 mg calcium, 4.4 mg iron, and 1002 U vitamin A, as well as aspartic acid and glutamic acid; the amino acid content was 7.59% of total dry weight.

The fat content of açaí consists of oleic acid (56.2% of total fats), palmitic acid (24.1%), and linoleic acid (12.5%). Açaí also contains beta-sitosterol (78–91% of total sterols). The oil compartments in açaí fruit contain polyphenols such as procyanidin oligomers and vanillic acid, syringic acid, p-hydroxybenzoic acid, protocatechuic acid, and ferulic acid, which were shown to degrade substantially during storage or exposure to heat.

A comparative analysis from in vitro studies reported that açaí has intermediate polyphenol content and antioxidant potency among 11 varieties of frozen juice pulps, scoring lower than acerola, mango, strawberry, and grapes.

A powdered preparation of freeze-dried açaí fruit pulp and skin was shown to contain anthocyanins (3.19 mg/g); however, anthocyanins accounted for only about 10% of the overall antioxidant capacity in vitro. The powdered preparation was also reported to contain twelve flavonoid-like compounds, including homoorientin, orientin, taxifolin, deoxyhexose, isovitexin, scoparin, as well as proanthocyanidins (12.89 mg/g), and low levels of resveratrol (1.1 µg/g).[17] A study on another different freeze-dried acai product (Opti-Acai) reported that the formulation contained much lower levels of anthocyanins, proanthocyanadins, and other polyphenol compounds as compared with blueberries and other antioxidant-rich fruits.

In an in vitro study of different açaí varieties for their antioxidant capacity, a white one displayed no antioxidant activity against different oxygen radicals, whereas the purple variety most often used commercially had antioxidant activity against peroxyl radicals and to a lesser extent peroxynitrite but little activity against hydroxyl radicals.

Freeze-dried açaí powder was found to have antioxidant activity in vitro against superoxide (1614 units/g) and peroxyl radicals (1027 µmol TE/g) and mild activity for peroxynitrite and hydroxyl radicals. The powder was reported to inhibit hydrogen peroxide-induced oxidation in neutrophils, and to have a slight stimulatory effect on nitric oxide production by lipopolysaccharide-stimulated macrophages in vitro. These results, however, apply only to in vitro conditions and remain unknown for whether they are physiologically relevant. Rather, more subtle, non-antioxidant roles in vivo are likely.

Extracts of açaí seeds were reported to have antioxidant capacity in vitro against peroxyl radicals, similar to the antioxidant capacity of the pulp, with higher antioxidant capacity against peroxynitrite and hydroxyl radicals. [edit] Antioxidant potential of açaí juice

When three commercially available juice mixes containing unspecified percentages of açaí juice were compared for in vitro antioxidant capacity against red wine, tea, six types of pure fruit juice, and pomegranate juice, the average antioxidant capacity was ranked lower than that of pomegranate juice, Concord grape juice, blueberry juice, and red wine. The average was roughly equivalent to that of black cherry or cranberry juice, and was higher than that of orange juice, apple juice, and tea.

A study in 12 healthy fasted human volunteers demonstrated that blood antioxidant capacity was increased within two hours after consumption of a commercial açaí juice beverage or applesauce, but did not investigate any physiological effect of these supposed antioxidants. The generation of reactive oxygen species was not significantly affected by acai juice consumption.

Although açaí is notable for its potentially rich polyphenol content, the anthocyanins of this fruit likely have relevance to antioxidant capacity only in vitro. This occurs because phenolic antioxidant properties of açaí are unlikely to be conserved after the fruit is consumed, as interpreted by the Linus Pauling Institute which states that dietary anthocyanins and other flavonoids have little or no direct antioxidant food value following digestion. Not like controlled test tube conditions, the fate of anthocyanins in vivo shows they are poorly conserved (less than 5%), with most of what is absorbed existing as chemically-modified metabolites destined for rapid excretion.

The increase in antioxidant capacity of blood seen after consumption of anthocyanin-rich foods like açaí is not caused directly by the anthocyanins or other polyphenols, but most likely results from increased uric acid levels derived from polyphenol metabolism. According to Frei, "we can now follow the activity of flavonoids in the body, and one thing that is clear is that the body sees them as foreign compounds and is trying to get rid of them."

Other research

Freeze-dried açaí powder was shown to have mild inhibitory effects on cyclooxygenase enzymes COX-1 and COX-2, and chemically-extracted polyphenolic-rich fractions from açaí were reported to reduce the proliferation of HL-60 (experimental leukemia) cells in vitro. In vitro anti-proliferative effects were also observed with extracts from açaí pulp oil. In a study of rats fed a high cholesterol diet, supplemental feeding with dry açaí pulp reduced blood levels of total and non-high-density lipoprotein cholesterol and superoxide dismutase activity.

Orally-administered açaí has been tested as a contrast agent for magnetic resonance imaging of the gastrointestinal system. Its anthocyanins have also been characterized for stability as a natural food coloring agent.
