N2 - 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 açai, 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.
