Investigating the Impact of Açai (Euterpe oleracea) on Lipid Profile: A Comprehensive Systematic Review and Meta-Analysis.
This systematic review and meta-analysis assessed the impact of açaí consumption on lipid profile markers. Meta-analysis of 411 participants showed no significant effect of açaí on LDL-c, HDL-c, total cholesterol, and triglycerides, but a significant reduction in total lipids was observed. The evidence was rated as low/very low certainty.
An evidence-based systematic review of acai (Euterpe oleracea) by the Natural Standard Research Collaboration.
Systematic review of acai (Euterpe oleracea) by the Natural Standard Research Collaboration, consolidating safety and efficacy data from scientific literature. Includes analysis of clinical trials, expert opinion, history, pharmacology, interactions, adverse effects, and dosing.
Effects of acai supplementation (Euterpe precatoria Mart) on muscle recovery markers after jump protocol.
RCT evaluating the effects of acai supplementation on muscle recovery markers in 12 men over 21 days. Acai supplementation increased antioxidant capacity and promoted faster recovery of knee flexors' isometric peak torque compared to placebo.
Açaí (Euterpe oleracea Mart.) and juçara (Euterpe edulis Mart.) juices improved HDL-c levels and antioxidant defense of healthy adults in a 4-week randomized cross-over study.
A randomized cross-over study with 30 healthy adults evaluated the effects of açaí and juçara juice intake on fasting glucose, lipid profile, and oxidative stress biomarkers. Both juices increased HDL-c levels, and açaí juice significantly improved antioxidant enzyme activities, suggesting benefits for cardiovascular health.
Açaí (Euterpe oleracea Mart.) beverage consumption improves biomarkers for inflammation but not glucose- or lipid-metabolism in individuals with metabolic syndrome in a randomized, double-blinded, placebo-controlled clinical trial.
RCT of 37 individuals with metabolic syndrome consuming açaí beverage or placebo for 12 weeks. Açaí consumption significantly decreased plasma level of interferon gamma and urinary level of 8-isoprostane, indicating reduced inflammation, but did not significantly modify biomarkers for lipid- and glucose-metabolism.
Phase II Trial of Acai Juice Product in Biochemically Recurrent Prostate Cancer.
Phase II clinical trial of Acai Juice Product in 21 patients with biochemically recurrent prostate cancer. The study did not meet its primary endpoint of 50% PSA response, but PSA doubling time was lengthened in 71% of patients, suggesting potential effects on PSA stabilization.
Consumption of a flavonoid-rich açai meal is associated with acute improvements in vascular function and a reduction in total oxidative status in healthy overweight men.
RCT with 23 healthy overweight men assessing the acute effects of açai consumption on vascular function and oxidative stress. Açai improved vascular function and reduced oxidative status compared to a control smoothie, but increased postprandial insulin levels.
Consumption of açai (Euterpe oleracea Mart.) functional beverage reduces muscle stress and improves effort tolerance in elite athletes: a randomized controlled intervention study.
RCT analyzing the effect of an acai functional beverage on muscle and oxidative stress markers, cardiorespiratory responses, perceived exertion, and time-to-exhaustion during maximal treadmill running in 14 elite athletes. The beverage increased time to exhaustion, reduced perceived exertion, and enhanced cardiorespiratory responses, suggesting it may be a useful ergogenic aid.
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.
This study investigated the antioxidant and anti-inflammatory properties of MonaVie Active, a juice blend containing acai and other fruits. In vitro assays showed the juice blend protected cells from oxidative damage and reduced reactive oxygen species formation. A randomized, double-blinded, placebo-controlled, crossover trial with 12 healthy subjects demonstrated increased serum antioxidants and reduced lipid peroxidation following consumption.
Pharmacokinetics of anthocyanins and antioxidant effects after the consumption of anthocyanin-rich acai juice and pulp (Euterpe oleracea Mart.) in human healthy volunteers.
This acute four-way crossover clinical trial studied the pharmacokinetics and antioxidant effects of anthocyanins in acai pulp and juice compared to controls in 12 healthy volunteers. Plasma antioxidant capacity was significantly increased by acai pulp and juice, demonstrating absorption and antioxidant effects of anthocyanins in plasma.
Açai Berry Mitigates Parkinson’s Disease Progression Showing Dopaminergic Neuroprotection via Nrf2-HO1 Pathways
Animal study investigating the effects of Açai berry supplementation on Parkinson's disease progression. Açai berry reduced motor and non-motor symptoms, neuronal cell death, α-synuclein aggregation, and enhanced dopamine-related activities, suggesting neuroprotective effects via Nrf2-HO1 pathways.
A Preliminary Assessment of the Nutraceutical Potential of Acai Berry (Euterpe sp.) as a Potential Natural Treatment for Alzheimer’s Disease
The study assessed the nutraceutical potential of acai berry extracts for Alzheimer's disease treatment. Acai aqueous extract showed concentration-dependent inhibition of acetyl- and butyryl-cholinesterase enzymes, while both extracts demonstrated antioxidant capabilities, with the ethanolic extract being the most potent.
Screening for CYP3A4 inhibition and induction coupled to parallel artificial membrane permeability assay (PAMPA) for prediction of botanical-drug interactions: The case of açaí and maca.
In vitro study investigating the potential for botanical-drug interactions of açaí and maca extracts with CYP3A4-metabolized drugs. Açaí extract showed significant inhibition and induction effects on CYP3A4, suggesting potential interactions.
