What the evidence says
Mostly mechanism / observational
Most Acai studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from medium-quality randomised trials published 2008–2020 with a typical study size of 30 participants.

In plain English: Findings from this small pilot study provide a weak indication that the selected dose of açaí polyphenols may be beneficial in metabolic syndrome as only two biomarkers for inflammation and oxidative stress were improved over 12 weeks.

Randomized, double-blind, placebo-controlled pilot in 37 metabolic-syndrome patients over 12 weeks
Plasma IFN-γ and urinary 8-isoprostane decreased significantly vs placebo
NO significant change in any lipid- or glucose-metabolism biomarker
In plain English: The results indicated a positive impact of regular consumption of açaí and juçara juices on the HDL-c levels, as well as on the antioxidant enzyme activities, which may contribute to cardiovascular health.

Randomized crossover in 30 healthy adults, 200 mL/day for 4 weeks
HDL-c rose 7.7% and antioxidant enzymes (catalase, GPx) increased vs baseline
No significant intergroup differences for any outcome (P > 0.05)
