L-Glu and acai berry extract effects on cellular ROS levels. SH-SY5Y cells were treated with L-Glu (A), acai berry extracts (B), or 100 mM L-Glu with different concentrations of acai berry extracts (C,D), and the levels of ROS quantified using a DCFDA assay. Hydrogen peroxide (H₂O₂) at 500 μM for 30 min was used as a positive control for ROS generation. Data values were analyzed using one-way ANOVA with Tukey’s multiple comparisons and presented as means ± SEM for three separate experiments at each concentration (n = 3 per experiment). For significance marked on Figures: * p < 0.05, ** p < 0.01, and **** p < 0.0001 vs. control in the absence of L-Glu, acai berry extracts and H₂O₂. &&&& p < 0.0001 vs. L-Glu alone.
