Lack of toxicity of optimal concentrations of fermented blueberry extract and components. 3 T3-L1 pre-adipocytes were seeded at a density of 2 × 10⁴ cells, cultured to 100% confluence and treated for 7 days with treatments as described above. Cytotoxicity was measured by LDH leakage. Medium LDH activity was expressed as a percentage of total enzyme activity (medium + lysate). The results are shown as the mean ± SEM. Significant differences compared to DMSO vehicle control were assessed by one way ANOVA; post hoc analysis with Dunnett’s multiple comparison test. *** Denotes statistically significant from vehicle control (p < 0.001)
