In addition, phlorotannins extracted from Ecklonia cava (E. cava) have shown positive effects on postprandial glycemic control in the obese population, i.e., they were able to significantly reduce the postprandial area under the glucose curve (AUC), lower fasting blood glucose levels, reduce fasting plasma insulin concentrations, improve the homeostasis model assessment of insulin resistance (HOMA-) IR) indices, and effectively reduce glycated hemoglobin (HbA1c) levels [89,90]. Here, INS is linked to Insulin resistance.
