## Abstract

Plants from the Zingiberaceae family, particularly Zingiber officinale, Curcuma longa, and Alpinia galanga, are rich sources of bioactive compounds with documented antidiabetic and anti-inflammatory properties. This review summarizes current evidence on their phytochemical profiles and pathways relevant to metabolic regulation. Key compounds, including gingerols, shogaols, curcuminoids, and phenylpropanoids, support glucose homeostasis by enhancing insulin sensitivity, promoting Glucose Transporter Type 4 (GLUT4)-mediated glucose uptake, improving β-cell function, and modulating metabolic signaling pathways such as PI3K/Akt, AMPK, PPARγ, and NF-κB. Their potent antioxidant and anti-inflammatory activities further reduce oxidative stress and chronic low-grade inflammation, both central to the progression of type 2 diabetes and its complications. Evidence from selected clinical and experimental studies suggests that dietary supplementation with whole-rhizome preparations or standardized extracts (including formulation-enhanced products) may improve fasting blood glucose (FBG), glycated hemoglobin (HbA1c), lipid metabolism, and oxidative stress markers. Recent advances in delivery systems, including nanoemulsions, liposomes, and curcumin–piperine complexes, substantially enhance the bioavailability of poorly soluble phytochemicals, strengthening their therapeutic potential. Overall, Zingiberaceae plants emerge as promising natural supplements in nutritional and pharmacological strategies targeting diabetes. Further clinical research is required to refine dosage, confirm long-term efficacy, and support their integration into evidence-based metabolic interventions.
