Therapeutic Potential of Nutraceuticals in the Management of Diabetic Mellitus

Hyperglycaemia, a chronic metabolic disease caused by insufficient or resistant insulin, or both, is an indicator of diabetes mellitus. The prevalence of diabetes is rising worldwide, which has increased interest in complementary and alternative medicines, such as nutraceuticals, which may help manage the condition. Nutraceuticals are bioactive substances that go beyond simple nourishment to offer additional health advantages. They can be found in foods or dietary supplements. Numerous nutraceuticals, including vitamins, trace elements, omega-3 fatty acids, polyphenols, and flavonoids, have shown antidiabetic effects through mechanisms like increased glucose uptake, insulin sensitivity, antioxidant effects, and inhibition of absorption of carbohydrates. any studies have been conducted on the potential of certain compounds, such as resveratrol from grapes, berberine from different plants, and curcumin from turmeric, to control blood glucose levels and relieve the symptoms of diabetes-related conditions like neuropathy and cardiovascular disease. Nutraceuticals may help regulate insulin release, shield pancreatic β-cells from oxidative stress, and lessen inflammation, all of which are important factors in the development of diabetes and its consequences, according to clinical research and animal models. To validate their therapeutic role and determine optimal dosages, large-scale human trials are necessary to further investigate the safety and efficacy of nutraceuticals. This review emphasizes the role that nutraceuticals play in improving insulin sensitivity, glycaemic management, and lowering the risk of complications associated with diabetes mellitus. It also underlines the potential of these treatments as supplementary measures. Nutraceuticals show promise, but in the holistic care of diabetes, they should be used in conjunction with traditional medicines and lifestyle adjustments, not in substitution of them.
