Hyperglycemia, characterized by elevated blood glucose levels, is a significant health concern that affects millions of individuals worldwide. It has been associated with long-term complications affecting the cardiovascular, renal, and nervous systems. Beetroot juice (BRJ), rich in nitrates, betalains, and antioxidants, has gained attention for its potential role in mitigating hyperglycemia and improving insulin sensitivity. This review evaluates the available scientific evidence on the hypoglycemic effects of beetroot juice, explores its proposed mechanisms of action, and discusses its potential as a complementary therapy for diabetes management. By analyzing studies, we found that beetroot juice may help manage hyperglycemia by enhancing insulin sensitivity through its nitrate content, which converts to nitric oxide. Clinical evidence indicates it may lower fasting blood glucose and improve glycated hemoglobin A1c (HbA1c) levels, though results vary. While beetroot juice shows promise as a supplementary treatment for hyperglycemia, more research is needed to determine the optimal dosage, long-term effects, and interactions with other diabetes management strategies.
