Brief Summary
Currently, the incidence of diabetes mellitus is increasing worldwide. People with prediabetes have higher risk to develop diabetes mellitus type 2. Several studies have proven that Zinc and Chromium are minerals that contribute to decreasing the level of blood glucose and insulin resistance. In addition, vitamin C also contributes in decreasing Fasting Blood Glucose (FBG) and Hemoglobin A1c (HbA1c). However, the eficacy of a combined zinc, chromium, vitamin C, and copper (ZCC) in decreasing blood glucose in prediabetic people has never been performed. The primary objective of this study is to investigate the effect of a combination of ZCC supplementation with standard healthy lifestyle counseling in improving glucose profile \[Fasting Blood Glucose (FBG), 2-hour Oral Glucose Tolerance Test (OGTT), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR)\] from prediabetes to normal or reducing the risk of progression from prediabetes to Type 2-Diabetes Mellitus (T2DM) compared to placebo with standard healthy lifestyle intervention.
