The beneficial effect on sugar metabolism of a food supplement based on plant extracts, zinc and chromium

Efficacy study of the food supplement based on Moradyn® (purple corn variety extract Zea mays L.), Gymnema, Zinc, and Chromium, commercial name “GLIKUR Advance” for the maintenance of normal carbohydrate metabolism through the reduction of slightly altered plasma glucose levels, as cardiovascular risk factors: single-center, controlled, randomized, parallel-group, double-blind clinical study.

Design outcomes

Primary

MeasureTime frame
Improvement in fasting plasma glucose levels measured using blood tests for fasting serum glucose levels, HbA1c, fasting serum insulin levels and HOMA Index at baseline (t0), 90 days of treatment (t2)

Secondary

MeasureTime frame
1. Beneficial effect on lipid metabolism measured using the determination of blood levels of total cholesterol (TC), Low-Density Lipoproteins (LDL-C) cholesterol, High-Density Lipoprotein (HDL-C) cholesterol, Triglycerides (TG) at baseline (t0), 90 days of treatment (t2) 2. Height/weight assessment to calculate BMI at baseline (t0), 90 days of treatment (t2) 3. Liver and kidney toxicity measured using blood tests for the biomarkers aspartate transaminase (AST or SGOT), alanine transaminase (ALT or SGPT), and creatinine at baseline (t0), 30 days of treatment (t1), 90 days of treatment (t2).
