Brief Summary:
The study will evaluate the effects of resveratrol/leucine and resveratrol/HMB for their ability to control glucose levels in persons without diabetes but with impaired fasting glucose. Secondary assessments will examine the effect of these nutritional supplements versus placebo on inflammation, fasting lipids, HbA1C, and fructosamine, longer term metabolic markers of risk in diabetes.
Detailed Description:
This will be a 28-day randomized controlled trial of the effects of a nutraceutical preparation on glycemic control in non-diabetic individuals with impaired glucose tolerance (IGT). IGT will be defined by American Diabetes Association criteria, as outlined in the list of inclusion and exclusion criteria (copy attached). There will be two active treatment arms and a placebo arm (3 arms total, n=12 completed subjects per arm). Following screening for inclusion/exclusion criteria and obtaining informed consent, subjects will be enrolled in the study and provided instructions to maintain their usual dietary pattern and physical activity level. If recent physical examination and medical history are not available; H\&P will be conducted and recorded for each enrolled subject. Subjects will be instructed to follow a 12-hour fast starting on day -1, and on the morning of day 0 fasting blood is drawn for analyses indicated below and the supplements are distributed. Supplements are distributed using a blinding protocol and a variable, known pill allotment in order to assess compliance via standard pill counts. Pill bottles and all unused supplements are returned at seven day intervals, with new supplies being distributed at that time. Fasting blood samples are obtained on days 0, 7, 14 and 28. Samples from each day are analyzed for glucose and insulin. Samples from days 0, 14 and 28 are also analyzed for fructosamine, C-peptide, glucagon and F2-isoprostanes. A75 g oral glucose tolerance test administered on days 0 and 28.
