About

The investigators will conduct a randomized, double-blind, placebo-controlled study to investigate the effects and tolerability of ice plant (Mesembryanthemum crystallinum) extract in patients with impaired fasting glucose for 12 weeks.

Full description

A previous animal study has indicated that ice plant (Mesembryanthemum crystallinum) extract (IPE) has a substantial effect on attenuating hyperglycemia and modulating gut microbiota composition in diabetic rats. Therefore, IPE might be a promising functional food for the prevention of diabetes. Therefore, the investigators will conduct a randomized, double-blind, placebo-controlled study to investigate the effects of IPE in patients with impaired fasting glucose for 12 weeks; the safety of the compound is also evaluated. The Investigators examine 75-g oral glucose tolerance test (OGTT) (120 minute glucose), 75-g OGTT incremental Area Under the Curve 0-120min, 75-g OGTT (0, 30, 60, 90 minute glucose), fasting insulin, Homeostasis Model Assessment for Insulin Resistance, Quantitative Insulin Sensitivity Check Index, HbA1c, lipid profile (total cholesterol, triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol) at baseline and after 12 weeks of intervention. One hundred adults were administered either 2,000 mg of IPE or a placebo each day for 12 weeks.
