Chromium and Insulin Resistance

NCT00846248 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 75

Summary

Chromium is an essential nutrient for the maintenance of normal glucose tolerance and its deficiency causes insulin resistance. Chromium administration has also been shown in several studies to lower glucose and insulin levels in patients with type 2 diabetes. Accordingly, we propose to perform a placebo-controlled study of chromium picolinate administration in a cohort of non-obese, non-diabetic, insulin resistant subjects. These subjects will be randomized to 16 weeks of therapy with either 500 mcg twice a day of Chromium or placebo.

Interventions

DIETARY_SUPPLEMENT

Chromium

We will enroll non-obese, non-diabetic subjects with insulin resistance in a 16 week treatment program with 500 μg of chromium picolinate twice daily. Insulin action will be determined by insulin clamp and OGTT using deuterated glucose both before and after treatment. Subjects will be compared to a placebo-treated group.
