Official title

"A Randomized, Double Blinded, Placebo Controlled, Parallel Arm, Study to Evaluate the Improvement in Glycemic Control After Daily Administration of Chromium Picolinate and Biotin in Patients With Type 2 Diabetes Mellitus"

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of the proposed work is to assess the effects of a dietary supplement, containing chromium (600 mcg per day) provided by chromium picolinate and biotin (2 mg per day) on glycemic control in type 2 diabetes. Specifically, this study will assess whether use of the supplement will lower the post-prandial rise in blood glucose experienced after ingestion of a 75g carbohydrate load, relative to placebo, in type 2 diabetic patients. The study will also assess the chronic effects of supplementation over a 4-week period (relative to placebo) on fasting plasma levels of glucose, insulin, lipids and lipoproteins.
