Compositions for diabetes

摘要

The present invention provides a composition for improving glucose tolerance to patients having diabetic hyperglycemia and people having pre-diabetes, i.e., abnormal glucose tolerance. The composition helps control the blood glucose level, prevents diabetic complications, and can be administered over a long term due to its high safety. The composition containing a coenzyme Q, in particular, a reduced coenzyme Q₁₀, as the main component improves the impaired glucose tolerance of diabetes patients, satisfactorily controls the blood glucose level, and decreases the blood glycosylated hemoglobin level.
