This study followed 31 people, average age 62, with type 2 diabetes for at least five years, and elevated long-term average blood sugar levels. Participants wore a glucose monitor for 48 hours, and ate a standard meal before and after taking a placebo or 500 mg of ascorbic acid vitamin C twice per day.
While there was no change for placebo, those taking vitamin C saw a 36 percent drop in blood sugar levels after the meal, reducing elevated blood sugar time by nearly 3 hours per day. Over 24 hours, average glucose levels decreased to 156.6 mg per deciliter of blood (mg/dL) from 171 mg/dL before taking vitamin C.
Average systolic and diastolic blood pressure in the vitamin C group were also lower by 7 mmHg and 5 mmHg, respectively. Doctors said vitamin C could be a cheap, convenient, effective additional therapy to improve glycemic control.
