Does Creatine Monohydrate Improve Blood Sugar Control?
Listening to the news recently, there’s a tremendous amount of buzz surrounding type 2 diabetes. Currently, statistics from the Center for Disease Control and Prevention(CDC) suggest that one in ten Americans has type 2 diabetes. A new report from the CDC notes that by 2050, a staggering one in three Americans will have type 2 diabetes in current trends continue.
The projected increase in the incidence of type 2 diabetes is largely tied to the rising obesity epidemic. Concern has been raised that the combination of the aging population along with the increased incidence of type 2 diabetes could bankrupt the Canadian healthcare system due to the enormous costs associated with treating this condition.
In the same report from the CDC, they cite statistics that a 58% reduction in the onset of type 2 diabetes can be achieved by a 5-7% weight reduction along with just 150 minutes of exercise per week.
A recent study published in the journal, Medicine and Science in Sports and Exercise (Gualano et al, 2010), investigated whether or not creatine supplementation has a beneficial effect on blood sugar control in patients with type 2 diabetes who engage in an exercise program.
The study included 25 participants who were randomized to take 5 mg/d of creatine or placebo for 12 weeks while they engaged in an exercise training program.
The primary outcome measure of this study was glycosylated hemoglobin (HbA1C). This is a test that doctors routinely order on patients with diabetes to measure the effectiveness of their long-term blood sugar control
The study found that creatine supplementation significantly reduced HbA1C levels:
“HBA1c was significantly reduced in the creatine group when compared to the placebo group (CR PRE: 7.4±0.7, POST: 6.4±0.4; PL PRE: 7.5±0.6, POST: 7.6±0.7; p=0.004; difference: -1.1%, 95% confidence interval: -1.9 to -0.4).”
The study authors concluded that creatine supplementation along with routine exercise significantly improved glycemic control in patients with type 2 diabetes (compared to exercise + placebo).
