Reduce Your Diabetes Risk By Up To 76% By Paying Attention To This Vitamin

Vitamin D intake & metabolic health in America.

Vitamin D plays a key role in glucose metabolism and insulin secretion. As such, evidence suggests that this essential fat-soluble vitamin–or, more specifically, the amount you have in your body–impacts your likelihood of developing diabetes.

Considering 29% of U.S. adults2 are deficient in vitamin D and another 41% are insufficient, it’s entirely possible the link between vitamin D and diabetes is stronger than we fully understand.

In this review, researchers analyzed three different randomized controlled trials (RCTs) to see whether increasing vitamin D intake for an individual with prediabetes can effectively lower their risk of developing diabetes. Two of the RCTs tested vitamin D3 (aka cholecalciferol) intake–specifically, 20,000 IU weekly and 4,000 IU daily–while the third tested eldecalcitol (a vitamin D analog).

Their findings highlighted yet another health benefit of vitamin D. Overall, vitamin D intake was found to reduce the risk of diabetes by 15% in individuals with prediabetes. Additionally, it increased the likelihood of regressing to normal (i.e., healthy) glucose regulation by 30%.

How vitamin D sufficiency impacts diabetes risk.

Interestingly, within the group of test participants that increased their vitamin D3 intake (rather than eldecalcitol), those that maintained a vitamin D blood serum level of 50 ng/ml or higher (i.e., the truly optimal vitamin D level we should be aiming for, according to experts) during the three-year follow-up reduced their diabetes risk by a whopping 76% compared to participants that had serum levels of 20 to 29 ng/ml (i.e., clinical insufficiency).

These findings demonstrate that achieving and maintaining a healthy vitamin D status is a key factor for metabolic health. Evidence shows that a premium vitamin D3 supplement is the most effective way to ensure vitamin D sufficiency.
