May lower blood sugar levels

A common herbal therapy for lowering blood sugar in those with type 2 diabetes is bilberries. According to experts, berries work similarly to some blood sugar-lowering drugs by preventing the digestion and absorption of carbohydrates in your gut. According to animal research, bilberries' anthocyanins may also promote the release of insulin, a hormone essential for transferring sugar from the blood into cells.

In comparison to a placebo, one study found that bilberry extract significantly lowered blood sugar levels in persons with type 2 diabetes. The amount of extract was equal to 50 grams of fresh bilberries. Another 8-week trial found that persons with metabolic syndrome—a group of disorders that raises your risk of type 2 diabetes, stroke, and heart disease—had higher levels of insulin secretion when they had fresh bilberries in their diet.
