Vitamin D Lower Diabetes Risk A recent study found that supplements of vitamin D may reduce risk factors for type 2 diabetes. Vitamin D can improve the function of insulin-producing cells in people with pre-diabetes. "The results showed that vitamin D supplements may help reduce a major risk in people with type 2 diabetes," said co-author Dr. Anastassios Pittas, an endocrinologist at Tufts University Medical Center in Boston, USA, recently. Type 2 diabetes, the most common form of diabetes, it has been mengidapi millions of Americans. This condition is characterized by high blood sugar levels resulting from low body's response to insulin, a chemical that removes sugar from the bloodstream and store it in the liver and muscles. Insulin is made in the pancreatic beta cells. To see if vitamin D could improve people's ability to handle blood sugar, researchers gave 92 adults pre-diabetes with supplements of vitamin D3 and calcium supplements. After four months, the blood of the participants were tested to determine some risk factors for diabetes. The steps of testing, including tests of hemoglobin A1C, an indicator of blood sugar levels from time to time, and beta-cell function tests, as reflected by how much insulin is released and how well the body responds to insulin. The researchers found vitamin D increased significantly in beta-cell function in adults pre-diabetes, according to results published in the American Journal of Clinical Nutrition. The group taking vitamin D also had higher levels of hemoglobin A1C slightly more profitable. Calcium had no effect on beta cell function, either alone or in combination with vitamin D. The results did not always indicate vitamin D will reduce the likelihood of diabetes. Because this study only measured the blood test results. "However, the important finding is the supplementation influence biology," said Dr.. Ian De Boer, a nephrologist at the University of Washington in Seattle who was not involved in this study. De Boer estimates in the study of vitamin D improve beta cell function between 15 and 30 percent. Previous research has explored the relationship between vitamin D and diabetes with mixed results. Several studies also showed people with low vitamin D levels may be at higher risk for diabetes. However, most research shows vitamin D supplements may help prevent diabetes.
