A new study published in the Annals of Internal Medicine has discovered that vitamin D may be the cure for prediabetes, preventing it from evolving into full-blown diabetes.
The study, based on a review of three clinical trials, found that a higher intake of vitamin D through supplementation, or natural sunlight exposure, resulted in a 15% decrease in the occurrence of Type-2 diabetes in prediabetic adults. The meta-analysis showed that only 22.7% of prediabetic adults who received vitamin D went on to develop diabetes after three years, compared to 25% of those who received a placebo.
Optimizing vitamin D levels is essential for optimal health, but high-dose supplementation should only be done under the guidance of a medical professional, as it comes with risks if not properly executed. Vitamin K and magnesium can help the body better synthesize vitamin D at therapeutic doses. Vitamin D encourages the pancreas to produce more insulin, making it crucial for prediabetic and diabetic individuals to maintain optimal levels.
Natural sunlight is the best form of vitamin D intake, but supplements are still better than nothing.
The study participants were given 70 micrograms of vitamin D per day, seven times the government-recommended daily dosage. Although high levels of vitamin D can lead to kidney stones and damage due to increased calcium absorption from the gut, none of the trial participants experienced any health problems from the supplementation.
To supplement safely, it is recommended to properly take vitamin D supplements or to prime the skin with astaxanthin, a natural “sunscreen” nutrient, instead of using harmful, UV-blocking sunscreens.
The Vitamin D Council suggests that those who are at risk of vitamin D deficiency, such as older individuals, those with dark skin, and those who are obese, may require higher doses to maintain optimal health. Vitamin D is crucial for strong bones and teeth, a strong immune system, a healthy cardiovascular system, and proper brain function.
In conclusion, the study highlights the potential of vitamin D in preventing the progression of prediabetes to full-blown diabetes and the importance of maintaining optimal levels of this important nutrient.
