The Claim
Vitamin D deficiency is associated with an increased risk of developing type 2 diabetes, and this association is mediated by impaired insulin secretion from pancreatic beta cells and reduced insulin sensitivity due to calcitriol's modulation of genes involved in glucose metabolism.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Low levels of vitamin D are linked to a higher chance of developing type 2 diabetes, as vitamin D influences the function of insulin-producing cells and the body's response to insulin.
See the scientific wording
Vitamin D deficiency is associated with an increased risk of developing type 2 diabetes, potentially through impaired insulin secretion from pancreatic beta cells and reduced insulin sensitivity, as calcitriol modulates genes involved in glucose metabolism.
Without enough vitamin D, the pancreas cannot release insulin properly because calcium inside beta cells doesn't rise enough to trigger insulin release, and the body's muscles and fat cells don't respond well to insulin because key genes for glucose uptake are not turned on. This causes blood sugar to stay high and leads to type 2 diabetes.
What the research says
1 studyThis study says vitamin D helps your body manage blood sugar, and not having enough of it might make it harder for your body to use insulin properly, which can lead to type 2 diabetes.
