9. Insulin Regulation
Vitamin Ds ability to alter things like appetite and metabolism can also extend to better regulation of insulin.
Insulin is a hormone that is released when blood sugar levels increase. This in turn causes the body to absorb that sugar where it can then either be used or stored as fat. By controlling the release of insulin, vitamin D can give us more balance over our blood sugar and this in turn can help to prevent weight gain and control the symptoms of diabetes.
Specifically, vitamin D works its magic by increasing our insulin sensitivity and through that, it helps us to make more use of the sugar in our bodies.
