For one, vitamin D3 is a critical hormone to balance the immune system. It allows the immune system to “see” better. To better differentiate what is repairable, not and foreign. Thus, it is my opinion that the body is less likely to attack damaged and altered cells. Less likely to initiate autoimmune diseases.

So, it reduces the chance that the immune system will attack cells altered by elevated blood sugar, chronic inflammation, or causing autoimmune disease that precipitates for example type I diabetes to begin with.

Also, less chance of forming atherosclerosis if both type I and type II diabetics. Then vitamin D3 helps you through it effects at optimal levels by its effect on your metabolism as I discussed in previous blog posting (

Resulting in losing weight and reversing the chronic inflammation. Or by preventing you from becoming obese and setting of this cascade in the first place. Prevention isn’t sexy. Until you have been ill often and/or chronically most don’t appreciate how good they have it.

Our body is a complex machine that needs proper care. Unfortunately, due to our food options and lack of insight into proper care we are more prone then ever to end up ill. The reason I wrote the book is to try to educate as best I could.

It only takes a sentence to list what I consider the optimal dose of vitamin D3. However, I believe it is critical you understand as much as you can about why, how and what about vitamin D3. What optimal dosing means.

That way if it doesn’t work for you or you have an issue you will be better able to identify that issue. Identify the issue and do something about it before it could potentially harm you. For example, though rare some manufacturers of vitamin D3 have miss labeled the dose.

Or you may be receiving excess and be unaware. Though I think the optimal dose is safe in most it is a much higher dose then the government RDA. Though closer to the RDA then a dose that could harm you there still are risks. Risks like with any substance.

So, in an abundance of caution as lawyers like to say and as doctors want to practice- do no harm that is my reasoning. My reasoning behind why I believe it is important you educate yourself as much as possible. So please bear with me as I try to explain vitamin D3’s effect on diabetes, in particular type II diabetes.

Type II diabetes is a bit more complex as multiple factors go into it and to me it is the posterchild of the results of suffering from suboptimal blood levels of vitamin D3. With suboptimal blood levels of vitamin D3 one has abnormal sleep, metabolism and immune function.

All contribute to developing obesity, chronic inflammation and sleep deprivation. All contributing to developing type II diabetes. As I describe in previous blog winter syndrome ( So, by taking optimal doses to obtain optimal blood levels gradually in most these issues will resolve.

Sleep will improve allowing the body to better heal itself. Appetite, metabolic rate and fat absorption will revert to a healthy state. Finally, immune function will become optimal for you. With the metabolic changes those who are obese will lose weight. Your gut will heal.

Thus, the chronic inflammation associated with it will also resolve. No guarantee it will reverse your type II diabetes, if you have it. Though with the positive changes to your body, over an extended period, do so and at the least it has a good chance of reducing the negative side effects of having it.

Yes, I am hedging but I don’t want to over promise. As I have seen optimal doses result in miraculous changes in some and in others less so. Still other they don’t seem to be able to absorb it so no effect. Vitamin D3 is in my opinion a huge component to your health.

But something as simple as inadequate levels of one other mineral, vitamin or nutrient can prevent it from doing so. That is why I advocate educating yourself as much as possible. Vitamin D3 supercharges your body requiring more and often optimal levels of these other substances. Without them it is like driving with the emergency brake on. More in next post.
