Until the findings are reproduced consistently, and cinnamon has been show to provide a meaningful improvement in relevant measures, there is no persuasive evidence to suggest that cinnamon has potential as a useful treatment option. Drugs that work, work consistently and provide meaningful improvements in measures of the disease. Why doesn’t cinnamon work?  There may be an active ingredient, but it’s present in low concentrations, and varies in content between the different batches of cinnamon used in the different trials. In that case, the active ingredient needs to be standardized and possibly isolated, which would make it a drug treatment.  Or this could be yet another example of a supplement that looks promising in early studies, only to see the effect disappear as the trials get larger and control for bias more effectively.

Suppose your friend is diagnosed with type 2 diabetes, then works hard to lose 50 pounds. He takes himself off all his medications and his blood sugars are now normal. What would you say to him? Probably something like “Great job. You’re really taking care of yourself. Keep it up!” What you wouldn’t say is something like “You’re such a dirty, filthy liar. My doctor says this is a chronic and progressive disease so you must be lying ”. It seems perfectly obvious that diabetes reversed because your friend lost all that weight. And that’s the point. The disease is reversible.
The first step is to eliminate all sugar and refined starches from your diet. Sugar has no nutritional value and can therefore be eliminated. Starches are simply long chains of sugars. Highly refined starches such as flour or white rice are quickly broken down by digestion into glucose. This is quickly absorbed into the blood and raises blood sugar. For example, eating white bread increases blood sugars very quickly. Doesn’t it seem self-evident that we should avoid foods that raise blood sugars because they will eventually be absorbed into the body? The optimum strategy is to eat little or no refined carbohydrates.

Alternative: “The reason I use food-based supplements is because they most closely help correct what I see as the problem: The food we’re eating is lacking in nutrients,” DeLaney says. “If their vitamin D is low, it tells me all their fat-soluble vitamins are low.” She uses cod liver oil along with high-vitamin butter oil to restore these deficiencies.

Magnesium is a mineral found naturally in foods such as green leafy vegetables, nuts, seeds, and whole grains and in nutritional supplements. Magnesium is needed for more than 300 biochemical reactions. It helps regulate blood sugar levels and is needed for normal muscle and nerve function, heart rhythm, immune function, blood pressure, and for bone health.
Note that these medications used to treat type 2 diabetes are typically not used in pregnant or breastfeeding women. At present the only recommended way of controlling diabetes in women who are pregnant or breastfeeding is by diet, exercise, and insulin therapy. You should speak with your health-care professional if you are taking these medications, are considering becoming pregnant, or if you have become pregnant while taking these medications.
