Initial clinical trial results, published in a 2012 PLOS One paper, reported that two doses of BCG spaced four weeks apart led to reductions in autoreactive T cells, an increase in Tregs and what turned out to be a transient increase in insulin production. But by the end of that short, 20-week trial, there was no reduction in HbA1c, the established measure of blood sugar levels over time. An extension and expansion of that trial with long term follow-up, the current results are based on data from 282 human study participants – 52 with type 1 diabetes who participated in the BCG clinical trials and 230 who contributed blood samples for mechanistic studies.
If I could only prescribe one supplement for a diabetes patient, I would prescribe R-alpha-lipoic acid. Alpha-lipoic acid has numerous benefits to the diabetic patient. It is a water- and fat-soluble antioxidant and has been shown to protect patients with fatty liver from liver disease progression. It can help reduce insulin resistance and has been shown to protect people with diabetes from developing complications in their nerves, eyes, and kidneys. R-ALA can prevent glycosylation of proteins, which reduces the A1C level. It is safe, although very rarely it can cause stomach upset. Alpha-lipoic acid is listed either as ALA or R-ALA. When listed as ALA, this means it contains two forms—the S isomer form and the R isomer form, in a 50:50 ratio. The key is to find a product that says it contains “R-ALA” instead of just “ALA.” A good daily working dose of R-ALA is 300 to 1,200 mg a day, which is the equivalent of 600 to 2,400 mg a day of regular ALA, if you buy a regular ALA listed product.
There are major barriers for widespread use of islet also-transplantation that can help people with type 1 diabetes. The shortage of islets from donors is a huge obstacle. The other obstacle is that this is still considered an experimental procedure and until the procedure is considered successful enough to be labeled therapeutic by the FDA instead of experimental, the costs of these transplants come from limited research funds.
According to studies, cinnamon may have a positive effect on the glycemic control and the lipid profile in patients with diabetes mellitus type 2. This is because it contains 18% polyphenol content in dry weight. This popular Indian spice can improve insulin sensitivity and blood glucose control. According to a study published in Journal Of The American Board Of Family Medicine, “cinnamon lowered HbA1C by 0.83% compared with standard medication alone lowering HbA1C  0.37%. Taking cinnamon could be useful for lowering serum HbA1C in type 2 diabetics with HbA1C >7.0 in addition to usual care.”

One easy way to increase your fat content and quit snacking is to begin your meal by eating an avocado. I and others I know have used this trick to easily quit snacking. Avocados protect you from one of the reasons some dietary research wrongly claims that high-fat diets are bad for you: the danger of gorging yourself on delicious, fatty foods. With plain avocados, there is little danger of gorging. Another danger is clogging your arteries and giving yourself heart disease. But it’s been amply shown that the blame for that falls squarely on trans fats, like margarine. If you see any product with the words “partially hydrogenated” or “hydrogenated” in the list of ingredients, put it back, it’s a trans fat. On the other hand, any fat that comes directly from an animal or plant is not a trans fat and can be safely consumed.
