I have studied nutrition for many years. I have discovered that if I take Vitamin B-12 Subliminal (under the tongue) - it goes directly to the brain and blood vessels. After 50 years old, we only use 2% of what we take orally, but 98% of what we take subliminally. I also take a high dose Vitamin B tablet (the B vitamins work in conjunction with each other.) When I do this, I do not have the pains in my feet and hands. I read that this vitamin can repair all the nerves in the body in 30 days. I can even remember why I went into the other room when I take it. And it makes me alert and not sleepy and napping all the time. I hope you post this. It is really helpful to me and may help others. It is worth a 30 day try. (I had to ask my pharmacist for it because it wasn't out on the counter).

I agree with you, I also take B-12 that way and immediately after I feel better and not so tired. Others should try it!

If the "researchers hope that more research will show how much of the inflammation is caused by high blood sugar versus other causes," then one would assume they studied diabetic subjects with high blood sugar.
A classic problem with such persons are gum infections, a likely cause of high white blood counts.
Have seen no reports that diabetics with well-controlled blood glucose levels are commonly subject to infections. Moreover, infections should not be lumped into the general "inflammation" category, so perhaps the write-up has gone awry.
And I agree with the above posters on the subject of B-12.

If I were a thin "Type 2" diabetic, I would get antibody testing (to detect autoimmune Type 1 diabetes) to make sure I was not misdiagnosed.

Sublingual (under the tongue)treatments give faster results due to more direct bloodstream absorption.
