The potential role of thiamine (vitamin B1) in diabetic complications.
Benfotiamine is a fat-soluble analog of Thiamine, and I know from blood tests that one capsule a day raised my level from marginally deficient to high-normal. Three capsules raised it to more than twice normal, which my Neurologist did not like.
My problem is peripheral neuropathy, likely a result of now-controlled type II diabetes. I have been on a low-carb, low-glycemic diet since 2005, but only managed to lose about 10 pounds in the first few months, down to about 235. Then last August 1 my wife and I joined the Jewish Community Center. I discovered that although I could not safely either run or “power walk” outdoors with my numb feet, I COULD walk on a treadmill because I could keep my balance by holding the frame.
I started slow, but gradually walked faster, longer, and at a progressively greater incline, until today I walk 2.7 miles daily in 35 minutes, at an incline of 12. And since May, I do this after 30 minutes on an “Arc Trainer”. Combined with a little weight training, I work off almost 1000 calories daily, according to the machines. My weight is down to 175, and I have had to drop one hypertension drug and reduce another, and switch to a gentler diuretic.
My A1c is normal, and my glucose averages under 100, morning and night. I do depend on Zocor to keep cholesterol under control, and I still take 150 mg of benfotiamine daily, just in case it helps. I THINK that I am regaining some feeling in my feet and lower legs, but my toes are still numb. I will find out in a few months, when I next see my neurologist.
I have discovered that most, if not all, “diabetic” shoes are a ripoff. To qualify, they need only a large enough toe box and a padded, but easily damaged or worn out lining. They do NOT offer either the support or the shock absorption that I badly needed for my activities, although I do still need the "accommodative inserts" that are custom fitted. I just put the inserts into high-quality running shoes (Nike Structure II) that have never caused a blister.
