Just wanted to know the supplement that does the same as metforin? I've just been told i'm prediabetic after fasting glucose , then glucose intolerance and now they did a A1C at my primary care doctor. So i'm hoping that is what is behind the burning in the feet/lower legs and will be a reverse on the snf diagnosis as all other tests were normal ( nerve conduction )

Alpha Lipoic Acid and Benfotiamine are important.

There is not supplement exactly like metformin.

Metformin does several things in the body to control blood sugar.

One is that it stops the liver from making too much glucose, during fasting periods. I don't know a supplement that does this.

At times, some nutrient will be highlighted as equal to metformin, but that usually does not pan out in the long run.
For example for years d-chiro-inositol was suggested as doing this. Well it does work, in women with PCOS who are infertile, and when used "like" metformin it allows for ovulation to restart.
But it does not have the same "power" on blood sugar.

Lipoic acid will help alot. I'd suggest you use the new form,
Stabilized R-lipoic. It is more soluble and can work at much lower doses. Benfotiamine is good too.

here is the supplement thread:

I"m taking the alpha lipoic acid now but plan to switch to the stablized r-lipoic and when i do how many mgs a day is the norm? I've got benfotimine to start next week. What company or brands do you suggest for supplements. Thanks so much eb

The R-lipoic should work at 100mg a day.

To start with the Benfotiamine, I'd do 300mg a day in divided doses for at least two months.

I use Doctor's Best now for all my special supplements except B12.
I've found them better than NOW (for tryptophan) and
Theanine (Swanson's).

I've used the R-lipoic from them for several months now, and
always have used their Benfotiamine.

They are reasonably priced at iherb.com and Amazon now.

You order them on line ?
