Metformin, Glucophage


Metformin is a biguanide anti-diabetic drug.

Metformin is used for the treatment of diabetes mellitus type 2, especially when it is concomitant with obesity and insulin resistance. It is also being used experimentally in polycystic ovarian syndrome (PCOS) and non-alcoholic steatohepatitis, two diseases that feature insulin resistance.

Metformin is the only anti-diabetic drug that has been proven to reduce the complications of diabetes.

Metformin is often prescribed to type 2 diabetes patients in combination with rosiglitazone, under the drug name Avandamet.

What's your next step?

The next step, after you have been diagnosed with a disease, is to find out what is the specific cause, and then choose supplements that address it. Phone consults are my specialty. Please call my at (239) 659-2684 to schedule a consultation.

The choice is yours

I recommend that you make an informed choice, and the goal of this web site is to provide you with the information to make a wise choice when it comes to your health and wellness.

As you can see, I don't sell any vitamins on this web site. There are thousands of vitamin stores that will sell you whatever vitamin you want, and many of them offer discounts.

If you are interested in some high-quality basic nutritional supplements, I recommend visiting the Store You will find my recommendations for a multiple, tasty chewable fiber wafers, high-potency probiotics, and fish oils.

Good luck in your journey towards health and wellness!!

Why don't you tell me what vitamins to take for this disease?

Unfortunately, that would be a clear violation of FDA regulations. Also, one of the most important aspect of naturopathy is: "Treat the person, not the disease". This is a profound statement, and many people have spent thousands of dollars on vitamins listed in books or web sites for a specific disease. This is what I call "vending machine medicine". It rarely works! The solution is to find a naturopathic physician, such as myself, to assist you.
