No, no diabetes. It is good for the nerves, diabetic or whatever so it is really good with the neuropathy with POTS. I do not have sm. fiber or peripheral neuropathy. It is good for the nerves that tell the muscles etc, to pump the blood. It has helped me with my POTS, just wanted to mention it. Maybe you can find a doctor that knows about supplements. Very good antioxident. Antioxidents are good for the nerves. Keeps them healthy. I take a good brand of Lipoic Supreme. Pills, not IV. I have two integrative MD's that tell me how much and how often to take, brand etc. I have a schedule of supplements. Three times a day I take them. MANY. I am improving.
