There have been people who use quite a long list of supplements.
Some of their posts can only be found using the search function.
One was Wing42... and when people mention the stickies, usually that is what they are looking for:

Those 3 posts are what worked for him.

I tend to have people start off with the most common deficiencies and fix those first, then add in other things according to their symptom development and history. Some people have DNA damage and so supplements for them would cluster on DNA mitochondrial support. (mostly from toxins and drugs)

Others have diabetic or alcohol induced PN and ALA (or the new stabilized r-lipoic acid and benfotiamine would help more that that.

So therefore there is no one "list" that would be better for everyone, since there are so many types of PN.

For explanations of the various common supplements there is my supplement thread.

The subforum above has several posts now discussing the various supplements..this is its link:

Yes, R-lipoic is better absorbed, but you need to choose the STABILIZED form, which is also called NaRALA on the label.
Doctor's Best makes this. 100mg a day is often enough.

The old ALA used in high dose should be taken on an empty stomach...1/2 of it is not active. You can spend alot of money on this type, whereas the STABILIZED type is less expensive by far to use.

NAC doses are typically 600mg a day (up to 3 times a day if tolerated).

Flares seem to occur for everyone to some extent. The Weather can do it...with extreme lows when storms move in triggering pain. Some people with autoimmune issues have waxing and waning periods when their disease becomes more active, and then later on sleeps.
People with inflammatory types of PN can see improvement during flares with aspirin (in AlkaSeltzer form) or other NSAIDs.
Fish oil can help this type as well.
