What @jakedduck1 says... Also remember, just because something is a "supplement" instead of a prescription drug does not make it safe - or effective. And not all supplement, which are not subject to FDA testing, contain what the label says. So if you plan to add something, consider a single ingredient that others here have found helpful over time (not just "I think I slept better" for a few days - that can be the placebo effect.)
First, if you have an adverse reaction, you know what is causing it.
Second, when supplement makers "dump" tons of ingredients into one pill, it is often a ploy - they know what the "in" things being marketed right now are, so put a little of each, plus a bunch of other good-sounding stuff in to entice you into thinking you can get it "all for one price" when what you are most likely getting is a lot of the cheap ingredients and just a pittance of the ones advertised.
Let's take NeuraZenx for example -
Each dose (2 tablets) includes WELL OVER the recommended daily allowances for Vitamin D, Vitamins B2, B6, B12 & Folate - which at BEST gives you expensive urine, and at WORST can cause an overdose of one or more - especially when added to your daily diet and any other supplements you take.
Now let's look at that long list of "other good stuff" and see what WebMD, Mayo and others say about possible effectiveness for neuropathy, and what is a therapeutic dose.

For a therapeutic dose of: 2 capsules have: Good for Neuropathy:
Turmeric root (curcumin) 600-900mg 100mg unknown
Alpha-lipoic acid 600-1800mg 600mg yes
Acetyl-l Carnitine 1500-3000mg 100mg yes
Benfotiamine 150-600mg 200mg yes
N Acetyl-cysteine 600-1200mg 10mg unknown
L Arginine 1500-2400mg 25mg unknown
All the rest are of unknown benefit to neuropathy, and extremely tiny amounts...
You get the idea.
I say talk to @johnbishop and others here about what they may have found before you spend money.
And that's my "Number crunching" for today
