Welcome Paul,
There are many many threads/posts in the
Peripheral Neuropathy forum about Neuropathy Support Formula which you can find by using the search function.
My own opinion about it is that while not a total scam, it's overpriced for what's in it, and its promises may be overstated.
Everyone's PN (including diabetics) is different, so there is no one-size-fits-all formula or treatment. There are recommended tests that you should get (if you haven't already) like B12, magnesium and a few others I'm not recalling off the top of my head, but they're all talked about a lot in the forum. Then there are many supplements depending on what
you need,
some of which are in the Neuropathy Support Formula (though perhaps not in the best ratio for
you), that can be gotten separately for much less, and tailored to
your specific needs.
