I have been using the Advanced Nerve Support for about 2 1/2 weeks. So far it seems to be lessening the tingling sensations in my feet. It is a day to day thing, but I haven't been using it that long. In my experience, at least for me, I like to give any natural product at least 90 days to show positive results. It is my hope that it will be the case with this product. So far it has shown positive results, which frankly has surprised me.
