Sylvie, I personally trust Doctor's Best and Life Extension products the most. They both have similar suppliers on many of their products that can be researched. Only because I have personally seen good results from them. I personally think with some of the supplements in the beginning you need to go with a very high dose to see results. This way you can see an impact. it also takes time for the body to start soaking them in. Then you can taper down. The key thing also is knowing how to take certain supplements. Some supplements must be taken on an empty stomach at least an hour before eating for maximum effect. Some supplements are ingested better with a fatty meal, some supplements in combination with others, etc. it's a continual learning process. I always take R-Lipoic and Benfotiamine at the same time and get real good relief. If I had to give up all my supplements and keep 2 it would be those. Google the clinical trials on a lot of these things. You will find some have multiple examples of efficacy in trial. The studies on Benfotiamine, B12, Acetyl L-Carnitine and R-Lipoic Acid are quite numerous in regards to neuropathy pain relief.

I also marvel at how stress, lack of sleep and eating unclean are immediate triggers for this condition. Anytime i even flirt with cheating and having junk I pay almost instantly. It also reminds me that I was able to bring my pain down and how it could be much worse if I am not vigilant.
