I am not saying this will cure everything, but in MANY cases, it can make a dramatic difference. What am I talking about?
If you have any sort of issues with your body, start taking a good multivitamin/mineral supplement daily. Solgar is a good brand I use myself. A lot of issues in the body can be corrected or coaxed in a positive direction with a good multivit-mineral supplement.
The zinc could boost your immune system, the B-Vitamins could reduce stress which will in turn have a positive effect on other parts, Alpha Lipoic Acid or Chromium could regulate your sugar and so on. I have seen many people miraculously get better from many things by just making this small adjustment.
Why does it work? Because many people are deficient in certain minerals or vitamins. We eat badly, as simple as that. Also we get depleted of other things for a variety of factors.
Of course the best remedy is to combine this with working on your feet, however I highly recommend the above if you have any health issues.
