I have had a sore throat for over 40 years now.
Nothing seemed to help until I started on the vitamins in Rich VanK's methylation protocol. I was taking the Holistic health Neutrological Health Formula vitamins when I began noticing the improvement. That product has been replaced by new ALL in One formula that I have not tried yet. Holistic health products are available at
www.holistichealth.com.
If you decide to try the Holistic health Vitamins, start slowly. The label says to take six a day, but that would be a huge mistake for most of us. I was able to start at a half a tablet a day, but I know of others that needed to start at a much lower dose.
My sore throat is not completely gone, but it is much better than it has been for a very long time.
