I have been using 98 Alive for a couple of months. As a 77 year old Yoga Teacher, I have my share of muscle or joint pain. I have never been as excited or so impressed with a product that not only takes away the pain but does it in a matter of minutes. Guess what? It doesn't come back. I have recommended this product to several of my students with great success. This is a natural product which makes it even better. No side affects!! You wan't be disappointed if you try it!
