I first came across Real Time at a Health Expo for a half marathon I was running. I run and train a lot for half marathons, marathon, and triathlons, which means I often have pain in my knees, back, or ankles when I've been training hard. I have bad reactions (swelling in my extremities) when I take too much NSAIDS, so finding Real Time was a blessing for me. After the first time I tried it, I was sold, and continued to use it and recommend it to my family and friends. I'm getting ready to put in a second order for my mom, who has arthritis. She says it helps her a lot...Very impressive!
