Thank you for your valuable feedback, Elizabeth. I am glad your body responds to magnesium. Every mineral is important but for me it is the most important mineral as supplementing it made a huge difference in my overall well being. Vibration machine is a tech device that you can stand on it and it shakes the body in different speed and frequencies. It is originally developed for astronauts to keep the muscle mass in space as lack of gravity caused them to lose muscles. Since then commercial organization made it a product. I have been using one over a decade. I will write an article sharing my research and experience on vibration machines soon. Several email subscribers also asked me about it. Thank you for inspiration.
