Go outside intead!
I like the concept, however, I think it is more like taking vitamins. The benefits are in the real thing. I did not notice any change, in fact after a day and night of using the product I woke after a very restless night with a very stiff back that later got worse. I normally do not get backaches. Thinking it might be coincidence I used the product for the next three weeks. It did nothing for any aches and pain I had. I did not sleep any better. I always feel better outdoors digging in the dirt and walking barefoot. I suggest we all do that a few times a week and save your money.
