I dont have nearly as many back problems, but am taking lots of supplements so not sure if this is causing the benefits, but will keep taking
SPM Triple Pack
Helps with stiffness and muscle tightness . Works !!
The pain I had in my back and knees have subsided big time.
After taking these in differing doses - from 1 per day, to 2 per day, to 4 per day, each for a week or longer, I had no pain improvement. Everyone's pain is different and from different causes, so be aware that nothing works for everything.
