6 or 7 years ago I had given up most of my outdoor activities because of knee pain.
I had a dog crippled with arthrities, my Vet treated her with glucosamine and the results were amazing.
I started taking it myself.It worked. I’m 57 years old , climb, ski, hike, bike, and can even run again.
I still have a little knee pain if I push it to hard but nothing near what it used to be.
Give it a try.
