Query: Worked for me!

I was recommended Vita Medica Glucosamine by my orthopedic surgeon for my knee. I have been taking it for about 3 month and have noticed a reduction in the swelling I used to get in the joint and along with chiropractic work on the joint I am feeling as good as I have in 10 years -- considering I have virtually no cartlidge left on the outside of the knee joint.Unlike other glocosamine supplements I have taken before, there is no stomach upset and no multiple doses per day. I simply take two tablets in the morning and go.
