I came upon this supplement by chance while talking to my boss about his lumbar spondylosis treatment.  He mentioned that his doctor recommended taking it for the pain and inflammation.  I did some research on it, and found it is also used to treat fibro, and discovered that the distilled version is better - no additives and is pure.  The RDA is 1gram (1,000 mg) per day.  I take the capsule, not powder.  I started taking it four weeks ago, and it has made a big difference.  It hasn't eliminated the pain, but it's minimized a more manageable.  I have stopped taking the cyclobenzaprine and naproxen.  I am not on any other fibro meds.  The last straw was when the neurologist prescribed Lyrica, which I did not want to take.  I also take 4000 in of D3 daily, along with calcium citrate with magnesium.  

Has anyone else heard of/tried it?  If so, I'm interested in others' experiences.

I also have cervical spondylosis which causes excruciating nerve pain down my right neck, shoulder, shoulder blade, middle of my back, arm and hand, and had also recently started on my left side.  It feels like it's on fire when it starts acting up.  I MSM has also helped with this, and I feel I also have a little more energy to keep more active, and am able to do my PT at home to strengthen my supporting muscles.
