I work in a pharmacy and a customer came in today and we were talking about arthritis. She has osteo. Itold her I have RA. She goes to a DO here in town and he gave her a product called M2. He gets it from a place in NY I think. She said her insurance covered it. You put a drop under your tongue several times a day for a few weeks then cut back. Has anyone heard of this and used it? I thought I might contact this DR office and see if I can get more info. Pat52
