I have been using bone-joint formulas for 5 yrs. or so, and finally found one that seems to work the best (so far). That one is ULITMATE JOINT REPAIR FORMULA (DrGooberman.com). It's expensive in my opinion, so I've decided to try (msm-msm.com): MSM powder, GS powder, with buffered vit C powder; and recently added 700 mg of magnesium powder per day. I'm experiencing more joint pain now than I was with the capsules from Gubberman. What am I missing? Chrondrotin, essential fatty acid complex, Bromelin, Boswelin Serata Extract,Tumeric, Ginger, Manganese??? I'm 57 yrs. old and damaged my joints a lot when I was young.
