I have very stiff joints in the morning or after rest

The most common reason for stiff joints in the morning is improper calcium utilization. First, calcium must be available. Despite what you might think or have been told to think by either the dairy association or most medical physicians, eating or drinking more cow milk is not going to solve your calcium issue. Calcium needs an acidic environment in order to be properly absorbed, which is why supplements such as calcium carbonate or oyster shell calcium are such poor choices. The acidity primarily comes from proper stomach acid (HCl), which along with proper fatty acid metabolism pushes the calcium into the soft tissues. Lack of stomach acid, which commonly manifests itself as heartburn and indigestion from a poor diet, stress, hydrogenated fats and not enough healthy omega 3 and 6 fats will leave the calcium with no place to go.
