Apart from the usual stomach pain that I had after eating wheat/gluten products I suffered very painful joints. Every morning I had to move all joints before I could even walk. Doctors didn't have a clue why. It caused me to have osteopenia. I was placed on Calcichew 4 years ago, 3 months ago the Dr gave me a cheaper calcium tablet and the pain came back. I stopped taking it, after 3 weeks the pain had almost gone so I tried the medication again, more pain. Pleased to say I am back on Calcichew and pain free. Medication should have an ingredients list for non medical ingredients.
