Hi I have Osteoporosis and have tried Alentronic Acid and Strontium Ranelate and have had side effect with both. What to do now! I notice also that there is a sweetner in the Calcium tablets I take so I have ordered Algaecal Plus which is said to come from a natural source. Has anyone any info on this as I take Calcichew D3 Forte at the moment but would like to change to the above. I would like to try a natural way of trying to improve my bone quality as I am concerned about trying another medication and getting more side effects. Anyone know any ways that have improved bone quality?
