Hello there, Has some doctor or Nutritionist suggested her the suppliment? There is no link whatsoever in Literature between the efficacsy of carnite suppliment to that of osteopenia? What are the dietary habits of your mother? Like veg/nonveg Any dairy products etc. Proper history of past and present illness should be evaluated before any suppliment is started...some times side effects can occour. Also if through natural food nutrients can be obtained then therz no need for suppliment. Get back with answer to my questions for proper advice and guidance. Regards.
