<s>[INST] Hello, thank you for answering my question. My name is ,pe. I have Osteoporosis -2.5. I tried alendronate and Ibandronate, on the very first pill of both drugs, I had pain in the leg and hip, so I stopped. The specialist doctor now recommended Prolia injection. He said the side effects would be only dizziness or fatigue, but I read on line info and the side effects are the same as the other drugs, even more severe. I am afraid to get the injection that will give me more severe side effects. I saw on line the ad of AlgaeCal + Strontium combination that Dr.Oz recommends. I would like to get your opinion on this. Should I try the Algaecal for a year and retest to see if it helps before considering the injection? [/INST] thanks for your question ,Algaecal is a calcium supplementation you can receive it safely ..while Prolia is another medication (Denosumab ) anti resorptive medication for OsteoporosisI advice you to receive both Algaecal and prolia IF  your T score in DEXA scan is less than -2.5 .Calcitonin is less side effects than prolia .You can receive it in its nasal spray form </s>
