What supplements help Osteopenia, Osteoporosis?

Hi, I am a new member here and wanted to find out if anyone has used AlgaeCal Plus & Strontium Citrate for Osteopenia? I have had this condition for 10 years now plus five years with Osteoarthritis of the hip which I am hoping will help not only my hip but the DEXA scan came up with Osteopenia scores.
