@bearbayou Perhaps I should have said I'm very doubtful that AlgaeCal can increase bone density rather than that I'm fairly certain. I haven't had a follow-up DEXA scan for 10 years. Due to having had two hip replacements and arthritis in the spine I've been told the numbers wouldn't be accurate. I'm also rather skeptical about DEXA to begin with; its diagnostic categories are arbitrary and I believe the scores are geared to overtreatment.
