I have been taking the AlgaeCal collagen in conjunction with Tymlos and at 1 yr saw incredible results on my DEXA. Out of osteo and back into osteopenia. My endo doc believes my results are not all due to Tymlos and asked me what else was I doing. I have not even been exercising! The only thing I have been doing religiously is taking my HRT and the AlgaeCal collagen. My hair, skin and nails have been going crazy so I assume it has had an effect on my bones too.
