Yes, I agree, osteoporosis can be very complex and even age, hormone driven osteoporosis can also have elements especially of malabsorption and long time cortisone use, inflammation etc. woven into the cause of the disease.

I am gluten intolerant. I do not absorb my nutrients (calcium etc anything) when my system is inflamed from gluten exposure, because of this I frequently use supplements to try and help my body as it tries to absorb the nutrients which my body needs.

I do a fairly good job of limiting gluten, but then life happens.
Ex: bought something labeled dandelion coffee; had a cup it was great and reminded me of the coffee which I love but can no longer drink.
BUT....the coffee acted weird with no grounds left so ....I asked my husband to read micro font of ingredients to me....viola, the main ingredients were rye and barley flours/etc. gluten, gluten, gluten.
Sigh....I just drank a full cup of gluten. So my white cell count will plummet, bone health will suffer, and I will be in a position of an inflamed gut that won't want to absorb any of my nutrients for a period of time until my body can heal again.
GAG... all because the gluten wasn't on the buying information and the ingredient list was too small for my old eyes to read without asking someone for help.
