Hi
@Cheesus I don't have any advice for you, but I do recall reading about jessica (fb: worldofoneroom) having severe osteoporosis, and in a semi recent video she mentioned that her bone density had improved considerably. I don't know what she did, I don't remember which video it was but I definitely remember her mentioning it.
Might be worth contacting her, i'm sure she wouldn't mind giving you some info.
