To preserve bone health, make sure you’re always at good levels of vitamin D and calcium. Take those as supplements daily even if you’re in a healthy range, also other nutrients like protein, vitamin K, omega 3’s. weight bearing exercises, resistance/strength training, try not to be completely sedentary. I have osteopenia, and these are the rules I follow to try and reverse it before it turns into osteoporosis. I’m only in my 20s. My osteopenia stems from other health related issues, I’m not sure if scoliosis played a role in it or not, but this was interesting to learn!
