You are very young. Focus on the natural route for now. Don’t panic , you have time to improve your bone health. This is the route I took with my osteoporosis diagnosis at 62. Did not want to take fosmax(spelling?). Now at 72 years old, I have still maintained my height and posture. Retested 2 years ago, fell within the osteopenia range. I am still focus on diet, exercise , Vitamin D and getting sunlight. My doctor says to continue with my lifestyle.
Best wishes.
