You need to take Vitamin D3 and Vitamin K2, I also take co-enzyme q10 and also I use a good sea salt (Celtic or Himalayan pink salt are the best). Weight bearing exercises and walking are essential or your bones won't grow back strong. I chose not to take osteoporosis medication. This is a youtube video I found interesting and helpful.
