I have heard of many ladies improving quite a bit from yoga. Specific yoga exercises done carefully can help. We also need 85 to 100 grams of quality protein in order to get enough of the amino acids and nutrition to build bone. I saw an episode about osteoporosis by Dr. Mark Hyman who talked about his patient doing yoga and improving her numbers dramatically. I see a functional nutritionist via zoom who works with him. He believes food is medicine. He is a well known board certified functional med and internal med docotor.
