Depending on what you mean by mild osteoporosis, I think you can make an impact with those improvements in nutrition, as long as you are also adding strength training. I have been vegetarian-ish for many years, but have always added fish and dairy (yogurt/cheese), and I recently added collagen peptides, but am not convinced it will matter much. Your supplements sound similar to mine. None of this has made my very low density nudge much in the past two years, but I am counting on stronger muscle to protect my bones and improved overall health. And babs is correct….any reputable doctor will investigate underlying issues first!
