Hi there 😊. Fair points. Calcium is indeed important, and suplements won't ever replace the real source. But sorry I don't agree with everything you wrote. For example, low-fat dairy isn't actually good for health. Especially most of the products we get are processed anyway. So cheese and yogurt - yes. But no low fat. Milk not necessary. And as always it would be good to simply have well balanced diet, rich in various products. For example some seafood, many seeds like sesame and chia, or white beans include a lot of calcium too. All of all it can save you. Not necessary only dairy products themselves. Cheers!
