I couldn't agree more with stellar2023. I was doing the same thing, but recently found out I have an immune response to casein, the protein in dairy. So, I had to start supplementing to get adequate calcium. I take 500mg hydroxyapatite in divided doses, and citrate 500mg in divided doses. I have found that elemental citrate in powder form is much better absorbed than tablets and you can really control how much you take...and, it's cheap. I also take vitamin d, K2, and magnesium. I eat lots of protein, get as much exercise as possible and hope for the best!
