With suppliments yes. The best source of calcium is from the dark green leafy veggies and does not have that issue because it has the balancing magnesium with it. Osteoporosis is not natural. The cause for it is usually medications.

Unfortunately, magnesium was very deliberately removed from Everything... to make sure there would be Zero Mg in any food or seed... even if you grow the food yourself (in most zones)... because the soil itself is tainted... and the seeds are all GMO. It is why depression and inflammation is so high. Magnesium is the natural Tranquilzer of the human body... and the only way to get it is to take it in supplement form. They are interfering with the supplemental form as well... because they know the population is seeking them now.

We Do get a lot of Calcium in dairy etc... which is Bad for us... not good..... because our intake of Vitamin D3 and Magnesium is way too low. Without those 2 minerals Calcium hurts us. They don't tell you that for good reason.
