 With calcium being something to deal with stress, isn't calcium for building bones? Well, yes. Okay. And it does build your teeth. But you see, 1% of the calcium actually circulates in your blood. So when that 1% starts to drop, it could affect your heart, your brain, your kidneys, your organs, and your body shuts down and actually dies. Wow. So 1% of the calcium always has to be in your system.
