My question is how much calcium should an average height/build, metabolically active young man have and what are some physical signs/symptoms of excess and deficiency? I have relied on the following signs to gauge my calcium intake levels": appearance of teeth(not displaying any translucent areas which I take to be a sign of deficiency) Stiffness of joints(stiffness proportional to excess?) heart rate(tachycardia proportional to excess) dryness of skin("...") headache("...")
I have been consuming approx. 5-10,000 i.u of vit D3(supps and sun), approx. 10,000+ i.u of vit.A(eggs, butter, red cabbage, liver), a substantial amount(albeit unknown amount) of vit.k2(from parsely and butter)and my calcium source has been eggshell exclusively(2 large chicken eggshells per day).
I am thinking that given the joint stiffness I am experiencing when I consume the 2 eggshells per day that I am O.D'ing on the calcium and should reduce. However, when i do so(to 1 eggshell per day) I begin to notice translucency in my teeth(perhaps too high thyroid hormone, perhaps too low calcium. I have researched sources that say the amount of calcium in a large eggshell is 800mg. Would this not be adequate? Would double this not be excessive? How else to diagnose joint stiffness and the teeth phenomenon? Any advice would be appreciated.
