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.
I think Calcium supplementation is unneeded for most fit people. It is needed for those who are obese and for older americans with osteopenia or porosis but even there I dont use a whopping dose. I push Magnesium way more. 1000mgs a day is enough and 2 eggshells is fine. A guy like you Person has good Ca regulation most likely so you will easily have the hormonal machinery to handle any excess
I don't know. I can only tell you that since I've added milk and a pint or two of H-D ice cream back to my diet, a long-standing tendon problem has virtually disappeared. I cannot account for others, but I was eating too little of it, it would seem.
Calcium seems to be the boogeyman lately. I too eat eggshells, but I take 1/2 tsp ground.
Too much calcium can be constipating. So that's a pretty straightforward sign.
Too little calcium can be a little harder to "symptomatize" but here's something interesting I learned recently about calcium. If you have cravings, particularly for sweets and carbs, that can be a sign of needing more calcium in the gut. Here's what a smarter person had to say on the subject:
Calcium has been found to regulate the Agouti gene. If calcium is too low then the Agouti gene signal is too high, in turn ramping up NPY, and consequent food cravings (and consequent hot flashes in menopausal women). By increasing calcium intake the Agouti signal is turned down, NPY levels are lowered, and cravings go away – and your head wakes up!away – and your head wakes up!
