Men 51-70 yrs old = 1000 mg/day. Men 71 yrs old = 1200 mg/day. Women 51 yrs old = 1200 mg day. (+) risk of kidney stones and urinary dysfunction. Interference with the absorption of other minerals. Second most abundant mineral in the body. Used in energy transfer and buffer system that maintain acid/base balance. Adequate intake met if protein intake sufficient. Stabilizes protein shape by creating disulfide bridges. Part of the vitamins thiamine and biotin and the hormone insulin. Would only occur if sulfur containing amino acids were eaten in excess. Part of the proteins hemoglobin and myoglobin. Carries oxygen in the blood and to the muscles for contraction. Necessary for the utilization of energy as part of the metabolic machinery.

What must happen to intracellular calcium levels for this to occur? 2- What changes in other electrolytes would be expected in hypoparathyroidism-associated hypocalcemia, and what are the expected manifestations?
