The plasma total calcium concentration is in the range of 2.2–2.6 mmol/L (9–10.5 mg/dL), and the normal ionized calcium is 1.3–1.5 mmol/L (4.5–5.6 mg/dL). [4] The amount of total calcium in the blood varies with the level of plasma albumin, the most abundant protein in plasma, and therefore the main carrier of protein-bound calcium in the blood.
While catabolysis can be deadly over time, if the person is given medical treatment early enough, the effects of catabolysis can be reversed. However, the person may require intravenous nutrition, a blood transfusion, and/or oxygen replenishment. After that, it may be a few weeks to a few months before the person's muscle mass and fat deposits ...
The diet must ensure optimal calcium intake (of at least one gram daily) and measuring vitamin D levels is recommended, and to take specific supplements if necessary. [123] Osteoporosis can affect nearly 1 in 3 women and the bone loss is the most rapid within the first 2–3 years after menopause.
Disorders of calcium metabolism occur when the body has too little or too much calcium. The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium ...

Supplementation is generally only required when there is not enough calcium in the diet. [2] [3] By mouth they are used to treat and prevent low blood calcium, osteoporosis, and rickets. [1] By injection into a vein they are used for low blood calcium that is resulting in muscle spasms and for high blood potassium or magnesium toxicity. [2] [4]
The pump is powered by the hydrolysis of adenosine triphosphate (ATP), with a stoichiometry of one Ca 2+ ion removed for each molecule of ATP hydrolysed. It binds tightly to Ca 2+ ions (has a high affinity, with a K m of 100 to 200 n M ) but does not remove Ca 2+ at a very fast rate. [ 6 ]
