This article is from "Nankai Sun Pharmacist", which is used for medical science popularization for reference. Calci is calcium carbonate D3 tablets, which is a compound calcium supplement, each tablet contains calcium carbonate 15g (equivalent to 600mg of elemental calcium) and vitamin D3 125IU, calcium is an essential mineral for the human body, which can maintain human bone health, promote bone formation, slow down bone loss, and can also participate in maintaining the body's normal heart rhythm, muscle contraction, Coagulation function and the function of various enzymes, vitamin D is an essential fat-soluble vitamin for the human body, which can promote intestinal calcium absorption, enhance muscle strength and balance, increase bone density, prevent falls and fractures, calcium carbonate and vitamin D3 are good partners for calcium supplementation, and are mainly used in clinical practice for special populations, such as children, the elderly, pregnant and lactating women and menopausal women to supplement calcium and prevent osteoporosis.
Calcium carbonate belongs to inorganic calcium, high content of elemental calcium (40%), high absorption rate (39%), its calcium supplement effect is among the best in calcium, but it also has shortcomings, low solubility in water, absorption needs to be activated by gastric acid dissolution, easy to cause secondary gastric acid secretion, strong gastrointestinal irritation, nausea, vomiting, constipation, belching, bloating, abdominal pain, diarrhea, flatulence and other gastrointestinal discomfort, if the drug can not be tolerated, calcium gluconate, calcium lactate, Calcium acetate and other organic calcium substitution, although the elemental calcium content and absorption rate of organic calcium are not as good as calcium carbonate, but the gastrointestinal tract irritation is small and well tolerated.
Chinese Nutritional Dietary Guidelines (recommended, ** daily elemental calcium intake is 800mg, people over 50 years old and menopausal women are 1000mg, calcium supplementation should be tried through the diet, foods with high calcium content mainly include dairy products, green leafy vegetables, soy products, shrimp skin and sesame paste, etc., take people over 50 years old as an example, drink 200ml of milk every day2, you can supplement about 200mg of elemental calcium, eat 500g of green leafy vegetables such as cabbage, broccoli, camellia, spinach, Oily wheat cabbage, etc., can supplement about 500mg of elemental calcium, eat 200g of soy products such as dried tofu, tofu, tofu skin, etc., can supplement about 200mg of elemental calcium, and then eat some fruits, nuts, fish and shrimp in moderation, which can basically meet the needs of middle-aged and elderly people for 1000mg of calcium per day, but nutritional surveys show that the average intake of dietary calcium for Chinese residents is only 400mg.
Long-term consumption of calci should be noted:
1.Vitamin D3 can promote calcium absorption, easy to induce hypercalcemia, if nausea, vomiting, polyuria, anorexia, headache, muscle weakness, irritability, arrhythmia and other symptoms occur during the medication, the drug should be stopped immediately, seek medical attention in time, it is recommended to test blood calcium and urine calcium every 3 months, if there is an increase in blood calcium, the drug should be stopped, if there is an increase in urine calcium, the dose should be reduced.
2.Calcium can regulate arrhythmias, and overdose can also lead to arrhythmias, therefore, patients with cardiac insufficiency should be cautious with calci, in addition, calcium is mainly excreted through the kidneys, and overdose can lead to kidney stones, therefore, people with renal insufficiency or kidney stones should be cautious with calci.
3.Calcium carbonate absorption needs to rely on gastric acid dissolution and activation, common gastrointestinal reactions, if you can't tolerate it, you can choose organic calcium such as calcium citrate, although organic calcium content is low, but water solubility is good, gastrointestinal reactions are small, and can prevent kidney stones. In addition, meals can promote gastric acid secretion and facilitate calcium carbonate absorption, so it is recommended to take calcil 1 hour after a meal for the best effect.
