[Prevention is better than cure] Do you know how to take calcium tablets? As our population gradually enters the aging stage, the incidence and detection rate of osteoporosis is also increasing year by year. So when it comes to taking calcium tablets, do you also have the following common questions? Question 1: What is the best time to take calcium tablets? The best time to take calcium tablets is after dinner or before going to bed every day. There are three reasons for this: 1, the body no longer eats at night, and urine will be formed as usual, part of the calcium in the blood will continue to enter the urine, resulting in the lowest blood calcium concentration in the latter part of the night and morning, in order to maintain normal blood calcium levels, the body will use the calcium in the bones at this time, after dinner or before bedtime calcium supplementation can provide calcium sources for this calcium regulation at night, to prevent the loss of calcium in the body; 2, for the three time periods of morning, midnight and night 2, for the three time periods, due to the body’s gastrointestinal motility and absorption capacity is not the same, resulting in the effect of calcium supplementation is sequentially enhanced, to the night is the strongest, so the absorption effect of calcium tablets taken after dinner is the best; 3, calcium also has a sedative effect, which helps sleep. Question 2: What are the precautions when taking calcium tablets? 1, for people with low stomach acid, should be taken with meals or immediately after meals, because at this time the increase in stomach acid secretion is conducive to the absorption of calcium; and for people with normal stomach acid secretion, calcium can be taken between meals, because calcium with meals will affect the absorption of other elements in the food; 2, bite to take, because the increase in the surface area of the drug, conducive to the absorption of calcium; 3, divided into good results. Because even if you take a lot of calcium can not be absorbed, not only the effect is not good, but also may appear constipation, flatulence and other side effects. Question 3: What are the contraindications of the diet? 1, while taking calcium tablets should try to avoid eating a lot of spinach, peppers, parsley and other foods containing more oxalic acid, as well as drinking coffee, tea, juice and carbonated or alcoholic beverages, otherwise calcium is easy to form calcium oxalate and other precipitates, not only not easy to absorb, but also may form stones; 2, high-fiber foods (such as celery, coarse grains) and too much fat food will also affect the absorption of calcium, not recommended to take at the same time; 3, the most noteworthy is that the calcium is not absorbed. 3, the most noteworthy is that calcium tablets are best not taken with soy products and dairy products. One is because calcium is easy to clump with them, affecting the digestive and absorption function of the stomach, causing belching, indigestion and other symptoms; secondly, it may cause “milk – alkaline syndrome”, manifested as high blood calcium, alkalosis and kidney function damage; 4, some minerals or trace elements and calcium with the formation of competitive absorption Therefore, it is best to take them separately from calcium tablets. Question 4: Is it enough to take only calcium tablets for calcium supplementation? It is not enough to take only calcium tablets, but you must not neglect vitamin D supplementation and sufficient outdoor sunshine to ensure effective absorption of calcium and improve its utilization.
