As the name suggests, milk calcium comes from milk, and the calcium in breast milk is definitely the best, but only babies can get it. Adults get their calcium from a variety of calcium products, the most common being milk. Whole fresh milk is the best, which is rich in fat-soluble vitamins A, D, E, K, etc., and can also promote the absorption of calcium, while skim milk has lost a lot of nutritional value because of the loss of vitamins A and D due to the removal of lipids, but many elderly people have hyperlipidemia, it is better to choose skim milk, and vitamin D can be supplemented separately. Milk derivatives, such as yogurt, cheese, chocolate, etc., are good foods for calcium, but because of high calories, added sugars and other factors, it is not good for older people. There are still very few manufacturers out there who have come up with milk calcium extract, which is a more frugal capsule that is usually given to infants and can be squeezed into their mouths. Careful readers can go online and look for it. But also have to pay attention to the cottage false lactic calcium, is the milk concentrate and calcium carbonate mixed up, also called “lactic calcium”, in fact, is the cow’s milk + calcium carbonate, there are really a lot of such confusing concepts manufacturers. In addition, it should be noted that there is a class of “high-calcium milk” on the market, this milk added extra calcium is not mostly lactic calcium, but other salts of calcium, such as calcium carbonate, the absorption rate is low. So, with this free money, it is better to buy more pure milk to drink. In fact, calcium carbonate is also a common calcium preparation in everyday health products and drugs, the famous “Calcium D” is calcium carbonate plus vitamin D, because calcium carbonate has a certain stimulus to the stomach, eaten after the old feel a little indigestion. But the absorption rate of calcium carbonate is still quite high, so most of the pharmaceutical preparations are based on it as a raw material. As mentioned earlier, many high-calcium milk added is this calcium carbonate, the raw material source is relatively simple (stone is calcium carbonate, everywhere), the cost is relatively low, so these health care products and food factories like to use it as an additive (lactic calcium more expensive ah, fools will use it to do high calcium additives). Three, amino acid chelated calcium amino acid chelated calcium is also a very good calcium, more well-known drug is the United States of America, “Le Li”, it is more calcium carbonate advantage may be a little less gastrointestinal discomfort. Now many domestic manufacturers are developing and marketing amino acid calcium (you Baidu found false exaggerated promotion especially more than 95% absorption rate, we have seen in the literature its absorption rate is not very high), the variety is also very much, as for the quality of how, no one knows. Fourth, calcium lactate Calcium lactate in children’s calcium products more, the most famous is a brand called “Golden Band”, advertising is also particularly fierce, the advantage is easier to dissolve into the water, so infants and children are more acceptable. The absorption rate is low, but the fish and the bear’s paw can not be both. Five, calcium gluconate advantage is good taste, easy to dissolve into the water, oral liquid mostly. Other than that, not much to say.
