Needless to say, the popularity of Calci in the Chinese market is to talk about Calci, and its parent company Pfizer has to be mentioned. Pfizer is one of the largest pharmaceutical companies in the world, and OTC drugs have always been at the forefront of the Chinese market, with a market share of 13.2%. Among them, the most well-known OTC products are the calcium supplement "Calqi" and the multivitamin "Shancun" of the Health Drug Department, which have a cumulative market share of 12.6%, ranking among the top three in China's OTC mineral supplements and vitamins respectively.
 
Calcci is also the first internationally renowned calcium supplement brand to enter China, and calcium itself is recommended by many pharmacists, and in the 2018 U.S. Pharmaceutical Times survey, Calci received the second highest number of pharmacist votes after Citracal, the first place.
 
Calcium's calcium supplements are all based on calcium carbonate as the source of calcium, which is suitable for most people with healthy stomachs. In general, the dosage of domestic calcium tablets is smaller than that of American products, which is convenient for flexible dosage adjustment, and its recommended dosage is also more suitable for Chinese. If you have doubts about the origin when choosing calcium, it is recommended to use domestic products as the first choice. The vitamin D content of domestic calcil calcium tablets is generally not high, if you take vitamin D or do not have enough sun exposure, you can take other supplements containing vitamin D at the same time (depending on the specific dosage of other supplements).
 
Calcium calcium carbonate D3 tablets are almost the most well-known and sales calcium supplement in the Chinese market, and each tablet has a high calcium content and recommended dosage, which is suitable for menopausal women, the elderly and other groups with high calcium needs. This calcium supplement 100 tablets is about 100 yuan, each tablet contains 600mg of calcium, the product is recommended to take 1-2 tablets per day, but the dose of two tablets exceeds the recommended intake of calcium, if it is not a serious calcium deficiency, it is recommended not to take more than 1.5 tablets, patients should consult a doctor according to their own conditions.
 
Caltrate 600 D3 is the American version of Caltrate Calcium Carbonate D3 Tablets, the composition and amount of calcium are very similar, the difference is that the vitamin D content in Caltrate 600 D3 is much higher than that of Caltrate Calcium Carbonate D3 Tablets, which can meet people's daily vitamin D needs without additional supplementation. This 320 American calcium tablets are about 140 yuan, and the price is much cheaper than Calci calcium carbonate D3 tablets.
 
Significantly different from the above two calcium supplements, Calcium Vitamin D Vitamin K Softgels and Golden Calcium Vitamin K Softgels only contain 300mg and 273.5mg of calcium respectively, and the recommended dosage of two tablets per day is very appropriate. The selling point of the former is vitamin K, while the latter emphasizes the addition of minerals such as magnesium, zinc, and copper, all of which are beneficial for bone health.
 
The main difference between them is that calcium vitamin D and vitamin K softgels are easier to digest and disintegrate, and the capsule is small in size and easy to swallow. As a liquid softgel, the price of calcium vitamin D and vitamin K softgels is correspondingly higher, about 168 yuan for 166 tablets. 100 tablets of Jin Calcium Erqi Tianjia are about 80 yuan, and the price is not low according to the amount of calcium. If cost performance is the first choice, these two products are far less affordable than the Chinese and American versions of Calci calcium carbonate D3 tablets.
