Among them, Absorbable Calcium 1200mg Plus Vitamin D3 1000 IU has become the brand's highest-selling calcium supplement in the Chinese market due to its high calcium content and easy digestion. This calcium supplement is also one of the most cost-effective soft capsules calcium, only about 100 yuan for 200 capsules. However, the recommended dosage of two capsules a day (1200mg calcium), together with dietary calcium, exceeds the recommended intake of calcium in China and the United States, and there may be certain health risks, so reducing to one capsule per day is a more appropriate dose.
 
In contrast, Calcium Magnesium Vitamin D3 and Chelated Calcium Magnesium Zinc are designed to contain 1000mg of calcium per three tablets, and users can flexibly choose to take 1-3 tablets per day according to their own conditions. Calcium Magnesium Vitamin D3 uses oyster shells as the source of calcium, the main component is calcium carbonate, and the moderate content of magnesium and vitamin D is added.
 
The calcium in Chelated Calcium Magnesium Zinc comes from calcium carbonate and calcium gluconate, which is more conducive to digestion and absorption by people with indigestion. In addition, this calcium tablet is also added with magnesium, zinc and other mineral elements, which are conducive to bone growth during growth and development. It should be noted that this calcium supplement does not contain vitamin D, if the intake or synthesis is insufficient, it can be taken with other vitamin D-containing supplements. Chelated Calcium Magnesium Zinc is also cost-effective, with 250 tablets cost-effective for about 100 yuan.
 
In contrast, Calcium Magnesium Vitamin D3 is more ordinary, and the price of about 70 yuan for 120 tablets is still in the moderate price range, but it no longer has the usual price advantage of the brand.
