Which brand is better, Randy calcium tablets or calcium tablets? Can you give an example to explain it in detail?

The ingredients of these two brands of calcium tablets are calcium carbonate and D3, which is 30%-40% in terms of human absorption and utilization. Calcium carbonate is characterized by higher calcium content than other types of calcium, but it is easy to constipation.

Be sure to say which brand is good. It has been verified by the market for a long time. Previously, the taste and solubility of Wen Lan granules were not very good. I tried it again this year and felt that the taste and solubility were much better. How to choose? Calcium tablets are only tablets and chewable tablets, and Randy has granules, which can be chosen according to habits and convenience.
