On the surface, if Bian Xiao finds that its calcium supplement effect is not good after eating it, how to introduce it? It can be seen that McKinley vd's calcium supplement effect is quite good. From a specific point of view, because each grain is very rich in calcium carbonate and vitamin d3, people's absorption of calcium will become more in place. Incidentally, when eating McKinley vd calcium, it is best to avoid eating some foods containing oxalic acid, such as spinach, because oxalic acid will further react with McKinley vd calcium to generate calcium oxalate precipitate, which is wasted and there is no way to see the calcium supplement effect that McKinley vd calcium wants to achieve. The above is Bian Xiao's answer on the topic of McKinley vd calcium. Generally speaking, because McKinley vd calcium contains a certain amount of vitamin d3, it can improve the absorption rate of calcium and the calcium supplement effect will be better.
