Hello 4 yr old son having issues with dairy. we need to get calcium supplement. what type would you recommend and why? tricalcium phosphate?

Calcium is calcium: Although many doctors have their favorite type of calcium for supplementation, no studies have clearly shown one type of oral calcium supplement to be superior to others, assuming equal purity and quality control. My favorite is coral calcium; it seem more nature and some people claim more absorb-able.

Easy substitutes: You will find that Almond or soy or goat milk have calcium in amounts that are similar to cow milk, making 1:1 substitution easy. Tums makes a flavored chewable wafer that can also easily meet their needs.
