@happy2bhere The milligrams of calcium would be individual. Most doctors prefer you get your calcium from food. I often do take a small calcium pill for supplementation but I do get most of my calcium from food.

Here's an article about fat helping to increase the absorption of D3.

This article is about calcium. As it concludes, it is better to get it through diet than through supplements.

And one more article about calcium:

Googling for this info I learned something too. Apparently they are thinking that calcium supplements are not very helpful in preventing fractures. Interesting. Something new every day.
