Help please! When should I take my calcium supplements?

Spread out. Hi. Calcium supplements are fractionally a little better absorbed if they're broken up into several times per day than all at once. The trade off is that people often don't remember to take things multiple times/day, and if you forget, you're better taking a bunch all at once than not taking it at all. And don't forget to get enough vitamin D (preferably D3, a few thousand units/day).
