Calcium Citrate (Brand CITRICAL) is my choice for calcium supplementation in those who need additional calcium for their bones.
The reasons I like this brand are:
1. The various forms that are available, from once-daily to smaller pills for those with difficulty swallowing
2. Calcium Citrate is better absorbed that Calcium Carbonate and is generally easier on digestion. Calcium can cause constipation and the better absorbed products will limit this side effect
