While eating calcium is better for your bones, it can be quite a challenge to eat the recommended 1,000 mg daily. That's where calcium supplements can lend a healthy hand. Both calcium carbonate, found in Tums, and calcium citrate in Citracal work well as supplements. However, calcium carbonate is best absorbed with food and generally has more calcium per tablet, which means it is more cost effective since you can take fewer pills. If you're the forgetful type though, calcium citrate might work better for you. Your body absorbs it well with or without food, so you can take it anytime during your day and reap all the benefits of the supplement.
Do you take a calcium supplement? If so, do you know which version of the mineral you take?
