About how much calcium is in a cup of skim milk used for cereal?

One cup, 8 fluid ounces of skim milk has 306 mg. of calcium.

If you use 2% fat milk, the calcium is 285 mg.

Wow that's not nearly as much as I thought it would be. One of the Three vitamins I take in a day has 1000mg of calcium! Just out of curiosity, do you know about how much I should get a day if I'm 5'5'' and play soccer about 4 days a week and get pretty knocked around?

smithxi,

If you are drinking a glass of milk AND taking a couple calcium supplements each day, you can be reasonably certain you are getting enough.
People who have mega-protein inputs tend to lose a lot of calcium so they would need more.

Milk is great, but only about 35% of the calcium in milk is absorbed fully. Some supplements are also hard to digest, especially the tablets. I use only liquids, powders, capsules or softgels.

Also, the type of calcium is important, most supplements are calcium carbonate (ground oyster shells) which is very hard to absorb. I like to use calcium citrate or calcium oratate, since they are more bio-avaliable.
