@janetilley Please realize that milk is considered to be an adequate source of calcium but you must get a lot of calcium daily to maintain your blood calcium levels. Your body will rob your bones of calcium in order to maintain the blood calcium if your dietary intake is not sufficient. This is how most bone problems develop as we age and our diet changes.

One 8oz glass of milk has about 20-25% of your daily needs for calcium. At that rate you would need to drink 32-40oz of milk to get 100% of your requirement. You need to ensure your calcium intake is sufficient from other dietary sources if you are not taking a calcium supplement. You poop and pee excess calcium out so it is not a toxic problem when ingested within reasonable amounts.
