how many cups of calcium should a young adult drink a day
The recommended daily allowance for calcium is 1,000 milligrams for young adults and 1,200 for adults 50 and over. A cup of milk has about 300 milligrams, making it an obvious shortcut. The RDA for potassium is a whopping 4,700 milligrams (4.7 grams), a level that fewer than 5% of Americans actually meet.
