According to a recommendation made by the Department of Agriculture, it’s best to consume 2 to 3 cups of milk. Milk serves as an excellent source of calcium providing more than 300 milligrams per 8-ounce glass. To meet the daily calcium requirements, women need 1,000 milligrams of calcium per day while men need 1,000 milligrams, so drinking 2 to 3 glasses will help you meet your dietary needs.
