Teenagers who suffer from "growing pains" will usually find that they disappear with an increase in calcium consumption. Long-term high dairy calcium intakes may increase the rate at which dietary fat is burned. Hypoglycemics could use more calcium in a dosage of 1,000 -1500 mg daily. If you consume lots of cola drinks, be aware that, because they are high in phosphoric acid, you may be depleting your body of calcium and increasing your chances of osteoporosis. You need extra calcium if you have been bedridden for a week or more. The body does not absorb calcium well if more than 500mg are taken at one time, so divide your daily dosages into 500mg to prevent stiffening of joints and hardening of arteries.
