Taking Calcium and Vitamin D Supplements After Your Parathyroid Operation This handout explains how to meet your daily calcium and vitamin D needs after your parathyroid operation, once your calcium level (blood test) has returned to the normal range. Calcium is important for people of all ages for good health. Calcium is a mineral that helps form and maintain healthy bones and teeth. It is needed throughout your life. Most of your bone mass is built when you are a child or young adult. After the bone building period ends, bone mass must be maintained. The main way to build and maintain bone mass is to have a diet rich in calcium and to take vitamin D. The body does not use calcium well if you do not get enough vitamin D. Vitamin D also decreases bone loss and lowers your fracture risk. A natural source of vitamin D is the sun. Given the risks to sun exposure we recommend taking a vitamin D supplement. Calcium needs are based on the amount of bone and tissue growth during phases of the life cycle. The calcium and vitamin D needs advised by the Food and Nutrition Board, Institute of Medicine, and the National Institute of Health are shown below. Life Stage Age Recommended Dietary Allowance Calcium(mg) Vitamin D(IU) Adolescents 9 18 years 1300 800 Adults: Men and Women 19-50 years 51-70 years 71 years and older 1000 800 1200 (women) 800 1000 (men) 1000 1200 (women)
Foods That Are Good Sources of Calcium 250-300 mg of Calcium 2 pieces cheese pizza (1/4 of 14 pie) 8 oz. milk (cow, almond, rice, soy, or fortified) 6 oz. low fat yogurt 8 oz. calcium-fortified orange juice or other fruit juices 1 oz. cheese. Hard cheese has more calcium 3 oz. sardines, canned, drained, including bones 1 cup macaroni and cheese, homemade ½ cup tofu with calcium 8 oz. frozen collard greens 200-250 mg of Calcium 1 cup macaroni and cheese, packaged 6 oz greek yogurt 8 oz broccoli rabe 150-200 mg of Calcium ½ cup cottage cheese ½ cup ice cream or frozen yogurt ½ cup au gratin potatoes 1 cup cream soup made with milk 3 oz. salmon, canned with bones 1 taco with beef and cheese 2 frozen calcium fortified waffles 4 oz baked beans

Calcium Supplements If you re not meeting your daily calcium needs through your diet, you should think about adding calcium tablets. Calcium tablets take the form of calcium carbonate, calcium citrate, calcium gluconate, or calcium lactate. The table below compares calcium carbonate and calcium citrate supplements and the best time to take them. Calcium gluconate and calcium lactate cost more and contain less calcium per pill so you d have to take more pills to get the same amount of calcium. Note: if you are taking medicine to decrease stomach acid (acid blockers) or use antacids on a daily basis, calcium citrate is advised instead of calcium carbonate. Calcium Citrate (Citracal) Can be taken any time during the day. Does not require stomach acid to be absorbed. Gentle on the stomach. Calcium Carbonate (Tums, Oscal, Caltrate, Viactiv, CalBurst) Must be taken with meals or snacks to be absorbed best Stomach acid is needed for it to absorb. Do not take with antacids. May cause gas, constipation, and bloating Look for "USP" on label or box (confirms pill will dissolve in normal amount of stomach acid.)

What about other medicines? Calcium (supplements) may not mix well with other medicines. Make sure to tell your health care practitioner that you are taking calcium so they can help you determine the best time of the day to take your calcium. How do I take my calcium? Calcium is best absorbed if taken with meals and in smaller doses. Avoid taking more than 600 mg of calcium at one time so your dose should be split and taken throughout the day with 8 oz. of water. Chewable forms of calcium should be chewed well. Are there any side effects? Side effects with the proper use of calcium are rare. Constipation and gas can also be problems with calcium use. Make sure you drink plenty of fluids and eat fiber to avoid these problems. If these measures are not helpful, try switching to a different form of calcium.
