Worksheet to Estimate Your total Daily Calcium Intake

Step 1. Estimate the Calcium in the Foods You Eat in a Usual Day

The amount of calcium in foods varies depending on the brands you buy. It is important to read labels. The food label does not list calcium in milligrams (mg). Instead, the label lists calcium in each serving as Calcium % (Calcium as a Percent Daily Value or %DV).

Finding the Calcium (mg per serving) from Calcium% is as Easy as 1, 2, 3:

1. Find the serving size: For example: One serving of low fat cheese is 1 ounce.

2. Read the %Calcium per serving. For example: 1 serving contain 20% Calcium.

3. Simply drop the % and replace with a "0" to find the mg calcium per serving.

For example: 20% Calcium = 200 mg calcium,

Other examples: 30% Calcium = 300 mg calcium, 100% Calcium = 1000 mg calcium.

For the foods listed below, fill in the number of servings you eat on a usual day.
Servings per Day
Calcium (mg per serving)
Calcium (mg per day)
Milk _____________ X 300 _________________
Most milk contains Calcium 30% DV per serving,
One serving = 8 ounces fat-free (skim), low fat (1%), reduced fat (2%), whole, lactose-reduced, chocolate milk, buttermilk or goat milk. Include the amount of milk used in cooking and added to soups, puddings, cereals, and other foods.
Yogurt _____________ X 200 to 350 +________________
Most yogurts contain Calcium 20% to 35% DV per serving. One serving is usually 6 ounces.
Cheese and Mixed Cheese Dishes _____________ X 200 +________________
Most cheeses contain Calcium 20% DV.
One serving = 1 ounce, 1slice or 1 ½ inch cube cheese, ¼ cup ricotta cheese, ½ cup fortified cottage cheese, 1 cup mixed cheese dishes (macaroni and cheese, cheese soufflé, lasagna, manicotti, ziti, or quiche),or 1 slice pizza.
Calcium Fortified Beverages _____________ X 100 to 350 +________________
Most calcium fortified beverages contain Calcium 10% to 35% DV per serving.
One serving = 8 ounces of beverages with added calcium. Include fortified almond, coconut, rice, and soy beverages, and some juices.
Calcium Fortified Foods _____________ 100 to 1000* +________________
Most calcium fortified foods contain 10% to 100% DV calcium. Serving sizes vary. Foods include some cereals, granola bars, pastas, rice, breads, and other foods.
Calcium from Other Foods     + 250
250 mg is the typical calcium intake from other foods with smaller amounts of calcium per serving.
Estimated Daily Calcium in the Foods You Eat = (Add all the above) =________________
*If foods are high fortified, it is wise to choose smaller portions. For example, if a food contains 100% Calcium per servingor1000 mg per serving, it would be best to eat a half-serving at one time.

Step 2. Know How Much Calcium You Need Each Day

For strong bones for life, you need the recommended daily calcium intake. You will find your recommended daily calcium intake on the chart below, listed according to your age and gender.

If this is your age Then you need this much calcium each day
(mg = milligrams)
Birth to 12 months Supplied by formula or breast milk
1-3 700 mg
4-8 1000 mg
9-18 1300 mg
Men 19 – 70
Women 19 – 50
1000 mg
Women 51-70 1200mg
Men and Women 71+ 1200 mg
Recommended Dietary Allowances, Institute of Medicine, 201

Rarely, people with medical conditions or who take certain medications need slightly more calcium than listed above. Be sure to speak to your healthcare provider to find out if your medical conditions or medications increase your calcium needs.

Step 3. Calculate Calcium Needed to Meet Your Recommendations

Take Your Recommended Daily Calcium Intake (from Step 2)  ____________ mg
Minus Your Estimated Daily Calcium in the Foods You Eat (from Step 1) -____________ mg
Equals Calcium Needed =____________ mg

  • Food is the best source of calcium. If you consume less calcium than recommended, first try to eat more calcium rich foods to get the calcium you need each day.
  • Your body uses calcium best in amounts of 600 mg or less at one time of the day. It is best to spread out the calcium you eat by choosing a calcium rich food at each meal. .
  • More calcium is not better. If you get the recommended amount of calcium from the foods you eat each day, you do not need a calcium supplement. Supplements should only be taken when you have difficulty getting enough calcium from food alone.
  • If you are considering a calcium supplement, speak to your healthcare provider to help you select the amount and type of calcium that is right for you.

Step 4. Estimating Your Total Daily Calcium Intake (If You Take Supplements)

1. Estimated Daily Calcium in the Foods You Eat (from Step 1) _____________ mg
2. Calcium from Calcium Supplements _____________ mg
3. Calcium from Vitamins _____________ mg
4. Estimated Total Daily Calcium Intake ( Add 1+2+3) _____________ mg
