Calcium Rule of 300

Do you need a calcium supplement?

Before you take a daily calcium supplement, know how much calcium you are eating in your diet. Use the CALCIUM RULE OF 300.

  1. Start with the number of servings of dairy or fortified juices you get each day.
  2. Multiply that by 300.
  3. Add 300 if you eat a well-balanced diet.
  4. The total is your calcium intake from diet.
  5. Determine your RDA and add a supplement—if necessary—to reach your goal.

Note: you might be able to reach your recommended daily allowance by adding another serving of dairy or calcium-fortified juice!

 

The Bottom Line

Only take calcium supplements to make up the difference between what you get in your diet and your RDA.
