Unfortunately, not all people get enough calcium from food, and this is because of many reasons, like an allergy to dairy products or vegans and people who are lactose intolerant.

So, if you don’t drink milk or eat dairy products you could be at risk of calcium deficiency.

The recommended daily allowance (RDA) for women and men is 1,000 mg to 1,300 mg, depending on your age.

How To Prevent Calcium Deficiency


Eating a diet that has adequate calcium and vitamin D can be beneficial in preventing calcium deficiency.

Calcium is found in many foods, you can get the recommended amount of this mineral by including these foods in your diet:

  • Include dairy products in your diet every day ( milk, yogurt, and cheese).
  • Leafy green vegetables (kale, cabbage, broccoli).
  • Fortified foods with calcium, like breakfast cereals, fruit juices, soy, and tofu.
  • Include brazil nuts or almonds in your diet.

Vitamin D

Vitamin D helps the absorption of dietary calcium into your blood. The lack of this vitamin can cause calcium deficiency.

It has been shown in some studies that vitamin D along with adequate calcium increase bone density and decrease fractures in postmenopausal women.

Vitamin D production by the skin is dependent on exposure to sunlight. So, getting regular exposure to the sun can help boost your vitamin D levels.

To increase the absorption of calcium, you can also add food rich in vitamin D to your diet, such as fatty fish (salmon, tuna), eggs, fortified orange juice, Portobello mushrooms.

According to the national institutes of health, the daily recommended dietary allowance (RDA) For Vitamin D are:

  • 800 IU/day for men and women over the age of 71
  • 600 IU/day for women in other age groups, men, and children
  • 400 IU/day for infants under 12 months

Calcium deficiency can occur for many reasons and it can easily be prevented through a healthy lifestyle, dietary changes, exercising regularly, and restricting tobacco use and alcohol intake.
