Calcium And Vitamin D Needs In Children And Their Sources


T​he foods we eat have important minerals and vitamins that help build strong and healthy bones. Calcium and vitamin D are two important nutrients for bone health.


Almost all the calcium in the body is found in the bones and teeth. Calcium is also found in the blood, where it helps the heart, muscles and nerves to work properly.
The bones are like a bank – they build up deposits of calcium from the foods that we eat and drink or from calcium supplements. They also ‘give’ calcium to the rest of the body by allowing it to enter the bloodstream.
If you do not eat enough calcium, your body cannot replace the calcium that the bones lose quickly enough. Soon, the bone bank becomes empty and bones get weaker.

* How much calcium does a person need?

The amount of calcium that a person needs is based on their age, as you can see in the table below :
Age                 Amount of calcium everyday
0-6 months –           210 mg
​7-12 months – ​        270 mg
1-3 years –              700 mg
4-8 years –             1000 mg
​9-18 years –           1300 mg
​19+ years ​ –           1000 – 1200 mg

Food sources of calcium

You can use the calcium-rich foods listed in the tables below to reach the recommended daily intake of calcium for you and your family.

#Excellent choices :

  4. Soybeans, cooked
  5. Tofu, firm, made with calcium
  6. Sardines
  7. ​Soybeans, roasted ​

  1. Yogurt
  2. Yogurt drink
  3. Salmon, canned with bones
  4. Blackstrap molasses ​

Helpful hint:

  1. Look at the serving sizes on food labels to find out how much calcium you are eating.
  2. Other ways to add calcium to your family’s diet
    Use milk instead of water when making soup or oatmeal.
  3. Make “smoothies” using yogurt, fruit and milk.
    Offer yogurt for a dessert or snack.
  4. Serve your child calcium-rich snacks, such as cheese cubes, yogurt, tortillas, almonds or cereal with milk.
  5. Add shredded cheese to tortillas, soup and stews.

Calcium supplements :

If your child cannot eat or drink all of the calcium they need in a day, they may need to take calcium supplements. These can be in a liquid, a pill or capsule, a chewable tablet, a gummy or a dissolving tablet. Talk to your child’s doctor, dietitian or pharmacist before starting your child on any supplements and tell them if your child is taking any other medication.

Tips for taking supplements

  1. Read the label of the supplement to find out how much elemental calcium each serving contains. Watch for the weight in mg of elemental calcium, not the weight of the tablet itself.
  2. Do not give your child any more than 500 mg of elemental calcium at one time.
  3. Give calcium supplements with food. They are best absorbed on a full stomach.
  4. Do not give calcium supplements at the same time as other medicine. The calcium may make other medications less effective. For example, calcium can make it harder for the body to absorb iron and antibiotics.

Vitamin D

Like calcium, vitamin D is very important for growing bones. Calcium needs vitamin D to help it move from the stomach to the bloodstream and from the bloodstream into the bones.
The amount of vitamin D that a person needs is based on their age and bone health, as you can see in this table.

0-1 year – 400 IU
​1-3 years ​-600 IU ​
4-8 years- 600 IU
9-18 years-600-1000 IU
19+ years – ​600-1000 IU ​

Sources of vitamin D :

You can get vitamin D in three ways:

  1. Exposing the skin to direct sunlight
  2. Eating foods that are rich in vitamin D
  3. Taking a vitamin D supplement.

1.Sunlight – Your body can make vitamin D naturally from being exposed to 10 to 15 minutes of sunshine two or three times a week without sunscreen. However, most of us cannot make enough vitamin D naturally year round. It is harder to make enough vitamin D if:
1.A person’s skin is not exposed to the sun for long enough, for example if they work indoors or wear long robes or head coverings.

2.A person lives in a northern community- where periods with little sunshine in the winter months
a person has dark skin – the higher level of melanin in the skin interferes with the body’s ability to make vitamin D.

3.Many people need to take vitamin D through their diet or from supplements to prevent a vitamin D deficiency.​

Foods sources of vitamin D

The foods listed in this table are excellent sources of vitamin D.

  1. Salmon, canned, pink, with bones
  2. Sardines
  3. Tuna, canned, light ​
  4. Milk
  5. Orange juice fortified with vitamin D (such as Minute Maid)
  6. Fortified soy or rice beverage
  7. Fortified margarine
  8. Egg (yolk)

Vitamin D supplements

Unfortunately, not many foods are rich in vitamin D. As a result, many people may need a vitamin D supplement to get enough vitamin D every day. Supplements come in tablets or drops. Ask your pharmacist for help when you buy them.
If your child finds it hard to remember to take their vitamin D every day, they can take a whole week’s worth of vitamin D on just one day and repeat that every week. For example, if your child usually takes 1000 IU of vitamin D a day, you may give them 7000 IU of vitamin D on one day of the week and repeat it on the same day the next week.

This approach does not work for all vitamins and minerals. Most of them need to be taken in much smaller doses. In fact, some vitamins and minerals can be very harmful if someone takes too much at one time. Always ask your doctor or pharmacist before you group daily doses of any vitamins or minerals together.

Key points:

  1. ​Calcium and vitamin D are two important nutrients for bone health.
    Good sources of calcium include milk, cheese, soybeans, tofu, sardines, salmon, blackstrap molasses, almonds, sesame seeds, broccoli and kale.
  2. Sources of vitamin D include sunlight and foods such as sardines, salmon, tuna, milk and fortified orange juice.
  3. Many people need to take a supplement to make sure they get enough vitamin D every day.
