Why is Vitamin D Important For Babies?

For growing babies, there must be a perfect balance of various nutrients to ensure ideal health conditions. The body can manage a mild deficiency or excessiveness of any nutrient. Beyond a limit, the body starts suffering.

Here is why vitamin D is important for babies.

  1. The main bases of human bone are calcium and phosphorus. These elements make the bone structure and provide the required strength.
  2. Vitamin D is the element that helps the intestinal lining of the body to extract the necessary amount of calcium from foods and diffuse it in the blood.
  3. According to a report by NHS, calciferol also regulates the amount of phosphates in the baby’s body, which is also vital for their skeletal development.
  4. Vitamin D is great for improving heart health and functioning.
  5. This vitamin also reduces the risks of several infections by improving immunity.
  6. Vitamin D also helps in the generation of calcium, which is vital for the balanced functioning of the baby’s body cells.
  7. According to the National Center for Biotechnology Information, the cause of Rickets or osteomalacia is caused by the deficiency of vitamin D.
  8. Rickets is a disease where children develop weak and soft bones. Prolonged deficiency of calciferol can cause this severe issue in babies.

Types of Vitamin D You Should Give Your Baby

Types of Vitamin D

As it is hard to get enough vitamin D from food intake, experts always suggest taking vitamin D supplements to mitigate the daily requirement of this essential element. Usually, there are two different types of vitamin D supplements available.

  • Vitamin D2 or ergocalciferol
  • Vitamin D3, which is also known as cholecalciferol

D2 is found in plants and fungi, but vitamin animals are an excellent source of vitamin D3. According to studies, vitamin D3 is more efficient and powerful than vitamin D2. Therefore, as a supplement, cholecalciferol or D3 vitamin is recommended by health practitioners.

Ideal Dosage of Vitamin D For Babies

Mostly, vitamin D is synthesized by the human skin in the presence of sunlight. It helps to extract calcium from the foods we consume. But as most foods are not enough to fulfill the daily requirement, doctors often recommend vitamin D supplements for children. The frequency of this dosage may vary from daily (with a little amount) to weekly high dosage to once a month.

Babies under the age of 1 year need 8.5 to 10 micrograms of vitamin D daily. A microgram is 0.001 times a milligram and is often denoted by μg. The standard notion of vitamin D is mentioned in International Units or IU. Therefore, you can define one microgram of vitamin D as 40 IU.

Children above one year and adults need ten micrograms of vitamin intake daily. People with vitamin D deficiency, pregnant women, and breastfeeding mothers also need the same amount for good health. The sufficient weekly dosage is 50 micrograms for healthy functioning of the body.
