How Does Vitamin D Affect The Height Of Children?

We frequently receive recommendations to ensure a varied consumption of vitamins, minerals, and proteins to foster robust bone and muscle development. Within this spectrum of nutrients, vitamin D assumes a critical function in bone mineralization and is often integrated into supplements with the purpose of facilitating the vertical growth of youngsters.

However, what precise influence does vitamin D exert on the stature of children? In our most recent article, we will thoroughly explore all the pertinent information regarding this indispensable vitamin and its correlation with the enhancement of height.

The Significance of Vitamin D

Vitamin D, often known as the sunshine vitamin, encompasses a variety of forms. Our bodies possess the remarkable ability to produce vitamin D upon direct sunlight exposure. Additionally, we can obtain vitamin D from specific dietary sources and supplements.

Sufficient levels of vitamin D are imperative for the normal growth and development of bones and teeth. This crucial vitamin also assumes a pivotal role in bolstering immune health and safeguarding against certain illnesses.

Prevention of Various Diseases

In addition to its function in enhancing calcium absorption and fostering the growth of sturdy bones and teeth, research indicates that vitamin D supplementation could offer additional advantages, including:

Diminishing the risk of multiple sclerosis. Lowering the likelihood of heart conditions like heart failure, stroke, and hypertension. Reducing the chances of severe ailments, including influenza. Aiding in the prevention of infections and autoimmune disorders.

These potential health gains underscore the necessity of maintaining adequate vitamin D levels within the body by means of proper sunlight exposure, dietary sources, and supplementation when needed. However, it remains crucial to seek advice and guidance from a healthcare professional for tailored recommendations concerning vitamin D supplementation.

Control mood and lower depression

Exposure to sunlight is supposed to boost the brain’s release of the mood-increasing hormone serotonin. Some experts have discovered the correlation between depression and vitamin D deficiency [1]. Also, a study pointed out that those suffering from depression got an improvement in their symptoms after using a vitamin D supplement [2].

Support weight loss

Those with bigger waistlines and higher levels of belly fat are more likely to get lower vitamin D levels. A few theories suppose that weighty people tend to take less vitamin D-rich foods while some might expose their skin to the sun less. In fact, a study claims that individuals with obesity who get vitamin D supplements together with a weight loss diet plan lose more fat mass and weight [3].


How Does Vitamin D Contribute to Children’s Height Growth?

Until the late 1800s, the cause of rickets, a prevalent condition impeding children’s growth by affecting the proper mineralization of their bones and cartilage, remained a mystery. Eventually, scientists unveiled that a deficiency in vitamin D underpinned this ailment. They discovered that treatments like cod liver oil and exposure to sunlight effectively combated the disease. Consequently, vitamin D-rich foods and supplements have been globally administered to children and adolescents to ensure their appropriate growth and development.

Throughout childhood and adolescence, bone formation transpires at a rapid pace, particularly leading up to puberty. Subsequently, bone formation decelerates and ultimately halts when growth plates fuse completely. Adequate intake of vitamin D becomes pivotal during this phase, as it heightens the absorption of calcium, an essential mineral vital for proper bone development and strength.

Vitamin D belongs to a category of fat-soluble secosteroids available in diverse forms. Within these forms, vitamin D2 and vitamin D3 take precedence as the major ones indispensable for height growth. Functioning as prohormones, they are artificially synthesized for the production of fortified foods and supplements. The sole disparity lies in their molecular structure. Recently, vitamin D3 has gained prominence due to its natural form, as it aligns with the type synthesized by the body upon sunlight exposure.

How much vitamin D do children need?

Vitamin D is measured in international units (IU). And the recommended daily amount of this vitamin from the National Institutes of Health (NIH) is:

  • 400 IU (10 mcg) for infants from 0 to 12 months
  • 600 IU (15 mcg) for children from 1 to 18 years old
  • 600 IU (15 mcg) for adults up to 70 years old
  • 800 IU (20 mcg) for adults over 70 years old
  • 600 IU (15 mcg) for pregnant and lactating women

What if children get too much vitamin D?

While vitamin D is essential for proper growth and development in children, excessive intake can lead to potential health concerns. Vitamin D is a fat-soluble vitamin, which means that it can be stored in the body and accumulate over time. This accumulation can result in a condition known as vitamin D toxicity or hypervitaminosis D.

Excessive levels of vitamin D can lead to an over-absorption of calcium from the intestines, causing a condition called hypercalcemia. Hypercalcemia can lead to various symptoms and complications, including:

  • Digestive Issues: Excessive vitamin D can cause nausea, vomiting, and loss of appetite.
  • Kidney Problems: High levels of calcium in the blood can lead to kidney stones, kidney damage, and impaired kidney function.
  • Bone Pain: Paradoxically, too much vitamin D can lead to bone pain and weakness, as excess calcium can be deposited in the bones.
  • Heart and Blood Vessel Issues: Hypercalcemia can affect the heart and blood vessels, leading to irregular heartbeats and other cardiovascular problems.
  • Growth Retardation: Ironically, excessive vitamin D intake can negatively impact growth by affecting the normal balance of minerals and hormones necessary for bone development.

It’s important to note that vitamin D toxicity is rare and usually occurs from extremely high doses of supplements. The recommended daily intake for vitamin D varies based on age and individual needs. Generally, it’s advisable to consult with a healthcare professional before giving children vitamin D supplements, especially if they are already receiving adequate vitamin D from sunlight exposure and their diet.

In conclusion, while vitamin D is crucial for children’s growth and health, maintaining a balance and avoiding excessive supplementation is essential to prevent potential adverse effects.


How to get vitamin D?

Here are the top ways to get enough vitamin D for your children.

Sunlight and Vitamin D Synthesis

Vitamin D is commonly known as the sunshine vitamin due to its primary source being sunlight. For children, exposure to sunlight on their skin is essential for synthesizing vitamin D, fulfilling approximately 80% of their vitamin D requirement. Nevertheless, several factors impact the amount of vitamin D they can generate from sunlight, including:

Skin Exposure: The extent of skin exposed to the sun directly affects the amount of vitamin D produced. For instance, exposing larger areas like the back facilitates more vitamin D synthesis compared to limited exposure like the face and hands.

Time of Day: Optimal vitamin D production in the skin occurs around noon when the sun is at its peak. However, extended sun exposure can be harmful, necessitating sunscreen application and proper hydration.

Skin Pigmentation: Notably, lighter skin is more efficient in synthesizing vitamin D compared to darker skin.

A brief period of sun exposure can provide adequate vitamin D for the day. Lighter-skinned individuals might need around 15 minutes, while those with darker skin might require a few hours. These recommended durations hold true for children spending time outdoors. It’s crucial to emphasize that excessive sun exposure can lead to sunburn, skin damage, and even skin cancer. Therefore, utilizing sun protection measures such as sunscreen and appropriate clothing is imperative to safeguard the skin while enjoying outdoor activities.

Vitamin D-rich foods

Consuming vitamin D-rich foods can be especially beneficial if your children do not get much sun exposure or have dark-colored skin. Although there are not many foods that are naturally high in vitamin D, we have listed some.

  • Foods naturally high in vitamin D
