Vitamin D requirements in children: for healthy growth

Vitamin D, often referred to as the “sunshine vitamin,” is crucial for children’s development. However, many children suffer from a deficiency in this essential vitamin. Understanding vitamin D requirements in children is essential to ensure their long-term health.

Why is vitamin D important for children?

Vitamin D plays a crucial role in several aspects of child development, including:

  1. Bone health: It promotes the absorption of calcium and phosphorus, necessary for healthy bone growth and the prevention of rickets, a disease that weakens bones in children.
  2. Immune system: Studies have shown that vitamin D plays a role in the optimal functioning of the immune system. A vitamin D deficiency can make children more susceptible to infections.
  3. General health: In addition to its role in bone and immune health, vitamin D is also associated with children's cardiovascular and mental health, making it a crucial nutrient for their overall well-being.

Vitamin D requirements in children

  1. Infants: Breastfed infants require vitamin D supplements from the first days of life because breast milk does not provide enough. Bottle-fed infants should use a formula enriched with vitamin D to meet their needs.
  2. Older Children: For older children, a balanced diet is essential to get enough vitamin D. Foods rich in vitamin D include fatty fish such as salmon and tuna, eggs, dairy products or plant-based drinks enriched, as well as cereals. In addition, moderate exposure to the sun is recommended to promote the synthesis of vitamin D in the skin. However, it is crucial to protect children's skin from harmful UV rays by using sunscreen and limiting exposure time during the hottest hours of the day.
  3. Sun exposure: Moderate exposure promotes vitamin D synthesis in the skin, but it is important to protect the skin from harmful UV rays by using a children's sunscreen with an adequate SPF. Find our advice here .

Signs of vitamin D deficiency in children

Signs such as bone pain, failure to thrive, bone fragility, fatigue, or muscle weakness may indicate vitamin D deficiency in children. If you observe any of these symptoms in your child, it is important to consult a healthcare professional for appropriate screening and advice.

Beware of overdose: always respect the recommended dosages

While a vitamin D deficiency is a concern, it is also crucial not to overdose on this vitamin. Too much vitamin D can cause hypercalcemia, too high a level of calcium in the blood, which can lead to serious health problems. It is therefore important to strictly follow the dosages recommended by a healthcare professional.
