Colds or the common cold is a viral infection of the upper respiratory tract. It is a viral infection that causes symptoms, such as cough, runny nose, congestion, and sore throat.

The symptoms of colds can range from mild to severe and can last from a few days to a few weeks.

As parents, it is hard to see our children sick, so finding treatments that work is essential. Vitamin D is a vital nutrient that our bodies need to function, and some studies suggest that it may play a role in fighting off the cold virus.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that is essential for good health. It helps to promote strong bones, supports immune function, and helps to regulate calcium and phosphorus levels in the body.

Our bodies naturally produce Vitamin D when exposed to sunlight, but it can also be obtained from food sources, such as fatty fish and fortified foods like milk and cereal.

Various studies have found that Vitamin D may play a role in the prevention and treatment of respiratory illnesses, including the common cold.

Researchers theorize that Vitamin D helps to strengthen the immune system, allowing it to better fight off infections.

Some studies have also found that people with low levels of Vitamin D are more likely to experience upper respiratory tract infections, such as the common cold.

The Evidence

A 2017 study published in the British Medical Journal found that daily or weekly Vitamin D supplementation reduced the risk of acute respiratory tract infections, including the common cold, by about 12%.

The study included data from 25 randomized controlled trials with more than 11,000 participants.

Another study published in the Journal of Investigative Medicine found that Vitamin D may help to boost immune function by increasing the production and activity of antimicrobial proteins. These proteins help to kill viruses and bacteria.

A 2012 study published in the Journal of Pediatrics found that children with higher levels of Vitamin D in their blood were less likely to experience respiratory infections, including the common cold.

How much Vitamin D is needed?

The recommended daily intake of Vitamin D varies depending on age and other factors. According to the National Institutes of Health (NIH), the recommended daily intake of Vitamin D for children aged 1-18 is 600 IU.

However, some experts suggest that higher daily doses may be needed to see the benefits of Vitamin D on colds and other respiratory infections.

Conclusion

While more research needs to be done, the evidence suggests that Vitamin D may be effective in treating colds in children.

The best way to ensure that your child is getting enough Vitamin D is to encourage sun exposure, eat a healthy diet rich in Vitamin D, and consider supplementation if your child is not getting enough through diet and sunlight.
