Vitamin D for Children

It is important that children are receiving an adequate amount of vitamin D to build strong bones and teeth, support muscle function, neurotransmission, and cell division. Vitamin D deficiency in children can cause rickets, a severe disease that affects bone development, and can cause bone pain, poor growth, as well as soft, weak bones that can lead to bone deformities.

What is vitamin D?

Vitamin D is a type of fat-soluble vitamin. Fat-soluble vitamins refer to the vitamins that are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamin D plays a key role in numerous important bodily processes. This includes helping the body absorb other nutrients, ensuring that muscles and bones work efficiently, regulating neurotransmitter synthesis, helping to support the immune system, supporting heart health, as well as regulating insulin levels.  


How can I ensure that my child is getting enough vitamin D?

Vitamin D is sourced primarily from the sun (we obtain approximately 80-90% of it this way). It is seasonal and cannot be made during the winter, while the amount made in the summer is subject to sunshine, weather, and other factors. In Ireland, it can be produced from 10-15 minutes of sun exposure from late March to late September.

Vitamin D can also be found in some foods. This includes mackerel, salmon, sardines, herring, tuna, red meat, liver, fortified foods (breakfasts cereals, dairy products, orange juice, infant formulas), egg yolks, as well as mushrooms that have been grown in ultraviolet light (shiitake mushrooms, portobello mushrooms).

The best way to ensure that your child is receiving the recommended intake of vitamin D is through supplementation.
