Which vitamins does my child really need?
With so many supplements available, it can feel overwhelming to know what’s truly necessary and what’s not.
The good news is that most babies and young children can get what they need from a healthy, balanced diet. However, there are a few key nutrients that often deserve special attention—especially during the early years of growth and development. This guide highlights the most important vitamins commonly recommended to support infants and young children.
Vitamin D
Vitamin D is essential for strong bones and healthy growth. While sunlight helps the body produce vitamin D, the amount of sun exposure required may increase the risk of skin damage. At the same time, dietary sources of vitamin D are limited, especially for infants.
For this reason, pediatric guidelines recommend that all infants and children receive 400 international units (IU) of vitamin D daily, starting shortly after birth. This is particularly important for babies who are exclusively or partially breastfed.
Infant formula is typically fortified with enough vitamin D, so babies who consume adequate amounts may not need additional supplementation. However, many infants and young children still benefit from vitamin D drops to help prevent conditions like rickets—a disorder that causes soft, weak bones due to vitamin D deficiency.
Vitamin C
Vitamin C plays a vital role in immune health, wound healing, and bone development. It also acts as an antioxidant and improves iron absorption from food.
Most children who eat a varied diet rich in fruits and vegetables receive enough vitamin C naturally. However, certain factors—such as exposure to cigarette smoke—can increase a child’s vitamin C needs.
Although vitamin C deficiency is rare, low levels can lead to fatigue, poor wound healing, joint pain, and gum issues. If a child is at risk, supplementation may be considered under the guidance of a healthcare professional. It’s important to follow age-appropriate dosing to avoid excessive intake.
DHA (Omega-3 Fatty Acids)
DHA, a type of omega-3 fatty acid, is an important building block for brain and nervous system development. It plays a role in cognitive function, learning, and behavior.
While research is still evolving, some studies suggest that DHA supplementation may support attention, learning, and overall brain health in children—particularly if dietary intake is low. DHA is naturally found in fatty fish, but many children don’t consume enough of these foods, making supplementation a consideration for some families.
Always consult your pediatrician before starting DHA to determine whether it’s appropriate for your child.
Multivitamins
For older children, a daily multivitamin can help fill nutritional gaps—especially for picky eaters or children who avoid certain food groups, such as dairy or vegetables.
That said, most children who eat a balanced diet do not need a multivitamin. Supplements should complement healthy eating, not replace it.
Parents should always store vitamins safely out of reach and clearly explain that vitamins are medicine—not sweets. Taking more than the recommended amount can be harmful, so supervision is essential.
Final Thoughts
Every child is unique, and vitamin needs can vary based on diet, lifestyle, and health factors. Before starting any supplement, it’s always best to consult your pediatrician to ensure it’s necessary and appropriately dosed.
