Essential Vitamins Your Kids Need at Every Age

About

Ensuring children receive the right nutrients is essential for their learning, growth, and overall development. For many children, breastfeeding or formula-feeding in infancy, followed by a balanced diet during their toddler years and beyond, suffices to meet their nutritional needs. However, some children, particularly those with picky eating habits or specific health issues, may require supplements or specialized nutritional support to stay well-nourished.

Your pediatrician and a pediatric registered dietitian nutritionist (RDN) can guide you in understanding your child's unique nutritional requirements. They can also recommend tools and strategies to help your child get the essential vitamins and minerals they need to thrive. Here is a comprehensive guide to the top nutrients children need at every age.

Are Your Kids Getting Enough of These Essential Nutrients?

Children require a variety of vitamins and minerals, but six key nutrients stand out for their importance: vitamin D, iron, omega-3s, zinc, calcium, and potassium. Here’s how to ensure your child consistently gets these nutrients.

• Toddlers and young children: As children begin to eat more varied foods, they may not require a supplement. However, consultation with a pediatrician is recommended.
• Older children and teenagers: They need 600 IU per day. Periodic checks of their vitamin D levels can determine if supplementation is necessary(2^✔ ✔Trusted Source
