Trace Minerals for Kids (Iodine, Selenium, Manganese): The Overlooked Nutrients That Matter

The “Silent Heroes” of Nutrition

When parents think of children’s nutrition, calcium, iron, vitamin D, and vitamin C often take the spotlight. Yet, there are trace minerals that are less discussed but equally vital for children’s growth and health: iodine, selenium, and manganese.

👉 Though required only in small amounts, these nutrients play a big role in growth, immunity, and brain development.

Iodine: Essential for Brain and Thyroid Health

• Role:

  • Supports thyroid hormone production, regulating growth and metabolism.

  • Plays a key role in brain development and cognitive function.

• Food sources:

  • Iodized salt, seafood, seaweed, milk, and dairy products.

• Deficiency risks: intellectual delays, thyroid disorders.

Selenium: The Antioxidant and Immunity Booster

• Role:

  • Functions as an antioxidant, protecting cells from free radical damage.

  • Strengthens the immune system and supports thyroid function.

• Food sources:

  • Seafood (tuna, shrimp, crab), Brazil nuts, eggs, whole grains.

• Deficiency risks: weakened immunity, higher risk of infections.

Manganese: Building Bones and Supporting Metabolism

• Role:

  • Helps in bone and cartilage formation.

  • Supports metabolism of carbohydrates, proteins, and fats.

  • Contributes to the production of antioxidant enzymes.

• Food sources:

  • Nuts, whole grains, soybeans, leafy greens.

• Deficiency risks: weak bones, developmental issues, delayed wound healing.

How to Ensure Kids Get Enough Trace Minerals

• Use iodized salt in daily cooking.

• Include seafood in weekly meals.

• Offer a variety of whole grains, nuts, and vegetables.

• Avoid over-reliance on supplements unless recommended by a doctor.

Iodine, selenium, and manganese may not be as well-known as calcium or iron, but they are crucial trace nutrients that support brain function, immune strength, and strong bones in children.

👉 A balanced, diverse diet is the key to ensuring kids receive these “silent heroes” of nutrition for healthy and complete development.
