Every parent wants to give their child a real health boost—but with so much conflicting advice, it’s hard to know what truly works.
The truth? Nutrition is the foundation. Missing even one key nutrient can impact your child’s growth, immunity, and cognitive development.
This guide covers the 10 most critical nutrients backed by science—so you can be confident your child is getting what they need.
1. Vitamin D: The Sunshine Vitamin for Strong Bones
Why it matters:
- Supports bone development and immune function.
- Deficiency is linked to weaker immunity and slower growth.
Best sources:
- Fatty fish (salmon, mackerel)
- Fortified milk or dairy alternatives
- Egg yolks
For kids who don’t get enough sunlight, a vitamin D3 supplement like Nordic Naturals Vitamin D3 Gummies can help maintain optimal levels.
2. Iron: Essential for Energy & Brain Power
Why it matters:
- Prevents fatigue and poor concentration.
- Critical for cognitive development.
Best sources:
- Lean meats (beef, chicken)

If your child is a picky eater, an iron-fortified cereal or a gentle liquid iron supplement like Floradix Iron + Herbs may be beneficial.

Why it matters:
- Supports brain development and focus.
- Reduces inflammation and allergies.
Best sources:

Why it matters:

- Helps muscle and nerve function.
Best sources:

If dairy isn’t an option, calcium-enriched almond milk or a children’s calcium chewable can fill the gap.
