The arrival of a new baby brings immense joy to the family, and after a period of observation, doctors usually recommend supplementing the baby with vitamin D. But how do you properly supplement vitamin D for your child to ensure they’re getting the right amount?

Vitamin D plays a crucial role in helping the body absorb calcium and promoting healthy bone development. It's especially important for growing children. But how much vitamin D does your child need? And how can you provide the right dosage for each stage of their growth? Let’s break it down by age group.

1. Infants (0-12 Months)

Recommended Dosage: 400 IU per day

Supplement Form: Infant formula usually contains 400 IU of vitamin D per liter, so if your baby consumes at least 32 ounces of formula a day, they’re likely getting enough vitamin D. However, breastfed babies, or babies consuming less than 32 ounces of formula daily, need additional vitamin D supplementation. Liquid vitamin D drops are the best option for infants and can be administered directly into the baby’s mouth or mixed with milk.

The Takeaway: For breastfed babies, be sure to supplement with liquid vitamin D drops to support their bone health.

2. Toddlers (1-3 Years)

Recommended Dosage: 600 IU per day

Supplement Form: For toddlers, you’ll find vitamin D supplements in both chewable tablets and liquid forms. The choice largely depends on your child’s preferences. If they have trouble chewing tablets, liquid drops are a great alternative.

Key Takeaway: Choose a supplement that suits your toddler's preference—chewable tablets or liquid drops. Ensuring they get the right dosage is key to supporting their growth.

3. School-Age Children (4-8 Years)

Recommended Dosage: 600 IU per day (some children may need a higher dosage, such as 600-1000 IU, based on a doctor’s advice)

Supplement Form: At this age, children can easily chew tablets or swallow pills. There are many fun and tasty chewable tablets and gummies that appeal to children. Choose the form that works best for your child.

Final Thoughts: With tablets, gummies, and liquid options, you can find a vitamin D supplement that’s both effective and enjoyable for school-age children.

4. Teenagers (9-18 Years)

Recommended Dosage: 600-1000 IU per day (the exact dosage may vary depending on your teenager’s health and your doctor’s recommendations)

Supplement Form: Teenagers can take vitamin D supplements in tablets, capsules, or gummy forms. If your teenager doesn’t like swallowing pills, gummies or chewable tablets are an excellent alternative.

Key Takeaway: Encourage your teenager to take vitamin D supplements that match their preference—whether it’s gummies or tablets.

Important Considerations

  • Follow Medical Advice: Always consult your child’s doctor if they have specific health conditions (like obesity or bone disorders) before deciding on the correct dosage. Your doctor may recommend a higher dosage based on your child’s needs.
  • Choosing Supplements: With so many supplement options available, choose one that fits your child’s age, dosage requirements, and flavor preferences. Be sure to check that the supplement has the recommended amount of vitamin D for your child’s age.

The Takeaway: Careful consideration of your child’s needs, along with the guidance of your healthcare provider, ensures the right vitamin D supplementation to promote your child’s healthy development.
