Vitamin D for Toddlers

person

Prof. Liam Chen

Austvita Expert

Vitamin D plays a crucial role in calcium absorption and bone mineralization — both essential during the rapid growth period of toddlerhood. Despite Australia's abundant sunshine, many toddlers don't get enough.

Why Toddlers Need Vitamin D

During the first three years, your child's skeleton is developing at an extraordinary rate. Vitamin D ensures that dietary calcium is actually absorbed and deposited into growing bones and teeth.

How Much Do They Need?

The Australian recommended intake for children aged 1-3 is 400IU per day. Most toddlers get some from sunlight and fortified foods, but supplementation may be needed — especially during winter months.

Signs of Deficiency

Watch for delayed walking, bowed legs, muscle weakness, or frequent infections. If you suspect a deficiency, talk to your pediatrician about blood testing.

Our Recommendation

Austvita's Infant Multi-Vitamin Drops provide 400IU of Vitamin D3 per serve, combined with DHA and Iron for comprehensive daily support.
