For your child's immune defense, this gummy delivers key nutrients at meaningful pediatric doses. Per 2-gummy serving, your child gets **Vitamin D** at 800 IU — well above the 400 IU pediatric guideline and in the range studied for reducing respiratory infections in children. **Vitamin C** at 90 mg fully covers a child's daily needs.
**Zinc** provides 3.6 mg, which covers about half the RDA for children ages 4-8. What this means for you: the 100 mg of **Black Elderberry Extract** is a common immune addition, though clinical data in pediatric populations is limited.
Keep in mind the directions recommend just 1 gummy for 3-year-olds, which cuts every dose in half. At that single-gummy serving, your child still gets a solid 400 IU of vitamin D but only 1.8 mg of zinc — a fairly modest amount. For children age 4 and up taking the full 2 gummies, the doses are more meaningful.
