Frequently Asked Questions
How do I tell if my child is dehydrated?
Watch for decreased urination or darker urine, dry lips/tongue, lethargy or irritability, fewer tears when crying, and dizziness. In mild cases offer fluids with electrolytes and rest; seek medical care if your child has persistent vomiting, high fever, rapid breathing, or very low urine output.
Are electrolyte powders and gummies safe for young children?
Many products are formulated specifically for kids with lower sodium and age-appropriate serving sizes. Always check the label for recommended ages and dosing, avoid giving adult-strength formulas to small children, and consult your pediatrician for infants under 1 year or if your child has medical conditions.
Can I rely on gummies alone to rehydrate my child?
Gummies provide electrolytes but contain little to no fluid, so they’re best as a supplement when a child won’t drink. For true rehydration, pair gummies with water or use a liquid electrolyte solution or powder mixed into water to replace both fluids and minerals.
