Frequently Asked Questions
Are electrolyte sticks safe for kids?
Most single‑serve sticks are safe for school‑age children when used as directed. Check the sodium content if your child is very young or has a medical condition, and consult your pediatrician for children under age 4 or if you have concerns about sodium or other ingredients.
How many sticks should my child use after practice?
Typically one stick mixed into the recommended water volume is enough after a normal practice. For longer, sweatier sessions allow additional fluids and snacks; follow product dosing and consult a healthcare provider if unsure.
Can I mix sticks into small sports bottles?
Yes — most sticks mix into 16–40 oz of water. Mixing in smaller bottles concentrates flavor and electrolytes, so use a lower water volume for stronger taste or more for milder flavor. Shake well until dissolved.
