Mission

Mersea optimizes kids' hydration with carefully selected ingredients and formulas their families can trust. Every product is crafted to meet the nutritional needs of growing bodies, with full ingredient transparency and no shortcuts on quality.

Mersea started with two moms...

with a shared commitment to better options for their families.

Molly, a registered dietitian, and Caroline, a certified health coach, brought their expertise together with a goal to create a hydration product they would truly feel good about giving their kids.
