Shelf-stable sea moss, finally. Homemade and store-bought sea moss gels need refrigeration and spoil within weeks. Mersea is the only sea moss + kelp supplement for kids that needs no fridge before or after opening, because every pouch is a single, sealed 15 mL serving.
Inside: balanced electrolytes (sodium, potassium, magnesium, calcium) to replace what active kids lose, organic Irish sea moss and kelp for naturally occurring trace minerals and a measured 90 mcg of iodine, plus vitamin C from organic acerola.
Sweetened with organic honey. <1 g added sugar per squeeze.
Formulated for kids ages 4 and up — one 15 mL pouch daily, or as directed by a healthcare professional. Big kids (and parents) love it too.
Pufferfish Peachy Mango: naturally sweet, fruity and smooth, like a peach-mango gel snack. No fishy or seaweed taste, no artificial flavors, colors or sweeteners.
Shelf-stable at room temperature, so there is nothing to refrigerate and nothing to finish before it spoils. USDA Certified Organic. Made without milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame, GMOs, MSG or gluten. No artificial dyes.
The ocean's minerals, no fridge required
Sodium, potassium, magnesium and calcium (HYDRA 4G™) in amounts sized for growing bodies.
100 mg organic Irish sea moss and 90 mcg of kelp iodine, sealed in a single-serve squeeze that never needs a fridge.

How to use
Tear the top off one Pufferfish Peachy Mango squeeze.
Squeeze it straight into their mouth — no water, no scoop, no shaker.
One a day: before practice, after school, on the plane, or on a sick day.
Only from Mersea
Sea moss is everywhere, but almost all of it comes as a gel in a jar: soak, blend, refrigerate, and use it up within a couple of weeks before it spoils. Mersea is different. Organic Irish sea moss and organic kelp are measured into a sealed, single-serve 15 mL squeeze that stays fresh at room temperature until your kid tears it open. No jars. No ice packs. No fridge. Ever.
Sports drinks are packed with added sugar and artificial dyes. Sea moss gels need a refrigerator and a spoon. Mersea gives kids balanced electrolytes and real sea minerals in a naturally sweet peachy-mango squeeze with less than 1 g of added sugar, no dyes, and nothing to keep cold.
No powder. No measuring. No fridge to remember. Because Mersea is shelf-stable, a squeeze lives happily in a lunchbox, sports bag, beach tote or carry-on until it's needed. The sea's minerals, wherever your kid goes.

FAQs
Everything parents ask us before their first box, starting with the fridge question.
Yes. Sea moss is normally sold as a gel that has to be refrigerated and used within a few weeks, or as adult-dosed capsules and powders. Mersea is the only kids' sea moss + kelp supplement in a sealed, single-serve, shelf-stable squeeze. It stays fresh at room temperature until you open it, and because each pouch is one serving there is nothing left over to store.
No, and that's the whole point. Mersea is shelf-stable, so it can live in a backpack, glovebox or lunchbox for months. Some families like it chilled as a treat, but it's never required.
Organic Irish sea moss is naturally rich in trace minerals, and organic kelp is a natural source of iodine, which supports normal growth and metabolism. We measure both so every squeeze delivers 100 mg of sea moss and 90 mcg of iodine, no guesswork.
Mersea Hydration Squeeze is formulated for children ages 4 and older. Adults can absolutely enjoy it too, but the formula is sized for kids.
One 15 mL pouch per day, or as directed by a healthcare professional. Many families make it part of the morning routine or pack it for practice.
Before or after sports and play, on hot days, during travel, on sick days, or any time your kid is running low on water. It also makes a great naturally sweet treat.
No. It’s a ready-to-eat gel squeeze designed to support hydration and deliver minerals many kids miss in their diets, without the sugar and dyes found in most sports drinks.
No artificial dyes, flavors or sweeteners. Made without milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame, GMOs, MSG or gluten.
