Benefits

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.

Key Nutrients

Sodium 45 mg · Potassium 60 mg · Magnesium 30 mg · Calcium 15 mg — the HYDRA 4G™ electrolyte blend
Iodine 90 mcg (60% DV) from organic kelp
Vitamin C 30 mg (30% DV) from organic acerola
Vitamin E 9 mg (60% DV)
Omega-3 ALA 500 mg from organic flaxseed oil
Organic Irish sea moss 100 mg (Chondrus crispus)

Sweetened with organic honey. <1 g added sugar per squeeze.

Age Range

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.

What does it taste like?

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 & Quality Standards

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 Only Shelf-Stable Sea Moss + Kelp Squeeze for Kids

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.

Shelf-stableSingle-serve100 mg sea moss90 mcg iodine

So Long, Sports Drinks (and Gel Jars)

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.

<1g added sugarNo artificial dyesNo refrigeration

Hydration Without the Hassle

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

We want you to ask questions!

Everything parents ask us before their first box, starting with the fridge question.

Contact us hello@wearemersea.com

Is Mersea really the only shelf-stable sea moss + kelp supplement for kids?

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.

Does it need to be refrigerated?

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.

Why sea moss and kelp?

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.

What ages is Mersea for?

Mersea Hydration Squeeze is formulated for children ages 4 and older. Adults can absolutely enjoy it too, but the formula is sized for kids.

How often should my kid have one?

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.

When is the best time to use it?

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.

Is this a sports drink?

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.

Does it contain allergens or artificial colors?

No artificial dyes, flavors or sweeteners. Made without milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame, GMOs, MSG or gluten.

What’s the full ingredient list?

Organic glycerin, purified water, organic honey, omega-3 ALA (from organic flaxseed oil), HYDRA 4G™ (calcium glycerophosphate, magnesium glycerophosphate, sodium citrate, potassium citrate), organic peach extract, organic vanilla extract, vitamin C (from organic acerola), organic mango extract, organic sea moss powder, vitamin E, organic sunflower lecithin, iodine (from kelp), malic acid, turmeric extract (for color).

What does it taste like?

Pufferfish Peachy Mango: naturally sweet, fruity and smooth. No fishy or seaweed taste.

How many squeezes are in a box?

Pick the size that fits your crew: the 30-ct box ($59.99) is a full month at one squeeze per day, and the 15-ct box ($29.99) is a two-week supply, perfect for trying Mersea or tossing in a travel bag. Every squeeze is a single-serve 15 mL pouch. The Duo Pack contains 60.

How does the subscription work?
