Fall for U Sale is live. ๐Ÿ

Summer belonged to everyone else. September is the first month that's yours again.

It's about U.

Seasons change. What doesn't is the small thing you do every day that supports U, the kind you don't often think twice about.

13 years ago, we introduced a premium marine collagen peptides to a market that didn't really know what they were yet. We figured the rest out as we went, growing from a small, basement startup to where we are today, because U kept showing up, and we're grateful U brought your family and friends along too.

We never take that for granted. Fall For U, our fall sale, is how we say thank you. ๐Ÿค

VIPs your early access starts Thursday, Sept. 17.
Fall For U runs September 18โ€“22. ๐Ÿ”— in bio.

It's about U.

No sugar. Too much sodium. Or just right?

There's 1 gram of functional organic cane sugar in our ReHydrate, and it's the question we get asked most.

The 1g of sugar is there for a reason. Sodium absorbs better when there's a little glucose with it. The two cross into your bloodstream together and water follows them in.

Take the sugar out entirely and you lose that support.

Twenty times less sugar than a sports drink, and far less salt than most electrolytes on the shelf. It isn't there for sweetness.
The rest of the formula follows the same thinking.

Organic Lemon was the first ReHydrate we made, back in 2018, and it's still the one in many of our customer's glass every morning. ๐Ÿ‹

Made in Canada, woman owned, independent since 2013.

What flavour should we make next? ๐Ÿ‘๐Ÿ‹๐Ÿ‰๐ŸŠ๐Ÿ๐Ÿ‹โ€๐ŸŸฉ
