The Formula

Most shakes hide eighteen ingredients.
We use five.

01 / 05
01
Water

The base of everything here. Nothing hidden inside it.

Plain water, nothing added. It just carries the aminos, flavor, and trace minerals in the rest of the list.

02
Essential Amino Acids

The building blocks your muscles use to repair and grow.

Nine essential amino acids, fermented from real vegetables. Your body can't make them, so they have to come from food or drink. They are what your muscles use to repair.

03
Citric Acid

Keeps the drink fresh, from lemons only.

Its job is to keep the drink fresh over time. Ours comes only from lemons. Most packaged foods use a corn or mold version instead.

04
Lemon Extract

Real lemon flavor, straight from the fruit.

This is where the tart lemon taste comes from. We use real lemon extract instead of a lab-made flavor, so it tastes closer to fruit you squeezed yourself.

05
Organic Shiitake Extract

Adds a few natural trace minerals and depth.

Organic shiitake mushroom extract adds small amounts of natural minerals and a little depth. With the minerals already in water, it gives a light electrolyte content.

Nine amino acids do the work

0

Muscle, recovery, repair all run on amino acids. Protein is how they arrive, and the nine your body cannot make are the essential ones.

Most people already eat enough protein. Fewer get those nine in a ratio the body can use.

Our Story

Why we made this

One stem, five ends. The short version of how a lemon protein water ended up with only five ingredients, and why we left the rest out.

The problem

Real food doesn't always fit the day.

Long days leave long gaps between meals. There is rarely time to eat well.

The fallback

So you grab a bar or a shake.

They help in a pinch. But most are candy in disguise, and slowly replace real meals.

The bigger drift

It happens off the plate too.

Phones & feeds pull us from real talk, real movement, real time outside. It's the same swap.

The protein push

You already get enough protein.

Brands push protein, but most get enough. Fiber is the next push, and we need ours from food.

The real gap

What most people miss is hydration.

Plenty of us fall short on water. It gets far less attention than a big protein number.

Easy to overlook

Amino balance is easy to miss.

Essential aminos: food only. Vegans & restricted eaters can miss it, even with enough protein.

The restraint

We left things out on purpose.

No whey, no sweeteners, no sugar, fat, or carbs. No dairy, egg, soy, or nuts.

The bottle

Bottled in glass.

Glass is 100% recyclable, unlike aluminum or plastic, and we don't use plastic caps or paint.

The design

Water first, then the amino acids.

It drinks like water with a lemon kick, and stays light instead of sitting heavy like a shake.

Back to real

Real food still comes first.

Drink it between meals or with one. It fills a gap, then gets out of the way.

The mission

The healthier choice, made easier.

All from the earth: water, shiitake, lemon, aminos. When real food isn't around. When it is, eat it.

None of this is complicated. Take out what doesn't need to be there, keep what does, and don't hide the difference. Five honest ingredients beat eighteen you can't pronounce.
