Why we're making it

Made for a daily routine, not a chore.

Most inositol powders are unflavored or taste like medicine, clump, or leave grit at the bottom of the glass. We're building Fortyone to be the one you actually want to drink: light flavor, no bitter sweetener aftertaste, fully dissolved in cold water.

Tastes like a drink

Lightly flavored and lightly sweet. We're choosing the launch flavor with blind taste tests.

Dissolves completely

Our spec: fully dissolved in cold water within 30 seconds of shaking, with no sediment.

Simple formula

Two inositols, plus magnesium, vitamin C and light electrolytes. Every amount on the label, listed below. No herbs, no caffeine, no blends.

Planned formula

Every amount on the label.

These are the planned amounts we're sampling now, per stick. The final label may differ slightly, and we'll publish it before launch.

Not included: caffeine, herbs, collagen, berberine, proprietary blends.
