Fuel Your
Gut.

Psyllium-husk fiber for people who move, train, and actually read the label. Every batch will be third-party tested and every COA published — honest enough to show its work.

The founding run is 100 pouches · numbered Nº 001–100 · yours for life

Our Story

Honest enough to
show its work.

Most fiber supplements feel like medicine — beige tubs, mystery blends, marketing that hopes you never flip to the back panel.

We built the opposite. FxF is psyllium-husk fiber for people who train hard and read labels harder. Every batch will be third-party tested and the results published — not because we have to, but because you'd ask, and you'd be right to.

Built for people who read labels.

01

Single ingredient

The Unflavored pouch is psyllium husk (seed husk). That's the whole list. No fillers, no fake colors, no proprietary blends to hide behind.

02

Scan the proof

Every batch will be third-party tested for heavy metals, and every COA published. Each pouch will carry a QR to its own batch results — so you can scan the proof and read it yourself.

03

Built for training

The Electrolyte drops add sodium, potassium, and magnesium — fiber that hydrates. Take it before or after you move, not just at the pharmacy counter.

What We're Launching

Fiber, and fiber that hydrates.

Unflavored ships this year, first to founding members. Tart Cherry and Lemon Lime — both with electrolytes — follow in 2027.
