Metabolic Support, Done Right

Most “blood sugar” supplements sprinkle in cinnamon and call it science. FitFast does not.

This professional-grade formula combines clinically dosed berberine with InSea2®, a patented seaweed polyphenol blend, to support how your body handles carbs, especially after meals. No filler blends. No questionable sourcing. Just research-backed ingredients for people who actually read the label.

Planning meals is step one. This is step two.

Made for People Who Want Better Balance After Meals

FitFast is designed for anyone looking to feel steadier, more in control, and less affected by the highs and lows that can follow carb-heavy foods.

  • Who It’s For:

    • People who want support for a healthy glycemic response to everyday meals
    • Anyone who feels sluggish or mentally foggy after eating carbs
    • Individuals looking for a natural, research-backed approach to metabolic wellness
    • Those building a routine to support more stable daily energy

  • Who It’s Not For:

    • Anyone expecting quick-fix results without consistent use
    • Those looking for a stimulant-based energy boost
    • People who prefer sugary or flavored metabolic products
    • If you’re not willing to take supplements before meals, this won’t fit your routine

What’s Inside (And Why It Works So Well Together)

Research-backed ingredients that support healthy carbohydrate metabolism and post-meal glycemic balance, without stimulants or unnecessary fillers.

Berberine HCL

A time-honored botanical known for supporting healthy metabolic function and healthy blood sugar levels already within the normal range.

InSea2 Brown Seaweed Extract

A clinically researched polyphenol complex shown to support a healthier glycemic response to carbohydrate-rich meals.

Chromium (TRAACS®)

Highly bioavailable chromium to support healthy carbohydrate metabolism and insulin function.

Formulated to exclude: wheat, gluten, yeast, soy, animal and dairy products, fish, shellfish, peanuts, tree nuts, egg, ingredients derived from genetically modified organisms (GMOs), artificial colors, artificial sweeteners, and artificial preservatives.

Other ingredients include: capsule (hypromellose and water), magnesium stearate, and silica.

How FitFast Typically Supports Your Day

  • Day 1

  • Week 1

How to Use FitFast

  • Take 1 capsule twice daily before meals
  • For larger or higher-carbohydrate meals, take shortly before eating
  • Pair with consistent diet habits for best results

Use daily as part of your metabolic and nutritional routine. Taking FitFast before meals helps support a healthy glycemic response.

Pro Tip: If you’re new to berberine or metabolic support supplements, start with one capsule per day and gradually increase to the recommended serving.
