Berberine Is Only Half the Formula.

When an ingredient gets popular, the market floods with cut-rate versions, and berberine is the latest example. The studies that earned berberine its reputation used roughly a gram a day; a lot of what’s on the shelf delivers far less. FitFast holds the full dose and pairs it with InSea2, a brown seaweed blend that goes after the carb-digesting enzymes in your gut, so you’re supporting a healthy glycemic response from two directions instead of hoping a half-dose of one ingredient does the job.

Who FitFast Is For

Built for people who want real support for how their body handles the carbs they eat.

Who It’s For:
Anyone who wants to support a healthy glycemic response to the carbs in their diet
People already taking berberine who want a properly dosed version with more behind it
Who It’s Not For:
Anyone looking to treat a blood sugar condition, since this is everyday glycemic support, not medical care
People on medication or managing a health condition who haven’t checked with their doctor first

What’s Inside

Three ingredients, properly dosed, each with a job to do. No filler standing in for a formula.

Berberine HCL

500mg per capsule, a full 1,000mg a day, the clinically studied dose rather than the sprinkle most berberine supplements settle for. The cornerstone of the formula.

InSea2

A clinically studied brown seaweed blend that targets alpha-amylase and alpha-glucosidase, the carb-digesting enzymes, supporting a healthy glycemic response to your meals.

TRAACS® Chromium

A highly absorbable, chelated form of chromium, a trace mineral that supports healthy glucose metabolism, and the same pairing studied alongside InSea2.

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.

What to Expect From FitFast

Part of FitFast works on your next meal, part of it builds over time. Here’s the honest version.

From Day 1
Take a capsule before a meal and InSea2 gets to work on that meal right away, targeting the enzymes that turn its carbs into glucose. The per-meal piece starts immediately.
Weeks 4-12
With consistent daily use, berberine’s support for healthy glucose metabolism builds in the background. This is the steady, cumulative side of the formula.
Ongoing
Glycemic support is a habit, not a one-time fix. It works best taken consistently before meals, alongside a balanced diet.

How to Use FitFast

Take 1 capsule
Twice a day, before meals

Every day, before two of your main meals. About 15 to 30 minutes before eating, so it’s working when the carbs arrive. Berberine can interact with medications. Check with your healthcare provider first if you take any, or if you’re pregnant or nursing.

Pro Tip: Take it before your highest-carb meals to get the most out of the InSea2.

How FitFast Compares

Most berberine supplements give you a fraction of the studied dose and call it a metabolism product. FitFast is the full amount, plus a second ingredient that works on your meal. It’s the dose and the design.

Frequently Asked Questions

What is berberine?

Berberine is a naturally occurring plant alkaloid used traditionally and studied for supporting healthy blood glucose metabolism. FitFast provides berberine HCL at 500mg per capsule, 1,000mg a day at the full serving.

How much berberine is in FitFast, and why does the dose matter?

FitFast provides a full 1,000mg of berberine a day, the amount used in research. Many berberine products contain far less, which is why the dose on the label matters as much as the ingredient itself.

What is InSea2 and what does it do?

InSea2 is a clinically studied blend of polyphenols from two brown seaweeds. It works on alpha-amylase and alpha-glucosidase, the enzymes that digest starch and sugar into glucose, supporting a healthy glycemic response to the food you eat.

What does FitFast do?

FitFast is formulated to support a healthy glycemic response to foods and to help support healthy blood glucose levels, in generally healthy people, by combining berberine, InSea2, and chromium.

When and how should I take it?

Take one capsule twice daily, about 15 to 30 minutes before meals, so the ingredients are working as your food is digested. Taking it before higher-carb meals makes the most of the InSea2.

Is FitFast for diabetes or high blood sugar?

No. FitFast is a dietary supplement formulated to support a healthy glycemic response and healthy blood glucose levels in generally healthy people. It is not intended to diagnose, treat, or manage diabetes or any blood sugar condition. If you have one, work with your healthcare provider.

Can I take FitFast with medication?

Berberine can interact with a number of medications, including some that affect blood sugar. If you take any medication, have a health condition, or are pregnant or nursing, talk to your healthcare provider before using FitFast.

Is FitFast vegetarian and allergen-friendly?

Yes. FitFast uses vegetarian capsules and is made without gluten, soy, dairy, GMOs, and artificial additives.

Can I stack Fitties products together?

Yes. All Fitties supplements are formulated with complementary ingredient profiles, so they can be used as part of the same daily routine. If you want a ready-made stack, our curated bundles pair the right products for strength, performance, recovery, and overall health so you don't have to guess.

Are Fitties products third-party tested?

Yes. Every Fitties formula is made in an NSF-certified GMP facility and tested for purity, potency, and identity. No low-grade shortcuts. Just ultra-premium, research-backed ingredients, every one listed on the label.

Where are Fitties products made?
