What Daily Nutrition Should Cover

Protein is the easy part. FitFuel covers the rest. The Fitties Vegan Protein Blend brings 21g of complete plant protein with an amino acid score of 100%, and Aminogen enzymes help you absorb it. Then it goes where most shakes don’t: a colostrum-based immune blend with immunoglobulins to support immune function, truebroc glucoraphanin to support natural detoxification, and arabinogalactan fiber for intestinal health. The immune blend contains milk, so FitFuel isn’t vegan, but it does more than almost any shake on the shelf.

Who FitFuel Is For

Built for people who want their daily shake to do more than build muscle.

  • Who It’s For:

    • Anyone who wants a complete daily nutrition shake, not just a protein
    • People focused on supporting their gut, immune system, and natural detox

  • Who It’s Not For:

    • Vegans or anyone avoiding dairy, since the immune blend contains milk (try FitPlant+)
    • Anyone who just wants a simple, low-sugar protein without the extra ingredients

Frequently Asked Questions

What kind of protein is in FitFuel?

FitFuel uses the Fitties Vegan Protein Blend, a plant-based blend of pea and rice protein, providing 21g of complete protein per serving with an amino acid score of 100%.

Is FitFuel vegan?

No. While the protein is plant-based, FitFuel includes a colostrum-derived immune blend that contains milk, so it is not vegan or dairy-free. If you want a fully vegan protein, see FitPlant+.

How does FitFuel support immunity?

It includes a 2.5g immune blend of immunoglobulins from colostrum, which support immune function. These come from milk.

What does FitFuel do for detox?

FitFuel includes truebroc glucoraphanin, a compound from broccoli seeds that supports your body’s natural detoxification processes.

Does FitFuel support gut health?

Yes. It includes arabinogalactan and inulin, prebiotic fibers that support intestinal health and feed the beneficial bacteria in your gut.

Does FitFuel contain sugar?

FitFuel has 5g of added sugar from dried cane syrup and is also sweetened with stevia. It’s fructose-free, but it isn’t a no-sugar formula like FitWhey+ or FitPlant+.

How is FitFuel different from FitPlant+?

FitPlant+ is a fully vegan protein with a full multivitamin. FitFuel is a functional daily shake that adds immune, detox, and gut support, but it contains milk and isn’t vegan.

How do I use FitFuel?

Blend or shake two scoops into 10-14 oz of chilled water, one to two times daily. If you take medication or have health concerns, check with your healthcare provider first.

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 goes through independent third-party testing to verify purity, potency, and identity before it ever reaches your hands. No hidden extras. No low-grade shortcuts. Just ultra-premium, research-backed ingredients that are formulated to match exactly what the label says.

Where are Fitties products made?

All Fitties supplements are manufactured in the USA in cGMP-certified, FDA-registered facilities. We don’t outsource quality. We build everything to the highest standard because your health and performance deserve nothing less.

Are Fitties supplements vegan, gluten-free, or allergen-friendly?

Each product is different, and we call out all dietary details clearly on every product page. Many formulas are vegan, gluten-free, dairy-free, or soy-free, and we never use artificial dyes or cheap fillers. If something doesn’t fit your dietary needs, you’ll know upfront.
