Not Just Another Protein Shake
Plant protein, immune, gut, and detox support in one shake, where most stop at one job.
Real Immune Support
2.5g of immunoglobulins, IgG and lactoferrin, for real immune support, not a vitamin C sprinkle.
Gut and Detox, Built In
Prebiotic fiber for your gut, plus glucoraphanin to support natural detoxification.
A Complete Plant Protein
21g of complete pea and rice protein, a 100% amino acid score, as the base.

One Scoop, Not a Shelf of Powders.

The daily-nutrition aisle runs on specialization: this one’s a protein, that one’s a greens blend, another’s just fiber or a stack of vitamins. FitFuel is built to cover more than one base in a single shake. It starts with 21 grams of complete plant protein at a 100% amino acid score, then layers in 2.5 grams of immunoglobulins for immune support, prebiotic fiber and arabinogalactan for your gut, and glucoraphanin from broccoli seed for detoxification support. It’s a functional food made for daily nutrition, the kind practitioners build protocols around, that does the work of several products at once.

Who FitFuel Is For

Built for people who want daily nutrition that does more than one thing, protein, immune, gut, and detox in one shake.

Who It’s For:
Anyone who wants daily nutrition that does more than one thing, protein, immune, gut, and detox in one
People who want real functional support, immunoglobulins and prebiotic fiber, not a multivitamin in water
Anyone simplifying a stack of single-function powders into one daily shake
Who It’s Not For:
Anyone avoiding dairy, since FitFuel’s immune blend is made from colostrum and contains milk
Anyone wanting a zero-sugar shake, since FitFuel includes a small amount of cane sugar for taste
Anyone on medication who hasn’t checked with their doctor, since it includes immune factors and functional botanicals

What’s Inside

A complete protein base and three functional layers, immune, gut, and detox, in one formula.

Fitties Vegan Protein Blend

21g of pea and rice protein with a 100% amino acid score, a complete plant-based protein that supports lean body composition and forms the base of FitFuel.

Immune Blend

2.5g of immunoglobulins from colostrum, including IgG and lactoferrin, to support immune function and gut health. This is the ingredient that contains milk.

Cell Support (truebroc® Glucoraphanin)

Glucoraphanin from broccoli seed extract, which your body converts to sulforaphane to support its natural detoxification enzymes and antioxidant activity.

Prebiotic Fiber

Inulin, oat fiber, and arabinogalactan from larch, 6g of fiber total, to feed beneficial gut bacteria and support intestinal health.

Aminogen®

A patented, plant-derived enzyme system that supports protein digestion and amino acid absorption, so your body uses more of the protein.

Frequently Asked Questions

What is FitFuel?

FitFuel is a functional daily-nutrition shake. Beyond 21g of complete plant protein, each serving adds immunoglobulins for immune support, prebiotic fiber for gut health, and glucoraphanin for detoxification support, several functions in one formula.

What does FitFuel do?

FitFuel is formulated to support lean body composition, immune function, a healthy immune response, intestinal health, and your body’s natural detoxification, using protein, colostrum immunoglobulins, prebiotic fiber, and broccoli-seed glucoraphanin.

Is FitFuel a meal replacement or a protein shake?

Neither exactly. FitFuel is a functional daily-nutrition shake, more than a plain protein, but at 170 calories it’s a nutritional supplement rather than a full meal replacement. Many people use it once or twice a day alongside meals.

Where does FitFuel’s immune support come from?

A colostrum-derived immune blend that provides 2.5g of immunoglobulins per serving, including IgG and lactoferrin, plus other natural immune factors, to support immune function.

How does FitFuel support detoxification?

FitFuel includes glucoraphanin from broccoli seed, which your body converts to sulforaphane. Sulforaphane supports your natural phase II detoxification enzymes and antioxidant activity.

Does FitFuel contain dairy? Is it vegan?

FitFuel’s protein is plant-based, but its immune blend is made from colostrum, so FitFuel contains milk and is not vegan or dairy-free. If you avoid dairy, this isn’t the right pick.

Does FitFuel have sugar?

Yes. FitFuel includes a small amount of cane sugar (5g added sugar per serving) for taste, along with stevia. It’s not a zero-sugar product, if you want zero added sugar, our protein powders are a better fit.

How do I take FitFuel?

Blend, shake, or stir two scoops into 10 to 14 oz of chilled water, one to two times a day. Adjust the water to your preferred taste and thickness.

Is FitFuel allergen-friendly?

FitFuel is made without gluten, soy, and artificial colors or sweeteners, and it’s non-GMO. It does contain milk, from the immune blend, so it’s not dairy-free or vegan.

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.

How are Fitties products tested?

Every Fitties formula is manufactured 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 manufactured?

Every Fitties formula is manufactured in the USA, at a cGMP-compliant, FDA-registered facility in Orlando, Florida. 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.
