FitFuel is at the forefront of biotransformation, offering a unique solution for individuals facing ongoing health challenges. This entirely natural, fructose-free blend is formulated with components that enhance gastrointestinal wellness while supporting the body's detoxification processes and maintaining cytokine equilibrium. FitFuel features a range of patented and exclusive ingredients, including 21 g of Fitties Vegan Protein, a non-GMO, plant-based protein. Additionally, it contains IgG 2000 CWP™, OncoPLEX™ (glucoraphanin), and arabinogalactan, a prebiotic known for its health benefits. Health professionals have observed optimal results when FitFuel is integrated with a modified elimination diet.*


Fitties Vegan Protein, a unique formulation by Fitties, combines pea protein isolate, glycine, taurine, rice protein concentrate, and L-glutamine. This blend offers 21 g of plant-based protein in each serving of FitFuel. Renowned for its ease of digestion, being gluten-free, and attaining a perfect amino acid score of 100%, Fitties Vegan Protein is ideal for supporting protein metabolism and enhancing lean muscle mass. The addition of Aminogen® boosts the digestibility and absorption of the protein.*

FitFuel includes IgG 2000 CWP™, a concentrated immunoglobulin extract from colostral whey peptides. It guarantees a minimum of 40% IgG immunoglobulin, along with a variety of beneficial compounds like growth factors, sialic acid, lactoferrin, proline-rich peptides (PRPs), oligosaccharides, and gangliosides. These components collectively offer multiple health advantages, including essential immune support and modulation, maintaining lean body mass, and promoting the health of the brain, thymus, gut flora, and cytokine equilibrium.*[3]

Ingesting immunoglobulins from colostrum is a proven method for bolstering passive immunity, safeguarding the body, and eliminating undesirable substances.[4-7] IgG, the most adaptable immunoglobulin, performs all immunoglobulin functions, which explains the wide-ranging immune-supportive capabilities of IgG 2000 CWP.[8] Studies show that bovine colostrum supplements offer additional benefits like preserving gastrointestinal health.[9-11] In the realm of sports nutrition, oral immunoglobulins have been employed to support lean muscle mass,[12] enhance physical performance, and aid recovery after intense training sessions.[9,13] Each serving of FitFuel contributes 2.5 grams of immunoglobulins, aiding in meeting individual dosage needs.*

OncoPLEX™ (glucoraphanin), another patented ingredient derived from plant sources, specifically broccoli seeds, is also included.[14] Research has extensively shown that when glucoraphanin converts to its active form, sulforaphane, it efficiently activates the body's natural phase II detoxification enzymes.[15-17] This process is crucial for bolstering antioxidant activity and safeguarding cells, cell membranes, and tissues against oxidative stress.*

Arabinogalactan, derived from the larch tree, is a non-digestible, soluble dietary fiber comprising arabinose and galactose monosaccharides. As a top-tier fiber source, it positively influences gut microflora by acting as a prebiotic and is a precursor to short-chain fatty acids, all of which are vital for gastrointestinal well-being.*[18,19]
