Questions? We've Got Answers.
Is this safe to take with my medications?
FUEL uses food-based ingredients with GRAS safety status. However, if you're on prescription medications (especially antibiotics or immune suppressants), consult your doctor before starting any new supplement. We provide your doctor with ingredient lists and clinical study documentation.
What if it doesn't work for me?
90-Day Money-Back Guarantee. Use FUEL for 90 days. If you don't feel a dramatic improvement in your gut health, email us and we'll refund every penny. You keep all products and bonuses. No questions asked. No hassle.
How long do I need to take FUEL?
FUEL works best with consistent daily use. Your gut needs ongoing support to maintain the rebuilt barrier and keep bacteria properly fed. Most people notice that stopping supplementation gradually returns symptoms as the gut environment shifts back. Think of it like this: You wouldn't stop brushing your teeth once they're clean. FUEL maintains your gut's foundation.
Why do I need 5 different fiber types?
Your gut bacteria are diverse—they need diverse food. Each fiber type feeds different bacterial species: Tapioca fiber provides slow fermentation and is gentle. Acacia gum feeds bifidobacteria. FOS enables rapid butyrate production. Green banana provides resistant starch for the colon. L-arabinose offers prebiotic and glycemic support. One fiber feeds one group of bacteria. Five fibers provide complete microbiome nourishment.
Will this help with weight management?
Indirectly, yes. When your gut bacteria are properly fed, they stop sending "feed me processed carbs" signals, cravings for junk food disappear, metabolism optimizes, energy increases (you move more naturally), and bloating reduces (you look and feel lighter). FUEL isn't a weight loss product—it's a gut health system. But healthy guts support healthy weight naturally.
Can I take this if I have IBS, Crohn's, or other gut conditions?
Many of our users have these conditions and see improvement. However, if you have a diagnosed GI condition, consult your gastroenterologist before starting FUEL. We're happy to provide clinical studies and ingredient documentation for your doctor. FUEL supports gut health—it's not a replacement for medical treatment.
