FAQ
Dr. Fitzmaurice is a surgeon specializing in peripheral nerve and metabolic health with clinical expertise in evidence-based supplementation. Dr. Fitz Nutrition formulas are developed using peer-reviewed research on nutrients that support healthy nerve function, metabolic balance, and longevity in adults 40+. Our mission is to provide physician-led, third-party tested supplements that complement a healthy lifestyle—not to replace medical care. Every formula prioritizes quality, transparency, and science over marketing hype.
Most supplement brands use generic formulas and marketing claims. Dr. Fitz Nutrition is different because: (1) formulas are designed by a nerve and metabolic health clinician, (2) every ingredient has a research-backed reason and dose, (3) we third-party test for purity and potency, (4) we’re transparent about what our supplements can and cannot do, and (5) we focus on long-term metabolic and nerve health, not quick fixes. We educate rather than overpromise.
Yes—when the right nutrients are used at research-backed doses. Specific vitamins (B vitamins including methylcobalamin B12, benfotiamine B1, and B6), antioxidants (alpha-lipoic acid, N-acetylcysteine), amino acids (acetyl-L-carnitine), enzymes (serrapeptase, bromelain), and cofactors (CoQ10, curcumin with BioPerine®) have clinical evidence supporting healthy nerve cell function, energy production, and metabolic balance. However, supplements work best alongside diet, exercise, sleep, and stress management. They complement lifestyle—they don’t replace it. Dr. Fitz Nutrition formulas combine these proven nutrients in doses shown in studies to deliver measurable benefits.
Results vary by individual and depend on your baseline health, diet, sleep, activity, and which product you’re using. Some people notice improved energy or comfort within 1-2 weeks. Others need 6-12 weeks to see meaningful changes. We recommend committing to at least 2–3 months before evaluating whether a product is right for you, as nutrient absorption and cellular changes take time. Keep a simple log of energy, comfort, and mood to track subtle improvements you might otherwise miss.
Dr. Fitz supplements are formulated for adults concerned with nerve and metabolic health, but individual safety depends on your specific medical history and medications. Always consult your primary care doctor or specialist before starting any new supplement, especially if you have a diagnosed condition or take prescription medications. Some nutrients can interact with medications or may not be appropriate for certain conditions. Your healthcare provider can review the ingredient list and dose to determine if a product is safe for you. We’re happy to provide detailed ingredient information and clinical references to share with your doctor.
