Are Nerve Support Supplements Effective? An MD's Evidence Review
Not all nerve support supplements are created equal — and the dose on the label matters more than the ingredient name. In this evidence review, fellowship-trained peripheral nerve surgeon Dr. Michael Fitzmaurice breaks down the clinical research behind seven common neuropathy supplement ingredients — including which have Level B RCT evidence, which are overhyped, and one ingredient with a serious safety flag for chemotherapy patients that almost no supplement brand discloses.

Vitamins That Support Nerve Repair: What the Science Says
This post answers the high-volume PAA cluster "what vitamins repair nerve damage" with physician-level mechanistic depth instead of generic listicle content. Dr. Fitz walks through the five most evidence-supported nutritional agents — benfotiamine (B1), pyridoxine (B6), methylcobalamin (B12), alpha-lipoic acid, and acetyl-L-carnitine — explaining the distinct biological pathway each one addresses. The post establishes why a multi-pathway approach is scientifically necessary (not just commercially convenient), clarifies active vs. inactive forms for each nutrient, and ends with a tiered action plan and product integration. The NeuroAxis mention is woven in organically... Read more...
Nerve Tingling and Burning: Why Your Nervous System Is Caught Between Damage and Repair
If your nerves feel on fire one moment and completely numb the next, there's a precise biological reason — and it's not random. This post explains why your nervous system gets caught between damage and repair, the everyday stressors keeping it stuck, and the specific nutrients and habits that help your body pull toward healing.

Can You Reverse Neuropathy? What the Science Actually Says
DR. FITZ NUTRITION — NERVE HEALTH & METABOLIC SCIENCE NERVE HEALTH · NERVE REGENERATION If you've been told that neuropathy is a one-way door — that once your nerves are damaged, the best you can do is manage the pain — this post gives you a more complete answer: the biology of nerve regeneration, what "reversal" actually means at the cellular level, and what the science says you can realistically do about it. Michael Fitzmaurice, M.D. Peripheral Nerve Surgeon & Metabolic Health Educator "Peripheral nerves can regenerate. That is established... Read more...
What Causes Neuropathy in the Feet?
Neuropathy in the feet often begins with tingling, burning, numbness, or electric-shock sensations in the toes. This article explains why nerve symptoms usually start in the feet, the most common underlying causes—from metabolic and nutritional issues to toxins and autoimmune conditions—and what may be reversible when addressed early. Learn how clinicians evaluate foot neuropathy and where lifestyle, medical treatment, and nerve-support strategies fit. Read more...
Why Nerve Symptoms Feel Worse at Night
Dr. Fitz Nutrition — Nerve Health & Metabolic Science Nerve Health · Neuropathy Symptoms Why Do Nerve Symptoms Feel Worse at Night? A Peripheral Nerve Surgeon Explains If your feet start burning the moment you lie down, you're not imagining it — and it's not a sign that your nerves are suddenly getting worse. There's a very specific biological reason this happens, and understanding it puts you back in control. MF Michael Fitzmaurice, M.D. Peripheral Nerve Surgeon & Metabolic Health Educator Nighttime doesn't damage your nerves — but it does... Read more...
Why Your Nerves Need Multi-Pathway Nutrition
Peripheral nerves depend on multiple interconnected systems, including cellular energy, myelin integrity, circulation, antioxidant balance, and inflammation regulation. Research suggests that supporting these pathways together—rather than focusing on a single nutrient—better reflects how nerves function. This article explains why multi-pathway nutrition matters and how bioavailable ingredient forms, such as benfotiamine and methylcobalamin, can influence how effectively nutrients are utilized by nerve tissue. Read more...
Neuropathy Without Diabetes: 7 Common Causes
Neuropathy is often linked to diabetes—but many people experience nerve symptoms without ever having high blood sugar. This article explores seven common non-diabetic causes of neuropathy, including nutrient deficiencies, medication effects, autoimmune conditions, infections, and small fiber nerve disorders. You’ll learn why symptoms occur, what often gets missed in routine evaluations, and how nutrition and lifestyle choices can support overall nerve health alongside proper medical care. Read more...
Vitamin B for Nerve Pain: What the Science Says About Benfotiamine, Methylcobalamin, and a Systems-Based Approach
Clinical research suggests that benfotiamine (vitamin B1) and methylcobalamin (vitamin B12) may help support nerve function and reduce neuropathic symptoms, particularly in diabetes-related nerve stress, when used in bioactive forms and appropriate combinations. Read more...
What to Look for in a Nerve Support Supplement
Nerve support supplements vary widely in quality, purpose, and design—and many rely on marketing claims rather than sound biological reasoning. Because nerve health depends on multiple overlapping systems, meaningful support is rarely achieved through a single ingredient or mechanism alone. Evaluating a supplement requires looking beyond the label to understand dosing, formulation logic, safety, and how ingredients work together over time. This article outlines a practical, evidence-informed framework for assessing nerve support supplements with clarity and confidence. By focusing on formulation principles instead of hype, readers can make more informed... Read more...
Daily Habits That Support Nerve Health: How Metabolism, Movement, and Recovery Shape Nerve Function
Peripheral nerve health is shaped by everyday habits that influence metabolism, energy production, and signal transmission. This article explains how blood sugar stability, nutrition, regular movement, strength training, sleep, and stress management work together to support nerve function over time. By focusing on consistent, metabolically supportive routines, it’s possible to create an internal environment that helps nerves function more efficiently and remain resilient. Read more...
Nerve Health Basics: How Metabolic Health and Blood Sugar Affect Peripheral Nerves
Peripheral nerve health depends on steady energy production, accurate signal transmission, and strong structural support. This article explains how metabolic health—especially blood sugar stability and insulin sensitivity—shapes nerve function over time. Learn how nutrition, lifestyle habits, and metabolic resilience influence the biological environment nerves rely on to function and repair themselves. Read more...
B Vitamins for Neuropathy: The Truth About B1, B6, and B12
B vitamins have the strongest evidence base of any nutrients studied for peripheral nerve health — but only when you're taking the right forms at the right doses. This post breaks down exactly what B1 (benfotiamine), B6, and B12 (methylcobalamin) do for your nerves, why the form on your supplement label matters more than most people realize, and what a quality nerve formula actually looks like. Written by Dr. Michael Fitzmaurice, M.D., fellowship-trained peripheral nerve surgeon. Read more...
