Neuropathy Explained: Types, Causes, and What You Can Do
If you've ever felt tingling in your fingers, numbness in your toes, or a burning sensation that seems to come out of nowhere — you're not alone. These are some of the most common signs of neuropathy, a condition that affects millions of Americans and becomes increasingly common with age.
The good news? Understanding what's happening inside your body is the first step toward doing something about it. In this article, we'll walk through what neuropathy actually is, the different types, what causes it, and — most importantly — the practical, science-backed steps you can take to support your nerve health starting today.
What Is Neuropathy, Exactly?
At its simplest, neuropathy means damage to the nerves outside of the brain and spinal cord — what doctors call the peripheral nervous system. Think of this system as your body's internal wiring. It carries messages between your brain and every other part of your body: your hands, your feet, your organs, and your muscles.
When those "wires" become damaged, frayed, or inflamed, the signals they carry get disrupted. That's when you might feel tingling, burning, numbness, or sharp pain — most commonly in the hands and feet, though neuropathy can affect almost any part of the body.
Some people describe it like wearing a thick glove when trying to pick up a coin, or like walking on cotton balls. Others say it feels like their feet are on fire at night. However it shows up for you, it's your body telling you that your nerves need attention.
The Four Main Types of Neuropathy
Not all neuropathy is the same. The type you experience depends on which nerves are affected. Here's a clear look at the four main categories:
The most common type. Affects the nerves in your hands and feet, causing tingling, numbness, burning, or sensitivity to touch. Often linked to diabetes, vitamin deficiencies, and aging.
Affects the nerves that control involuntary functions like heart rate, digestion, blood pressure, and bladder control. You may notice digestive trouble, dizziness when standing, or changes in sweating.
Targets the nerves in the hips, thighs, or buttocks — usually on one side of the body. Can cause sudden, severe pain and muscle weakness. Most often seen in people with type 2 diabetes.
Involves damage to a single nerve or nerve group, often in the head, torso, or leg. Can come on suddenly with symptoms like double vision, Bell's palsy, or sharp pain in a specific area.
Of these four, peripheral neuropathy is by far the most widespread — and it's the type most closely connected to the everyday discomfort that brings people searching for answers.

What Causes Neuropathy?
Neuropathy isn't a disease in itself — it's a result of something else happening in the body. Understanding the root causes is essential, because addressing them is often the most effective path to relief. Here are the most common culprits:
| Cause | How It Affects Nerves |
|---|---|
| Diabetes | High blood sugar generates excess free radicals that inflame and damage nerve fibers over time. This is the single most common cause of neuropathy in the United States. |
| Vitamin deficiencies | Low levels of B vitamins (especially B1, B6, and B12) can impair the nerve's protective myelin sheath and slow nerve signaling. |
| Poor circulation | When blood flow to the extremities is reduced — often due to cardiovascular disease or high blood pressure — nerves are deprived of oxygen and nutrients they need. |
| Aging | Natural wear and reduced regenerative capacity make nerves more vulnerable as we get older. Research shows prevalence rises sharply after age 60. |
| Inflammation | Chronic, low-grade inflammation (from autoimmune conditions, obesity, or metabolic syndrome) can directly damage nerve tissue. |
| Medications | Certain drugs — including some chemotherapy agents, statins, and antibiotics — can have neuropathy as a side effect. |
| Alcohol use | Excessive alcohol consumption is toxic to nerve tissue and also depletes B vitamins critical for nerve health. |
| Kidney disease | When kidneys can't properly filter toxins from the blood, those toxins can accumulate and damage peripheral nerves. |
For many people — especially those over 50 — several of these factors overlap. You might be managing diabetes and high blood pressure and dealing with age-related changes all at once. That's why a multi-pronged approach to nerve health is so important.
How to Recognize the Warning Signs
Neuropathy often starts quietly. In the early stages, you might brush off a little tingling or chalk up cold feet to the weather. But catching nerve changes early gives you the best chance of making a real difference. Here are the signals worth paying attention to:
Sensory symptoms are the most recognizable — tingling or "pins and needles" in the hands or feet, numbness that makes it hard to feel temperature or texture, burning or stabbing pain (especially at night), and heightened sensitivity where even a light touch or bedsheet feels painful.
Motor symptoms may include muscle weakness, difficulty with balance or coordination, cramping, and a heavy or clumsy feeling in the legs or feet.
Autonomic symptoms are less obvious but equally important — things like digestive irregularities, dizziness upon standing, changes in sweating patterns, or difficulty regulating body temperature.
If any of these sound familiar, it's worth talking with your healthcare provider. Early identification makes a meaningful difference in how well your nerves respond to support.
Nervala combines 600mg of Alpha Lipoic Acid with Benfotiamine (a highly absorbable form of vitamin B1) in one simple daily capsule. Formulated by Dr. Scott Saunders, M.D., it's designed to target oxidative stress and nourish nerve tissue — two of the most important factors in nerve comfort.

Here's the part that matters most. While you can't undo every factor (we can't stop aging, after all), there's a surprising amount you can do to support your nerves and improve your daily comfort. These strategies aren't just theory — they're backed by research and recommended by healthcare professionals.
Manage Your Blood Sugar
This is the single most impactful thing you can do if you have diabetes or pre-diabetes. High blood sugar multiplies the free radicals that attack nerve cells. Even modest improvements in blood sugar control have been shown to slow the progression of neuropathy. Work with your doctor, monitor regularly, and consider nature-based support like CinnaChroma alongside your current plan.
Nourish Your Nerves with Targeted Nutrients
Two nutrients stand out in the research for nerve health: Alpha Lipoic Acid (ALA), a powerful antioxidant that crosses cell membranes to neutralize free radicals inside nerve cells, and Benfotiamine, a fat-soluble form of vitamin B1 that helps repair nerve linings and protect against oxidative damage. Both are found in Nervala, in clinically-studied forms and doses.
Move Your Body — Gently and Consistently
Regular, low-impact exercise improves circulation to the extremities, delivers oxygen and nutrients to nerve tissue, and helps regulate blood sugar. Walking, swimming, yoga, and light stretching are all excellent options. Even 20–30 minutes most days can make a noticeable difference over time.
Support Heart and Circulatory Health
Healthy nerves depend on healthy blood flow. Supporting cardiovascular wellness — through diet, exercise, and nutrients that promote circulation — helps ensure your peripheral nerves receive the oxygen and nourishment they need. Explore heart health strategies here.
Eat a Nerve-Friendly Diet
Focus on foods rich in B vitamins (eggs, fish, leafy greens, legumes), antioxidants (berries, colorful vegetables, green tea), and healthy fats (salmon, walnuts, olive oil). Reducing processed sugars and refined carbs also helps minimize the blood sugar spikes that contribute to nerve damage.
Stay Consistent and Be Patient
Nerve repair doesn't happen overnight. Your body can and does regenerate nerve cells — but it's a gradual process. The most successful people are those who commit to a daily routine: managing blood sugar, staying active, eating well, and giving their nerves consistent nutritional support. Small steps, taken every day, add up to real results.
Why Alpha Lipoic Acid and Benfotiamine?
You may have heard of these two nutrients before — but understanding why they matter for nerve health is worth a closer look.
Alpha Lipoic Acid (ALA)
ALA is a unique antioxidant because it's both water-soluble and fat-soluble, which means it can work inside and outside of nerve cells. It helps neutralize the free radicals that cause inflammation and damage to nerve tissue. Multiple clinical studies have found that ALA supplementation at 600mg per day can help improve nerve function and reduce uncomfortable symptoms associated with neuropathy — particularly in people with diabetes. It also supports healthy blood sugar metabolism and circulation, both of which are critical for nerve health.
Benfotiamine
Unlike regular vitamin B1 (thiamine), benfotiamine is fat-soluble — meaning it can actually pass through nerve cell membranes to deliver support directly where it's needed. Research shows it helps protect the delicate lining of nerve tissue, supports the tiny blood vessels (microcirculation) that nourish your nerves, and helps block the formation of harmful compounds called AGEs (advanced glycation end-products) that result from high blood sugar.
Together, ALA and benfotiamine address two of the biggest threats to nerve health — oxidative stress and inflammation — from complementary angles. That's exactly why Dr. Scott Saunders, M.D. chose to combine them in Nervala.
The Connection Between Neuropathy, Blood Sugar, and Heart Health
One thing many people don't realize is how closely connected these three areas of health really are. Neuropathy, blood sugar imbalances, and cardiovascular problems often go hand in hand — and addressing one can positively impact the others.
High blood sugar damages blood vessels and nerves simultaneously. Poor circulation from heart or blood pressure issues starves nerves of nutrients. And the inflammation that fuels all three conditions creates a cycle that feeds itself if left unaddressed.
This is why a comprehensive approach — one that supports nerve health, blood sugar balance, and cardiovascular wellness together — tends to produce the best results. It's also why many Barton Supplements customers find success in building what we call a "health stack" — pairing targeted supplements that work together. You can learn more about this interconnection in our articles on how to lower blood sugar naturally and Heart Health 101.
