Several treatments can help with nerve damage, ranging from targeted supplements to prescription medications, exercise, and dietary changes. The right approach depends on what’s causing the damage and how far it has progressed. Peripheral nerves can regenerate slowly, roughly one inch per month, so most interventions require weeks or months of consistent use before you notice improvement.
B12: The Deficiency Worth Ruling Out First
Vitamin B12 deficiency is one of the most common and correctable causes of nerve damage. When B12 levels drop too low, the protective coating around your nerves (myelin) gradually breaks down, leading to peripheral neuropathy, loss of balance, numbness, and tingling in the hands and feet. If the deficiency goes untreated long enough, some of that damage becomes permanent, particularly in the spinal cord.
The good news is that high-dose oral B12, at 1 to 2 milligrams daily, works just as well as injections for correcting both the blood and nerve-related symptoms of deficiency. People who’ve had bariatric surgery typically need 1 milligram daily for life, since their bodies can no longer absorb B12 normally from food. If you’re experiencing unexplained tingling, gait problems, or numbness, a simple blood test can tell you whether low B12 is the culprit.
Alpha-Lipoic Acid for Diabetic Neuropathy
Alpha-lipoic acid is one of the most studied supplements for diabetic nerve pain. It’s a powerful antioxidant that appears to protect nerve cells from the oxidative stress caused by high blood sugar. In clinical trials, researchers have used doses of 600 milligrams taken three times daily (1,800 milligrams total) for an initial four-week period, then stepped down to 600 milligrams once daily for ongoing maintenance. Participants who responded to the higher dose saw meaningful reductions in their symptom scores for pain, burning, and numbness.
Alpha-lipoic acid is available over the counter and is generally well tolerated, though it can lower blood sugar, so anyone on diabetes medication should monitor levels carefully when starting it.
Acetyl-L-Carnitine
Acetyl-L-carnitine (ALC) supports nerve cell energy production and has shown real promise for diabetic peripheral neuropathy. In a phase 3 clinical trial published through the American Diabetes Association, patients taking 1,500 milligrams daily for 24 weeks experienced significantly greater improvement in neuropathy symptoms compared to placebo. The treatment group’s clinical neuropathy scores dropped by an average of 6.9 points versus 4.7 points in the placebo group. Notably, the benefits showed up across nearly every symptom category, including numbness, coordination, and sensation, though the specific reduction in pain didn’t quite reach statistical significance.
Prescription Medications for Nerve Pain
When nerve damage causes ongoing pain, two prescription medications are most commonly used: gabapentin and pregabalin. Both work by binding to calcium channels on nerve cells, which reduces the release of excitatory chemical signals responsible for transmitting pain. Think of them as turning down the volume on overactive pain nerves.
Pregabalin binds to those channels more tightly than gabapentin, making it more potent at lower doses. Clinical trials show it’s most effective at higher doses, up to 600 milligrams daily, though doctors typically start lower and increase gradually. Gabapentin doses tend to be higher overall, with the clinical threshold sitting around 1,800 milligrams daily. Both medications can cause drowsiness and dizziness, especially early on, so your doctor will usually ramp up the dose over several weeks to help your body adjust.
These drugs don’t repair nerve damage. They manage the pain that damaged nerves generate. For many people with neuropathy, that pain relief is what makes daily life functional again.
Exercise and Nerve Repair
Aerobic exercise does something for damaged nerves that no pill can fully replicate. After nerve injury, your body ramps up production of signaling proteins called neurotrophins, which play a role in nerve survival and repair but also drive pain sensitization. Regular aerobic activity, such as swimming, walking, or cycling, appears to moderate that neurotrophin surge at the injury site. Animal studies show that treadmill exercise and swimming reduce the buildup of these pain-sensitizing signals in the nerve roots near the spinal cord, which helps explain why people with neuropathy often report less pain after starting an exercise program.
The benefits go beyond pain control. Research from the University of Michigan found that exercise changes the expression of genes involved in inflammation, nerve structure, and metabolism, all of which contribute to nerve health over time. You don’t need intense workouts. Walking 30 minutes most days is enough to start seeing improvements in symptoms over several weeks.
Dietary Changes That Support Nerve Health
What you eat has a measurable effect on nerve function, particularly if metabolic problems like diabetes or obesity are involved. Researchers at the University of Michigan were the first to demonstrate that a ketogenic diet, which is very low in carbohydrates and high in fat, can actually reverse deficits in nerve conduction velocity caused by a high-fat, high-sugar diet. That means the speed at which electrical signals travel through your nerves can improve with dietary intervention alone, independent of exercise.
A long-term ketogenic diet also helped preserve nerve health over time in the same research, suggesting it works both as a treatment and a maintenance strategy. The underlying mechanism involves shifts in genes related to inflammation, nerve structure, and how cells use energy. You don’t necessarily need a strict keto diet to benefit. Reducing processed carbohydrates, managing blood sugar, and eating anti-inflammatory foods like fatty fish, leafy greens, and nuts all move the needle in the right direction.
TENS Units for Symptom Relief
A TENS (transcutaneous electrical nerve stimulation) unit is a small, portable device that sends mild electrical pulses through your skin to interfere with pain signals. For neuropathic pain, the recommended settings are typically 80 to 120 Hz with a pulse width of 50 to 100 microseconds, applied for 15 to 30 minutes per session. You should feel a tingling sensation but no pain.
TENS doesn’t heal nerve damage, but it can provide temporary relief during flare-ups and reduce your reliance on medications. The devices are inexpensive, available without a prescription, and safe for home use. Many people find them most helpful for localized pain in the feet, hands, or lower legs.
What Matters Most for Recovery
The single most important factor in nerve recovery is addressing the underlying cause. If high blood sugar is slowly destroying your nerves, no supplement will outpace that damage. If a B12 deficiency is stripping myelin from your nerve fibers, exercise alone won’t fix it. The treatments above work best in combination and alongside whatever is needed to stop the damage from continuing in the first place.
Peripheral nerves regenerate slowly. Expect weeks to months before noticing meaningful changes with any intervention. Early treatment matters because some nerve damage, particularly in the spinal cord, can become irreversible once enough nerve cells die. The sooner you act, the more function you preserve.
