Alpha-Lipoic Acid and Nerve Recovery in Carpal Tunnel Syndrome

Updated: February 2026

Carpal Tunnel Syndrome (CTS) is traditionally managed through mechanical means—splints, ergonomic adjustments, or surgery. However, recent clinical research suggests that nutritional intervention, specifically with Alpha-Lipoic Acid (ALA), may provide a biological path to recovery by addressing the underlying nerve damage.

The Clinical Trial: 600mg of ALA Daily

In this double-blind, randomized clinical trial, researchers evaluated the impact of 600mg of Alpha-Lipoic Acid on patients suffering from CTS. Unlike many supplements that merely mask symptoms, ALA was tested for its ability to improve neurophysiologic recovery—the physical health and signaling speed of the median nerve.

Key Findings and Nerve Conduction

The results revealed a significant divergence between the ALA group and the placebo group:

• Symptom Relief: Participants reported a marked decrease in the classic "pins and needles" sensation (paresthesia) and nocturnal pain.
• Electromyography (EMG) Gains: The study utilized EMG to measure nerve conduction velocity. The ALA group showed objective improvement in how quickly electrical impulses traveled across the wrist, suggesting actual repair of the nerve fiber.
• Oxidative Stress Reduction: As a "universal antioxidant," ALA neutralizes free radicals in both water- and fat-soluble environments, protecting the delicate tissues surrounding our nerves.

The "Universal" Antioxidant Mechanism

Alpha-Lipoic Acid is unique because it can regenerate other essential antioxidants like Vitamin C and Vitamin E. In the context of aging and repetitive movement, this creates a protective "shield" against the inflammation that typically narrows the carpal tunnel and impacts the median nerve.
