Rating (out of 5): 2

L-taurine is an amino sulfonic acid that plays multiple physiological roles, particularly in the central nervous system. There is emerging scientific interest regarding its potential to support or treat nerve damage (neuropathy), though clinical evidence remains limited. Preclinical studies in animal models have shown that taurine supplementation can exert neuroprotective effects. These include reducing oxidative stress, modulating calcium homeostasis, and inhibiting excitotoxicity—factors implicated in nerve injury and degeneration. For example, taurine has been observed to reduce neuronal apoptosis and support nerve regeneration in studies involving peripheral nerve injury in rats. Additionally, taurine’s anti-inflammatory and antioxidative properties may help mitigate the secondary damage that follows nerve injury.

However, human clinical trials specifically evaluating taurine for nerve damage are sparse. Most of the evidence is derived from in vitro and animal studies, with only a few small-scale human studies suggesting possible benefits in diabetic neuropathy or chemotherapy-induced neuropathy. No large, well-controlled clinical trials have established taurine as a standard treatment for nerve damage. Therefore, while the scientific rationale and preliminary data are promising, the overall strength of evidence remains low (rated 2/5). More robust human research is needed to confirm efficacy and establish appropriate dosing.
