Palmitoylethanolamide (PEA) is a naturally occurring fatty acid amide that has been studied for its anti-inflammatory and neuroprotective properties. Its use in supporting or treating Multiple Sclerosis (MS) is primarily based on scientific rationale and preliminary evidence rather than longstanding tradition. Preclinical studies suggest that PEA can modulate mast cell activity, reduce neuroinflammation, and may help protect nerve cells from damage, which are relevant mechanisms in MS pathology. A small number of clinical studies and case reports have examined PEA’s effects in MS patients. For example, a pilot open-label study (Cocito et al., 2014) found that PEA, as an add-on therapy, was associated with improvement in pain and spasticity in MS patients, with a good safety profile. However, these studies generally involve small sample sizes, lack rigorous controls, and are preliminary in nature.

Overall, while there is a plausible scientific mechanism and some early clinical data to suggest PEA could be beneficial for symptoms like pain and spasticity in MS, there is insufficient high-quality evidence from large, randomized controlled trials to strongly support its routine use for this condition. Therefore, the evidence is modest and further research is needed to confirm efficacy and safety in MS patients.
