Vitamins in the Prevention and Support Therapy of Neurodegenerative Diseases

This review examines the role of vitamins in preventing and managing neurodegenerative diseases like Alzheimer’s, Parkinson’s, ALS, and multiple sclerosis. It highlights the neuroprotective properties of vitamins B, D, E, C, K, and A, which may reduce oxidative stress, inflammation, and cognitive decline. The study draws on existing research but does not include new clinical trials. While some findings support vitamin supplementation for brain health, generalizability remains uncertain due to varying individual metabolism and dietary patterns. The review also discusses EU food law regulations on health claims related to vitamins, emphasizing the need for clearer consumer guidance. The authors call for further research to substantiate these potential benefits.

A balanced diet rich in vitamins B, C, D, E, K, and A may support brain health, though evidence remains mixed. Prioritizing whole foods like leafy greens, fish, nuts, and dairy can provide these nutrients naturally. Regular exercise, quality sleep, and cognitive engagement (e.g., learning new skills) are additional evidence-backed strategies to maintain cognitive function. Since vitamin metabolism varies, supplementation should be considered cautiously and tailored to individual needs under medical guidance.
