Nutraceutical supplements encompass a broad category of products derived from food sources that may provide health benefits beyond basic nutrition.
Nutraceutical supplements represent a growing area of interest in neurodegenerative disease research and clinical practice. These compounds, which include vitamins, minerals, herbal extracts, and other dietary supplements, are pursued for their potential neuroprotective properties, antioxidant effects, and ability to support mitochondrial function.
This page provides comprehensive information on the most commonly used nutraceutical supplements for Alzheimer's disease, Parkinson's disease, and other neurodegenerative conditions. Topics covered include mechanisms of action, clinical evidence, safety considerations, and recommendations for use.
