Combination Supplement Therapy: A New Frontier in Treatment of Neurodegenerative Diseases

This review highlights the importance and potential beneficial effects of dietary supplements, including taurine, tauroursodeoxycholic acid (TUDCA), curcumin, coenzyme Q10, creatine, and N-acetylcysteine, in the management of neurodegenerative diseases. Studies in preclinical models have consistently shown significant potential of these supplements in mitigating neurodegenerative pathology. Through a range of mechanisms targeting different molecular pathways, these supplements demonstrate therapeutic outcomes in preclinical models of conditions such as Parkinson disease, Alzheimer disease, amyotrophic lateral sclerosis, and Huntington disease. This review discusses published data on each of these supplements in the context of neurodegenerative diseases. It also discusses a combination therapy concept and proposes a strategy to formulate an optimal blend of these supplements. This combination approach will target key processes, including mitochondrial dysfunction, protein misfolding, neuroinflammation, and oxidative stress responsible for neurodegenerative conditions. Additionally, this review examines various models used for both the initial screening and subsequent assessment of candidate supplement combinations.
