Dietary supplements and Parkinson’s disease: separating hope from hype. A dietary supplement is a product such as a vitamin, probiotic or nutrient taken to add to the diet and potentially support health. Prasad and colleagues describe in a new paper in the Journal of Parkinson’s Disease the current state of the science on dietary supplements and whether they may influence Parkinson’s disease progression. Key points: - Biotics including probiotics, prebiotics and synbiotics showed promising effects on inflammation, oxidative stress and the gut microbiome in several studies. - Nicotinamide riboside, a form of vitamin B3, emerged as a promising candidate in early trials targeting mitochondrial function and cellular energy. - Omega-3 fatty acids combined w/ vitamin E demonstrated reductions in inflammatory and oxidative stress biomarkers, however clinical results were mixed. My take: This review is important because many folks living w/ Parkinson’s disease are already taking supplements, frequently w/o clear guidance from evidence. The future may not be about one magic supplement, however about targeting multiple pathways including inflammation, mitochondrial health and the gut microbiome at the same time. We need larger and longer studies before we can confidently recommend most supplements as disease-modifying therapies. Here are 5 points that resonated w/ me: 1- Parkinson’s disease is more than dopamine loss and may involve inflammation, oxidative stress and gut microbiome changes. 2- The gut-brain connection continues to emerge as one of the most exciting frontiers in Parkinson’s research. 3- Supplements such as probiotics and omega-3 fatty acids appear relatively safe, however safety does not always mean effectiveness. 4- Nicotinamide riboside is gaining attention because it may support how cells generate and use energy. 5- The future of Parkinson’s care may combine exercise, nutrition, sleep and personalized therapies into a more holistic treatment plan. https://journals.sagepub.com/doi/full/10.1177/1877718X261446386 #parkinson #vitamin #supplements #diet #nutrition
