A new systematic review of observational and interventional studies examines the use of antioxidants in patients with COVID-19. Published in the Food Science & Nutrition journal, the results demonstrate highly beneficial roles for this class of micronutrients in reducing inflammation, ventilation requirement, hospitalization, intensive care unit admission, mortality, and other aspects of coronavirus care. Confirming that intravenous supplementation with vitamin C significantly decreases mortality from COVID-19 in severe cases, and that studies show vitamin D, selenium, and zinc similarly play positive roles in fighting the disease, the researchers conclude that antioxidants can improve clinical outcomes.
A new meta-analysis published in the Frontiers in Aging Neuroscience journal examines the relationship between Alzheimer’s disease and plasma levels of vitamin C. Authored by researchers from the United States and Pakistan, the paper finds that deficiency of vitamin C is involved in the progression of the disease. Crucially, therefore, the researchers conclude that vitamin C supplementation is a plausible strategy for its prevention and treatment.
