Abstract
Environmental challenges such as rising atmospheric carbon dioxide concentrations, changes in climate patterns, and heightened frequency and severity of extreme weather events are presenting multifaceted and compounding threats to nutrition and nutrition-related health outcomes. This perspective paper identifies the following 3 critical research gaps at the intersection of dietary supplements and environmental challenges: 1) addressing nutrient deficiencies caused by environmental threats; 2) enhancing biological resilience to environmental stressors; and 3) altering environmental impacts through changes in dietary patterns and industry practices. We discuss methodological challenges and emphasize interdisciplinary collaboration. By addressing these gaps, we can better understand how dietary supplements might contribute to nutrition security and health in the United States amid changing environmental conditions. This knowledge will inform public health policies and interventions, while considering the complex interplay between dietary supplements, nutrition, and environmental factors.
