How Do Epidemiologists Study the Impact of Supplements?
Epidemiologists use various research methods to study the effects of nutritional supplements, including:
Observational studies: These studies look at the health outcomes of people who take supplements versus those who do not. Randomized controlled trials (RCTs): Participants are randomly assigned to receive either the supplement or a placebo, allowing for a clear comparison of effects. Meta-analyses and systematic reviews: These methods combine data from multiple studies to provide a more comprehensive understanding of supplement effectiveness.
