Cardiovascular disease, type 2 diabetes mellitus and associated diseases combined are the leading health burden and cause of mortality worldwide; therefore, the necessity for an intervention is paramount. Dietary interventions to improve cardiometabolic health are highly sought after as they possess less risk than pharmacological drugs. It has been postulated that Quercetin may be beneficial in improving cardiometabolic outcomes. However, to date, no research has explored this using a placebo randomized intervention.
