Clinical Trial Summary

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. Previous non-randomized interventions have shown that oral peppermint may be beneficial in improving cardiometabolic outcomes. However, to date, no research has explored this using a placebo randomized intervention. Therefore, the primary purpose of the proposed investigation is to test the ability of oral peppermint oil supplementation to improve cardiometabolic parameters in healthy individuals.
