Introduction: Modern lifestyles characterized by unhealthy diets and physical inactivity increase the risk of coronary heart disease. Atherosclerosis, the primary underlying cause, can be mitigated through non-pharmacological interventions. Although coriander and young coconut water have been shown to reduce cholesterol levels, their comparative effects on triglyceride levels remain unclear. Aims: This study aims to evaluate and compare the effectiveness of boiled coriander seed water and young coconut water in reducing triglyceride levels. Method: This study employed a quantitative quasi-experimental pretest–posttest control group design. The population comprised 484 educators and educational staff at Nusa Cendana University, with 48 participants selected through purposive sampling based on inclusion and exclusion criteria. Data analysis included paired t-tests to compare pretest and posttest values within groups, followed by one-way ANOVA and Tukey HSD tests to compare posttest outcomes between groups. Results: In this study, the coriander seeds boiled water group showed a significant reduction in triglyceride levels from 139.5 mg/dL to 120.8 mg/dL (p=0.037) after 1 week of intervention. In contrast, the young coconut water group showed an insignificant decrease from 98 to 90 (p=0.386). The control group, without intervention, did not experience significant changes (p=0.75). These results show the potential of coriander seeds as a triglyceride lowering agent, while young coconut water shows more variable results. Conclusion: Boiled coriander seed water is more effective in reducing triglyceride levels than young coconut water.
