Sesamin is a lignan compound found primarily in sesame seeds and sesame oil. There is emerging scientific interest in sesamin for cardiovascular health, mostly from preclinical and a limited number of clinical studies. Research suggests that sesamin may exert beneficial effects on the heart and vascular system through several mechanisms:

• Lipid Regulation: Animal studies have shown that sesamin can lower total cholesterol, LDL cholesterol, and triglyceride levels, possibly by modulating enzymes involved in lipid metabolism.
• Antioxidant Activity: Sesamin possesses antioxidant properties that may protect against oxidative stress, a key contributor to atherosclerosis and cardiovascular disease.
• Anti-inflammatory Effects: Some research indicates sesamin may help reduce inflammation, another risk factor for cardiovascular disease.

However, the majority of the evidence comes from laboratory and animal studies. Human trials are limited, and those available are often small or of short duration. A few clinical studies have suggested modest improvements in lipid profiles with sesamin supplementation, but more robust data are needed to confirm these effects and clarify the optimal dose and safety profile.

In summary, while there is some scientific rationale for sesamin’s use in supporting heart health, the current evidence is preliminary and does not yet fully validate its effectiveness for this purpose in humans.
