Melatonin, the hormone that helps regulate sleep, is also being studied for its ability to protect blood vessels and reduce cellular damage. Scientists believe it could help prevent and treat heart-related conditions like high blood pressure, hardened arteries, and heart damage from interrupted blood flow.

Our current analysis shows that the evidence we have reviewed leans toward melatonin offering potential benefits for heart health. We looked at one assertion regarding whether this sleep hormone can help prevent or treat conditions like high blood pressure and hardened arteries [1]. What we found so far points to melatonin doing more than just helping you sleep. The research we examined suggests it may protect blood vessels and lower cellular damage, which is harm to your body cells. Our analysis of the available research shows that the evidence leans toward melatonin supporting heart-related health. We found 1 studies support, 0 studies refute this connection. The evidence we've reviewed leans toward melatonin playing a role in managing blood pressure and reducing artery stiffness. We also noted that it might help limit tissue damage when blood flow is temporarily blocked. Based on what we've reviewed so far, these effects are still being mapped out. We do not have a complete picture yet, and our current analysis is based on a limited set of findings. As more data becomes available, our understanding will likely grow. We are tracking this area closely to see how these early signals hold up over time. If you are considering melatonin for heart health, talk to your doctor first. It is best used as a general sleep aid right now, and you should not replace prescribed heart medications with it. Keeping your blood pressure in check still relies on proven habits like eating whole foods, moving regularly, and following medical advice.
