Taking melatonin supplements can help lower high blood pressure, especially at night, by improving blood vessel function and balancing the body's natural sleep-wake rhythms. This is particularly helpful for people who don't normally see their blood pressure drop at night or those with metabolic syndrome, potentially protecting their heart and blood vessels over the long term.

Taking melatonin supplements might help lower high blood pressure at night and improve overall blood pressure readings in people with heart conditions. This effect seems to happen because melatonin could help relax blood vessels and calm the nervous system.

Taking melatonin supplements may lower your blood pressure, blood sugar, and bad cholesterol, while also reducing inflammation and boosting your body's natural antioxidants.

Taking melatonin supplements might slightly lower your top blood pressure number by about 2 points. However, how much it actually helps depends on your starting blood pressure and other personal health factors, so the real-world benefit isn't the same for everyone.

Melatonin, a hormone your body naturally produces, acts like a protective shield that reduces cellular damage in your blood vessels. By calming this internal stress, it helps keep your heart and blood vessels healthy and may lower the risk of heart-related problems.
