Melatonin And Blood Pressure

Melatonin may modestly lower blood pressure, but research findings are mixed. Some studies show a small benefit, especially in people with high blood pressure, while others find no effect. Melatonin's main benefit comes from promoting better sleep, which may indirectly support heart health.

Melatonin may interfere with blood pressure medications, such as beta-blockers or ACE inhibitors, potentially leading to either increased or decreased blood pressure levels.

Melatonin is widely known as the hormone that regulates sleep, but its effects extend beyond the sleep-wake cycle. Emerging research suggests it plays a role in cardiovascular health, particularly in blood pressure regulation.

For most people, melatonin does not raise blood pressure. In fact, clinical trials consistently show the opposite: melatonin supplementation modestly lowers both systolic and diastolic blood pressure. However, there is one important exception.

Melatonin is a natural hormone that regulates sleep and may also help lower blood pressure in people with hypertension. Learn how melatonin works, what the research says, and how to use it safely and effectively.

In healthy postmenopausal women, supplementation with 10 mg melatonin was well-tolerated, but we did not observe any significant improvements in pulse wave velocity, blood pressure or quality of sleep compared with placebo.
