Melatonin and Heart Failure: What the New Research Really Shows

Scientific visualisation of cardiac tissue and glowing biochemical pathways representing melatonin and cardiovascular health.

Sensational headlines claiming that everyday sleep supplements increase the risk of heart failure have triggered widespread alarm among health-conscious consumers. However, a rigorous examination of the underlying epidemiological data reveals a classic distinction between correlation, confounding variables, and genuine pharmacological…

Melatonin’s Influence on Blood Cholesterol Levels

Scientific visualisation of the human brain, neurons and biochemical signalling representing melatonin and metabolic regulation.

Melatonin is widely recognised for its role in regulating sleep and circadian rhythm. However, growing research suggests its physiological influence extends beyond sleep – including potential effects on lipid metabolism, oxidative stress, and cardiometabolic health. Recent clinical investigations have examined…

Melatonin and DNA Repair: New Scientific Insights

Glowing DNA double helix undergoing cellular repair, representing melatonin’s role in nighttime DNA protection.

Melatonin is widely recognised for its role in regulating sleep, but emerging human research suggests its biological influence may extend further, potentially supporting the body’s natural ability to repair oxidative DNA damage during sleep. Recent findings from a randomised, placebo-controlled…
