The Claim

Lower circulating melatonin levels are associated with an increased risk of cardiovascular disease, metabolic syndrome, and sleep disorders, and the restoration of physiological melatonin rhythms may mitigate disease progression, potentially mediated by age-related pineal calcification, circadian disruption, and chronic inflammation.

In plain English

People with heart disease, metabolic issues, or sleep problems often have lower levels of melatonin, the body's natural sleep hormone. This drop might be caused by aging, poor sleep cycles, or long-term inflammation, and boosting melatonin back to normal levels could potentially help slow down these health conditions.

See the scientific wording

Reduced circulating melatonin levels are consistently observed in patients with cardiovascular diseases, metabolic syndrome, and sleep disorders, indicating a strong association between melatonin deficiency and increased cardiovascular risk. This decline is linked to age-related pineal calcification, circadian disruption, and chronic low-grade inflammation, suggesting that restoring physiological melatonin rhythms may mitigate disease progression.

What the research says

1 study

  1. Study: Chronobiotic and cytoprotective activity of melatonin in the cardiovascular system. Doses matter

    The review synthesizes epidemiological and clinical data showing consistently lower endogenous melatonin in CVD and metabolic disease populations. The authors frame this deficiency as a contributing factor to inflammaging and circadian misalignment, supporting the rationale for exogenous supplementation.
