MELATONIN, AN ANTI-AGING PRODUCT ?<\/h1>\n

Melatonin, longevity and anti-ageing effects<\/h2>\n

Melatonin is a hormone produced by the pineal gland. Known for regulating sleep, its effects extend far beyond this primary role. With antioxidant, immunomodulatory and neuroprotective properties, it appears essential to understanding ageing and longevity. Its gradually declining secretion with age is accompanied by sleep disorders, metabolic imbalances and reduced vitality. Studying melatonin from an anti-ageing perspective helps explain how this molecule contributes to maintaining overall health.<\/p>\n

The biology of melatonin<\/h2>\n

Melatonin is synthesised from tryptophan via serotonin, then released mainly at night. Its production is controlled by the light-dark cycle perceived by the retina. Darkness stimulates secretion, while light suppresses it.
Its role as a biological messenger makes it a central regulator of circadian rhythms. It affects sleep and many hormonal, metabolic and cellular processes.<\/p>\n

Signs of melatonin deficiency<\/h2>\n

Melatonin production gradually decreases with age, but certain signs suggest significant deficiency: difficulty falling asleep despite fatigue, frequent night-time awakenings and fragmented sleep, reduced total sleep duration, reduced alertness and daytime drowsiness, mood changes (irritability, anxiety or depressive tendencies), loss of concentration and memory problems, weakened immunity with more frequent infections, and visibly accelerated skin ageing.
These symptoms are non-specific and should be assessed by a doctor, who may recommend testing or appropriate supplementation.<\/p>\n

Melatonin and sleep<\/h2>\n

Melatonin directly contributes to falling asleep. It lowers body temperature and signals to the brain that night has arrived. It improves sleep quality and reduces the time taken to fall asleep.
Chez les personnes \u00e2g\u00e9es, la diminution de la production de m\u00e9latonine est responsable d’un sommeil plus l\u00e9ger, fragment\u00e9 et peu r\u00e9parateur. Or un sommeil profond est essentiel pour la r\u00e9paration cellulaire, l\u2019\u00e9quilibre hormonal et la consolidation de la m\u00e9moire.<\/p>\n

Antioxidant and anti-inflammatory properties<\/h2>\n

Melatonin is one of the most powerful natural antioxidants. It neutralises free radicals and stimulates protective enzyme production. It therefore protects DNA, proteins and cell membranes against oxidative stress, a major factor in ageing.
It also acts on chronic inflammation, a characteristic of pathological ageing. By regulating inflammatory cytokine production, it limits inflammaging, a process responsible for many age-related diseases.<\/p>\n

The functions of melatonin<\/h2>\n

Melatonin has multiple functions.<\/p>\n
