Functions and Effects
Regulates sleep
Melatonin can shorten the time spent awake before falling asleep and reduce the time it takes to fall asleep, thereby improving sleep quality.
Exogenous melatonin supplementation helps maintain internal melatonin levels at a "youthful" state; this not only deepens sleep and enhances sleep quality but also improves overall physiological function, boosts quality of life, and slows the aging process.
Regulates immune function
Melatonin stimulates lymphocytes to synthesize and release cytokines, increases the count of lymphocytes and eosinophils, and boosts immunity.
Anti-aging effects
Melatonin is a natural hormone in the human body with significant antioxidant properties. It exerts anti-aging effects by scavenging free radicals, providing antioxidant protection, and inhibiting lipid peroxidation, thereby protecting cellular structures.
Application
Health Food and Nutritional Supplements Sector
Sleep-enhancing health foods: As an ingredient, melatonin is widely used in various sleep-aid supplements (such as gummies, capsules, and tablets). It primarily targets the general population experiencing difficulties falling asleep, poor sleep quality, or frequent waking, helping to regulate the body's internal clock and improve sleep.
Anti-aging and general wellness: Due to its antioxidant and endocrine-regulating properties, melatonin is also incorporated into certain anti-aging or immune-supporting health foods to help mitigate sleep decline and the deterioration of bodily functions associated with aging.
Cosmetics Sector
Skin-brightening and anti-aging skincare: Thanks to its potent antioxidant and free-radical scavenging capabilities, melatonin is widely used in skin-brightening, moisturizing, and anti-aging cosmetics. It helps reduce oxidative damage, delay photo-aging, and improve overall skin condition.
