Why Melatonin Has Become a Core Functional Ingredient for Sleep Support Supplements?

Insomnia is a very common sleep issue among modern people; chronic insomnia disorder affects approximately 10% to 15% of adults worldwide. Prolonged insomnia not only causes nighttime problems—such as difficulty falling asleep, trouble maintaining sleep, and early awakening—but also impairs daytime functioning and reduces quality of life. Furthermore, it significantly increases the risk of conditions such as hypertension, diabetes, cardiovascular disease, and mental health disorders. Melatonin, a sleep hormone responsible for regulating the sleep-wake cycle, is primarily secreted by the pineal gland deep within the brain. Often referred to as the "hormone of darkness," it can be used as a supplement to help address sleep issues like insomnia and jet lag.

I.What is melatonin?

Melatonin is a hormone naturally produced by the body, primarily by the pineal gland in the brain during the dark hours of the evening. Acting as the body's internal "biological clock coordinator," it is synthesized from the amino acid tryptophan:

Tryptophan → Serotonin → Melatonin. Remarkably, plants can also produce melatonin; it has been found in rice, corn, grapes, tomatoes, and coffee beans.

II.What are the benefits of melatonin supplementation?

Melatonin plays a crucial role in the sleep-wake cycle. Under natural conditions, the brain secretes almost no melatonin during the day. Secretion begins gradually in the early evening and accelerates rapidly around 9:00 PM, signaling the brain to initiate sleep. Melatonin helps overcome sleep disorders and improves sleep quality by inducing natural sleep.

Supplementing with melatonin can restore levels to those seen in youth and help reset the body's natural sleep-wake rhythms. It shortens the time spent awake before falling asleep and the time required to actually fall asleep. It also improves sleep quality by significantly reducing the number of awakenings during the night, shortening the light sleep phase, and extending the deep sleep phase.

Advantages over other sleep aids: Ingredients like sour jujube seed (*Ziziphus jujuba*), GABA, and valerian extract primarily offer soothing and calming effects, aiding relaxation indirectly. In contrast, melatonin directly targets the core pathways regulating the body's sleep rhythm; it offers a more targeted approach and is more effective at addressing difficulties falling asleep and disrupted circadian rhythms (such as day-night reversal).

III.Target Groups for Melatonin

The Elderly

Melatonin is a natural sleep-inducing substance produced by the body; a decline in melatonin levels is a root cause of insomnia.

Supplementing with melatonin can restore levels to those found in youth and help reset the body's natural sleep-wake rhythms. It shortens the time spent awake before falling asleep and the time required to actually fall asleep. It also improves sleep quality by significantly reducing the number of awakenings during the night, shortening light sleep phases, and extending deep sleep phases.

Individuals with Poor Sleep Quality

Melatonin improves sleep quality by shortening the time spent awake before falling asleep and the time required to fall asleep, significantly reducing the number of awakenings during the night, shortening light sleep phases, and extending deep sleep phases.

People Experiencing Jet Lag or Shift Work

Melatonin secretion in the human body follows a circadian rhythm, with higher levels produced at night.

IV.Industry Trends

According to reports, the global melatonin supplement market is entering a pivotal phase of large-scale expansion. The market value is projected to grow from $3.3 billion in 2025 to $13.1 billion in 2035, representing a compound annual growth rate (CAGR) of 14.9%. This growth is primarily driven by a shift in consumer health awareness toward prevention and a preference for health supplements and non-pharmaceutical wellness products. Additionally, demand in niche health sectors—such as insomnia management and stress relief—is fueling the growth of the overall market.
