As people age, especially after the age of 35, the body's own melatonin secretion decreases significantly, with an average decrease of 10-15% every 10 years, leading to a series of functional disorders such as sleep disorders. The decrease in melatonin levels and reduced sleep are one of the important signs of human brain aging. Melatonin can shorten people's sleep time before bedtime and improve people's sleep quality. For people with insomnia, melatonin can be used to relieve insomnia symptoms. Unsuitable for people: children, pregnant women Usage: Take 1 capsule once a day before bedtime, no more than 2 capsules each time according to your own situation. Or take as directed by a healthcare professional.
