Herbal Extracts: Herbal extracts are among the most widely used sedative and sleep aid ingredients due to their natural origin, safety, and low risk of dependence. Common examples include valerian root, passionflower, hops, and lemon balm. These plants contain active compounds that regulate the nervous system and promote relaxation.
Amino Acids and Neurotransmitters: This category mainly includes ingredients such as GABA and L-theanine. They act directly on the central nervous system, modulating the release and activity of neurotransmitters to achieve calming, anti-anxiety, and sleep-promoting effects.
Hormones: Hormonal ingredients, represented by melatonin, can directly regulate the body's biological clock and sleep-wake cycle. They are especially suitable for people with sleep problems caused by circadian rhythm disruptions, such as jet lag or shift work.
Minerals and Vitamins: Minerals and vitamins such as magnesium and vitamin B6 have also been shown to be closely related to sleep quality. They help improve sleep by participating in neurotransmitter synthesis or regulating nervous system functions.
Other Functional Ingredients: Ingredients such as 5-hydroxytryptophan (5-HTP), which are precursors to neurotransmitters, can promote the production of serotonin and other neurotransmitters related to mood and sleep.
