Analysis of Active Ingredients and Mechanisms of Action in Sleep Supplements: A Study Based on Market Conditions

In recent years, with increasing attention to sleep quality, the market has seen a surge in supplements claiming to improve sleep. However, consumers often lack scientific guidance when purchasing these products. This paper aims to systematically analyze the active ingredients and mechanisms of action in various sleep supplements to provide scientific references. Through literature review and experimental research, this study identifies several common ingredients such as melatonin, valerian root, and schisandra that have shown some effectiveness in improving sleep quality. Additionally, the paper explores the mechanisms of these ingredients, including their regulatory effects on the central nervous system, influence on neurotransmitters, and antioxidant functions. The results indicate that different ingredients have varying effects on sleep improvement, influenced by factors such as dosage, duration of use, and individual differences. Finally, the paper suggests that consumers should base their choice and use of sleep supplements on scientific evidence and their personal conditions to achieve the best results in improving sleep quality.
