Functional food for improving endogenous melatonin secretion rhythm and functional food for improving circadian rhythm

摘要

Phase adjustment or amplitude of endogenous melatonin secretion rhythm that can be used on a daily basis, is safe, and can effectively prevent or ameliorate endogenous melatonin secretion rhythm disorders and circadian rhythm disorders without ingesting exogenous melatonin Provided are a potentiating agent, a circadian rhythm improving agent, and a functional food capable of preventing or ameliorating various symptoms such as a sleep disorder and a sleep latency disorder using the same. The endogenous melatonin secretion rhythm phase adjusting or amplitude enhancing agent and circadian rhythm improving agent of the present invention contains whey as an active ingredient, and the endogenous melatonin secretion rhythm improving functional food of the present invention is the endogenous melatonin The functional food for improving circadian rhythm according to the present invention contains a secretory rhythm phase adjusting or amplitude enhancer, and the circadian rhythm improving agent of the present invention.
