“However, creatine may become a sleep supplement under certain conditions, particularly those involving a significant cognitive or physiological stress. For example, when creatine is taken before sleep deprivation, it improves cognitive performance, enhances brain energy levels, and reduces fatigue the next day.”

“Magnesium also enhances the activity of serotonin N-acetyltransferase, an enzyme required for melatonin synthesis, potentially improving sleep. Interestingly, sleep deprivation markedly depletes magnesium levels, but whether these alterations create a vicious cycle of sleep impairments is unclear.”

“In work using the Women's Health Initiative and other cohorts, people with sleep disruptions showed increased epigenetic age. One study analyzed 2,078 postmenopausal women from the Women's Health Initiative, with an average age of 65 years.”

“Evidence suggests it influences sleep by regulating neurotransmitters in the brain such as gamma aminobutyric acid (GABA) and acetylcholine. Epigallocatechin gallate (EGCG) is found in tea. It exerts potent antioxidant, anti-cancer, and anti-proliferative properties.”

“Circadian rhythms, the body's 24-hour biological, hormonal, and behavioral cycles, modulate various physiological processes, including producing hormones that regulate sleep, hunger, metabolism, and others.”

“Cognitive behavioral therapy and meditation are effective strategies for managing stress and may result in improved sleep. In this clip, Dr. Matthew Walker discusses how anxiety affects sleep and identifies ways to manage that stress to improve sleep.”

“During sleep, fluid volume in the brain increases to dilute waste and exchange cerebrospinal fluid with plasma from the bloodstream. Enlarged perivascular spaces and poor sleep are both common in people with Alzheimer's disease and other neurodegenerative diseases.”

“Caffeine has a powerful effect on circadian rhythms. Consuming caffeine late in the day disrupts natural melatonin production, compromises sleep quality, and potentially induces chronic circadian misalignment.”

“Such findings could have relevance for future sleep studies, especially those aimed at improving sleep quality for people with insomnia. Link to full publication. Learn more about sleep in this episode featuring sleep expert Dr. Matthew Walker.”

“A small randomized trial in trained athletes found that 20 milligrams per day for two weeks increased total antioxidant capacity and glutathione peroxidase and reduced post-training DNA damage versus placebo; it did not test performance or long-term adaptation.”
