“Because of its potent antioxidant effects, melatonin’s benefits extend to cardiovascular protection and cellular health. Its wide-reaching effects make it critical for much more than just a good night’s sleep.”

“She reviews possible adverse effects such as morning grogginess, daytime sleepiness, headache, and feeling cold or developing hypothermia. Melatonin can interact with blood thinners and other prescription drugs, so dose and timing require clinical review when these apply.”

“In this FoundMyFitness interview, Dr. Michael Grandner explains that melatonin primarily signals biological night rather than acting like a conventional sedative. A meta-analysis of 19 randomized trials involving 1,683 participants found modest average improvements, including about seven minutes less time to fall asleep and eight minutes more total sleep.”

“While there are no human clinical studies evaluating the effectiveness of melatonin for COVID-19, melatonin has been shown to prevent acute lung injury and acute respiratory distress syndrome due to viral infection in animal studies.”

“The study's electronic health record design makes exposure classification especially important. Melatonin is prescription-only in some countries but sold over the counter in the United States, so regular use may never appear in a medical record.”

“In fact, the greatest influence on its secretion is light: generally, melatonin levels are low during the day and high during the night. But melatonin doesn't regulate sleep alone.”

“The increasing popularity of melatonin as a sleep aid may be due to its lower side effect profile than other sleeping medications. In this clip, Dr. Satchin Panda describes the pharmacokinetics and possible benefits and drawbacks of taking supplemental melatonin.”

“Therefore, dimming lights and avoiding devices in the evening allows melatonin to rise naturally. Conversely, morning bright light exposure suppresses already-declining melatonin levels, improving alertness and resetting the circadian clock.”

“These photoreceptive cells do not participate in vision; rather, they contain melanopsin, a light-sensitive protein. Melanopsin-containing cells respond to light (or its absence) and direct the master circadian clock to suppress (or release) melatonin.”

Dr. Rhonda Patrick explores melatonin's antioxidant properties, curcumin supplementation, antinutrients, and SARMs in her latest Q&A.
