A recent study indicates standard melatonin doses (2-3mg) taken shortly before bed have no impact on sleep. 4mg taken 3 hours prior shows benefits. Melatonin is ineffective for insomnia. #Melatonin #SleepScience

A study shows 88% of melatonin brands have inaccurate labels, with melatonin content ranging from 26% less to 347% more than claimed. Look for brands with 3rd-party tested batches. It's a chronobiotic, not a sleep aid. #SleepScience #Melatonin

A recent study associated melatonin with an 89% higher risk of heart failure, but this is likely an association, not causation. Poor sleep, which melatonin users often try to correct, is the real culprit. #Melatonin #HeartHealth

Stop downing melatonin like candy. Andrew Huberman is sounding the alarm: High-dose melatonin supplements (20mg, 50mg — yes, people actually take that much) can suppress the hypothalamic-gonadal axis and potentially delay puberty and adolescence, especially in young people. While melatonin is naturally produced in many cells and has antioxidant properties, flooding your system with large supplemental amounts is a bad idea. His practical take: maybe a tiny bit occasionally, but not the mega-doses you see everywhere. It’s a timely reality check for anyone relying on melatonin nightly to fall asleep. Have you ever taken high-dose melatonin? Did it help or cause any weird side effects?

Sleep doctor says taking melatonin without understanding what it does can cause serious harm to your body “Melatonin is by prescription only almost everywhere outside the United States. Melatonin is a hormone. There’s a reason you can’t go to CVS and get testosterone and estrogen, right? Hormones affect the entire system. What you don’t want to do is have somebody just willy-nilly grabbing a hormone and starting to take it without understanding what’s going on with them” “More importantly, melatonin in particular interacts with SSRI medications. An SSRI is a serotonin-specific reuptake inhibitor, an antidepressant, things like Prozac, Zoloft, and Celexa. All of those are medications that can be affected by melatonin ingestion. In addition, melatonin can affect birth control, blood pressure medication, and diabetes medication” “Melatonin is a sleep regulator, not a sleep initiator. Melatonin doesn’t affect sleep drive, it affects sleep rhythm. It mainly affects your brain, telling it when it’s time to go to bed. It does not directly make you sleepy”

Matthew Walker, the UC Berkeley scientist behind "Why We Sleep," found an hour of screens before bed delays melatonin, your sleep hormone, by ~3 hours. That's why you lie there wired and cortisol won't power down. 7 ways to fix your sleep: 1. Kill bright screens before bed.

Does using melatonin raise heart failure risk? A preliminary (not peer-reviewed) conference abstract reported that adults with insomnia with ≥1 year of documented melatonin use had a 90% higher 5-year rate of heart failure and 3.5x more hospitalizations than adults without a documented use of melatonin. There are some major caveats: this is observational (an association, not causation), the database mixed countries where melatonin is over-the-counter vs prescription, and insomnia severity and other psychiatric conditions weren’t captured. Importantly, randomized trials in people with established heart failure show no harm from melatonin use and some signals of benefit including better quality of life and improved ejection fraction. This is an interesting real-world signal that merits peer review and careful follow-up, but it is not proof that melatonin causes heart failure.

7/ After Sun Down, Minimize Evening Light Blue light suppresses melatonin secretion and can disrupt your circadian rhythm. Other types of light can also impact melatonin to varying degrees. + Install dimmer switches and use low, warm lighting + Wear blue light-blocking glasses 2-3 hours before bed + Enable night mode on all devices or install blue light filters + Red light is best (red bulb + lamp ftw) And remember to limit screen time *at least* an hour before bed and blackout your bedroom. Use this time for your 30-60 min wind down routine.
