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...

This! All of this! So many people do not realize that melatonin is a HORMONE! Do not create an imbalance to your developing child’s hormones! Magnesium > 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

Andrew Huberman had a pretty strong take on melatonin on JRE. He doesn’t recommend it for sleep. High melatonin levels suppress puberty in kids. In animal studies, giving it to male hamsters made their testes shrink from marble-sized to rice-grain-sized in just one week. Females’ ovaries basically shriveled. It might knock you out at first, but it often wears off after a few hours, leaving you staring at the ceiling. And there are real concerns about what it does to testosterone and estrogen balance. I always thought melatonin was harmless because it’s “natural,” but this made me pause. Sleep is everything, but if a popular supplement is messing with hormones without even delivering deep, quality rest, we should probably be smarter about it. What do you use to help you sleep?

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?

My top five tips to battle jet lag. 1. Early morning bright light exposure - This must be outside light from the sun. Aim for 30 minutes minimum. Light is the strongest zeitgeber that synchronizes the brain and body with the time zone you are in and resets your biological clock. The bright light signals to the brain that it's morning and time to wake up, and also activates the cortisol awakening response and inhibits melatonin production. 2. Exercise - Another zeitgeber that helps realign your circadian rhythm (your internal clock). Plus, it's great for your health. 3. High-dose creatine - Creatine can help support brain health in the context of stress. Jet lag is a big stress in the brain. Creatine starts to accumulate in the brain at a dose of 10g per day, and studies have found that 20-25g of creatine can improve brain function in the context of sleep deprivation. May not work for everyone but it works for me. 4. Strategic melatonin timing - A small dose of melatonin a couple of hours before you want to sleep helps signal to the brain it’s time to get ready for bed. This really helps when your internal clock thinks it is still daytime. 5. Avoid blue light exposure during the evening - Blue light inhibits melatonin, which is the last thing you want to do in the evening. Melatonin is the hormone that helps make you feel ready to sleep. Dimming lights or blue light-blocking glasses do the trick.

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 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

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.

If you’ve tried everything—melatonin, magnesium, breathwork, and still can’t sleep, this might be what you’re missing. I started using Hapbee, and it’s a total game-changer. On my 8-hour flight from Dubai, I set it to sleep mode and woke up 8 hours and 2 minutes later, fully rested. No supplements, no grogginess—just deep, natural sleep. Here’s how it works: ✅ Goes under your pillow—no wires, no weird sounds ✅ Uses frequency technology to mimic melatonin, adenosine & even caffeine without actually taking them ✅ Turn it off & the effect stops instantly—no lingering side effects You can even use the caffeine setting in the morning for a boost without drinking coffee Are you giving it a try?

Bryan Johnson reveals what you MUST do to get the best sleep possible ''Reading a book for 10 minutes before bed is as powerful as sleep medication, on some metrics it's even more powerful than sleep meds'' ''Have your final meal of the day 4 hours before bed, it gives your body time to digest, and when your body has that distance it will lower its body temperature, your blood glucose will be down, melatonin is produced and it gets the body in a more relaxed state'' ''You need like an hour wind down routine, if your bedtime is 10 PM, when 9 PM comes turn off all the screens and spend that hour doing things that relax you, read a book, breath work, meditation, hang out with a friend, anything but be on your screen''

Honey is a dream remedy for sleep, it contains tryptophan, which produces serotonin, which then promotes relaxation. When we are in the dark, our body uses serotonin to produce melatonin! Salt has many anti-stress and anti-excitatory qualities, making it a great addition to help lower any stress hormone spikes, and balance those stress hormones. Sleep disturbances are commonly caused by an increase of stress hormones that rush through the body around 2am-4am. Honey provides a stable amount of simple sugars that the liver uses almost entirely for glycogen synthesis, which prevents our adrenals from pumping out excess cortisol. Tried it and it doesn’t work? Cortisol may not be why you are having disturbed sleep 💓 It’s simple! Mix 1 tbsp of salt in 5 tbsp of raw honey. Place a pea sized amount under your tongue and let it dissolve. This is a great hack while you are addressing the root cause of sleep issues!
