I know a lot of people who take melatonin to fall asleep. Trying to understand if that's good or bad here?

I have heard that the main questionmark is that typical doses are far larger than your body would normally produce, so you can't just assume it's "normal" or "natural".

But nobody has really identified harm yet.

Tangentially I'm interested to know whether taking melatonin for long periods of time (years) reduces its effectiveness. I've been taking it for nearly a year but I've heard stories about how you need to keep increasing the dose to get the same effect.

Indeed melatonin supplementation causes tolerance development. The correct dose to avoid it is 0.3 mg [1]. Nevertheless I'm glad pharmacies sell pills with much higher dosage - you can just buy the 2-10mg pills, crush them and take the dose you need. I bet they would sell 0.3 mg pills for the same high price if they knew. [1] https://slatestarcodex.com/2018/07/10/melatonin-much-more-th...

I had no choice but to downvote for the greater good.

I have chronic insomnia, I had it all my life. I used to use melatonin but yes over time it lost its effect and melatonin is not one of those drugs you can just take more to sleep. It has a very precise dosage and if you take more it doesn't make you more sleepy. If you have chronic insomnia, you need to solve the root cause. In my case it is anxiety, and currently I'm trying to solve my anxiety and my sleep quality…

I take doxylamine succinate 5-10 mg about an hour before bed and find that it helps with sleep much more than melatonin, which only seemed to help with a very time-limited form of tiredness (it wore off and I'd wake up). Still, even the antihistamine (sold as a sleep aid) can't do all the work when something big is going down the next day. Like a meeting with a big client requiring a lot of travel. A big stressor mus…

Doxylamine succinate is a potent anticholinergic drug, as are (IIRC) all other OTC antihistamines that cause drowsiness. Long term use of such drugs have been linked to dementia later in life. I would at least read some of the literature and re-evaluate whether using drugs like this to sleep on a regular basis is worthwhile.

Nothing is bad in melatonin except the tolerance development. If I wasn't afraid of developing tolerance to endogenous melatonin I would take huge doses of it every evening.

I find small doses work better than huge doses anyhow.

The writing idea is solid - thanks for sharing! You should try weighted blankets if you haven't already.

I don't have specific knowledge to counter this, but am surprised. It implies that humans would need more melatonin over the course of their lives, yet they produce less and less as they age...

Already done. No dementia in family history, and the actual literature leaves much to be desired in terms of qualitative result.

By the way I discourage the use of the term "linked" in light conversation as it has recently and unfortunately become a socio-culturally appropriated term indicating proof of causality. That a linkage exists often means far less than most people think, and this could immediately impact their health-related decision-making for the worse.

You are welcome. I have found that the presence of two cats, one on either side of my body, pinning me into bed, extends my nap time for the better. At nighttime though, a weighted blanket would probably be just the thing! I appreciate the recommendation.
