For anyone taking Melatonin as a sleeping aid: The dosages it is being sold at are way too high. Recent studies point to 0.3 mg being the right amount for adults [1].

That dosage (taken over a period of several months every day at the same time) helped me get through a period of insomnia last summer, when basically all the other medications failed or had too strong side effects.

> administering melatonin prior to exposure to UV radiation increases cell survival and reduces oxidative damage. Topical melatonin applied to skin 15 minutes prior to exposure to UV radiation completely prevented skin redness (erythema) in a small randomized double-blind study of human subjects This isn't necessarily good news. Sun burn is your body's way of reducing skin cancer. When your body detects too much expo…

Are you saying this as a medical research professional or just spitballing? Because the article send to be straightforwardly claiming that melatonin is reducing oxidative damage, not just disabling the visible effects. One of the referenced sources is entitled, "Melatonin as a major skin protectant: from free radical scavenging to DNA damage repair," which seems to be saying that the "more research needed" has alread…

Free radical damage is not the main mechanism of UV-induced DNA damage. The main mechanism is direct dimerization as the photo-excited electron relaxes.

Melatonin works mildly well for me for a few days, but quickly stops working again, which is unfortunate. I will admit I also have some anxiety issues I need to work on. For better or worse, a low dose of diphenhydramine hcl (12mg) has continued working for me for over a decade without needing to up the dose. My personal experience as far as habit forming goes: I only take it on work nights, and sleep just fine on we…

The problem with is diphenhydramine is the increased Alzheimer's risk: https://www.health.harvard.edu/blog/common-anticholinergic-d...

Lack of sleep is also terrible for your health in so many ways though, and is also associated with Alzheimers. Of course antihistamines decreases your sleep quality but if it helps you get through rough patches I think it's a good alternative.

Taking it every day for years though is probably not a good idea.

They do sell melatonin in correct dosages too, Sundown Naturals 300mcg is the one I use.

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...

What a waste. You can buy premade 300mcg melatonin pills for $0.03/pill (Sundown Naturals on iHerb), so the time you spend measuring melatonin yourself is just wasted time.

I once asked about melatonin in a health food shop and was told it’s illegal in the UK! The seems odd in a country where (for example) you can buy codeine pills over-the-counter, so now I’m curious about why it was banned, considering it’s reported to have few side effects?

Note that the codeine you can buy OTC is very weak, and compounded with paracetamol (acetaminophen).

“Any” seems incredibly implausible. Class A drugs have penalties for mere possession.

Drugs as those which are controlled under the Medicines Act not by the Misuse of Drugs Act. There is no limit on importing POM for self use, the violation only happens if you distribute them without a prescription.

Just in case it's not totally clear for anyone reading this - it is illegal in the UK to import drugs controlled under the Misuse of Drugs Act, even if they are also licensed medicines.

The cynical answer is that sleep medications (and I mean the more highly scheduled varieties) are among the biggest pharmacological money spinners. Melatonin is cheap and unpatentable (although there was several attempts at melatonin mimetics, e.g. agomelatine). It's unfathomable that melatonin is available only on prescription (and has become increasingly hard to obtain). I think the toxicity is close to water... one would be more likely to gag on the number of pills necessary to O.D. and I'm not sure if there's even a single melatonin related death on record.

The only problem is that the suggest 3 mg a day to get the effects of the study.
