Can melatonin have side effects?

Are you struggling with sleep? Finding it hard to get enough rest at night or stay asleep throughout the night? You’re not alone. Millions of people in the world suffer from insomnia and other sleep disorders, leading them to turn to melatonin supplementation as a solution.

However, like most things in life, there are side effects associated with using melatonin supplements. To make an informed decision, you must understand what these side effects are and how they might affect your body.

So grab a cup of coffee or tea and let’s explore whether melatonin can have any nasty side effects.

What Is Melatonin?

Before we dive into the possible side effects associated with melatonin usage, let’s first answer one critical question: what is melatonin?

Melatonin is a naturally occurring hormone produced by our bodies that regulates our wake-sleep cycle (circadian rhythm). The hormone plays an important role in helping us fall asleep once darkness sets in and adjust to different time zones when traveling across countries – making it no surprise why many consider taking supplemental dosage during prolonged travels.

However,as we will discover later, too much of this supplement isn’t always great for our health.

How Does Melatonin Work?

Melatonin works mainly on two receptors known as MT1 and MT2 receptors located inside the hypothalamic cells present within our brain (Don’t worry about trying to memorize these terms; there won’t be a test).

Once activated by exposure to darkness (the absence of light), pineal gland starts creating more levels of hormones such as serotonin which would convert further into N-acetylserotonin NH_2 (NAS) and then synthesizes more concentration based on biological preferences. So essentially melantonin intake elevates level concentration above normal baseline levels ——making sure humans rely significantly less upon opioids that keep us awake & amp up/hype up regular inflammation.

As a result of this, the body’s temperature begins to drop down slightly and drowsiness starts setting in (which is very handy if you’ve ever had trouble getting to sleep). The science behind it can be both fascinating and overwhelming at times.

What Are The Side Effects Of Melatonin Use?

Melatonin has several side effects that users might experience following administration of supplements noted below:

Daytime Sleepiness

Commonly referred to as oversleeping, daytime sleepiness is one potential side effect of melatonin use. When there’s an increase in concentration levels of this hormone inside our bodies, people may end up feeling groggy or even confused during their waking hours.


Another common side effect that some folks taking melatonin supplements may suffer from are headaches—not just any headache. More like a tension headache with throbbing pain on both sides within your skull.


According to various studies conducted across different geographic regions worldwide; nausea was reported another possible effects occurring after ingesting too much artificial melatonin consumption.

Vivid Dreams

Some individuals report experiencing vivid dreams which can feel overly real upon wakening – potentially leading them into confusion for short bursts when they first wake up each day.

Visual Hallucinations

Similarly poignant hallucinations such as seeing illusions could occur during such experiences- Luckily these instances are reportedly rare but still something recommended not being ignored by professionals/practitioners

Each individual maybe affected differently due regarding variables such as age etcetera factors making medication efficient causes absolutely zero guarantee surrounding outcomes so we recommend proceeding cautiously throughout entire therapeutic process using medical personnel boundaries where necessary protecting/bolstering success rate/results rates!

How Much Melatonin Should You Take?

The ideal doses should vary between patients depending primarily maintaining solid goals/objectives keeping healthy habits/behaviors – typically ranging anywhere between 0.2mg right upto 10 mg alongside proper monitoring service (which might take several weeks); So here’s the thought on how to get started safely:

Name Dosage Timing

Adults Recommended between .1 – .5 mg, If needed assess going unto up to 6 mg total daily dosage limit if unable obtain optimal results which will depend varying drastically based genetic and lifestyle harmony checks can be advantageous looking at larger figures Example being maintaining balance/adjusting for time-zone difference or for extended travels each individual success rate is up to their unique experience guidelines levels difference ranging from person-to-person Before increasing dosage talk with trusted medical personnel/practitioners!

A Word Of Caution

Taking melatonin at high doses may cause some unwanted side-effects mentioned above like dizziness, fatigue & confusion; Instead commonly recommend starting out observing a lower level dose-response baseline until one knows exactly what they’re dealing with /know what works best for them.


In conclusion, Melatonin supplements have shown great prospect when it comes improving sleep duration and quality across different groups demographics however those potential gains might come with surprising side effects too recommended users do the adequate research alongside approaching their respective doctor before commencing treatment regimen journey staying vigilant against any possible health complications or symptoms arising in response to attempted intervention remedies.
