Melatonin Dosage Guide: Is 3mg or 10mg Best for You? | Mattress Miracle
Quick Answer: Research consistently shows that lower doses (0.3mg to 1mg) of melatonin are more effective for sleep timing than high doses (5mg, 10mg, 20mg). High doses can desensitize your brain's receptors, leading to nightmares, next-day grogginess, and reduced effectiveness over time.

You walk into a pharmacy in Brantford and see bottles labeled 3mg, 5mg, 10mg, even 20mg "Extra Strength." Naturally, you assume the higher number is better.
But when it comes to hormones, "more" usually means "messy."
At Mattress Miracle, we aren't doctors, but we help people troubleshoot their sleep every day. One of the most common issues we see is the "Melatonin Rollercoaster",people taking massive doses, sleeping terribly, and then taking even more.
The "Micro-Dose" Revolution
Your body naturally produces about 0.3mg of melatonin per night. That is one-third of one milligram.
When you take a standard 3mg pill, you are taking 10 times your natural level. When you take 10mg, you are taking 30 times natural levels.
The MIT Study
Researchers at MIT found that a dose of just 0.3mg was effective for sleep onset. Doses higher than that stopped working better,they just increased side effects. The supplement industry sells high doses because they can't patent the hormone itself, but they can market "Extra Strength" as a value-add.
Why 10mg Is Often Too Much
Taking 10mg or 20mg floods your brain's receptors. This causes two problems:
- Receptor Downregulation: Your brain says, "Whoa, that's too much signal!" and becomes less sensitive to melatonin. You start needing more to feel anything.
- The Spillover: Your liver cannot clear 10mg quickly. When you wake up 8 hours later, you still have high levels of sleep hormone in your blood. This is the "melatonin hangover",feeling like a zombie until noon.
Is Daily Use Safe?
Short-term daily use (a few months) is generally considered safe for adults. However, long-term data is sparse.
The concern with taking high doses (10mg+) every night for years is that it might downregulate your own natural production. Essentially, your pineal gland gets lazy because the pill is doing the work.
Most sleep specialists recommend using melatonin as a "bridge" to fix a schedule, not a permanent crutch.
Finding Your Magic Number
If you want to use melatonin effectively, ignore the "Extra Strength" label.
- Start with 1mg: Buy a 1mg tablet. Cut it in half. Take 0.5mg 90 minutes before bed.
- Wait 3 Days: Give it time to work. Don't increase the dose immediately.
- Max Out at 3mg: If 3mg doesn't work, 10mg won't fix it. The problem isn't the dose; it's likely your environment or physical comfort.
The Comfort Factor
If you are taking 10mg and still awake, ask yourself: Does my back hurt? Does my shoulder go numb? Melatonin signals sleep, but pain signals "wake up." If your mattress is the issue, no pill will fix it. Come test a Restonic ComfortCare mattress to see if physical support solves what chemical support couldn't.
Frequently Asked Questions
What happens if I take 20mg?
You likely won't die, but you might feel awful. Symptoms include headache, dizziness, nausea, vivid nightmares, and extreme grogginess the next day. It is not recommended.
Can I overdose on gummies?
It is hard to reach a toxic level of melatonin, but it is easy to get sick from the sugar and gelatin in gummies if you eat a whole bottle. Keep them away from children.
Is 5mg okay for a big guy?
Body weight doesn't affect melatonin dosage as much as it does alcohol. It acts on the brain, not the muscles. A 250lb man might only need 0.5mg, just like a 120lb woman.
Does melatonin stop working over time?
If you take high doses, yes. Your receptors get used to it. The solution is usually to stop taking it for a few weeks to "reset" your sensitivity, then restart at a much lower dose.
