Instant Melatonin Spray Review – An Overview

Like we had already mentioned, this is a supplement designed to help you get a restful sleep. It does this by boosting your melatonin levels. And as you might already know, melatonin is a vital sleep hormone.

Naturally, melatonin production tends to reduce when you’re stressed or when exposed to blue light for long hours.

And so, by ensuring that you have adequate quantities of this hormone in your system, this sprayable product builds your natural desire to rest and sleep. Well, at least in theory.

What’s more? The product is available in two different flavors including lavender and mint. So, it’s up to you to decide which breath-freshening flavor you might like.

Who Manufactures It?

The company behind this product is none other than the good old Onnit Labs. They’re based in Austin Texas and have been in operation since 2010.

Over the years, they have released many different supplements. Their Alpha Brain cognitive enhancer (see review) is probably the best known one of them.

They also have a gym. Yup, you read that right – a physical gym.

Generally, the Onnit brand is seems to target anyone who likes to lead an active lifestyle. That said, they’re also quite popular in the Silicon Valley especially among the tech gurus and startup managers.

Whew! That was a mouthful. Sorry if it sounded like an infomercial. That’s pretty much all we know about this brand so far based on our past interaction with their products, past clients, social media platforms etc.

How Instant Melatonin Works

Part of the reason most people find it hard to fall asleep is due to being exposed to blue light wavelengths. As it turns out, the body is designed to generate more melatonin in darkness.

Therefore, when you’re exposed to blue light, your body will stay alert because of reduced levels of melatonin.

Apparently, high-frequency blue light has been clinically shown to interfere with the production of melatonin. And when this happens, you are bound to have trouble falling asleep. That’s why it is advisable not to watch an electronic screen like the one in your PC or smartphone before bedtime.

However, using Instant Melatonin Spray may help the body to notify you when you’re ready to sleep. The spray works by increasing this vital sleep hormone making your body go to a hibernate mode. And eventually, you’l feel sleepy enough to hit the bed.


As far as its ingredients are concerned, this supplement only has one active ingredient which is of course melatonin. It contains only 3mg of melatonin per serving.

Instant Melatonin Ingredients

Other Ingredients

Since this dietary supplement is available in two flavors, each contains extra ingredients besides the 3mg of melatonin. For instance, the Lavender flavor includes ingredients like stevia leaf extract, ethyl alcohol, water, natural citrus extract, lavender oil, and glycerin.

For the fresh mint flavor, its other ingredients are natural citrus extract, water, ethyl alcohol, glycerin, and natural flavors.

How to use it

Adults are advised to take just six sprays at least an hour before going to sleep. However, medical professionals warn against taking more than 5mg of melatonin a night as it could lead to serious side effects.

Additionally, if you’re pregnant, nursing, or taking medications, you need to consult a doctor before using this spray.

Also, it is NSF-certified (this is an accredited and independent non-governmental organization) as safe even for professional athletes.

However, consuming more than 5mg of melatonin could bring about a few negative side effects including:

-Headaches and dizziness

-Short-term depression


-Stomach cramps

-Daytime sleepiness
