Build Your Evening Routine Around a Natural Transition Into Sleep
Falling asleep does not start when you get into bed. It starts with how your body transitions out of the day.
Melatonin Nasal Spray is designed to be part of your evening Sync Stack, helping signal to your body that it is time to unwind and move into rest. Used consistently, it supports a smoother, more reliable transition into sleep. You can layer your routine based on your needs.
It is not about forcing sleep. It is about creating the conditions that allow it to happen, consistently, naturally, and with less resistance.
How This Formula Supports Your Body's Natural Sleep Signal
Sleep begins with a signal, not a force. Melatonin is a hormone your body naturally produces to indicate that it is time to transition from wakefulness into rest, helping regulate your circadian rhythm. This formula is designed to support that process directly.
The Signal
Melatonin
Melatonin helps reinforce your body's natural sleep signal, supporting a smoother transition into rest without forcing sedation.
The Delivery
Nasal Delivery
Delivered as a nasal spray, the formula is absorbed through the lining of the nose instead of being swallowed like a capsule, so some of each dose skips digestion.
The Support
L-Theanine
L-Theanine helps quiet the mind as you wind down. The only other ingredient is alkaline water.
Support the signal, calm the mind, a system that works with your body.
What You Might Notice When Your Body Gets the Signal
When your body receives the right signal, sleep does not have to be forced. It can begin more easily, more smoothly, and with less resistance. Everyone responds differently, so what you notice may vary.
Fall Asleep Faster and More Easily
Supports your body's natural ability to transition into sleep, so you may spend less time lying awake.
A Quieter, Calmer Mind at Night
Helps reduce mental activity and racing thoughts, making it easier to relax and let go.
A Smoother Transition Into Sleep
Supports a more natural shift from wakefulness to rest, without abrupt or heavy effects.
Less Nighttime Frustration
Helps reduce the cycle of trying to fall asleep, so bedtime feels more effortless and less stressful.
Supports a Healthy Sleep Rhythm
Helps reinforce your body's natural sleep-wake cycle, supporting more consistent sleep patterns over time.
Relaxation Without Grogginess
Supports sleep in a way that feels clean and natural, without the heavy or lingering feeling some sleep aids create.
Every Ingredient Has a Purpose. Nothing Extra.
This formula is designed to support your body's natural transition into sleep, using a small number of targeted ingredients that work together to promote calm, balance, and effective delivery. Each component plays a specific role in helping your system shift from wakefulness into rest.
Melatonin 200 mcg
A naturally occurring hormone that signals to your body that it is time to sleep, helping support a smooth transition from wakefulness into rest.
L-Theanine 17 mg
Supports a calm, relaxed mental state, helping quiet the mind and reduce racing thoughts so your body can more easily transition into sleep.
Other Ingredients: Alkaline Water
The base the melatonin and L-theanine are dissolved in. Nothing else is added.
How to Use Melatonin Nasal Spray for Sleep
One serving is two sprays, one in each nostril, giving 200 mcg of melatonin and 17 mg of L-theanine.
1. Time it. Use it 15 to 30 minutes before your intended bedtime, once you are winding down for the night.
2. Spray. Tilt your head back slightly and breathe in gently as you use one spray in each nostril.
3. Wait. Give it at least 1 to 2 minutes before you blow your nose.
4. Adjust only as the label allows. If half an hour passes and the effect is not strong enough, the label allows one more two-spray serving.
Melatonin works with your body's own sleep signal, so it fits best alongside a dark, quiet room and a regular bedtime. For more on timing and amounts, read our melatonin dosage guide and our guide to sleeping better.
Melatonin Nasal Spray FAQ
Below are our most frequently asked questions about our Melatonin Nasal Spray.
What does melatonin do?
Melatonin is a hormone your body naturally produces to signal that it is time to sleep, helping regulate your internal clock and the transition from wakefulness into rest.
What is a melatonin spray?
A melatonin spray delivers melatonin as a fine mist instead of a pill or gummy. Most melatonin sprays are sprayed into the mouth; ours is a nasal spray, with 200 mcg of melatonin plus L-theanine in each two-spray serving.
Will this make me feel groggy in the morning?
This low-dose formula supports a natural transition into sleep rather than heavy sedation, so most people fall asleep more easily without lingering grogginess.
How quickly does it work?
Many people notice the wind-down signal within minutes when they are ready for sleep.
Is a melatonin spray better than pills or gummies?
A nasal spray is absorbed through the lining of the nose instead of being swallowed like a capsule, so some of each dose skips digestion, and it lets you use a small, measured amount. Our melatonin spray guide compares the formats, and our complete melatonin for sleep guide covers dosing and timing.
How much should I use?
A little melatonin goes a long way, so use as directed and start with the lowest suggested amount before bed.
Is it safe to use nightly?
Low-dose melatonin is widely used and non-habit-forming. Follow the label and check with your healthcare provider if you are pregnant, nursing, or taking medication.
What is the melatonin nasal spray dosage?
The label serving is two sprays, which gives 200 mcg of melatonin and 17 mg of L-theanine. Use it 15 to 30 minutes before your intended bedtime. If half an hour passes and the effect is not strong enough, the label allows one more two-spray serving.
Is intranasal melatonin the same as melatonin nasal spray?
Yes. Intranasal means used in the nose, so intranasal melatonin, nasal melatonin and melatonin nasal spray all describe the same format. Most other melatonin sprays are sprayed into the mouth instead.
How long does one bottle of Melatonin Nasal Spray last?
Every bottle holds 30 two-spray servings, about a month at one serving a night. It runs out sooner on nights you use the optional second serving.
How much does Melatonin Nasal Spray cost per serving?
At the full one-time price of $59 for 30 servings, each serving is about $1.97. A subscription lowers the price, as shown at the top of this page.
How much melatonin is in each spray?
Each spray holds 100 mcg (0.1 mg) of melatonin, so the two-spray serving gives 200 mcg (0.2 mg), along with 17 mg of L-theanine. That is a low amount by design. Check the label before using it alongside any other melatonin product.
When is the best time to use melatonin nasal spray?
Use it 15 to 30 minutes before your intended bedtime, when you are ready to wind down. Keeping the same bedtime each night supports your body's own sleep rhythm.
Do I need a prescription for melatonin nasal spray?
No. You can order Melatonin Nasal Spray directly from this page with no prescription. Check with your healthcare provider first if you are pregnant, nursing or taking medication.
You're Not Bad at Sleeping. Your Body Isn't Getting the Signal.
If you have ever laid in bed feeling tired, but unable to fall asleep, you know how frustrating it can be. Your body is ready. But your mind will not slow down. Or something just is not clicking.
That is not a lack of discipline or routine. Sleep is a biological process, and it starts with a signal. Your body relies on internal cues to know when it is time to shift from alertness into rest. One of the most important of those signals is melatonin. When that signal is delayed, disrupted, or out of sync, your body can feel tired, but not ready for sleep. So you stay awake longer than you should. Thinking. Waiting. Trying.
This is not something you force. It is something your body needs help initiating.
When that signal is supported, sleep does not have to be chased. It begins naturally.
