For over 100 years, science has recognized Melatonin as your body's natural sleep hormone. It controls our circadian rhythm and regulates sleep timing or our sleep/wake cycle. Its presence lets us sleep on demand naturally.

It's proven science, and Melatonin is released naturally in all of us. During the day, in the presence of poor schedule, anxiety, or stress, Melatonin disappears to an untraceable level.

When you feel sleepy, that's Melatonin. But, if you have trouble falling asleep, wake up during the night, or work abnormal hours, Melatonin is being disrupted and is preventing a great night of deep and restful sleep.


In a study from the US National Library of Medicine, experts recommend taking Melatonin tablets two hours before bedtime.

It must go through our digestive system, taking hours to be fully absorbed. If you can't sleep in the middle of the night and you need assistance right now, then oral medication just isn't the option.

The bioavailability of oral tablets or the rate at which it's absorbed into your system is less than 25%. Leading to dosage issues and most going to waste.

Melatonin tablets can be quite ineffective, at incorrect doses, often leading to daytime grogginess.


Sleep Now™ is your all-natural personal aromatherapy diffuser designed for inhalation, delivering a safe and fast-acting infusion of a unique blend primarily of Melatonin, Chamomile, and Lavender—allowing you to feel the effects instantly.

Shipping? Delivery time?

Zenko Health® aims to deliver your package within 3-5 business days from our own United States warehouse located in Phoenix, Arizona.

We also ship internationally to anywhere around the world! So, for example, we regularly ship outside the US to Canada and a few other selected countries like Australia.

We love our international customers very much! However, delivery is a little longer and usually takes around 7-12 days.

We do charge a small shipping cost for US customers and a flat rate fee for International customers. The fee changes slightly based on the country, but it only covers what we must pay our shipping company.

How do you use it?
  • 1. Remove the rubber cap.
  • 2. Inhale for 1-2 seconds through your mouth,
    like sucking on a straw, then exhale out of your nose.
  • 3. Repeat 5-10+ times and use 5-10 mins before bedtime.

Melatonin will be absorbed immediately into your body, creating a quick effect.

How long will it last?

It depends on how often you use it.

Each diffuser has a life of around one month.

That is if used every night, with the recommended 5-10+ inhalations, and the diffuser has a capacity of around 400 inhalations.

We have special BUY 2 GET 1 FREE and BUY 3 GET 3 FREE offers at the moment. So when buying three, you can get three free, thus getting them for $10 each.

Each diffuser can last between 30+ nights when used every night. So the cost per use can be as low as $0.3 per night, depending on how aggressively you use it.

How much Melatonin per dose?

Each diffuser contains 50mg of Melatonin. So, with around 400 inhalations per diffuser. It's around 0.125mg per inhalation.

However, keep in mind only around 25% gets absorbed with oral tablets as it has to go through your digestive system. Our diffuser is a much more efficient delivery mechanism, and a lot more is absorbed and quicker. So, in turn, a lot less is needed.

We recommend 5-10 inhalations per night. However, you’re free to have more than 10 inhalations per night and find your sweet spot.

Roughly speaking, and for the sole job of comparison, 5-10 inhalations are equivalent to around 3-5mg in oral Melatonin tablets, in line with the recommended dose for oral Melatonin tablets.

Why take Melatonin this way?

Oral medication must pass through our digestive system and metabolism. It's a well known ineffective way to get compounds into the human body. With oral medication, less than 25% actually makes it into your body and can take 1-2 hours to fully take effect.

Sleep Now™ diffuses Melatonin directly into your bloodstream without going through your digestive system. It allows you to control dosing better and feel the effects immediately.

What is Melatonin?

For over 100 years, science has known Melatonin controls our circadian rhythm and regulates sleep timing or our sleep/wake cycle; when we go to sleep and wake up.

It's proven science, and Melatonin is released every night in every one of us.

Melatonin is the primary natural ingredient that pushes us into the most restful form of deep sleep. It can be interrupted by light, indoor environments, travel, poor schedule, anxiety and stress.

Many don't produce enough Melatonin, causing sleep problems. Studies show that Melatonin can lengthen total sleep time, shorten the time it takes to fall asleep and enhance sleep quality.

Sleep Now™ diffuses Melatonin directly into our body without going through our digestive system, helping us get into the deepest form of restful sleep.

Is there an age limit?

Sleep Now™ doesn't contain any harmful chemicals. Nevertheless, this product is not recommended for people under the age of 18, pregnant woman, or those sensitive to listed ingredients.
