This is a game changer

I really didn't expect much from the sleep now diffuser but I had tried everything along with sleeping medication from the Dr's, I tried to use the medication from the Dr's only a couple of times a week dud to them leaving ne groggy the next day, like I said I've tried loads of different things and thought I'd give the sleep now diffuser a go ......so glad I gave it a try , this is a game changer I absolutely love it, I've slept so well with very little broken sleep over this last week, I've already recommended the sleep now diffuser to family and friends . I will definitely be buying these jn the future 😌

Sleep now defusser

I only get 1 to 2hrs per night sleep and it's been like that for around 20yrs, then I seen this advert for sleep now diffuser and my gosh what a difference this product is, I sleep around 6 to 7hrs sleep using this diffuser I've had sleeping pills and patches which worked but I would feel very groggy the next day, with sleep now diffuser I wake up feeling fresh and wide awake I never do reviews but I think this product was worth reviewing 💯 I HIGHLY RECOMMEND this product, I call it magic in a pen

I’ve struggled for years to get a good nights sleep. Having used different sleep aids, nothing really worked. I came across Sleep Now Diffusers, and thought I’d give them a go. 4 years later I’m still using them, and they really do help with drifting off to sleep and not waking up too much during the night. Highly recommended.

Great product, delivery is improving

Update: thanks to excellent customer service, I have received my order. It indeed seems to have been an unfortunate succession of things gone wrong at the couriers side.

Original review:
Don't get me wrong, the product is great, it helped me fall asleep quicker and it tastes great. However, I'm a UK customer and both times I ordered, the package was lost, and then resent. The second order was delivered to the wrong address as I can see on the delivery photo (not my building). Zenko's customer service (which is great too!) asked me to contact the courier myself which was impossible, so I lost almost 90 pound worth of product :(. So I advise Zenko to look at their international delivery set-up to prevent further dissatisfied customers.

Hi Roeland,

Thank you for taking the time to leave such a detailed and honest review. We’re genuinely pleased to hear that you love the product itself and that it’s been helping you fall asleep faster — that feedback truly means a lot to us.

We’re also very sorry for the frustration caused by the delivery issues with your UK orders. We want to clarify for you — and for anyone reading this — that your experience is not representative of our normal shipping performance in the United Kingdom. We successfully deliver to UK customers every day without issue, which is why this situation has been particularly unusual and disappointing for us as well.

In this case, the repeated misrouting and incorrect delivery by the courier (including delivery photos showing the wrong address) is unfortunately outside of our direct control. That said, we take full responsibility for ensuring you receive your order. Zenko Health guarantees delivery of every purchase, and we would never leave a customer without their product — ever.

We’ve been in contact with you and have already offered to arrange another resend, as well as explore an alternative delivery address to ensure successful delivery. We’re currently awaiting your response so we can move forward and resolve this as quickly as possible. Please rest assured, this matter remains open on our end and we are ready to proceed as soon as we hear back from you.

We also truly appreciate your feedback regarding international delivery, and we’re using this experience to further review and strengthen our shipping processes.

Thank you again for your patience and for acknowledging our customer service. We know you enjoy Sleep Now™, and we’re committed to making this right.

Warm regards,
The Zenko Health Team

I tried the Sleep Now melatonin diffuser and I’m very happy with it.

I had problems sleeping before and I tried magnesium, but it didn’t really help me.

I work night shifts, and Sleep Now helps me sleep better and recover faster.

I feel much better after using it and I would definitely recommend it

Not a game changer for me

I thought this just might be the product for me as I have tried many things in the past i.e. tea, CBT, herbal over the counter remedies and it didn't live up to expectations. I have followed all the instructions and even watched the instruction video but this simply didn't work. I think their marketing is excellent on the plus side.

Hi Shaz,

Thanks for taking the time to share your thoughts.

We're genuinely sorry to hear that Sleep Now™ didn’t deliver the results you were hoping for. While it has helped tens of thousands of customers get a better night’s rest — many of whom have left glowing reviews — we completely understand that not every product works the same way for every individual.

Tolerance to natural ingredients like Melatonin, Lavender, and Chamomile can vary quite a bit from person to person, and sometimes even small adjustments can make a meaningful difference. That’s why we always recommend experimenting within our usage guidelines — whether it's adjusting the timing (10–60 minutes before bed), increasing or fine-tuning the number of inhalations, or ensuring the proper inhalation technique is used (like the additional breath and slow exhale, which help with comfort and absorption).

We know you mentioned following the instructions, and we truly appreciate that — but based on feedback from other users, even subtle tweaks in routine have transformed their results. We’d encourage giving it another go if you're open to it.

Thanks again for your honest feedback — it’s always helpful for others considering our product, and for us as a brand to continue learning and improving.

⭐️⭐️⭐️⭐️⭐️ Life-Changing for My Sleep!

⭐️⭐️⭐️⭐️⭐️ Life-Changing for My Sleep!

I’ve struggled with night terrors for a long time, and nothing seemed to help — until I tried the Sleep Now Diffusers by Zenko Health. These diffusers have genuinely transformed my nights. Within a very short time of using them before bed, my night terrors stopped completely, and I’m finally getting restful, peaceful sleep.
The scent is calming without being overpowering, and it creates a really relaxing atmosphere in the bedroom. I’ve tried lots of products over the years, but this is the first one that actually made a dramatic difference.
If you’re someone who struggles with disrupted sleep or night terrors, I highly recommend giving this a go — it’s been an absolute game-changer for me!

Manage subscription seems to be deliberately difficult to find. Not sure how the score is so high with such predatory tactics.

Hello Jamie,

Thank you for your feedback — we take what you've shared to heart.

We want to be completely transparent: Zenko Health does not automatically enrol anyone in a subscription. It’s something customers must manually select at checkout. Once a subscription is activated, we send an email confirmation that includes all the relevant details and a direct link to manage it. You can always find that email again by simply searching “Zenko Health Subscription” in your inbox.

That said, we fully acknowledge your point — accessing the subscription management page should be easier. We’ve taken your comment seriously and made improvements: there's now a dedicated “Manage Subscription” link in the main header of our website and foooter, making it easier than ever to access and manage your subscription directly.

We’re very sorry for any frustration caused and are grateful you raised this. Your feedback is helping us do better.

After years of poor sleep and waking groggy I found this product. It is NOT a vape. It is a diffuser. Use it half an hour before bed and will will slip into a peaceful sleep and wake up refreshed for the day. Give it a try you have nothing to lose except a good night's sleep

Great product that works


I find Sleep Now works really well for me. They help me get to sleep a lot quicker and stay asleep, which is unusual as I normally wake up frequently every night. Also, I don't feel groggy the next day which is important as I am a domiciliary carer.
