  • Induces solid sleep
  • Waking up refreshed
  • Easy to swallow capsules
  • Fast shipping
  • High cost
  • Large dosage required
  • Inconsistent results
  • Possible negative side effects

Yin Sleep is generally appreciated for its ability to induce solid and restful sleep, with users reporting that they wake up feeling refreshed and not groggy. However, the high cost and the large dosage (3 sizable capsules) are highlighted as downsides. Some users didn't notice a significant difference in their sleep patterns, and a few reported negative side effects such as nightmares, headaches, and feeling groggy in the morning.

  • Coming from a science background I'm doubtful of most nootropics, so I admit I tried these with a healthy dose of skepticism. In the end, however, I was pleasantly surprised. The manufacturer is still dialing in the exact formula (I wrote the founder to find out more about the various ingredients), yet over the course of my seven-day trial I found this dosage to be quite effective. I had a deeper, sounder sleep five of the nights I used them, and had no negative physical or psychological reactions. And, since they impact REM sleep, I awoke most mornings having better recall of my dreams than usual, which I found telling. The primary ingredients are L-Theanine and magnesium, with other proprietary components like NanoHemp, NanoCBN, and an exclusive blend of eight terpenes labeled YinTerpene, though, other than possibly the terpenes, I don't know if these unique elements are of high-enough quantity to have a significant effect in and of themselves. That having been said, it worked for me, at least for a week. I'm not sure if it will retain the effectiveness over the long term, but I'm certainly going to give it a go for another month or so.

  • I got to test a 7 day pack and after the 3rd night I ordered the full bottle. I love using these to go to sleep. They’re not drowsy nor addictive. I’ve been getting a great night sleep with these. Worth the try!

  • I like the ingredients and the concept behind the sleep formula. No melatonin which gives me headaches. Contains magnesium which is lacking in many diets and so good for us. Three fairly sizable capsules is the dosage, which seems like a lot, but with a few good chugs of water, they go down fine. Upon my first night's trial, I was able to fall asleep within the hour and woke 5 hours later. This is how ambien affects me as well. So if ambien works for you, there’s a good chance this will work for you. I had. I experienced no negative side effects, so I’m going to finish out the trial pack and see if that 5 hour sleep will increase.

  • I loved it! I've tried a handful of sleep supplements in the past because it's been expensive, I woke up groggy, or it had ingredients I don't want to be ingesting nightly (looking at you, melatonin). But with Yin Sleep, I felt like I fell asleep quickly and peacefully. No sudden "I need to be in bed right now, or I will be on the couch all night feeling. " I usually only sleep 7 hours, and I had a few nights of trying it out that I probably slept even less but never woke up sleepy! I will definitely be back to purchase more. Shipping was fast too! So that's a nice touch.

    super glad to hear it's working well for you garrett. that lack of sedation you're describing is a critical aspect we focused on - we wanted something that optimize sleep quality while you're asleep rather than knocking you out. appreciate the review! - Ali

  • Not a huge fan! I tried taking this and I didn't have a greatest experience. I had such a weird sleep, and my REM significantly dropped. I currently use WHOOP to track my sleep. I woke up with a headache and really low recovery. Also I understand that this has Nanohemp in it, so that could be the thing. My body doesn't react to hemp really well, so that could be it too. But overall, I am going to take a pass on this.

    man, really sorry to hear this! from all our beta testing, there's a rare few (less than 5% of people) that have an adverse effect with the formula. as you suspected, it's likely the Hemp that doesn't jive well with your body. for most people that's the most impactful ingredient on improving sleep quality, but all bodies are different. we tried to make this the most accessible formula, with the least contraindications (which is why we avoided melatonin, ashwagandha, 5htp), but it will never work for 100% of people. we may release a hemp-free formula in the future, but probably a year or two out from that. appreciate you giving it a shot - sorry it didn't work out well for you. - Ali

  • My daughter is finally sleeping through the night, but I noticed my sleep quality has been very poor. I can't fall asleep, I wait up in the middle of the night, and even when I have a full night of sleep, I wake up feeling groggy. I wanted to try Yin Sleep to see if it would help me feel more rested. It's honestly difficult to say after a 7-day trial pack. Perhaps a 14-day trial might be more helpful in assessing the effectiveness. Normally, within a week, I have about half days of good sleep and half the days are more difficult (issues falling and/or staying asleep). With the 7-day trial pack, it ended up being about the same in terms of sleep quality. So that didn't change at all. Perhaps the biggest thing I noticed was that when I did sleep well, I woke up feeling more rested and less groggy than I normally have. The price point is a challenge. With all the vitamins and supplements out there, I'm not certain if this one would be a "must have", especially if it's not producing amazing results. But I am curious and would be interested in trying for a bit longer just to see. I'll report back! Another positive, though, was GREAT customer service!

  • I do feel like this helped me fall asleep faster and stay asleep overnight. I often have trouble falling asleep and staying asleep, and noticed it was easier to fall asleep and I didn't feel like I was waking up as much. It's not a sudden effect like a prescription medication would be, but does feel like it's doing something. The format is a little annoying - it's three large pills per evening, which is quite a lot. I'm not super good at remembering to take pills, and even when I do the large dose is enough to sometimes put me off, so I wasn't able to consistently take these every night for 7 days as recommended. But on the days I did take them, I do feel like they helped.

    appreciate the insight here alexandra - definitely agree that capsules isn't the most ideal form factor at night, but we decided on it for a couple reasons: 1) we found it was the simplest thing for the majority of people from beta testing. some of the ingredients have a strong flavor, which creates its own complications when trying to create a flavor profile for a tincture or gummies. it's also really easy to travel with. 2) it's more time released in a capsule. for impacting sleep quality throughout the night, this is important. a tincture is more likely to exert an effect quickly, and fade more quickly. appreciate you testing out the product & leaving a review! glad it did help for the days you used them. - Ali

  • This stuff is pricey, but I did the seven day trial and I felt like my sleep really did improve during that week. I felt more rested waking up, and it just felt like I slept "harder." I'm not sure if I can afford to keep purchasing it regularly because of the amount of other supplements I take, but I think this stuff is great!

  • so i'll preface this with the fact that i have never tried any sleep aids (ie magnesium citrate) and was going into this experience blind. after trying it for a week, i don't think it affected me in the slightest. i monitored my sleep before, during, and after for a week each and there was no noticeable change. i will say i was very good about adhering to their rules - no bright led/blue light 30 minutes before bed, having quiet time for at least an hour, yoga/meditating/stretching, etc - and i feel like that alone helped me sleep better.

  • So, I gave the Yin Sleep formula a go, hoping it’d help with my insomnia. To be honest, it didn’t do much for me, but my sleep issues are pretty hardcore, so maybe I’m not the best test case. What I loved: The ingredients are solid, and it’s nice knowing it’s all-natural. The capsules are easy to take and didn't upset my stomach. What needs improvement: Wish it had more of a punch. Maybe stronger dosages or a different mix for folks like me with serious sleep problems. Overall, it’s decent compared to other sleep aids out there, but my results might be skewed. Give it a try if your sleep troubles aren’t as extreme as mine. 🌜

  • These pills actually work but they just happen to not agree with me. Upon taking my first dose I noticed intense effects, sometimes things like this you feel nothing at all, that was not the case for me here. I am very sensitive to sleep medicines especially melatonin so I thought this would be good to try. For me it was even more intense, so I won't be continuing on it, but I appreciate that I could try it without the full commitment. I have a friend with sleep issues who takes a lot of melatonin and sleep gummies for insomnia who I will be gifting this to, but it was too much for me who thought it would be nice to have when I have occasional jet lag and/or stress related sleep issues.

  • To be honest, it is hard to say if there was a noticeable change in my sleep patterns.

    sorry to hear it didn't help! happy to chat via email and recommend some other solutions that might push the needle for you, depending on what aspect of your sleep patterns need addressing! [email protected]

  • Unsure of the effects of Yin Sleep as I do not have any technologies tracking my sleep but based off my ability to fall asleep quicker, I'd say Yin Sleep does it's job. As for increasing deep sleep amounts, I've woken up the following day about the same as usual. Overall, I'd say try Yin Sleep and track your sleep to see if it actually works for you!

  • I liked the branding and packaging but I didn’t notice any difference when taking them. I also wear a sleep tracker and it didnt pick up an increase in deep sleep

  • At $22 for a week, it's too expensive for me. While Yin helped, it wasn't worth the cost. As it did not help that much to pay so much.

  • The package came quickly and the seller was very helpful checking how the product was. I had nightmares the first time and next time made me anxious. I haven’t tried it again after that. But can update it later

  • I suffer from night-time anxiety which causes me to feel restless and unable to sleep until 1 or 2 AM. I've tried everything non-prescription, including various supplements and nothing works for me. Hence, why 1. I was curious about this product, and 2. I have a high bar for success. Unfortunately, this just didn't do anything to improve my insomnia in the nights I took it. In fact, I kind of felt more "alert" which tends to be the case when I take CBD (calm but focused, not sleepy). Still gave it a 2 out 5, because branding is nice and perhaps this will have a different effect for someone else....just not for me. Another thing to consider, is that you have to take 3 pills. I'm sorry, but that's a lot. There are gummies out there. Even if this worked, it's kind of a hassle.
