Yin Sleep Reviews

3.6

Yin Sleep earns mixed-to-positive reviews: many users report faster sleep onset, deeper REM and deep sleep, and clearer mornings, while others see no improvement or even worsened metrics and vivid or anxious dreams. Reviews praise all‑natural ingredients, easy capsules, and tasteful, travel‑friendly packaging, but note inconsistent efficacy, three‑capsule dosing, bitter flavor for some, and occasional grogginess or nausea.

    I took this for two days and my sleep was significantly worse based on my Oura ring, dropping to a 59 sleep score. I had very vivid dreams and notably worse REM and Deep Sleep. Right after I stopped taking it my score went back to 89. In better news, I was so wired the next day. I deep cleaned my fridge, labeled all my stored food with chefs tape and organized by date. I also walked 2 miles to buy tortillas for no reason. It was a very productive morning. I really enjoy the product for this specific effect. I let a friend try and she also took it for two nights and had intermittent waking.

    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.
