I bought this product because I’m going to be traveling next month to run marathons and half marathons, and was seeking a sleeping aid that would help me get restorative deep sleep (as opposed to a NyQuil which makes me feel hungover). I decided to test this out, as my races are 1 and 4 weeks out respectively (don’t want to try something new on race day!). Qualitatively, I slept like a freaking baby! I typically wake up 1-3 times throughout the night, which severely hinders my deep sleep—which is particularly important for recovery— but with Yawn, I didn’t wake up throughout the night. This was a huge game changer. I also get refreshed in the morning. I usually fee like haven’t a second cup of coffee around 1 or 2pm, but with The help of Yawn, I didn’t even think about a second cup. Objectively/quantitatively, my Oura ring gave me the hard data: my deep sleep and rem sleep were proportionately and absolutely higher than my averages. While my actual sleep time didn’t increase, I had better QUALITY sleep, which is more important. Only issue is that I did feel some sleep inertia when I initially woke up, but it went away completely within 20 mins (didn’t feel groggy throughout the day at all). Highly recommend!

I was really looking forward to finally trying out a HVMN product but this is not a great first impression. Arrived with pill contents spilled outside of the capsule. Not sure which capsule leaked, for all I know they all could have leaked which means when I take it I am not getting the listed dose which is unacceptable. I order other pills/nootropics from other brands and they never come in looking like this. The capsules even seem to only be filled up to about 80% capacity, which I haven't seen with other pills. [Update 04/16/19] Although I was disappointed with the packaging I must say that these pills are pretty good! For this past week and a half I've taken 1 almost every night before bed and I've noticed considerable effects. If I stay up for more than 20 minutes after taking them I feel my eyes get heavy(never felt this with < 1g meletonin alone). In adding to that I actually feel more rested in the morning. Considering all of these factors I'll bump this rating up from 1 to 3 stars. I wish I could give it a 4 or even 5 stars but the packaging was really sloppy.

So happy that Yawn is now available on Amazon. Prime Shipping too! I’ve been using this product for the past year or so and it’s amazing. Melatonin has been in use for many years since it’s study published in the Journal of American Psychiatry. This product is vastly superior compared to straight Melatonin as it is a combination of supplements shown to be effective in inducing sleep.

Yawn is a natural sleep aid created by HVMN, a company that's dedicated to human optimization, across the cognitive, physical, and metabolic domains. This product contains the ingredients: magnesium glycinate, L-Glycine, L-Theanine, and melatonin. In my opinion, the fact that this product has L-Glycine is what separates it from the rest. Many studies have shown that glycine can increase sleep efficiency, reduces symptoms of insomnia, and improves sleep quality by promoting deeper and more restful sleep.

I have been taking melatonin for years and this is one of the best preparations on the market. There is a great balance of enhancement elements that allows the 1mg of melatonin (the level recommended to avoid your body ceasing to produce it on its own) to work more efficiently. Highly recommend this product.

I love the product packaging and clean label. It's fun to get HVMN products because they clearly pay attention to the details. I use the product if I know I'll need a little extra help falling asleep or if I know I'll need as much rest as possible for the next day. Its not like a drug where I go zombie and do dumb things; instead when I take it I either fall asleep easily and quickly (not abruptly like drugs). I wake up feeling refreshed and ready to attack the day! I use Yawn multiple times a week and have had a wonderful night's sleep every time.
