Traditional sleep aids such as diphenhydramine (zzzQuil, Benadryl, etc.) only make you drowsy. They do not promote restorative sleep. Cosmo combines a unique formula of natural ingredients to not only help you fall asleep, but also make it easier for your body to get restorative deep sleep. 

Cosmo is designed to improve the quality of your rest night-after-night. 

We’re currently conducted a closed beta test of Cosmo and finalizing our formula based on user feedback. We will announce preorders and pricing, which will be reasonable, soon. 

You will be able to order Cosmo as a subscription or one-time purchase.

Cosmo is worth trying even if you have no issues falling asleep. It can help you fall asleep faster and promotes deep sleep.

Even if you can’t get the recommended 7-8 hour of sleep each night, it’s great to make the most of the sleep time you have.

Think of Cosmo as both a sleep enhancer and sleep aid. 

Cosmo uses a Size 0 pill capsule, which is smaller than many pills on the market. We think it’s pretty easy to swallow.

You can also open Cosmo capsules and swallow the powder directly, or mix the powder in water or tea. It’s up to you!


Cosmo contains only natural ingredients well-researched to improve sleep and sustainably sourced.

Each serving of Cosmo (one pill) contains the following:

Melatonin: 3 mg

L-theanine: 150mg

Magnesium: 150mg

Our pill capsules are made of hypromellose, a vegetarian alternative to gelatin composed of plant fibers and water.

Yes! It'a also gluten and allergen-free. 

Cosmo should be taken 30-60 minutes before bed. Some people may notice the effects faster. 

We want you to be able to fall asleep quickly but be able to wake up quickly and enjoy your day.  Cosmo has just enough ingredients to put you to sleep but not so much that you have trouble waking up the next day. 

Cosmo is non-habit-forming.
