Why we’re so obsessed with sleep

At Cosmo, we genuinely believe sleep is the secret weapon of success. Better sleep not only improves cognitive and physical performance, but also improves overall health and well-being.

Not all sleep is created equal. Cosmo’s ingredients specifically target the deepest stages of sleep to help you get the most out of each night.

Frequently asked questions

We’ve seen these so many times,

they put us to sleep.

How is Cosmo different from other sleep aids?

Traditional sleep aids only make you drowsy– they don’t promote the deep stages of sleep that leave us feeling restored and refreshed.

Cosmo works with your circadian rhythm to naturally promote deeper sleep. It’s an easy way to get better sleep each night.

Will I feel groggy in the morning?

We firmly believe hangovers are for drinking, not sleeping. We designed Cosmo so that it wears off well before the morning so you can conquer the day ahead.

You’ll wake up feeling alive, awake, alert and (hopefully) enthusiastic after taking Cosmo.

Can I return Cosmo if I'm not satisfied?

We want you to be happy with Cosmo and enjoy a better night’s sleep. If for any reason you are unhappy with Cosmo, you are welcome to return it within 30 days of delivery for a full refund. We’ll even cover the return shipping!

Is Cosmo habit-forming? Can I take it every night?

You might get “hooked” on a good night’s sleep, but that’s about it. Cosmo is designed to be taken nightly and is completely non-habit-forming. Cosmo is not a drug. You might get used to its effects, but it is not possible to develop a “tolerance.”

When I should I take Cosmo?

We recommend taking Cosmo 20-30 minutes before bed. You may notice the effects sooner or later depending on a variety of personal factors. Experiment and see what works best! 

We’ve heard Cosmo best described as a “nice gentle pull, but not a push.” You can expect to feel relaxed and ready for bed. You’ll probably yawn, too. But you won’t feel artificially knocked out.
