Our purpose

Help you repair the fundamentals of great sleep at night, so you can be the best version of yourself during the day.

Who would have thought that something as simple as getting a good night’s sleep would feel like such an impossible task?

We believe everyone deserves Proper sleep.

So we created a new sleep wellness company.

One that goes beyond a quick-fix to help you rebuild long-term sleep health.

One that understands that sleep is personal and considers your individual habits and lifestyle.

One that takes a holistic approach by combining high-quality supplements with coaching.

We're probably the only ones obsessing over your sleep as much as you are. But it's because we know how much it matters.

We know that it affects your life outside of the bedroom.

We know that you've tried everything to fix it, and then tried it again.

We know that the sleep industry has let you down, and we know that you're tired.

That's why we're not messing around.

Here's to the end of tossing + turning.

Our Scientific & Medical Advisory Council

Proper's evidence-backed, holistic sleep solution was developed in partnership with leading doctors in integrative sleep medicine, clinical psychology, and nutritional biochemistry.

It's really more about quality of life, and if we are engaging in the things that we value and that gives us purpose, and getting proper sleep really helps bring us in that direction."

"From the beginning, Proper emphasized the need to be science backed, which aligns with my expertise and experience. There are a lot of products on the market that may use clinically studied ingredients, but they may not include the appropriate dose. Proper's ingredients were not only chosen for their clinical studies, but were included at the right dosage to target different aspects of sleep in the sleep cycle."

"I've been in sleep medicine for some time, and I'm skeptical about a lot of supplements. I have a lot of concern about the lack of regulation related to supplements. When I first met with the Proper team, I wanted to see if the product actually works and the evidence behind the ingredients to show that there's a difference between the results versus a placebo effect."
