Frequently Asked Questions

Product Questions

Why Zero Melatonin?

Melatonin is a hormone found in most traditional sleep supplements that helps with sleep timing. While melatonin can assist some with falling asleep, it does not directly improve sleep quality or duration. Possible downsides include morning grogginess, unpleasant dreaming, dependency, and impacts on other hormones. Due to its limited benefits and potential downsides, we will NEVER include melatonin in our formulation. Dr. Andrew Huberman discusses this at length on his podcast, Huberman Lab, especially in the first few episodes.​

What's in it To Help Help Me Sleep?

For a supplement to help with sleep, it needs to do TWO key things:

1. Help you relax and counteract overstimulation.

2. Support your brain chemistry and hormones for Deep and REM sleep.​

Thirdzy contains some of the best natural compounds to help with BOTH.

Collagen: The Relaxing Power of Glycine
Collagen is rich in glycine, an amino acid known for its calming effects on the brain. Glycine acts as an inhibitory neurotransmitter, reducing nerve activity and promoting relaxation. Studies have shown glycine can lower core body temperature, important for deep sleep, and reduce next-day fatigue.

L-Theanine: Unwind and De-stress
L-Theanine, a compound found in green tea, has been widely studied for its ability to counteract overstimulation, promote relaxation, and reduce anxiety. It increases alpha brain waves, associated with relaxation and REM sleep.

GABA: A Neurotransmitter for Tranquility
Gamma-Aminobutyric Acid (GABA) is a neurotransmitter that promotes relaxation and sleep by inhibiting nerve activity in the brain, helping to quiet the mind for deep, uninterrupted sleep.

Magnesium: The Mineral for Relaxation
Magnesium is an essential mineral involved in over 300 biochemical reactions in the body. It plays a significant role in muscle relaxation and the regulation of the sleep-wake cycle by supporting your natural production of melatonin.​

How Should I Take My Thirdzy?

For best results, take it 30-60 minutes before bed. Experiment with the amount of water you use; more water will mellow the flavor and help it dissolve more quickly. Thirdzy is formulated for nightly use, and consistent users often see the greatest improvements in sleep quality.​

I have definitely noticed a difference in time to fall asleep, as well as maintaining sleep. Still having some issues but it has gotten better. I can tell when I happen to not take it. I have been on Thirdzy for about 1 month and will continue to use this excellent product!

Thank you for sticking with it—we’re honored to be part of your sleep journey, and we’re excited to be part of all your sweet Thirdzy dreams! ✨

Improved deep sleep

Been taking thirdzy for about a month now, and my deep sleep has improved by a noticeable margin. It’s definitely part of my sleep preparation routine now. Pretty convenient to have everything you need in one product. It also tastes great!

We love hearing that Thirdzy has earned a permanent spot in your nightly routine. When your deep sleep levels start climbing and it’s all packed into one convenient (and tasty) scoop—that’s when you know it’s working.

Here’s to more nights of solid recovery and sweet dreams ahead!

BEST SLEEP EVER!!!!

As an avid melatonin user I was taking 12mg a night and still having issues falling asleep. I bought Thirdzy because they offered the free trial. After a few days of Thirdzy's I had complete cut out melatonin and feel so much better! I fall asleep as soon as I shut my eyes and have no problems waking up now. I would should my praises from a rooftop if I could! I've reccomened Thirdzy's to everybody I talk to. We don't even have to be talking about sleep and I'll bring it up. Everyone that has any issue falling asleep should buy Thirdzy's right now!

We have now opened the doors for you. ✨ As the newest member of the Anti-Melatonin Club, welcome—we’re thrilled to have you here!

The lie we all believed for so long? That melatonin was the only way. LIESSSS. And now? You’re proof that there’s a better way. Falling asleep the moment you shut your eyes, waking up refreshed, and feeling like a brand-new human? That’s the dream… and now you’re living it.

Sleep is a luxury these days, but guess what? Welcome to Dream Town. Population: Well-Rested Only. 😴🔥

Sleep tight,
