What Our Athletes Say About Using Rest & Recover Collagen

Sleep is the foundation of recovery. Without it, energy dips, soreness lingers, and progress stalls. That’s why so many athletes have made Thirdzy’s Rest & Recover Collagen part of their nightly routine.

We asked our community what’s changed since they started using Thirdzy magnesium powder before bed. Here are the five themes that come up again and again.

A common complaint with melatonin and other sleep aids is waking up foggy. Thirdzy is different — it’s a melatonin free sleep aid, so you get the sleep support without the hangover.

• “I have tried so many things and they all would leave me feeling groggy the next day. This product being melatonin free has allowed me to have the best sleep, while feeling energized and able to take on another day.”

• “It is the BEST sleep aid I have ever used. Gets me to sleep and keeps me asleep.”

• “I work shift work and long hours. This is the BEST product I have ever used!”

• “Bedtime routine is the best it has ever been. No other product is as good or as easy as Thirdzy!”

Whether it’s falling asleep faster, staying asleep through the night, or simply sleeping longer, athletes consistently report that Thirdzy actually works when it comes to boosting their sleep and muscle recovery.

• “First time I’ve fallen asleep and stayed asleep in years!”

• “I struggle to sleep more than 5 hours but just after a few consistent days taking Thirdzy I’m sleeping through to my alarm.”

• “I've never been a good sleeper. Within a few days of taking Thirdzy I was staying asleep better and waking more rested.”

• “My mind has been racing lately and even with that I am noticing by the time I get into bed I am able to calm down and fall asleep quicker.”

• “I find that even if I wake up, it is easier to fall back to sleep.”

Thirdzy’s collagen sleep aid isn’t just about sleep — it’s about what that sleep unlocks. With deeper, more restorative rest, athletes feel less soreness, recover faster, and train harder with fewer setbacks.

• “I am incredibly impressed with the absence of soreness from training, the ease with which I can go to sleep and remain asleep. I feel alert on waking up and my training aches and soreness have all but disappeared most days.”

• “I always struggled getting to the gym in the morning, but now taking Thirdzy before bed I wake up feeling ready to go!”

• “I work hard, I workout hard, so I better recover well to make improvements. This has been a game changer in how I wake up.”

• “My recovery and training have never felt better, and injuries no where to be found.”

It’s not just how athletes feel — their devices confirm it. From Whoop to Oura to Garmin (wearables that can track your sleep, fitness, and health metrics), the data reflects what users are experiencing: more deep sleep, more REM, higher HRV, and better recovery scores.

• “I'm falling asleep faster, waking up less, and my recovery scores on my Garmin are soaring.”

• “My Whoop tells me I'm already sleeping 32% more than a week ago.”

• “My REM has more than doubled! Excellent product.”

• “I've gotten way more deep sleep according to my Whoop.”

• “Since I started with Thirdzy, my REM and Deep sleep have increased and my HRV has improved.”

The ultimate test of a sleep supplement or sleep stack is how you feel in the morning. Thirdzy users report waking refreshed, energized, and ready for the day — without the grogginess that comes with other sleep aids.

• “MAJOR difference in sleep quality. I stopped waking up tired and instead feeling energized and ready to start the day!”

• “Love how it had me feeling energized the next day!”

• “Deeper sleep without the groggy feeling when you wake up. Exactly what I was looking for with a nighttime supplement.”

• “It’s night and day. When I sleep with Thirdzy, I feel like a new person in the morning.”

• “Best night sleep ever! Fall asleep fast, stay asleep and don’t wake up groggy.”

• “It helps me wind down quicker, sleep deeper, and wake up feeling less sore and more refreshed.”

From better sleep quality to stronger athletic recovery and improved training metrics, athletes keep coming back to the same conclusion: Thirdzy works. It’s melatonin-free, athlete-formulated, and proven — both in how people feel and in the data they track.

If you want deeper sleep, faster recovery, and mornings where you wake up ready to go, it may be time to make Thirdzy part of your routine.
