We Back it Up With the Actual Studies & What it Means for Your Sleep & Recovery
INGREDIENTS CLINICALLY SHOWN IN OVER 21 STUDIES TO help you recover faster while you sleep
Formulated by in-house researchers to contain clinically effective doses of only the most research-backed recovery and sleep ingredients. No bullsh** patented formulas or harsh sedatives. 35+ clinicians and health professionals confidently recommend MAS Overnight Recovery.
Glycine
Glycine is an amino acid that acts as a calming signal in your brain and spinal cord. At the same 3 g dose in MAS Overnight Recovery, people fell asleep faster and reached deep sleep 26 minutes sooner, measured in a sleep lab [1].
Glycine also makes up about one third of collagen, the protein your tendons and ligaments are built from, so a nightly dose supplies more of the raw material your body repairs them with [2].
Research shows that supplementation with glycine . . .
- Shortens the time it takes to fall asleep [1]
- Gets you into deep sleep sooner, which is when your body releases most of its growth hormone [1,3]
- Reduces next-day fatigue after a short night of sleep [4]
Montmorency Tart Cherry
Montmorency tart cherries are rich in anthocyanins, antioxidants that lower inflammation after hard training [1].
In a study of marathon runners, leg strength was back to its pre-race level 48 hours after the race with tart cherry. The placebo group was still 9% weaker [1].
Research shows that supplementation with tart cherry . . .
- Speeds up the recovery of leg strength after a marathon [1]
- Lowers markers of inflammation after long, hard runs [1]
- Increases total sleep time [2]
Magnesium (as Magnesium Bisglycinate Chelate)
Magnesium helps your muscles relax and your nervous system settle down at night. You also lose magnesium in sweat, and hard training may raise how much you need by 10 to 20% [1].
Research shows that supplementation with magnesium . . .
- Reduces the time it takes to fall asleep [2]
- Increases sleep efficiency, the share of your time in bed spent asleep, from 67% to 73% [3]
- Replaces the magnesium you lose in sweat during high-mileage training [1]
KSM-66 Ashwagandha
Ashwagandha is an herb that lowers cortisol, your body’s main stress hormone. Cortisol rises after hard runs, and in one study it climbed 44% within an hour of finishing a half marathon [1].
Keeping cortisol in check helps you handle training stress and life stress in the same week.
Research shows that supplementation with ashwagandha . . .
- Lowers cortisol by 16% in 8 weeks [2]
- Improves self-rated sleep quality by 35% [2]
L-theanine
L-theanine is an amino acid found primarily in tea that helps balance the levels of two chemicals in the brain known as glutamate and GABA, which transmit nerve impulses.
This, in turn, can reduce anxiety and promote relaxation without causing drowsiness, which helps you switch off after an evening run or a stressful day.
Research shows that supplementation with L-theanine . . .
- Reduces the time it takes to fall asleep [1]
- Improves restfulness after sleep [2]
- Supports relaxation [3]
- Reduces the effects of mental stress [4]
Saffron (affron®)
affron is a standardized saffron extract studied for sleep and mood. MAS Overnight Recovery uses 30 mg, just above the 28 mg dose tested in the research.
Research shows that supplementation with affron . . .
- Reduces insomnia symptoms by 25% in 4 weeks [1]
- Helps you wake up feeling more restored [1]
- Improves your mood after waking [2]
Tryptophan
Tryptophan is an essential amino acid your body uses to make serotonin and then melatonin, the hormone that signals it’s time to sleep. It gives your body the building block to make its own melatonin, so MAS Overnight Recovery has no added melatonin.
- In a sleep-lab study, a low dose of tryptophan (250 mg) increased the deepest stage of sleep [1]

Made in USAYour Training Deserves Better Sleep and Recovery
Every run and hard workout produces small amounts of damage in your leg muscles, which creates inflammation. This inflammation is what makes your legs feel weak and heavy for the next day or two.
The tart cherry in Overnight Recovery is rich in anthocyanins, which are antioxidants that calm that inflammatory response. Reducing inflammation…
- shields the healthy surrounding tissue from collateral damage so there is physically less muscle to rebuild
- helps restore normal blood flow so more oxygen and nutrients make it to your muscles to help them repair
The result is that your legs regain their strength sooner and you start your next hard session fresher.
Most of your physical recovery happens in deep sleep, and your body only gets there once your nervous system settles down.
Glycine acts as a calming signal in your brain and spinal cord, while magnesium and L-theanine quiet the nerve activity that keeps you awake.
You fall asleep faster and reach deep sleep sooner, which leaves more of the night for recovery.
A hard run switches your nervous system into “fight or flight” mode and raises cortisol, a stress hormone that breaks down muscle protein.
Your body does most of its repair after it shifts back into “rest and digest” mode. It can’t do this when cortisol levels remain elevated.
Ashwagandha lowers cortisol, and magnesium and L-theanine calm your nervous system at night, so you switch into recovery mode sooner, absorb more of your training and sleep more deeply.
Tendons have a poor blood supply, so they repair far more slowly than muscle and are often the last part of your body to adapt when your mileage goes up.
Tendons are made mostly of collagen, and glycine makes up about one third of collagen. Clinical research shows that supplementing with glycine…
- Doubles your collagen synthesis rate to trigger faster tendon repair directly at the injury site.
- Increases tendon stiffness, which manually overrides poor blood supply to shield your Achilles from the painful micro-tears that cause chronic tendinitis.
Short nights and heavy training both drag down your mood, and a bad mood makes it harder to get out the door for your next workout.
Overnight Recovery provides 200mg of tryptophan, the amino acid your body uses to make serotonin and melatonin. Tart cherry also slows the breakdown of tryptophan so you get the full benefits.
Overnight Recovery also includes saffron, which supports serotonin, the brain chemical that keeps your mood steady, and ashwagandha lowers cortisol, so you start the day less stressed.
All of this means you sleep better and because there’s no added melatonin, you wake up clear-headed instead of groggy and ready for your morning run.
Growth hormone supports the repair of muscle, tendon and bone and 70% of the growth hormone pulses released when sleeping happen during deep sleep.
After the age of 36, deep sleep accounts for just 3% of total sleep. Glycine helps you reach deep sleep sooner, so the first and largest release of growth hormone comes earlier in the night, supporting long-term growth hormone production.
is Overnight Recovery only for those that have trouble sleeping?
Even if you don’t have trouble falling asleep, increasing quality time spent in deep sleep can have a huge impact on your overall health. Plus Overnight Recovery was built for more than just getting to sleep faster.
Here’s how Overnight Recovery can help you…
- Take Before Bed
Enter Deep Sleep Sooner and Stay in it Longer
Your body relaxes and winds down at bedtime, so less of the night goes to tossing and turning. More of it goes to deep sleep, when your body releases most of its growth hormone to repair the muscle you broke down in training.
- The next morning
Wake up with fresher legs
Your legs feel less heavy on the first steps out of bed, and the easy run after a hard day feels like an easy run again. Plus, no added melatonin means you wake up refreshed and without the typical grogginess you get with other sleep supplements.
- The first few weeks
Bounce back faster from hard workouts
The soreness from long runs and workouts fades sooner, so you’re ready for your next hard session on schedule instead of pushing it back a day. Over a full training block, that adds up to more quality workouts completed.
- By Week 8
Handle heavy training better
Big training weeks take less out of you. You sleep soundly through your highest-mileage weeks, feel less run down, and have more energy left for the workouts late in a training block.
I've been taking Overnight Recovery for a few months now. It's my favorite part of winding down for the night! Definitely has played a big part in my sleep and recovery! My energy during my training sessions has improved just due to the increased amount of sleep that I have been able to get.
Mark Hampton⭐⭐⭐⭐⭐
I track my sleep with Whoop. In the past month, the amount of sleep I have gotten has decreased due to work, but there is a NOTICEABLE difference when I take Overnight compared to when I don't. This has really helped me grind through this busy time at work.
Samantha T⭐⭐⭐⭐⭐
I'm pretty skeptical about sleep supplements, but I tried this one on a recommendation from an influencer and because it had no melatonin. I've noticed a huge difference in how relaxed I feel before bed and I feel like I've seen a noticeable difference in how fresh I feel for workouts, especially my strength training.
Marcela⭐⭐⭐⭐⭐
After my last ultra, I felt like I wasn't recovering as quickly as I used to. My coach mentioned it might be sleep so I decided to try Overnight Recovery. It made a huge difference the first week and I thought it might just be a placebo but it's lasted the entire month. I am really happy to have found something I can take every day!
Thomas Lafortune⭐⭐⭐⭐⭐
I switched to Overnight after using a sleep matcha drink. I still use the matcha in the winter when I want something warm before bed, but I like the ease of pills and it's made my sleep much more consistent this training cycle.

No grogginess
I purchased this to help me stop taking melatonin and improve my sleep quality. I’ve stopped taking melatonin and haven’t had trouble sleeping which is wonderful! I don’t use a tracker that would show if sleep quality has improved, but I’m glad to be using something that doesn’t leave me groggy the next day. The first dose or two I had a bit of heartburn, but taking it with more water and sitting upright a bit longer thankfully helped prevent that problem.

Great improvement in sleep scores
I was a little skeptical that this would do anything, so I was keen to check out the data to see if it actually worked. To my surprise, the results were pretty dramatic after only a few days. I’ve continued to take and my scores are definitely consistently higher than they were this time last year.

faq
Will Overnight Recovery work for me?
The ingredients in Overnight Recovery are backed by more than 21 peer-reviewed studies to improve sleep quality, duration, and recovery so it should work for anyone who wants to improve their sleep.
That said, Overnight Recovery is particularly effective for those that consistently struggle with falling asleep or waking throughout the night.
Can I take it every night?
Yes! Because Overnight Recovery contains no heavy sedatives or habit-forming ingredients like added melatonin, it is safe to take every night.
How much and when should I take?
Mix one scoop of Overnight Recovery in water and drink it before bed. Within a few minutes you can expect to start feeling calm, relaxed and ready to go to sleep when you want to.
Is Overnight Recovery 3rd Party Tested?
The main ingredients in all of our products are tested for heavy metals by a 3rd party lab. All other tests are performed in our US-based manufacturing facility using equipment and processes that comply with FDA GMP standards.
Why is there no added melatonin?
While melatonin is safe, many sleep experts believe consistent supplementation can cause your body to lower and eventually stop its own natural melatonin production.
That means you need to take more and more melatonin for it to work and eventually it stops working.
Leaving out added melatonin means you can use Overnight Recovery nightly and wake up without any morning grogginess or impact on long-term health.

Do you not ship to my country?
Unfortunately, we can’t ship to some countries because they’re very strict on what supplements they will and won’t allow to cross their borders, and too many customers were losing their orders.
