Magnesium is the single best “sleep supplement” you can use. It’s supported by countless research studies and impacts sleep, performance, and recovery on multiple levels.
Moreover, studies suggest that 75% of endurance athletes are deficient in magnesium, so it is likely a mineral you need to supplement with regardless if you need to improve your sleep or not.
Ashwagandha is known for its stress-reducing properties, and stress and anxiety are common culprits behind sleep disturbances. By calming the nervous system, ashwagandha may indirectly promote better sleep.
Some studies suggest that ashwagandha can lead to improvements in sleep parameters like sleep onset latency (the time it takes to fall asleep), total sleep time, and sleep efficiency (the ratio of time spent sleeping to time spent in bed).
Research indicates that ashwagandha may help reduce the number of times people wake up during the night.
Valerest is a proprietary blend of natural ingredients, including valerian root, designed to promote sleep and relaxation.
Results from multiple studies indicate that valerian — a tall, flowering grassland plant — may reduce the amount of time it takes to fall asleep and help you sleep better.
Specifically, a systematic review of 16 randomized controlled trials found that valerian improved sleep quality in 80% of trials [1]
In a meta-analysis of 18 studies valerian showed a statistically significant benefit compared to placebo [2] and in a study of 128 patients, 44% reported perfect sleep and 89% reported improved sleep after valerian [3]
Gamma aminobutyric acid (GABA) is a neurotransmitter that binds to receptors between neurons and reduces their tendency to “fire” and transmit nerve impulses.
This, in turn, can reduce stress and excitement and promote calm and restfulness, which is why research shows that supplementation with GABA . . .
May reduce the time it takes to fall asleep [1,2,3]
Improves the perceived quality of sleep [4,5]
Increases sleep efficiency [6]
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 is why research shows that supplementation with L-theanine . . .
Tryptophan is an essential amino acid and a precursor to serotonin and melatonin, both of which are crucial in sleep regulation. But, unlike melatonin, tryptophan does not impair REM sleep or cause dependency.

Research on our ingredients has shown deeper sleep leads to faster and more efficient recovery so you can absorb all of your hard training.
Clinically data and our customer feedback show significant increases to their sleep scores with most averaging 90% + per night.
No melatonin means you wake up refreshed and without the typical grogginess you get with other sleep supplements.

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 MAS Sleep. 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!
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.
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 MAS Sleep compared to when I don’t. This has really helped me grind through this busy time at work.
I’ve been taking MAS Sleep 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.
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.
The ingredients in MAS Sleep 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, MAS Sleep is particularly effective for those that consistently struggle with falling asleep or waking throughout the night.
Yes! Because MAS Sleep contains no heavy sedatives or habit-forming ingredients like melatonin, it is safe to take every night.
Take 2 capsules of MAS Sleep about 30-60 minutes before bed. Within a few minutes you can expect to start feeling calm, relaxed and ready to go to sleep when you want to.
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.
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.
The omission of melatonin means you can use MAS Sleep nightly and wake up without any morning grogginess or impact on long-term health.
