How to Choose the Right Sleep Support
|
Updated October 2, 2026
We all know just how important sleep is to our health, fitness, and performance. And many of us also know how debilitating poor sleep can be. Navigating sleep supplements can feel overwhelming, with scores of products making competing claims and empty promises. It’s no wonder so many people are left anxious, confused—and still tired.
At Momentous, we believe better sleep shouldn’t be a mystery—or a risk. That’s why we created a curated lineup of science-backed sleep solutions, developed with world-leading experts, rigorously third-party tested, and built to The Momentous Standard®. Whether you’re struggling to fall asleep, stay asleep, settle a restless body, or calm a busy brain, there are safe, effective products made for your needs—no guesswork required.
Why Sleep Matters for Performance for Life™
We talk a lot about Performance for Life™—our belief that real performance is about showing up, consistently, at every stage of life. Sleep is one of the five levers that makes that possible. Without enough deep, high-quality sleep, you can’t recover, adapt, or thrive. No amount of clean eating or exercise will get you the results you want if your body is missing this biological necessity—the one that amplifies every other system: muscle repair, hormone balance, immune strength, brain health, and mood.
So if you're going to invest in supplements to support your sleep, they need to work—not just knock you out, but help your body do what it’s designed to do: recover, repair, and rebuild.
Let’s explore the Momentous sleep lineup so you can choose the product that fits your goals—and your life. Whether you need nightly support, a travel reset, or help quieting a wired mind, the right solution is here—and it’s backed by science, not shortcuts.
Nightly Sleep
A precisely dosed protocol to help optimize your nightly rest.
What It Is:
Momentous Nightly Sleep is a non-habit forming combination of science-backed ingredients shown to promote deep, restful sleep. With Magnesium Bisglycinate, L-Theanine, and Apigenin, Nightly Sleep works on both sides of the sleep equation—settling the body and quieting the mind—to help you fall asleep faster, stay asleep longer, and wake up with renewed vigor to take on the day.
Because it does not contain melatonin or sedatives, Nightly Sleep is suitable—and even recommended—for nightly use, helping you align with your body’s natural sleep-wake cycle for restorative nights that lead to more successful days.
It comes in a 30-serving jar and convenient, single-serve pouches to ensure uninterrupted sleep, and unstoppable performance, are always within reach.
Why It Works:
Instead of relying on a single compound, Nightly Sleep uses a synergistic approach:
Magnesium Bisglycinate is magnesium chelated with glycine—a highly absorbable form that supports the nervous system’s shift out of “always on,” easing the physical tension that keeps the body wired at bedtime.
L-Theanine promotes relaxation by increasing alpha brain waves and supporting GABA, serotonin, and dopamine signaling.
Apigenin reduces neuronal excitability and cortisol, helping transition your body into a calm, sleep-ready state.
Together, these ingredients support relaxation, reduce nighttime wakeups, and enhance sleep quality—without dependency or next-day grogginess.
Who It’s For:
For anyone looking to improve their sleep routine and sleep quality.
When to Use It:
Use nightly, 30-60 minutes before bedtime, as part of your wind-down routine.
Magnesium Bisglycinate
The foundational magnesium for calm and sleep.
What It Is:
Magnesium Bisglycinate is magnesium bound to glycine, an amino acid that makes the mineral easier for your body to absorb and use. One serving delivers 200mg of elemental magnesium—48% of your Daily Value—in a single-form, NSF Certified for Sport® formula with no unnecessary additives.
Why It Works:
Magnesium is involved in more than 300 processes in the body, and it's the foundation that makes physical calm and restorative sleep possible. But not every form of magnesium behaves the same way. Chelating magnesium with glycine improves how much of it your body actually absorbs, and it tends to sit more comfortably in the digestive system.
Glycine also supports GABA signaling, the pathway your nervous system uses to downshift. That combination is why bisglycinate is the go-to form for sleep and calm: it helps ease the restless, wired-in-the-body feeling—tense muscles, twitchy legs—that can keep you awake even when your mind is ready to switch off.
Who It's For:
Anyone looking to improve their sleep and feelings of calm and relaxation. It's also a straightforward way to close the gap if you're not getting enough magnesium from food alone.
When to Use It:
Take 30-60 minutes before bed.
Elite Sleep
Circadian support for travel, shift work, and short-term resets.
What It Is:
A targeted blend of tart cherry powder, L-Theanine, valerian root extract, and melatonin that’s designed to help reset your internal clock and support rest when your rhythm is off.
Why It Works:
Melatonin is a hormone, not a sedative. It's not meant for everyday use, but it’s incredibly effective when used intentionally. Elite Sleep uses a precise dose of melatonin to help realign your sleep-wake cycle when your routine is disrupted.
Who It’s For:
Anyone looking to reset the sleep-wake cycle after periods of high stress, travel, or disrupted sleep.
When to Use It:
Use when looking to reset your sleep-wake cycle after disruption caused by travel, shift work, or periods of high stress. Elite Sleep is not intended for daily use; save it for times when you need to nudge your internal clock back on track.
Apigenin
The calming flavonoid that quiets the noise
What It Is:
A naturally occurring compound found in grapefruit and other plants, Apigenin promotes relaxation and reduces excitability in the brain by acting on GABA receptors.
Why It Works:
Apigenin supports a sense of calm without acting as a sedative. Compared to melatonin, it’s gentler and suitable for consistent, nightly use—especially when anxiety is the barrier to sleep.
Who It’s For:
Ideal for anyone who struggles with getting to sleep; can help alleviate mild anxiety, racing thoughts, and difficulty quieting the mind at night.
When to Use It:
Add apigenin to your nightly wind-down routine, taking it 30-60 minutes before bedtime. Great on its own or stacked with L-Theanine and/or Magtein (Magnesium L-Threonate).
L-Theanine
A calm mind is a powerful one
What It Is:
An amino acid found in green tea that promotes relaxation, reduces stress, and enhances focus—all without sedation.
Why It Works:
L-Theanine increases alpha brain wave activity, the pattern your brain produces during calm, alert wakefulness. It’s ideal for smoothing the transition to sleep—not forcing it.
Who It’s For:
Anyone looking for help to calm and relax their mind before bed. Apigenin can help with sleep onset and depth of sleep.
When to Use It:
Take 30–60 minutes before bed to help ease mental tension. It can also be used during the day alongside caffeine to help temper the jittery crash that some people experience when consuming caffeine by itself.
Inositol
Mood-stabilizing support for anxious nights
What It Is:
Inositol is a sugar alcohol naturally produced in the body that supports neurotransmitter signaling, particularly serotonin and dopamine—critical for emotional regulation and relaxation.
Why It Works:
Inositol is especially effective for people whose sleep struggles stem from anxiety or mood-related imbalances. It supports a calm, emotional baseline, which makes it easier to drift off and stay asleep.
Who It’s For:
If your sleep difficulties are linked to anxiety, stress, or mood fluctuations, Inositol is a good option. It’s especially helpful for those who feel mentally restless, emotionally reactive, or prone to nighttime worry.
When to Use It:
Use nightly or during high-stress periods when feeling anxious. It can also be helpful during the day to support a stable mood and stress resilience.
