Note: Durable SLEEP is new and improved with a completely reimagined, science-backed formula—now just one capsule per night! Most people struggle with sleep not because they aren't tired, but because their nervous system can’t wind down—so that's exactly what we set out to fix.*

We've replaced the previous ingredients in Durble SLEEP with three patented, clinically validated ingredients—Sleeproot™ valerian extract, Relissa® Lemon Balm Phytosome™ and Somato® phyto-melatonin—each targeting a distinct driver of restorative sleep. This new formula reduces the daily dose from two capsules to one, includes low-dose, plant-derived natural melatonin, and upgrades to a more sophisticated dual-pathway approach to GABA support for deeper, more sustained sleep night after night.*

Dr. Passero reformulated Durable SLEEP based on the latest research breakthroughs as well as innovations being used in his clinic. It works in harmony with your natural sleep architecture to support lasting improvements, providing the most restorative benefits of sleep without relying on superficial short-term sedation.*

Durable SLEEP uniquely combines clinically validated botanicals at therapeutic doses with low-dose, naturally derived plant-based melatonin that calms your brain, eases stress signals and reinforces circadian rhythm alignment so you fall asleep easily, stay asleep and wake up refreshed. Best of all, it’s non-habit-forming and designed for safe, long-term use.*

At the core of this cutting-edge formula is a clinically studied 200 mg dose of Sleeproot™, a patented, standardized valerian extract that supports GABA-A receptor activity—the brain's natural calming pathway. Backed by human studies, Sleeproot™ is proven to reduce time to fall asleep in as little as 1-3 days, significantly improve sleep quality within 2 weeks and increase total sleep time by roughly 60 minutes—with results more than 20x greater than placebo.*

Durable SLEEP also includes 400 mg of Relissa® Lemon Balm Phytosome™—4.2x more effective at preserving GABA—to quiet the "tired but wired" mind. While Sleeproot™ activates GABA-A receptors to initiate calm, Relissa® works synergistically by slowing GABA breakdown, amplifying the calming effect beyond what either ingredient achieves alone.*

In clinical research, Relissa® significantly reduced nighttime cortisol and produced a 190% improvement in sleep quality versus placebo—with 87% of participants reporting significant improvements.*

Durable SLEEP also features Somato® phyto-melatonin, a superior plant-derived melatonin intentionally dosed at just 2 mg. Many brands rely on high-dose synthetic melatonin, but these mega doses act more like a sedative than genuine sleep support—disrupting circadian timing and causing vivid dreams, early awakenings and grogginess. Durable SLEEP's physiologic 2 mg dose gently realigns your natural sleep-wake cycle, offering lasting support rather than a chemical shortcut.*

If you have trouble falling asleep, staying asleep or shutting off a busy mind, Durable SLEEP delivers a comprehensive, science-backed solution for consistent nightly use—without excessive sedation or morning fog.*

Durable SLEEP was designed to do what most sleep supplements can't: help you fall asleep faster, stay asleep through the night and wake up feeling genuinely refreshed—without sedation, grogginess or next-day fog.*

Most sleep products fail because they treat sleep as a single problem with a single solution. In reality, sleep is the result of multiple systems working in sequence—neurotransmitters that allow the brain to quiet down, stress signals that must finally disengage and circadian rhythms that tell your body when sleep should begin. Target only one of these, and the others can still keep you awake.*

Doctor-formulated by Dr. Kevin Passero—drawing on more than 20 years of clinical practice—Durable SLEEP addresses all three drivers simultaneously through a synergistic blend of clinically validated, non-sedating ingredients that work with your body's natural sleep physiology. It's built for the long game: meaningful, lasting sleep improvement with consistent nightly use.*

Sleeproot™ Valerian Extract: Clinically Proven Results, Starting in Days (200 mg)
At the core of Durable SLEEP is a 200 mg dose of Sleeproot™, a patented, clinically validated valerian extract standardized to ≥2.0% valerenic acids—the active compounds most strongly associated with valerian's sleep-promoting effects.*

Unlike many sleep ingredients validated only by how people feel they slept, Sleeproot™ has been shown using objective clinical sleep monitoring—the same tools used in medical sleep labs—to deliver measurable, verifiable results.*

Rather than sedating the brain, Sleeproot™ supports GABA-A receptor activity—the brain's primary inhibitory pathway—reducing excessive neuronal firing so the mind can naturally transition into and sustain sleep.*

In clinical trials, Sleeproot™ has been shown to:*

• Reduce time to fall asleep in as little as 1-3 days
• Significantly improve sleep quality by day 14—with continued improvements through day 56
• Increase total sleep time by ~56 minutes versus placebo
• Improve sleep efficiency by over 11% versus placebo at day 56
• Deliver results more than 20x greater than placebo

Relissa® Lemon Balm Phytosome™: Silencing the "Tired-But-Wired" Mind (400 mg)
Many people don't have trouble sleeping because they aren't tired—they have trouble sleeping because their nervous system won't turn off. Relissa® Lemon Balm Phytosome™ was included specifically to address the "tired but wired" state of cognitive and emotional hyperarousal that keeps people lying awake despite exhaustion.*

While Sleeproot™ works by activating GABA-A receptors, Relissa® targets a distinct and complementary mechanism—inhibiting GABA-transaminase, the enzyme responsible for breaking down GABA in the brain. The result is that more GABA stays active longer, deepening and extending the calming effect beyond what either ingredient could achieve alone.*

Relissa®'s advanced Phytosome™ delivery system—which bonds the lemon balm extract to a phospholipid matrix for enhanced bioavailability—makes it 4.2x more effective at preserving GABA than standard, unformulated lemon balm. A 4.2x difference in GABA preservation isn't a minor formulation detail—it's the margin between a clinically meaningful formula and an ineffective one.*

Relissa® also directly addresses one of the most overlooked drivers of poor sleep: elevated nighttime cortisol. By significantly reducing cortisol levels in as little as one week, it dismantles the physiologic stress response that keeps the brain in a state of hypervigilance after the lights go out.*

In clinical research, Relissa® produced:*

• 190% improvement in sleep quality versus placebo
• 87% of participants reporting significant improvements (versus 30% with placebo)
• 15% increase in deep, restorative slow-wave sleep
• Reduced REM disruption and nighttime restlessness

Somato® Phyto-Melatonin: The Right Sleep Signal, at the Right Dose (2 mg)
Most people think melatonin causes sleep. What it actually does is signal the brain that it's time to begin the sleep cycle—and the dose required to do that job well is far lower than what most products provide.*

Many brands load their formulas with 5, 10 or even 20 mg of synthetic melatonin—not because the science supports it, but because it's cheap to produce and makes consumers feel something is "working." At doses this high, melatonin stops functioning as a circadian signal and starts acting pharmacologically. This suppresses the central nervous system in ways that frequently cause vivid dreams, early morning awakenings and the kind of morning grogginess that leaves people feeling worse, not better.*

Physiologic doses in the 0.3-2 mg range are sufficient for circadian rhythm support—and the clinical data bears this out. In a trial comparing doses directly, 1-3 mg of phyto-melatonin outperformed 10 mg synthetic melatonin in participants with diagnosed sleep concerns.*

There is also a purity concern worth knowing about. A peer-reviewed study published in the Journal of Clinical Sleep Medicine found that over 70% of commercially available melatonin supplements failed to meet acceptable label accuracy standards—with actual content ranging from 83% below to 478% above the stated dose. More troublingly, 26% of products tested contained serotonin, a prescription-strength neurotransmitter with no place in a nightly supplement—particularly concerning for those taking SSRIs or other medications.*

Durable SLEEP uses Somato® phyto-melatonin—plant-derived from tomatoes, independently verified for identity and purity through Alkemist Assured® third-party authentication, and intentionally dosed at 2 mg. This physiologic dose gently reinforces your body's natural sleep-wake timing without overwhelming your system—providing the circadian signal that allows Sleeproot™ and Relissa® to do their jobs at exactly the right moment.*

How Durable SLEEP's Ingredients Work Together
Three ingredients. Three distinct barriers to restorative sleep. Each one targeted, each one amplifying the others:*

• Somato® phyto-melatonin sets the circadian clock—signaling the brain that it's time to begin the sleep cycle.
• Relissa® quiets the cognitive and emotional noise that blocks sleep onset—reducing cortisol, calming racing thoughts and creating the mental conditions sleep requires.
• Sleeproot™ allows the brain to cross the threshold into sustained, restorative sleep—and stay there through the night.

Rather than sedating the system into submission, each ingredient removes a specific barrier to natural sleep—and makes the other two more effective in the process.*
