Ultramodern sleep aid helps you wake in the morning ready to perform

Some sleep aids supply one large dose of synthetic melatonin, only – a one-dimensional strategy associated with morning grogginess.

Rather than synthetic high-dose, Performance Lab® Sleep supplies natural low-dose melatonin from CherryPURE® Montmorency tart cherry.

With additional joint- and muscle-soothing antioxidants, CherryPURE® promotes deep sleep better than any synthetic melatonin can.

Sleep TryptoPure® synergizes with CherryPURE®, encouraging natural melatonin + serotonin for drowsiness. Finally, 3 magnesium forms (including NutriGenesis®) promote sleep-supportive muscle relaxation.

Supplement Facts

Upgrade Your Sleep Aid with a Natural
Melatonin Innovation

Melatonin is a neurotransmitter-like hormone produced by the pineal gland that regulates sleep cycles:

  • Darkness stimulates melatonin release, producing sleep-inducing sedation;
  • Light inhibits melatonin release, which signals for the brain to wake up.

Concern: Melatonin is greatly affected by light. Nighttime use of electronic devices and artificial light suppresses melatonin release – making it harder to fall asleep while disrupting sleep patterns over time.

Melatonin levels

Melatonin supplements help, but many use synthetic melatonin in unnatural megadoses that lead to grogginess and brain fog throughout the day.

Performance Lab® Sleep presents a better way: Supplying melatonin from Montmorency tart cherry while encouraging the pineal gland’s natural melatonin production and release.

With additional support for muscle relaxation, soothing body comfort and tranquil bedtime drowsiness, Sleep delivers a superior night’s rest so you wake up clear-headed, revitalized and primed to perform.

CherryPURE® Montmorency tart cherry,
50:1 concentrated ratio, 500 mg

Montmorency tart cherry is the richest natural source of melatonin – supplying a minimum effective melatonin dose for sleep enhancement without the daytime grogginess associated with synthetic melatonin megadoses.

Montmorency tart cherry melatonin supports restful slumber and healthy sleep patterns by:

  1. Emulating the sedating effects of bedtime darkness to induce faster, easier sleep onset;
  2. Correcting melatonin disruptions caused by night-time use of electronic devices;
  3. Regulating circadian rhythm to establish healthy, consistent sleep patterns over time

In addition to enhancing sleep quality with natural melatonin, Montmorency tart cherry supplies anthocyanin antioxidants that help you stay asleep by soothing achy muscles and joints.


Performance Lab® Sleep CherryPURE® is a nutrition technology advancement that concentrates Montmorency tart cherry to a potent 50:1 extract. Sleep’s 500 mg CherryPURE® equates to 25 g Montmorency tart cherries.

TryptoPure® L-Tryptophan, 250 mg


Stress and mood imbalances disrupt sleep. Poor sleep quality then leads to daytime irritability – creating more stress that worsens sleep patterns further.

The amino acid L-Tryptophan helps break this unhealthy stress-sleep cycle with versatile mood and sleep support, working by:

  1. Converting in the brain into 5-HTP, which then converts into serotonin: A brain chemical for mood, relaxation and sleep;
  2. Converting into melatonin in the GI tract while also optimizing the pineal gland’s natural production of melatonin.

As it promotes synthesis of complementary, sleep-supportive brain chemicals, L-Tryptophan supports a bright daytime mood, calm bedtime sedation, and healthier sleep patterns over time.

Performance Lab® Sleep TryptoPure® L-Tryptophan is a next-generation form sourced from non-GMO, gluten-free vegetables using patented, eco-friendly Ferment-A-Pure™ technology.

Magnesium 100 mg
(Bisglycinate + Taurate + NutriGenesis® )

Magnesium catalyzes 300+ life-sustaining bioactivities, including key functions that help us fall asleep and stay asleep. Magnesium supports sleep by:

  1. Calming excitable nerve impulses transmitted across neuromuscular junctions;
  2. Supporting the soothing muscle relaxation that precedes sleep onset;
  3. Relaxing vascular smooth muscle cells for a gentle sleep-inducing blood pressure drop;
  4. Reducing sleep-disruptive involuntary muscle twitches and limb movements.
Magnesium Taurate
Magnesium Bisglycinate

Ongoing sleep problems are linked to magnesium deficiency. This is compounded by:

  • 60% of adults failing to get enough daily magnesium from diet alone
  • Typical hard-to-absorb magnesium supplements; only 30%-40% bioavailable

Performance Lab® Sleep conquers magnesium challenges with an advanced 3x matrix designed for high bioavailability and superior sleep support:

  • Magnesium Bisglycinate is a chelated mineral form bound with glycine (another sleep-supportive amino acid) that enables greater absorption in the intestines
  • Magnesium Taurate binds magnesium with taurine, an amino acid that promotes the relaxing and calming brain chemical GABA for additional sleep onset support
  • NutriGenesis® Magnesium is Performance Lab®’s nutrition technology breakthrough: Clean, probiotic-cultured magnesium complexed with absorption-boosting cofactors

Performance Lab® Sleep Magnesium + L-Tryptophan Serotonin Stack: Magnesium is a cofactor in the conversion of L-Tryptophan to serotonin: A brain chemical for relaxation, melatonin release and sleep.

Who should take Performance Lab® Sleep

Sleep can be taken by anyone seeking safe, natural support for restful sleep. This Performance Lab® formula can help with a wide range of sleep concerns, including disruptions tied to muscle tension, involuntary limb movements, apnea, stress and mood.

Sleep ingredients also help to enhance cell renewal, optimizing physical recovery during sleep after training and working out. Sleep’s nutrition for muscle and joint comfort offer additional soothing sleep support for active individuals.

How do I take Performance Lab® Sleep

Take 2 to 4 capsules, 30 minutes before sleep. For best results use daily and consistently.

How does Performance Lab® Sleep work?

Sleep is designed to optimize several sleep-related body systems and bioactivities. It relaxes the muscles, nervous system and mind to help you to fall asleep faster and stay asleep longer.

As it supports regenerative sleep phases and healthy sleep cycles over time, Sleep optimizes tissue repair, cell renewal and healthy function across all body systems.

Most importantly, Sleep helps you wake up feeling energized and refreshed, without the grogginess associated with some synthetic sleep aids.

Is Performance Lab® Sleep safe?

Like all Performance Lab® supplements, Sleep is designed to be safe for long-term daily use. Sleep is an effective, non-habit-forming sleep aid, made with pure, potent ingredients that are dosed appropriately and in line with clinical research. Sleep’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives, further supports tolerability and safety.

How long does Performance Lab® Sleep take to work?

Sleep is taken before bedtime. It induces slumber quickly by supporting mind-body relaxation and comfort. Ongoing supplementation with Sleep supports healthy, consistent circadian rhythms that support restful sleep patterns and contribute to overall health.

Why is Performance Lab® Sleep magnesium listed as 100mg only, when the sources listed appear to supply much more magnesium?

Sleep uses three forms of magnesium, each of which are complexed with complementary nutrients including glycine, taurine and magnesium cofactors that help the body utilize the mineral more efficiently. Although the magnesium sources in Sleep are listed as 700 mg, the total elemental magnesium content is 100 mg, with complementary support nutrients comprising the remainder.

Why doesn’t Performance Lab® Sleep supply melatonin?

Sleep does supply melatonin; it is just not listed as such on the label. Typical sleep support supplements often supply a dose of synthetic melatonin. Sleep is different: It supplies Montmorency Tart Cherry – one of the richest sources of natural melatonin – while also supporting the pineal gland’s natural production of melatonin. This design raises melatonin via two pathways and fits our philosophy of using natural ingredients whenever possible.
