The Science

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

Melatonin levels

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.


Montmorency Tart Cherry is a natural source of sleep-inducing melatonin.

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.

L-Tryptophan, 250 mg


L-Tryptophan supports bright daytime mood and calm nighttime relaxation.

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 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.

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:

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

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.

Sea buckthorn, 100 mg

Sea buckthorn is a rich source of bioactive compounds including serotonin.

Serotonin is a neurotransmitter involved in the regulation of the sleep-wake cycle, promotion of wakefulness during the day and facilitation of sleep at night.

Additionally, sea buckthorn provides an array of vitamins, minerals and antioxidants which help foster a healthy sleep environment in the body, allowing for more restful nights.

Performance Lab® Sea Buckthorn is a certified-organic juice powder providing the full spectrum of vitamins, minerals and bioactives contained within fresh sea buckthorn berries.

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.

What is NutriGenesis®?

NutriGenesis® is a Performance Lab® nutrition technology innovation: Vitamins, minerals and amino acids grown in live cultures at our state-of-the-art lab.

A true biological nutrient form, NutriGenesis® closely mirrors the molecular structure of food nutrients. NutriGenesis® nutrients offer significant advantages over standard nutrient forms.

Featured in several Performance Lab® formulas, NutriGenesis® vitamins, minerals and amino acids are bioengineered to be safe, active and highly effective for overall health and performance.

Why did Performance Lab® develop NutriGenesis®?

Vitamins, minerals and amino acids are the most important nutrients you need to build a strong foundation for health and performance.

Performance Lab® developed NutriGenesis® to have our own in-house vitamins, minerals and amino acids to use in our own nutritional supplements.

In producing NutriGenesis®, Performance Lab® can best maintain our industry-leading quality standards for cleanliness, purity, effectiveness and eco-friendliness, across all our ultramodern formulas.

How is NutriGenesis® different from other nutrient forms?

Not all vitamins, minerals and amino acids are the same. There are many nutrient forms, produced with a variety of processes. Some of the most popular nutrient forms available in supplements today include:

Whole Food Concentrates

Whole food vitamin and mineral supplements are sourced from fruits, vegetables, herbs and mushrooms. They include natural cofactors that make food nutrients so easy for the body to absorb and utilize. However, they do require extensive processing and may be made with GMOs, mass agriculture and dirty eco-destructive practices.

Isolated Chemical (USP) Nutrients

Isolated Chemical (USP) is the cheapest vitamin and mineral form found in the most basic multivitamin supplements. This synthetic form chemically alters vitamins and minerals, isolating them from their whole-food cofactors. As a result, Isolated Chemical (USP) nutrients are typically harder to absorb and less effective than whole food nutrients.

Chelated Minerals

In this process, a mineral nutrient (such as iron, calcium, zinc) is bound with a chelator: An organic molecule (often an amino acid) that is large enough to enrobe the mineral. By surrounding the mineral, the chelator protects it against degradation. Chelated nutrients are highly stable and may improve nutrient uptake and utilization.

NutriGenesis® is different from traditional nutrient forms: Bioengineered to be better.

NutriGenesis® are cultured nutrients that replicate the creation of vitamins, minerals and aminos in nature.

NutriGenesis® is based on the work of Nobel Prize-winning physiologist Albert Szent Gyorgy, who theorized that nutrients presented in their naturally grown forms supply cofactors that make them more bioavailable, biologically active and effective than nutrients that are isolated.

In the NutriGenesis® process, single-cell organisms are seeded with micronutrients in a hydroponic growth medium.

The live single-cell organisms “eat” the micronutrients, divide and thrive. As the cultures grow, they produce fresh new NutriGenesis® vitamins, minerals and aminos within a matrix of natural cofactors. This familiar structure is more easily absorbed and utilized by the body.

More on the NutriGenesis® Process

NutriGenesis® advantages over other forms:

NutriGenesis® is essentially food nutrition. Mirroring food nutrients molecule-by-molecule, our vitamins, minerals and aminos are presented in pure elemental form. Maximum nutrition: Nothing more, nothing less.

Enhanced effectiveness. Because NutriGenesis® nutrients are in food-matrix form, they are recognized by the body as nature-identical -- maximizing nutrient uptake, bioavailability and beneficial activity.

Patented and researched. The patented process behind NutriGenesis® has been shown in research to enhance nutrient absorption and retention (when compared to chemical isolates).

Cleaner and safer. NutriGenesis® is produced in a sterile, tightly controlled lab setting. NutriGenesis® is minimally processed, requiring no pesticides, herbicides or other synthetics associated with some other whole-food nutrients.

Better for the planet: The NutriGenesis® process is clean and efficient, with little carbon footprint or environmental impact – especially when compared to factory farming for phytonutrients and strip mining for minerals.

Which formulas feature NutriGenesis® nutrients?

It all begins with NutriGenesis® Multi for Men and Multi for Women: Performance Lab®’s multivitamin starting point for human performance optimization.

NutriGenesis® vitamins, minerals and amino acids are also found in Performance Lab® formulas Stim, Flex, BCAA, Pre, Post and Maintain.

Beyond Performance Lab®, NutriGenesis® B-Vitamins are found in Mind Lab Pro®: the Universal Nootropic™.
