Performance Lab Sleep Review

Ever since we were children, we’ve been taught that our best days will come after a solid night’s sleep. In fact, many of us are told that the magic number each night is 8 hours of sleep, and anything less or more than that could make you feel groggy the next day.

As we grow up, that 8-hour goal becomes harder to obtain. Some of us enjoy staying up as late as possible, some of us have jobs that restrict our sleeping patterns, and others will simply find it difficult to fall asleep at night.

No matter the case, it’s imperative that the average adult receives 7-9 hours of sleep each night if they want to function their best the next day. That’s not to say you won’t be able to function if you only get 4-5, but you definitely won’t be as focused, happy, alert, or prepared.

If you’re one of the adults that struggles to maintain a healthy sleeping pattern, you’re not alone. Believe it or not, there are a variety of supplements available that don’t require a doctor’s visit or prescription to acquire. There’s Melatrol, Olly Sleep Gummies, and the one we’ll look at now in this review — Performance Lab Sleep.


What does Performance Lab Sleep have to offer? We’ll take a closer look at this sleep supplement’s ingredients, benefits, and more to help you decide if this it’s the one you’ve been searching for. So, without anything further, let’s dive into this Performance Lab Sleep review!

What Is Performance Lab Sleep?

Sleep is made by Performance Lab and comes in capsule form. Performance Lab has a variety of amazing supplements made for daily relief, including Performance Lab Flex, Performance Lab Omega-3, and Performance Lab Prebiotic. As you can likely imagine, Performance Lab Sleep is designed to enhance your sleep cycles and allow your body to naturally heal, repair, and rest itself for what lies ahead.

One of the things I really enjoy about Performance Lab supplements is how simple they keep the formulas. You’ll only find three ingredients in each capsule — Magnesium+, Montmorency Tart Cherry, and L-Tryptophan — which we will go over shortly. With minimal ingredients, if you’re new to supplements or are extra careful about what you’re putting in your body, Performance Lab Sleep is perfect for you.


Performance Lab takes a different approach than most sleep aids, which will generally provide a high dose of synthetic hormones — like melatonin — to encourage a healthier sleep cycle. Unfortunately, these won’t always do the trick and will sometimes lead to adverse effects in the body.

Performance Lab Sleep provides your body with a natural source of melatonin, as well as ingredients that promote cell-signaling between neurotransmitters, relaxed muscles, and cell regeneration.

To help you better understand how this happens in the body, we’ll detail the role of both hormones and neurotransmitters on your sleep cycles. We’ll also discuss how Performance Lab utilizes the right ingredients to achieve this.

Let’s get started!

How Do Neurotransmitters Affect Sleep Cycles?

You might not think about it on a daily basis, but there are countless (literally, countless) amounts of chemical reactions, processes, functions, and everything alike happening in the body at any given time. When people say your body never stops, they mean it.

Most of you have probably heard of neurotransmitters and hormones before, but don’t exactly know what they are and what they do. In fact, they’ll often be thought of as the same thing when they act completely different.

Neurotransmitters are found in humans — not plants — and belong to the nervous system. They are typically made up of gases, proteins, and amino acids. They are responsible for transmitting nerve signals from one cell to another.

When it comes to sleep, there are a variety of neurotransmitters that play a role, including acetylcholine, GABA, serotonin, dopamine, and norepinephrine. The main one we’re going to talk about here is serotonin because many people will use it for both sleep and wakefulness, which causes some confusion.

With serotonin, it is believed that too much of it causes wakefulness, and too little will lead to bad sleep patterns. At the same time, serotonin is also known as a precursor to melatonin. This means that melatonin can’t be produced in the body without serotonin — which actually leads us to the next question.

How Do Hormones Affect Sleep Cycles?

The reason we’re going to be talking about hormones is because that’s what melatonin is classified as. Melatonin, which we briefly mentioned earlier, is known as the “hormone of darkness” because it is released in the body as a response to darkness.

This response is what tells our body it’s time for bed. This is why it might be hard to fall asleep when you go from a lighted room directly into your bed to sleep. It’s also why electronics, phone screens, and laptops (which blast your face with light) can disturb your ability to sleep.

These things all suppress melatonin, meaning your body isn’t getting the hint that it’s time to “turn off.” Irregulated melatonin levels can also affect how you wake up. When melatonin levels naturally start to decrease as the sun rises in the morning, it acts as an internal alarm clock.

Without serotonin, your body will struggle to produce melatonin. Without melatonin, your body will struggle to figure out when it’s time for bed, when it’s time to wake up, and when it’s time to enjoy your day — otherwise known as your circadian rhythm or internal clock.

And as you can probably imagine, this will lead to a wide range of reactions and responses in the body that will contribute to stress, depression, loss of motivation, and much more.

Does Performance Lab Make Any Claims For Sleep?

Performance Lab makes several claims about Sleep, but they fall in line with everything we’ve mentioned up to this point. Overall, they claim to give you the best sleep you’ve had in a long time, allowing you to wake up refreshed, regenerated, and ready for the day ahead.

The reason we’ve talked so much about serotonin and melatonin is because those are the two main factors in Performance Lab Sleep. Unlike most sleep aids that add a high dose of synthetic melatonin, Sleep provides a natural source of melatonin from Montmorency Tart Cherry.

In addition to that, they claim the L-Tryptophan in Sleep will act as a signal for neurotransmitters like serotonin. As we mentioned previously, the increased serotonin levels will lead to a higher amount of melatonin in the body — promoting the onset of sleep and extended regeneration of your cells.

Here’s a full list of the claims made by Performance Lab:

  • Supplies melatonin and signals for serotonin
  • Relaxes muscles and nerves
  • Reduces aches, spasms, and movements throughout the night
  • Renews and revitalizes cells 
  • Non-habit-forming sleep aid
  • Added probiotic-infused magnesium
  • Free of allergens, banned substances, gluten, soy, synthetic additives, and caffeine
  • Non-irradiated, non-GMO, vegan-friendly, and GMP-certified

Despite only containing three ingredients, Sleep by Performance Lab claims to do a lot for the body and even more for your sleep cycles/circadian rhythm.

Can You Combine Sleep With Other Performance Lab Products?

Performance Lab Sleep is designed to help you get the most out of your night with enhanced sleep, but what about the rest of your day?

Don’t worry; Performance Lab has you covered with a wide range of powerful supplements designed for everyday use (and I mean a wide range). If you’re looking for something that will stack well with Sleep, you can test the following out:

  • NutriGenesis Multi – a multivitamin that comes in a formula designed for men and one designed for women
  • Mind support your brain with Citicoline, Phosphatidylserine, L-Tyrosine, and Maritime Pine Bark Extract
  • Post – restore, repair, and grow your muscles with this sports drink in a capsule designed for after a workout
  • Maintain – similar to the Post supplement, but designed for your off days with extended-release muscle support
  • Protein – a protein powder from brown rice combined with vitamins, minerals, and Himalayan Pink Salt

As you can see, Sleep is not only a powerful supplement by itself, but it can be maximized by stacking with other Performance Lab products.

At the end of the day, Performance Lab Sleep will provide more than enough for your body if you’re simply after a good night’s sleep.

Performance Lab Sleep Ingredients

Now that we’ve covered pretty much everything there is to know about sleep, and what Performance Lab intends their capsule to do, it’s time to dig into the good stuff.

Sleep by Performance Lab supplement facts

There will only be three ingredients total — Montmorency Tart Cherry, Magnesium +, and L-Tryptophan — but they will each benefit the body and brain in a multitude of ways. Let’s see what makes these ingredients so special and why Performance Lab chose to utilize them in Sleep.

Magnesium + (100mg)

The first ingredient used in Sleep is actually a combination of three different forms of the same ingredient — magnesium. Magnesium has an overwhelming amount of responsibility in our body, which is largely why it is considered an essential mineral.

In addition to regulating blood sugar levels, nerve and muscle function, blood pressure, and producing DNA, magnesium has several effects on sleep. It is known to calm your nerves, soothe muscles, to prevent twitches and movements, and promote sleep onset.

The three forms of magnesium found in Sleep are:

  1. Magnesium Bisglycinate – magnesium bonded to glycine, which can help increase serotonin levels and improve nutrient absorption
  2. Magnesium Taurate – magnesium bonded with taurine, which helps regulate the release of both GABA and melatonin
  3. NutriGenesis® Magnesium – patented by Performance Labs, this magnesium is cultivated with probiotics that are known to help reduce cortisol levels in the body

In addition to those great benefits, magnesium has also been identified as a cofactor when converting L-tryptophan to serotonin. As a result, this mineral works hand-in-hand with the next ingredient found in Sleep.

Recommended Dosage: 300-400mg per day

L-Tryptophan (250mg)

It’s no wonder why Performance Lab chose to utilize L-Tryptophan in Sleep. Not only does it work well alongside magnesium, but it also helps produce the two major hormones and neurotransmitters we’ve been talking about this whole time — serotonin and melatonin.

In the brain, L-Tryptophan will first convert into 5-HTP before converting into serotonin. As we all know by now, serotonin will play a major role in regulating mood, sleep patterns, appetite, digestion, and promoting relaxation.

In the gastrointestinal (GI) tract, L-Tryptophan is converted into melatonin. Of course, this is what tells our body it’s time for sleep.

With these two processes happening simultaneously, you’ll find yourself going to sleep easier, staying asleep easier, waking up more energized, and feeling happier throughout the day.

Recommended Dosage: 100-250mg per day

Montmorency Tart Cherry (500mg)

I’m sure we’ve all heard of the all-famous cherry. Grown in Europe, Canada, and the United States, Montmorency Tart Cherries are a type of sour cherry known to be high in potassium, fiber, antioxidants, and beta-carotene.

Believe it or not, this cherry is also a natural source of melatonin — and a healthy one at that! Where most supplements utilize high doses of synthetic melatonin, we provide a minimal dosage of natural melatonin.

The difference isn’t necessarily in sleep onset, but in the grogginess felt the next day. With a minimal dosage that delivers just enough to provide sleep benefits, you won’t have a nasty “hangover” the next day.

The antioxidants will also work in your body’s favor by soothing your joints and muscles. This promotes relaxation and allows you to fall asleep without disruption.

Recommended Dosage: No more than 2,500mg per day

Performance Lab Sleep Dosage, Packaging, And Pricing

If you’ve come across any of Performance Lab’s other supplements, you’ll notice something similar about this product — the packaging! It’s honestly a smart marketing choice that allows for greater brand awareness and recognition.

There are subtle differences, however, to help determine what supplement is what. Sleep utilizes a purple and orange logo, which is actually just a giant square with a moon in the top left.

The rest of the bottle, outside of the words “Performance Lab Sleep” and the nutrition label, is completely white. The bottle also comes in a box, with the same basic design on it.

The dosages are properly labeled for each ingredient on the back of the bottle — 500mg of Montmorency Tart Cherry, 100mg of Magnesium+, and 250mg of L-Tryptophan.

Each bottle will come with 30 capsules, enough for a month’s supply.


You’ll have three choices when purchasing Sleep: a one-month supply for $39, a two-month supply for $78, or a three-month supply for $117. Those might seem like the same price, but the only difference is you’ll earn a free one-month supply with the purchase of a three-month.

Claims vs. Reality

We touched base on the various claims made by Performance Lab in regards to Sleep, earlier in this review. Now that we’ve gotten a full look at what this sleep aid provides and what to expect out of it, it’s time to see if the two sides match up.

Like most Performance Lab products, it’s safe to say Sleep is one of the best — if not the best — sleep aid on the market today. It provides natural melatonin and helps the body signal for serotonin in a variety of ways.

In addition to that, the three different forms of Magnesium provide three amazing benefits in taurine, glycine, and probiotics. You’ll feel more relaxed, your muscles and nerves will be ready to tone it down for the rest of the night, and your body will be prepared to restore and revitalize itself while you get your well-needed rest.

Looking at their website, it might seem like Performance Lab is full of claims and guarantees. If you look closer, however, you’ll notice they’re all about spreading facts with scientific research to back it.

Claims = Reality with this one.

If you’re someone who hears the term “beauty sleep” and immediately responds with, “What’s that?” then it’s time to take a look at Performance Lab Sleep. This supplement is designed to add that beauty to your sleep so you can wake up ready to take on the world.

There are a lot of sleep aids out there, but Performance Lab has landed their product at the top of my list. To be honest, it’s quite amazing what three ingredients can do for your body in such a short time.

With Performance Lab Sleep, you can finally ditch all those melatonin tablets and bedtime gummies that simply don’t work. Two capsules per day and you’ll be having the best sleep of your life!
