Performance Lab Sleep Review

Ever since we were children, we have 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 is imperative that the average adult receives 7-9 hours of sleep each night if they want to function their best the next day. That is not to say you will not be able to function if you only get 4-5, but you definitely will not be as focused, happy, alert, or prepared.

If you are one of the adults that struggle to obtain quality sleep, you are not alone. Believe it or not, there are a variety of supplements available that do not require a doctor’s visit or prescription to acquire. There is Melatrol, Olly Sleep Gummies, and the one we will look at in our Performance Lab Sleep review.


What does Performance Lab Sleep have to offer? We will take a closer look at this sleep supplement’s ingredients, benefits, and more to help you decide if this is the one you have been searching for. So, without anything further, let us 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 a sleep supplement designed to enhance your sleep cycles and allow your body to naturally heal, repair, and rest itself for what lies ahead with better sleep quality. 

One of the things I really enjoy about Performance Lab supplements is how simple they keep the formulas. You will 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 are new to supplements or are extra careful about what you are putting in your body, Performance Lab Sleep is perfect for you.


Performance Lab takes a different approach than most sleep supplements, which will generally provide a high dose of synthetic hormones — like synthetic melatonin — to encourage a healthier sleep cycle. Unfortunately, these will not always do the trick and will sometimes lead to adverse effects on 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 will detail the role of both hormones and neurotransmitters on your sleep cycles. We will also discuss how Performance Lab utilizes the right ingredients to achieve this.

Let us take a look at this natural sleep supplement below and see how it performs next to other sleep supplements.

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 do not know exactly what they are and what they do. In fact, they will often be thought of as the same thing when they act completely differently.

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 in helping you get deep sleep, prevent sleep deprivation, and aid in making your body stay asleep. Some neurotransmitters involved in the sleep cycle are acetylcholine, GABA, serotonin, dopamine, and norepinephrine. The main one we are going to talk about here is serotonin because it is involved in 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 cannot be produced in the body without serotonin — which actually leads us to the next question.

How Do Hormones Affect Sleep Cycles?

The reason we are going to be talking about hormones is that melatonin is often referred to as one. 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 is 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 is 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 is not getting the hint that it is time to “turn off.” Irregular melatonin levels can also affect how you wake up. Usually, melatonin levels naturally start to decrease as the sun rises in the morning, acting 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 is time for bed, and when it is time to wake up, and when it is time to enjoy your day.  This process is 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 have mentioned up to this point. Overall, they claim to give you the best sleep you have had in a long time, allowing you to wake up refreshed, regenerated, and ready for the day ahead.

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

In addition to that, they claim the L-Tryptophan in this sleep supplement will act as a signal for neurotransmitters like serotonin. As we mentioned previously, the higher 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 is 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?

Do not 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 are looking for something that will stack well with Sleep, you can test the following out:

  • NutriGenesis Multi- 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 have covered pretty much everything there is to know about sleep, and what Performance Lab intends its capsule to do, it is 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 us see what makes these ingredients so special and why Performance Lab chose to utilize them in Performance Lab Sleep.

Magnesium + (100mg)

The first ingredient used in this Sleep supplement 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, 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 is 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 have 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 is time for sleep.

With these two processes happening simultaneously, you will find yourself going to sleep easier, having restful sleep, waking up more energized, and feeling happier throughout the day.

Recommended Dosage: 100-250mg per day

Montmorency Tart Cherry (500mg)

I’m sure we have 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, Performance Lab Sleep provides a minimal dosage of natural melatonin.

The difference is not 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 will be using a natural sleep aid without 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 Supplement Benefits 

There is a lot to love about this product, particularly when you look at Performance Lab Sleep reviews. Still, we understand if you are still on the fence about this product — it is a normal part of the supplement-buying process.

If you need further convincing, we have you covered with a list of benefits and possible downsides to consider with Sleep. This list should let you know whether Performance Lab Sleep beats your usual melatonin supplements and if it is the answer for the quality sleep you need. 

Sleep by Performance Lab for sleep

Natural Source of Melatonin

While many think that synthetic melatonin is the answer to all sleep problems, sometimes it can actually mess up your deep sleep cycle and can lead to problems when you try to stay asleep. That is why Performance Lab Sleep prefers to give you real melatonin in a small dosage, and ingredients that will produce natural melatonin in your body. 

It also happens that tart cherry in Performance Lab Sleep is also high in vitamins, minerals, and antioxidants. 

More Serotonin Production 

Your quality sleep is highly dependent on serotonin, and that is why a natural sleep supplement that contains magnesium and tryptophan is ideal. Serotonin is also a predecessor to melatonin, stimulating normal sleep signals that help you get quality sleep. 

Serotonin can work on the pineal gland as well to promote more melatonin production and improve your circadian rhythm. 

Good Source of Magnesium 

More than just preventing a magnesium deficiency, your body will also receive glycine and taurine, two sleep-promoting amino acids. Taurine also happens to help produce GABA, a neurotransmitter that aids in sleep and memory problems. 

Also, the NutriGenesis Magnesium formula in Performance Lab Sleep also contains probiotics, which can lead to better gut health too. 

No Hidden Ingredients

The mixture of ingredients in Performance Lab Sleep is straightforward, nothing is hidden. Your supplement will be allergen-free, gluten-free, and soy-free, with no additives, banned substances, or caffeine. 

It also happens to be non-GMO, vegan-friendly, and GMP-certified. 

Easy to Take

Since Performance Lab Sleep is all-natural, it is also easy to take. You can just take two capsules half an hour before sleep and see great results. It also gives you the ability to increase the dosage to two servings (4 capsules) before bed

To maximize your sleep quality, you can mix and match other Performance Lab products with this sleep supplement.

A product like this will always come with some downsides. You have to wonder, does Performance Lab Sleep work? Before you buy Performance Lab Sleep, take a look at these few points to remember. 

  • Can be rather expensive at $1.30 per serving
  • It could also have added L-Theanine and Ginkgo Biloba to make the formula more wholesome 
  • Only available on the Performance Lab website. 

30-day promise

Performance Lab Sleep Dosage, Packaging, And Pricing

If you have come across any of Performance Lab’s other supplements, you will notice something similar about this product — the packaging! It is 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 will 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.

It also happens that this Performance Lab product is backed by a 30-day performance promise. You can try this sleep supplement for 30 days and if you do not see an improvement when you want to fall asleep, in getting deep sleep, or in improving your sleep quality, then you can return the product for a full refund.

Claims vs. Reality

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

Like most Performance Lab products, it is safe to say Performance Lab 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 serotonin in a variety of ways.

In addition to that, the three different forms of Magnesium provide three amazing benefits: taurine, glycine, and probiotics. You will feel more relaxed, your muscles and nerves will be ready to tone it down for the rest of the night, be able to fall asleep faster, and have a good night’s sleep. Your body will be prepared to restore and revitalize itself while you get your well-needed rest.

Unlike synthetic melatonin supplements, this is one of those natural sleep aids that does not affect the nervous system in such a way as to create dependence. Healthy sleep cycles can be achieved without dependence on sleeping pills or using multiple sleep aids. In fact, you can also get more than one essential amino acid and create consistent sleep patterns. 

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

Claims = Reality with this one.


Final Verdict: Performance Lab Sleep Review 

If you are someone who hears the term “beauty sleep” and immediately responds with, “What’s that?” then it is 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 Sleep solves your issues without putting you in harm’s way for good quality sleep. 

Performance Lab has landed its product at the top of my list. To be honest, it is 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! Plus, if you do not see it as one of the best natural sleep aids and are not happy with the results, then you can get a full refund.
