Performance Lab Sleep is a premium sleep product that helps you – you’ve guessed it – sleep better.

This supplement features patented, clinically-tested, and natural ingredients such as magnesium and l-tryptophan to enhance your sleep.

  • Additionally, Performance Lab Sleep uses a natural form of melatonin sourced from tart cherries.

This is rare to see among sleep supplements nowadays – most companies use cheap and synthetic melatonin which isn’t nearly as effective.

Now, while Performance Lab Sleep looks to be a promising supplement, we can’t help but wonder: is it really as good as they say?

Performance Lab Sleep is a supplement of impressive quality.

Not only does it uses a natural form of melatonin (which is rare to see), but other ingredients such as magnesium come from nature-identical sources too.

The product even uses biodegradable plant caps for improved absorption in your body. And the packaging is recyclable.


Among the benefits Performance Lab Sleep claims, a few stand out:

  • Nightly regeneration support
  • Peak daytime performance
  • Improved sleep

Now, there’s only one way to know if these benefits are actually true.

It’s by inspecting the ingredients:


Montmorency Tart Cherry Extract (500mg, 50:1 CherryPURE Extract)

Montmorency Tart Cherry is one of the best natural sources of melatonin.

This fruit contains high levels of the sleep hormone, helping you relax and unwind before bed.

  • Research shows tart cherry juice helps significantly increase sleep duration and quality. (1)

While our bodies produce melatonin naturally, blue light from smartphones and other devices can disrupt this process.

Supplementing with melatonin helps your brain have more of the sleeping hormone.

That said, most melatonin supplements use synthetic melatonin.

  • Performance Lab Sleep uses tart cherry extract, which is a nature-identical source of melatonin.

The same kind your pineal gland produces.

Tryptophan (500mg, TryptoPure)

L-tryptophan is an amino acid precursor to serotonin.

Serotonin is the neurotransmitter that regulates your mood and appetite, among other functions.

Your body naturally converts serotonin to melatonin when it’s time to fall asleep.

  • But if there’s not enough tryptophan available, the brain won’t be able to make melatonin. This can lead to insomnia and poor sleep quality. (2)

Performance Lab Sleep offers a patented form of tryptophan which provides your brain with the building blocks to create the sleeping hormone.

Magnesium (100mg of combined Magnesium Bisglycinate, Magnesium Taurate, and BioGenesis Magnesium)

Magnesium is an essential mineral. It helps you relax your nerves and muscles. We usually get it from our diet. But due to soil depletion and poor eating habits, many people are chronically deficient in magnesium. Magnesium deficiency is linked to restlessness, irritability, anxiety, poor memory, and yes – insomnia. (3, 4) Performance Lab Sleep provides you with 100mg of elemental magnesium to help you relax and unwind before hitting the pillow.

How to Take (Dosage)

You should take 2 capsules of Performance Lab Sleep about 1-2 hours before going to bed. If taking it on a full stomach, it’s better to take it 2 hours before bed.

If you have serious insomnia, you can safely dose up to 4 capsules per day.


  • Don’t take high doses (4+ caps) of Performance Lab Sleep if you take SSRI’s. Tryptophan, one of the ingredients in this product, increases serotonin – and so do SSRI’s. This can lead to serotonin syndrome.

Although it’s extremely unlikely that tryptophan would lead to serotonin syndrome if combined with an SSRI. It’s still smart to play it safe. Always check with your doctor first if you’re on an antidepressant.

How to Get the Most Out of Performance Lab Sleep

Taking Performance Lab Sleep alone should be enough to help you fall asleep fast once your head hits the pillow.

But to ensure optimal benefits, you should combine this supplement with a bedtime routine.

Here are a few tips:

  • Try to go to sleep at the same time every night. This helps regulate your circadian rhythm, aka, your body’s internal clock.
  • Use a sleeping mask and earplugs to block out external stimulus and improve sleep quality.
  • Avoid all electronics at least 1 hour before bed. Blue light from electronics interferes with your sleep.
  • Aim to exercise early in the day.
  • Keep the bedroom temperature cool. The body needs to cool down to fall asleep.
  • Avoid stressful activities, alcohol, and caffeine before bed as these can severely disrupt your sleep.

Side Effects

If you’re a healthy person, Performance Lab Sleep won’t cause any side effects.

It’s made from nature-identical ingredients with clinically proven doses.

That said, if you suffer from depression and take SSRI’s, it may be a good idea to talk with your doctor first. That’s because tryptophan (an ingredient found in Performance Lab Sleep) can interfere with antidepressants in rare cases.
