EAA Sleep Ingredients

Primeval Labs has included a quartet of effective relaxation/sleep aids to help you race off to dreamland and get a better night’s rest. As you probably figured out, there’s also a full complement of essential amino acids to support muscle and tissue repair while you get some much needed shut eye.

  • Sleep Aid

    • GABA (1g)

      Primeval Labs EAA Sleep Ingredients

      EAA Sleep contains the same amount of EAAs found in EAA Max along with a quartet of proven supplements to help you sleep peacefully each and every night.

      Leading off the sleep aid complex of EAA Sleep is GABA, the primary “downer” neurotransmitter. GABA has been implicated in several sleep mechanisms including dreaming, REM sleep, and waking up.[1,2]

      It’s important to note that supplemental GABA cannot cross the blood-brain barrier, yet it does enhance one’s sleep by increasing alpha waves and decreasing beta waves in the brain.[3] This is beneficial for sleep as alpha waves are the deep relaxation waves, whereas beta waves are the “awake” or “conscious” waves.

      GABA serves as a natural relaxant, and its effects are felt typically within one hour of consuming it.[4] It also may provide a modicum of pain relief too.[5]

    • L-Theanine (200mg)

      L-Theanine is no stranger to relaxation/sleep aids. This amino acid present in tea leaves promotes a sense of calm and induces relaxation in individuals.[6,7] The dose here is strong enough to certainly chill you out and help you brush away the anxiety/stress that can tend to interfere with sleep.

    • 5-HTP (100mg)

      5-HTP, short for 5-hydroxytryptophan, is a precursor to serotonin, the neurotransmitter most commonly associated euphoria. It’s derived from the essential amino acid tryptophan (also included in EAA Sleep), and then converts to serotonin.

      Despite the euphoric properties of 5-HTP, it’s also commonly used in sleep aids. Studies have commonly combined 5-HTP with GABA or valerian and found subjects experienced better sleep quality and a quicker time to fall asleep.[8]

    • Melatonin (2.5mg)

      Melatonin Benefits

      Melatonin supplementation improves QOS (quality of sleep) and has a relatively high response rate, even at 2mg.

      Any sleep formula worth its salt has to have melatonin!

      Melatonin is a naturally-occurring hormone generated during various times of the day that helps to normalize sleep patterns. It’s been shown numerous times to help individuals fall asleep and improve sleep quality.[9,10,11]

      The “trick” with melatonin is the dosing, more isn’t always better, as studies have shown supplemental melatonin can be successful from 0.5mg up to 10mg.[12,13] 2.5mg is right in the sweet spot for most people.

  • BCAAs 2:1:1 (5g)

    For the amino acid portion of EAA Sleep, Primeval Labs leads it off with a stout 5g dose of 2:1:1 BCAAs, supplying your body with 2.5g of Leucine, 1.25g of Isoleucine, and 1.25g of Valine.

    Leucine is primary catalyst that activates the mTOR pathway in the body[14], keeping muscle growth and repair running while you get some much needed shut eye. Additionally, BCAA consumption enhances recovery and may prevent excessive muscle soreness.[15,16]

  • EAAs (820mg)

    Primeval Labs has carried over the exact same essential amino acid profile from EAA Max, so pop on over there if you want the full rundown of what each individual amino acid does. For reference, here’s the list of each EAA amount should you be interested:

    EAA Max StephFitMum

    Primeval has carried over their “secret sauce” of EAA Max to EAA Sleep, helping to keep you fit and ripped like StephFitMum.

    • L-Lysine HCl (300mg)
    • L-Threonine (225mg)
    • L-Phenylalanine (200mg)
    • L-Tryptophan (50mg)
    • L-Histidine (25mg)
    • L-Methionine (20mg)

As we mentioned up top, including all the EAAs provides the essential building blocks your body needs for muscle and tissue repair during the night, which is when the body does the vast majority of its recovery.

Flavors Available

We’ve stated it before, and we’ll continue to state it now — Primeval Labs has some of the best flavoring in the industry, so expect EAA Sleep to taste absolutely phenomenal. The brand has launched their new sleep aid in two flavors: Tropical Lemonade and Pineapple Mango.

Takeaway: EAAs come to Sleep Aids

Primeval Labs

Primeval Labs continues to deliver stellar new releases, what’s up next for the brand?!

Sleep is one of the most underappreciated/underemphasized facets of health, cognitive function, and muscle growth. Far too often, sleep is brushed aside as something only fitting for infants and elderly folks. Well, that’s just not the case. EVERYONE needs sleep, and if you’re struggling to get quality sleep each night, EAA Sleep can help!

With Primeval Labs bringing EAAs back into the fold, it was only a matter of time before more sleep and recovery aids used it! They use more of a sleep “compound” route, using trusted single-ingredient compounds, and not going with any herbals that are tough to get consistent.

So don’t brush off sleep anymore, that is unless you like feeling miserable all the time. With the mix of mood- and sleep-enhancers, Team Primeval‘s got you covered.
