Thirdzy might support your nighttime routine and promote more restful sleep through its rest and recovery collagen mix. It may also help tackle common sleep-related concerns, such as trouble falling and staying asleep, frequent nighttime awakenings, and morning grogginess.
As per the manufacturer, Thirdzy could help support more deep sleep stages (REM Sleep), decrease sleep latency, and support hormone balance and recovery. It also includes collagen, which might help support muscle recovery and promote bone health.
In this review, we take a closer look at Thirdzy’s working mechanism, composition, usage instructions, and benefits. The review also explores other aspects such as refund policy, pros/cons, and the potential side effects associated with Thirdzy.
What Is Thirdzy?
Thirdzy could improve sleep quality and support overnight recovery by offering a collagen-based drink mix. It may support your body’s natural sleep cycle by targeting factors that may disrupt it, such as increased cortisol (stress hormone) levels, nighttime restlessness, and constant screen exposure.
According to the official site, one scoop (14.2g) of Thirdzy powder has 35 calories, 10,000mg of hydrolyzed collagen, 200mg of L-theanine, and 300mg of GABA. It also contains magnesium bisglycinate, sodium, calcium, and iron. Thirdzy’s magnesium content may help lower stress levels, promote calmness, and support physical and neurological recovery throughout the night.
The makers state that Thirdzy offers a melatonin-free formula, which may not trigger morning grogginess or dizziness upon waking up in the morning.
Thirdzy Ingredients
-
Magnesium
Magnesium bisglycinate may increase GABA (gamma-aminobutyric acid) activity in the brain, which may decrease neuronal excitability. Such effects may help slow brain activity and promote sleep onset. It may cross the blood–brain barrier and directly activate NMDA receptors to stimulate your parasympathetic nervous system. Such effects may support deeper and more restorative slow-wave sleep. Magnesium may also support ATP synthesis and mitochondrial function, which could help support overnight cellular repair and energy restoration. It might also help minimize muscle cramps and support muscle relaxation during rest.
-
Collagen
Thirdzy includes 10 grams of hydrolyzed collagen per scoop (14.5g) sourced from Argentinian grass-fed beef. The specific form of collagen provides essential amino acids like glycine, proline, and hydroxyproline, which may help rebuild muscle fibers, strengthen joints, and repair connective tissues.
The amino acid profile of collagen is low in tryptophan but rich in glycine and proline, which may positively influence insulin response and slow gastric emptying when taken at night. Such effects may reduce nocturnal blood sugar dips that may otherwise trigger cortisol release and cause nighttime awakenings.
-
GABA
GABA (gamma-aminobutyric acid) may work by binding to GABA-A and GABA-B receptors in the central nervous system. Such effects may reduce neuronal excitability, which could promote a calming effect on brain activity. The reduction in excitatory signals may help initiate and maintain sleep, particularly by supporting the transition into non-rapid eye movement (NREM) sleep.
GABA may also contribute to physical recovery during sleep by helping lower cortisol levels and influencing stress responses via the hypothalamic-pituitary-adrenal (HPA) axis. Lower cortisol at night may increase the activity of your parasympathetic nervous system, which may promote muscle repair, immune function, and cellular regeneration.
-
L-Theanine
L-Theanine may support relaxation and help raise the levels of neurotransmitters like serotonin and dopamine. Such effects could help quiet racing thoughts, lower anxiety levels, and support a smoother mental transition into sleep. It might also lower glutamate signaling, which may further help decrease neuronal excitability and support calmness.
L-theanine may support recovery by modulating alpha brain wave activity that may support alertness. It may also help lower cortisol levels, which could become elevated in stress or overtraining, impairing both sleep and muscle repair.
How to Use Thirdzy?
The makers suggest dissolving one scoop (14.2g) of Thirdzy powder in 2–4 oz of cold water. They highlight that there is no need for hot liquids or complicated prep. The official site also mentions drinking the mix daily, preferably 30–60 minutes before bedtime.
How Does Thirdzy Work?
Thirdzy may work to support better sleep and recovery by targeting common factors that affect rest, such as heightened nervous system activity, elevated stress hormones, and slowed muscle repair.
As per the official site, Thirdzy uses a melatonin-free formula that comprises four sleep-support ingredients, namely magnesium bisglycinate, GABA, L-theanine, and hydrolyzed collagen.
Magnesium bisglycinate and GABA are included for their potential to calm the nervous system. GABA in Thirdzy may suppress overactive neurons, lowering brain excitability and potentially reducing nighttime cortisol. Such effects could help promote relaxation and improve sleep quality.
The makers also added L-theanine to their Thirdzy formula that may cross the blood-brain barrier and increase alpha wave activity, which is related to a relaxed but wakeful mental state.
Hydrolyzed collagen present in the Thirdzy formulation may provide bioavailable peptides like glycine, proline, and hydroxyproline, which may support tissue repair during sleep by promoting fibroblast activity and collagen synthesis.
Thirdzy Benefits
-
May Support Muscle Recovery
Thirdzy may help your body rest and recover after physical activity. It supports the natural repair process that happens during sleep, which may make it easier for your muscles and joints to recover. This could lead to less soreness after workouts and help you stay active without feeling worn out. Over time, it might help you bounce back faster and feel more physically ready for your next workout.
-
Could Improve Sleep Quality
Thirdzy is intended to support a calm state before bed and steadier sleep during the night. It does not include melatonin, so it may work without altering the body’s usual sleep cycle. This could be helpful in situations when you want to avoid sleep disruptions. Improved rest may also support next-day focus and energy.
-
Might Help Support Hormone Balance
Thirdzy may play a role in supporting a healthy hormonal function by encouraging better sleep quality. Poor sleep is linked to changes in hormones related to stress, energy use, and recovery. By helping you sleep more deeply, Thirdzy could support your body’s normal hormonal rhythms without the presence of synthetic sleep ingredients like melatonin.
Thirdzy Side Effects
-
Might Cause Stomach Discomfort
Thirdzy might trigger stomach problems during the initial weeks of use. Its components, like magnesium bisglycinate, may act as a mild laxative, which might trigger diarrhea, stomach pain, or loose stools. The hydrolyzed collagen in Thirdzy may trigger bloating, gas, or a heavy feeling in your stomach, particularly if you remain dehydrated.
-
Might Trigger Nausea
Nausea may be an occasional side effect of consuming Thirdzy, possibly due to interactions with some amino acids (like glycine or proline) in the Thirdzy formulation. While amino acids like glycine help lower body temperature and promote relaxation, they might also impact digestion and blood flow. These changes may leave you with uncomfortable feelings like a fluttery sensation.
-
Could Lead To Drowsiness
Even though Thirdzy doesn’t contain melatonin, it includes ingredients like GABA, L-theanine, and magnesium bisglycinate. These compounds may slow down brain activity and trigger drowsiness, especially when you consume Thirdzy when fatigued. For some, the drowsy feeling from Thirdzy might kick in within 30–60 minutes. However, if you take Thirdzy too late at night or in situations where you need to stay awake (such as when traveling), you might feel groggy, sluggish, or too relaxed to focus.

Brand Credibility
In evaluating Thirdzy’s brand reputation, one of the first things we noticed was its relatively limited presence on authentic review forums. There is also no information about the brand’s leadership team or long-term brand history. Such a lack of brand presence may raise concerns over Thirdzy’s brand credibility.
As of now, Thirdzy does not have any presence or brand page on popular review sites like Better Business Bureau (BBB), Trustpilot, or Reviews.io, platforms that are commonly used to gauge consumer trust and satisfaction.
Meanwhile, holds a 4.0 out of 5 rating on TenereTeam. However, the rating is based on just two publicly accessible user reviews on the platform, which may significantly limit the reliability and scope of the TenereTeam ratings. Taken together, the minimal digital footprint and sparse third-party reviews may suggest that Thirdzy is still in the early stages of building its reputation.
-
Price and Value
When evaluating Thirdzy, we assessed its value in relation to the quantity provided by comparing it with two alternative products, namely Beam Dream and NooCube Sleep Upgrade. One 426g (15oz) bag of Thirdzy is priced at $72 as part of a one-time purchase. When broken down, Thirdzy’s value comes to roughly $0.17 per gram of powder, potentially making it a cost-effective option.
Meanwhile, one bag (120g) of Beam Dream costs $85, translating to a cost of about $0.71 per gram, over four times the per-gram cost of Thirdzy.
