Melatonin is a hormone found in most traditional sleep supplements that helps with sleep timing. While melatonin can assist some with falling asleep, this hormone does not directly improve sleep quality or duration.

Possible downsides of melatonin include: morning grogginess, unpleasant dreaming, dependency, and impacts on other hormones.

Because of its benefits being limited to sleep timing and its many potential downsides, we will NEVER include melatonin in our formulation.

For a supplement to help with sleep it needs to do TWO key things.

1. Help you to relax and counteract over stimulation, and

2. Support your brain chemistry and hormones for Deep and REM sleep. Thirdzy contains some of the best natural compounds to help do BOTH.

Collagen: The Relaxing Power of Glycine Collagen is made of amino acids, most of them being the glycine. Glycine is known for its calming effects on the brain. It acts as an inhibitory neurotransmitter, which helps to reduce nerve activity and promote relaxation. In studies, glycine has been shown to help lower core body temperature, which is important for deep sleep and to reduce next day fatigue.

L-Theanine: Unwind and De-stress L-Theanine is a naturally occurring compound found in green tea. It has been widely studied for its ability to counteract over-stimulation, promote relaxation, and reduce anxiety. L-Theanine increases alpha brain waves, which are associated with a state of relaxation, and REM sleep.

GABA: A Neurotransmitter for Tranquility Gamma-Aminobutyric acid (GABA) is a neurotransmitter that plays a crucial role in promoting relaxation and sleep. By inhibiting nerve activity in the brain, GABA helps to quiet the mind and prepare it for deep, uninterrupted sleep.

Magnesium: The Mineral for Relaxation Magnesium is an essential mineral involved in over 300 biochemical reactions in the body. It plays a significant role in muscle relaxation and the regulation of the sleep-wake cycle by supporting your natural production of melatonin.

For best results, take it 30-60 minutes before bed. Experiment with the amount of water you dissolve it in. Using more water will mellow the flavor and it will dissolve more quickly.

Thirdzy was formulated to be used nightly. And our customers that use it very consistently see the greatest improvements to their sleep quality.

Many people notice a difference from the very first night. The L-theanine and GABA have a gentle calming effect that starts to become noticeable within 20 to 40 minutes.

Most people find that with consistent, ongoing use, the quality of their rest and recovery continue to improve for many weeks. For people who are deficient in magnesium, there is a loading phase to reach ideal levels in the body.

Joint and muscle building benefits from collagen can become very noticeable after 4 to 12 weeks of use, but the anti-inflammatory effects of the collagen can provide noticeable improvements in soreness sooner.

Thirdzy contains ingredients, dosed in clinically relevant amounts. This means that we use amounts that have been shown in scientific studies to promote sleep and improve sleep quality.

However, every sleep challenge is unique to the sleeper. Our products are made to support better sleep quality and recovery, but are not intended to treat or cure any disease or pathology. If you suffer from or have been diagnosed with any medical condition, or are taking any medication we recommend you talk to your doctor about your best options.

Besides helping with sleep quality, the collagen and magnesium in Thirdzy support the natural regeneration processes throughout your body following physical activity. Their benefits include joint and bone health, improved muscle recovery, hydration, electrolyte balance, reduced fine lines and wrinkles, and even healthier skin, hair, and nails. 

In addition to the active ingredients, our non active ingredients are: 

• Malic acid + Natural flavors (to make it taste yummy)
• Stevia leaf extract (for a bit of sweetness)
• Silicon dioxide (to prevent clumping)
• Beet root powder (for color)

No! Thirdzy is all natural and does not lead to dependency. 

It does not contain melatonin, so it does not replace your own production of sleep hormones.

It can be used as often as needed without stress about getting hooked. You won’t suffer or have any kind of withdrawal if you miss a night.

In fact, some people report that since starting to use it their sleep is noticeably better even on the nights that they forget to take it. This is because many of the ingredients work systemically, not just right before bedtime.

Yes! Even if you are already a pretty strong sleeper, the functional ingredients in Thirdzy will provide your body with nutrients that it will use to support better repair and recovery of your joints, muscles, ligaments, tendons, and bones. The magnesium, L-theanine and GABA also help calm your nervous system for better recovery scores on your sleep trackers and even support hydration and electrolyte balance.

Maybe. Your changing hormones during menopause can have a big effect on many of your body’s processes, including sleep. But these hormonal changes and effects are complex. And since every person is unique, we cannot promise that Thirdzy will "fix" your sleep. But many menopausal and perimenopausal women have used our product and found it very helpful.

Unfortunately there aren't enough studies done with our ingredients during pregnancy for us to say that it's a safe option. 

You can double check with your primary health care practitioner. They may have experience seeing pregnant clients using these ingredients safely.

It depends on how much of a purest you are around fasting. Some people will say that anything other than water isn't fasting.

However, if you're fasting because you're trying to get the metabolic benefits of not having fluctuations in your blood sugar and insulin levels, then 1 scoop of Thirdzy is going to have very little impact on your fast. There is no sugar and only 9g of protein (in the 10g of collagen) - which is not enough to push your body out of a metabolically fasting state. 

We do not recommend using Thirdzy while under the influence of alcohol or other drugs.

While having a drink with dinner and then taking your Thirdzy is very unlikely to be a problem. Your liver processes both natural supplements and alcohol (as well as other over the counter and pharmaceutical substances). Having any combination of substances in your blood will slow down their metabolism, increasing the time that they are in your body.

Alcohol also exerts significant negative effects on your sleep quality – particularly REM sleep – that will counter the positive benefits of Thirdzy.

The 'consult a health care provider for use beyond 4 weeks' statement is something that Health Canada requires. Nearly all supplements - even mutivitamins and minerals, in Canada have some form of 'consult a health practitioner for use beyond x timeframe.' 

There is not a specific reason for the 4 week timeline - none of the ingredients show negative effects after use of longer durations. In fact, many of the studies on the ingredients use intervention timelines of 12 weeks. 

Yes! Every batch of product is third party tested and certified by Informed Sport. They test to confirm both our levels of active ingredients and the purity of our product – including for over 250 substances that are banned in sports/competition. Our product is safe for athletes competing at all levels.
