We have some BIG NEWS to share! Whether you’ve been a long-time customer or have been thinking about pulling the trigger on your first order – you’re going to want to hear this: We have made some big changes to our PM Recovery Collagen!


Before we get into the nitty-gritty of what we’ve changed: Rest assured – if you’ve been using and loving the product already – this is NOT going to make it less effective for you. All of the changes are for the better and will make PM Recovery Collagen an even better support for your sleep and recovery every night!


Here are the specific upgrades:

1. Trust - Introducing Informed Sport Certification

PM Recovery Collagen
We are proud to announce that every batch of PM Recovery Collagen that we produce will now be Informed Sport Certified!

What that means:

You can trust our product even more now :)

Informed Sport is a global quality assurance and supplement certification program for sports supplements. The Informed Sport Certification demonstrates that every batch of a product has been tested for more than 250 substances prohibited in sport and that the product was made in an environment with quality systems appropriate for the stringent demands of sports nutrition manufacturing.

Why you can be pumped about it:

This is a seal of assurance – from an impartial 3rd party – that there are no nasties or contaminants in our product. The testing also confirms our label claims (that what we say is in the product IS in there, in the amounts that we say are in there).


If you compete at any level of sport that requires banned substance testing, you can use our stuff without worrying that you might be taking something that could get you disqualified. No Informed Sport certified product has ever caused an athlete to be banned from competition. 

*Pretty solid track record*

2. Effectiveness - Upgrade to Magnesium Bisglycinate

We have upgraded the type of magnesium we are using from Magnesium Citrate to Magnesium Bisglycinate


What that means:

There are tons of different forms of magnesium. When you take a magnesium

supplement, you are never taking pure magnesium. It needs to be bound to 

other compounds to be safe for consumption and to be properly absorbed in 

your system.


These carrier molecules are often amino acids (like tiny protein building 

blocks) which can affect how the magnesium is absorbed, where it goes in 

your body, and how it gets used.


Magnesium Citrate is a commonly used form of magnesium. It is very safe for consumption and is easy absorbed in the gut. It is a small molecule, meaning you can get a good dose of magnesium in a smaller volume of supplement, and it is very cost effective. One downside to magnesium citrate is that some people get a laxative effect from it if they take too much at once – but this can be helpful for people who suffer from constipation.


Magnesium Bisglycinate (aka Magnesium Glycinate) is magnesium combined with the amino acid glycine. Research has shown that magnesium glycinate is one of the best absorbed forms of magnesium and tends to have better tissue uptake (use in your body) than other forms of magnesium. It is also very gentle on the gut and is unlikely to cause loose stools.


The other upside to magnesium glycinate is the glycine. Glycine works alongside other chemicals in your brain, like GABA, to help calm and de-stimulate your brain. In technical terms, it can function as an ‘inhibitory neurotransmitter’.  Glycine has also been shown to improve sleep quality. It’s one of the reasons we include the collagen in our product – because collagen is about one third glycine.


The downside (and reason why we didn’t use magnesium glycinate before) is that it is a very large molecule. By weight, magnesium bisglycinate is only about 14% magnesium – which means you need a HEFTY dose of it to get enough magnesium to meet your needs.


So to hit our effective dose of magnesium (250 mg), it requires a 1772 mg (or 1.7g) serving of magnesium bisglycinate!


Since we have made the switch, you will also notice (if you are very detail oriented) that our serving size has increased. Each scoop used to be 13.5 grams and is now 14.2 grams.


Why you should be pumped about it:

The switch to magnesium bisglycinate adds even more fuel for amazing sleep and recovery. You’re getting just as much magnesium as before, in a more useable format. Plus, even more of the added relaxation and rest supporting effects of glycine.               

3. Taste - Enhanced Flavor Experience

We have taken a ton of customer feedback around the flavor and have worked on making our Strawberry Lemonade flavor milder and more ‘relaxed.’


If you are a huge fan of the existing flavor – we really hope you’ll love the updated flavor just as much. We have stayed in the same profile (strawberry lemonade) since fruity and sour flavors work the best with our active ingredients to balance any bitter or medicinal flavors. We have just taken down the intensity of the flavor (and color) to try to have a more relaxed, before bed vibe.


During the formulation process, we had sent samples of the new flavor to many existing customers and received very positive feedback. And our co-founders' kids were even fighting over the last drop of the new flavor, so we're confident that you will love it too!


And finally, in addition to the new flavor, you'll notice that the upgraded PM Recovery Collagen dissolves even easier than our existing formulation! 

4. Price Change

We’re increasing the price of our 30 serving bags of PM Recovery Collagen in the U.S. by $4 (or 13 cents per serving). Canadian launch of the new formulation and pricing will follow in a few months.


Nobody likes to pay more for the same thing. And over the past couple years of prices escalating on nearly everything, Thirdzy has succeeded in keeping our prices FLAT by absorbing cost increases across our supply chain.


Now, instead of a price increase without giving you more, we've enhanced the trust you can place in our product, improved its effectiveness, and made it even tastier and easier to dissolve. We're confident that even with the price increase, these improvements make PM Recovery Collagen better value!


Price increase will be effective on October 1st, 2023.

If you are already on subscription with us, your existing price will be locked in for the lifetime of your existing subscription. (And remember that you can pause, skip, and change the delivery frequency of your subscription products at any time!). 


We are also giving all our customers the chance to buy and try the new product at the existing price point until October 1st.


We are so thrilled to bring you these changes. As a company, we are striving to always do better, and these changes reflect our commitment to supporting athletes in getting their best possible sleep and recovery.


We would love your feedback (zteam@thirdzy.com) after trying this upgraded version of the product.


Thank you so much for trusting your sleep and recovery to Thirdzy!


Sleep tight,
Dr. Justine
