Thirdzy Rest & Recover Collagen Sleep Aid Updates

We have some big news to share! Whether you’re a longtime 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 melatonin free sleep aid, including a new name!

Our PM Recovery Collagen is now Rest & Recover Collagen, but it still harnesses the power of glycine, L-theanine, GABA, and magnesium in carefully researched amounts to help you improve your sleep quality and support your body as it recovers each night.

But 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 Rest & Recover Collagen an even better support for your sleep and recovery every night!

Let’s take a closer look at the specific updates.

1. Rest & Recover Collagen Is Now Informed Sport Certified

We are proud to announce that every batch of our Rest & Recover Collagen sleep aid is now Informed Sport Certified!

What’s Informed Sport Certification?

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 undergone testing for more than 250 prohibited substances. It also confirms the manufacturing environment has quality systems in place that are appropriate for the stringent demands of sports nutrition manufacturing.

Benefits of Informed Sport Certification

This is a seal of assurance from an impartial third party that there are no contaminants in the sleep supplements you’ve just purchased. The testing also confirms the claims on the label of every Rest & Recover Collagen product — that what we say is in the product really is in there, and in the amounts we’ve cited.

In other words, 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. That’s a pretty solid track record, wouldn’t you say?

2. Rest & Recover Collagen Has Gotten a Magnesium Upgrade

Our Rest & Recover Collagen has always been a melatonin-free sleep aid since research has shown melatonin can affect your hormones and metabolism. Our collagen sleep aid relies instead on magnesium, L-theanine, glycine, and GABA to foster high-quality sleep. 

But today we’re announcing the switch from magnesium citrate to magnesium bisglycinate. Why the change? Let us elaborate.

Magnesium Bisglycinate vs. Magnesium Citrate

Magnesium bisglycinate, aka magnesium glycinate, is magnesium combined with the amino acid glycine. Research has shown that the gut can easily absorb magnesium glycinate, it’s very gentle on the gut, and it tends to have better tissue uptake (use in your body) than other forms of magnesium. Unlike magnesium citrate, magnesium glycinate is unlikely to cause loose stools.

Magnesium citrate is another common form of magnesium that’s safe for consumption and highly absorbable. It’s a small molecule, meaning you can get a good dose of magnesium in a smaller volume of supplement, making it generally very cost-effective. Although the laxative effect it produces in people who take too much at once can help relieve constipation, the loose stools are generally a downside and something you don’t have to contend with if your supplement features magnesium bisglycinate instead.

Why Are There Multiple Forms of Magnesium?

There are many different forms of magnesium out there. When you take a magnesium supplement, you are never taking pure magnesium. This is because, in order for magnesium to be safe for consumption and for your body to be able to properly absorb it, magnesium has to bind to other compounds. These other compounds, also called carrier molecules, affect how your body absorbs the magnesium, where it goes, and how your body uses it.

What’s So Great About Glycine?

Magnesium bisglycinate features glycine, which we see as a major advantage. Glycine works alongside other chemicals in your brain, like GABA (a neurotransmitter that helps with stress reduction), to help calm and de-stimulate your brain. Studies have shown that glycine can even improve sleep quality. For this reason we include collagen, which is about one-third glycine, in our Rest & Recover Collagen sleep supplement.

All About the New Serving Size

Since we’ve made the switch to magnesium bisglycinate in our collagen sleep aid, our serving size has increased: Each scoop used to be 13.5 grams but is now 14.2 grams. This is because magnesium bisglycinate is a very large molecule, and by weight, it’s only about 14% magnesium.

As a result, you need 1,772 mg (or 1.7 g) of magnesium bisglycinate to get 250 mg of magnesium, which is what we consider an effective dose of magnesium. Rest assured, you’re getting just as much magnesium as before, but now in a more usable format and with additional relaxation benefits. And as a bonus, you might notice the upgraded Rest & Recover Collagen dissolves even easier now, too.

3. Rest & Recover Collagen Now Features Even Better Flavor

You shared your feedback about the flavor, and we listened. Now our Strawberry Lemonade flavor is milder and more “relaxed.”

If you’re a huge fan of the existing flavor, we believe you’ll love the updated flavor just as much. We stayed in the same flavor profile (strawberry lemonade) since fruity and sour flavors work best with our active ingredients to balance any bitter or medicinal flavors. We just took down the intensity of the flavor (and color) to try to have a better “right before bed” vibe.

We’ve been so happy to have already received very positive feedback from many existing customers about the updated flavor (our co-founders’ kids were even fighting over the last drop!), and we know you’ll love it, too.

4. New Pricing Reflects the New Improvements

First, the downside: We’re increasing the U.S. price of our 30-serving bags of Rest & Recover Collagen by $4 (or 13 cents per serving). In Canada, the launch of the new formulation and new pricing will follow in a few months.

We know that nobody likes to pay more for the same thing. Over the past couple years, as the price of nearly everything has escalated, we’ve succeeded in keeping our prices flat by absorbing cost increases across our supply chain. However, making the new enhancements described above meant it was time to re-price the product according to its value.

Which brings us to the upside: Rest & Recover Collagen offers you better value now than ever before. Instead of increasing the price without giving you something more, we’ve leveled up the product to be the very best in its class.

• Every package is now Informed Sport Certified, increasing the trust you can place in our product. 

• We improved the product’s effectiveness, incorporating a form of magnesium that’s gentler on your gut with even better calming benefits.

• And we made the product even tastier and easier to dissolve, ensuring you have a pleasant experience from start to finish.

Our goal was to bring even better value to your sleep stack with every package of our Rest & Recover Collagen sleep aid — and to make the product an absolute standout among the competition. We believe we’ve done that and are confident that once you give it a try, you’ll believe it, too!

This new pricing goes into effect on October 1, 2023. If you already have a 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 so thrilled to bring you these updates. As a company, we are always striving to do better, and these changes reflect our commitment to supporting athletes in experiencing their best possible sleep and recovery.

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

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

Sleep tight,

Dr. Justine Luchini
