Researchers Reveal A Strange  "Rogue Protein" Causing Achy Joints

And It Has Nothing To Do With Wear and Tear or Aging

Hi there, I’m Dr. Blake Myers, joint-health expert with over 10 years experience.

And today, I'm going to reveal a shockingly effective Joint Guardian Technique...

Plus a twist you won't see coming… Disclosing the REAL culprit behind relentless joint agony.

One single, out-of-control protein.

This seemingly innocent protein, designed to renew our tissues, is in reality a wolf in sheep's clothing! 

As we age it morphs into an invisible, relentless pac-man, eating away at your cartilage.

Scholars worldwide are flabbergasted.

But a groundbreaking discovery backed by top scientific research from organizations like the National Institute of Health…

Effortlessly restores your mobility with smooth, comfortable movements...

And repairs damaged cartilage, stimulating its growth and keeping your bones healthy...

sect-1

All so you can regain your independence and perform daily activities without pain or worry…

sect-1

Just imagine being able to get up from your favorite chair without wincing in pain…

sect-1

Or enjoying a leisurely walk holding hands with your spouse…

sect-1

And reclaiming your favorite hobbies and activities, like pickleball, gardening, golf, or playing with your grandkids…

Activities you never thought you’d get back to…

Without feeling held back by your aching joints.

Now, I know these may sound like bold promises...

But I'm 100% confident standing behind these promises …

Because I’ve seen firsthand how blocking this single protein transforms lives…

It worked wonders for my own father...

And has transformed the lives of over 32,000 men and women aged 50 and above...

Former prisoners of their own bodies now living vibrant, active lives on their terms, joint pain a distant memory...

About Dr. Blake:

I’m a licensed naturopathic doctor, graduate of Bastyr University, and author of “The Natural Apothecary,”

The Real Culprit Behind Achy Joints

Most joint-pain treatments, like over-the-counter pain relievers, injections and even prescription medications, never truly address the root cause of our aches and pains…

Because they only provide temporary relief and don't target the real culprit behind our joint discomfort…

And if you're wondering WHY our joints become so painful as we age…

The usual suspects like wear and tear and inflammation might play a small role…

But the REAL problem is something much more shocking…

Something nobody is talking about, even though it's right under our nose.

It’s called Matrix Metalloproteinase (MMP).

MMPs are a family of helper proteins that have an important job - they break down and reshape the matrix.

The matrix is all the stuff between our cells, kind of like the mortar between bricks. This includes proteins like collagen, enzymes, and other molecules. 

The matrix gives our tissues form and structure.

There are actually many types of MMPs, each with slightly different jobs. 

MMP-13 is one of them. MMP-13 is specialized to break down collagen, the main protein that makes up connective tissues like tendons, ligaments, and cartilage.

All MMPs start off folded up and inactive, like a closed pocket knife. This helps keep them under control. 

When MMPs are needed, other proteins unfold and activate them, kind of like opening up the pocket knife to expose the blade. 

Once activated, MMPs can start breaking down matrix proteins. They reshape the matrix a little at a time - cutting here, reforming there. 

This recycling keeps our tissues healthy.

Unfolding the Shocking Truth;
Out-Of-Control Cartilage Breakdown

Problems happen if MMPs get overactivated. It's like an open pocket knife flailing around! 

This can lead to too much of the matrix proteins getting cut. 

For MMP-13, too much collagen breakdown damages cartilage and leads to joint stiffness and pain.

MMP-13 is the specific protein that predominates in our articular cartilage…

Articular cartilage is a smooth, white tissue that lines the ends of bones where they form joints. 

It's a living tissue that helps bones glide smoothly over each other with minimal friction.

sect-1

Articular cartilage's main functions include:

sect-1

Cushioning

sect-1

Lubricating

sect-1

Shock Absorption

Studies have shown that MMP-13 levels start to rise in joint cartilage as we reach our 40s and 50s. 

At the same time, our bodies start making less of the natural inhibitors that normally shut off MMP-13 activity. 

This imbalance leads to innocent protein going rogue...

It becomes a relentless, cartilage-gobbling monster…

Turning our once-strong, flexible joints into achy, painful shadows of their former selves.

So it’s no wonder traditional methods for dealing with joint pain don't offer more than temporary relief.

sect-1

And without that cushion, our bones start to rub against each other...

Causing the searing pain we experience each day.

Isn't that mind-blowing?

But don't lose hope just yet…

There is a breakthrough so significant that leading scientific journals can't stop raving about it. 

Studies from institutions like PubMed, Wiley Online Library, and ScienceDirect all concur…

That it’s a way to regain control of our lives and finally put an end to insufferable joint pain.

Fighting Back Naturally

And relieving joint pain and regaining mobility is much simpler than most people think...

In fact, it's entirely natural and doesn't cost a fortune.

And once we understand the real cause of joint pain (which is this MMP protein going haywire) we can actually tackle the problem at its root.

The key to getting rid of joint pain and ing our freedom and independence...

Is to simply block and inhibit out-of-control MMP protein.

And that’s the secret behind the incredible results of my father and my patients.

They not only experienced a significant reduction in joint pain, but also regained their mobility, energy, and zest for life.

And the best part?

The entire solution comes down to a combination of natural extracts and compounds...

Each of which has been proven in multiple scientific studies to effectively block and inhibit the MMP protein…

So you too can start experiencing the life-changing benefits for yourself as soon as possible.

Flavonoid Phenomenon

The first incredible compound is Quercetin...

This naturally-occurring flavonoid is found in many fruits and vegetables, like apples, onions, and berries...

And it's been known for its powerful anti-inflammatory and antioxidant properties.

But what really makes Quercetin stand out is its ability to
target that pesky protein Matrix Metalloproteinase (MMP)...


As you already know, MMP is responsible for breaking down our cartilage and causing joint pain...

But Quercetin can help regulate MMP activity, ensuring that it doesn't go into overdrive and cause more damage than necessary.

There is a ton of astonishing research to back up these claims...

sect-1

One study published in the Journal of Cellular and Molecular Medicine showed that Quercetin could significantly reduce MMP production and activity in joint tissue...

This means that it can directly address the root cause of joint pain by preventing excessive cartilage breakdown.

Another study from the Journal of Free Radical Biology and Medicine...

Found that Quercetin could reduce inflammation and oxidative stress in joint tissue...

Both of which are major contributors to joint pain and arthritis.

And it doesn't stop there...

Yet another study, published in the journal Molecules...

Demonstrated that Quercetin could protect joint cartilage from degradation by inhibiting the production of inflammatory molecules...

Helping to maintain the integrity of our joints and keep them healthy.

It's truly remarkable! But this is just one amazing ingredient that can help with your joint pain...

Himalayan Gold for Cartilage

The next one is an incredible herb called Boswellia, which has been used for centuries in Ayurvedic medicine. 

Boswellia is actually a type of tree resin that's native to the dry regions of India, Africa, and the Middle East.

What makes Boswellia so special is that it contains a unique compound called AKBA, which stands for Acetyl-11-keto-β-boswellic acid. 

This powerful compound has been proven to directly target and inhibit the MMP protein that's responsible for breaking down too much cartilage in our joints as we age.

In one study published in the Journal of Inflammation Research, scientists took a group of participants suffering from joint pain and gave half of them a Boswellia extract containing a high concentration of AKBA, while the other half received a placebo.

The results were astonishing!

sect-1

The group who took the Boswellia extract saw a significant reduction in their joint pain and inflammation, while the placebo group showed no improvements.

The researchers concluded that the AKBA in Boswellia was directly responsible for these amazing results, as it effectively inhibited the MMP protein and prevented further cartilage breakdown.

But that's not all... 

In another study, from the Journal of Ethnopharmacology, scientists found that participants who took Boswellia extract experienced a 46% reduction in joint pain, as well as significant improvement in their overall joint function.

Can you imagine how life-changing this could be? 

By taking Boswellia, which directly targets the MMP protein, we could finally regain our mobility, independence, and quality of life. 

No more feeling like prisoners in our own bodies, and no more missing out on precious moments with our loved ones.

A Legendary Ancient Spice

The next ingredient is a powerful spice that has been used for centuries in traditional medicine for its potent anti-inflammatory properties…

And science reveals how this fiery orange spice can help reverse age-related cartilage breakdown.

It’s all thanks to a unique compound called curcumin, which is found inside turmeric…

Curcumin has been scientifically proven to:

Inhibit the overactive MMP protein...

Reduce inflammation in our joints...

And even help rebuild damaged cartilage!


In fact, one study from the National Library of Medicine, where adults with arthritis took a curcumin supplement regularly...

Saw their joint pain and swelling significantly decrease…

sect-1

The study concluded that curcumin's effects were comparable to those of conventional anti-inflammatory drugs!

Another study published in the Journal of Clinical Immunology found that curcumin effectively reduced inflammation and pain in people with rheumatoid arthritis…

And it did so without any adverse side effects!

And a 2023 research article published in Frontiers in Immunology…

Discovered that curcumin not only reduced joint inflammation…

But it also helped prevent cartilage breakdown by regulating the MMP protein!

So, just imagine the powerful combination of Quercetin, Boswellia, and Turmeric…

sect-1

All working together inside your body…

Targeting the root cause of your joint pain by addressing the overactive MMP protein…

Helping to rebuild damaged cartilage and reduce inflammation…

Allowing you to regain your mobility, independence, and quality of life…

How much would your life change if you could finally enjoy activities you once loved…

And keep up with your grandkids and family without any pain?

The possibilities are truly amazing…

But this unique blend also included:

The Tropical Enzyme Breakthrough

A powerful dose of Bromelain, extracted from the core of the pineapple...

Is truly remarkable because...

Research has shown that Bromelain has strong anti-inflammatory properties and can help reduce joint pain and swelling...

One study even found that Bromelain was as effective as the prescription drug diclofenac in reducing pain in patients with osteoarthritis...

And another study published in the Journal of Clinical Rheumatology showed that Bromelain can significantly improve joint pain and function...

It's amazing what nature can provide!

sect-1

The Organic Joint Saver Your Joints are Starving For But Can't Produce On Their Own

sect-1

And to really make the Joint Guardian complete Methylsulfonylmethane, or MSM for short, was also included.

You see, this organic sulfur compound is found in certain plants, and it's known for its ability to improve joint flexibility and reduce pain and inflammation...

A clinical trial published in the Journal of the International Society of Sports Nutrition even showed that MSM can help reduce muscle damage and joint pain after intense exercise...

And another study found that MSM can enhance the production of substances that protect your joints, like hyaluronic acid and type-II collagen...

Imagine being able to move freely, without pain, and enjoy your favorite activities again!

The Essential Amino Acid for Flexibility

Then there’s the incredible power of Methionine...

An essential amino acid that our body can't produce on its own...

It turns out that Methionine can help reduce inflammation and promote the growth of new, healthy cartilage in our joints...

A study published in the Journal of Anatomy found that Methionine can significantly improve cartilage health and function...

And another study showed that it can even help protect our
joints from the damaging effects of arthritis...


Imagine feeling strong and resilient, with joints that can withstand the test of time!

sect-1

Cartilage-Protecting Compounds

And, finally, two natural compounds that are known for their ability to support cartilage health and reduce joint pain... Glucosamine and Chondroitin.

In fact, they are the building blocks of healthy cartilage.

This is what your body naturally uses to form the cushioning in your joints.

Research has shown that, when taken together, they can be even more effective at improving joint function and reducing pain than when taken separately...

sect-1

A study published in the Journal of Orthopaedic Surgery and Research found that Glucosamine and Chondroitin can significantly improve pain and function in patients with knee osteoarthritis...

And the National Center for Complementary and Integrative Health even states that these two compounds can help slow the progression of joint damage in people with osteoarthritis...

So there you have it...

These amazing, natural ingredients can work together to help you regain control of your life, reduce joint pain, and improve your overall quality of life.
