Scientists Shocked: Groundbreaking Antioxidant 6,000x More Potent Than Vitamin C

We need antioxidants now more than ever to fight back against toxins, pollution, processed foods and more.
Could this be our savior?

The older you get, the more critical it becomes to protect your brain, heart, eyes and other critical organs from free radicals. These toxic renegade molecules are working hard to damage your cells, create body-wide inflammation and make you feel older, faster.

In fact, the damage caused by free radicals is one of the most significant factors that perpetuates the array of health issues that bring people into my clinics, desperate for help.

Durable HEART

That’s because these free radicals literally accelerate the aging process, preventing you from feeling your best now and setting you up for an array of serious health issues later in life.

Hello, I'm Dr. Kevin Passero. Please keep reading because I’m going to teach you how to take advantage of a groundbreaking antioxidant that can create a natural "shield" for your body and protect it from not only damaging free radicals, but also the oxidative stress and inflammation that may be the culprit behind your nagging health issues.

By Far the Most Potent Antioxidant on Earth

Data from leading laboratories around the world has shown this incredible antioxidant to be 6,000 times more potent than the venerable Vitamin C—known for decades to be one of the most powerful and health-giving antioxidants available.* 

The very same data shows this unique antioxidant to be 560 times more potent than green tea; 800 times more potent than CoQ10; and even 3,000 times more powerful than resveratrol, offering you the highest level of protection for your brain, heart, eyes, skin and entire body.*

In fact, when you line up all of the world's most powerful antioxidants, nothing comes close to this antioxidant's potency. In my 20+ years of treating patients, I've never seen anything like it. 

If You’re Going to Take One Antioxidant for Cellular Protection This Should Be It

Earlier I called this antioxidant one of the most powerful on earth. I don’t throw that phrase around lightly, and you’re about to learn why.

The antioxidant I’m talking about is a unique carotenoid called Astaxanthin, found naturally in microalgae, and its sheer potency is unlike any other antioxidant yet discovered.

The benefits of shielding your body using this incredible antioxidant will give you:

✔ A Stronger, Better Working Heart
✔ Sharper Memory & Mental Clarity
✔ Protection for Your Vision
✔ Pain-Free Joints & Improved Flexibility
✔ Boosted Energy, Strength & Endurance
✔ Optimized Immune Health
✔ More Youthful Looking Skin

Durable SHIELD

Why You Need a Solid Antioxidant Defense Strategy for Healthy Aging

As I mentioned above, the oxidative stress that is so harmful to your body is caused by free radicals, and this invisible threat can be the deciding factor between whether you age faster than expected or look and feel great as the years go by.

A healthy diet in conjunction with your body’s natural “built-in” antioxidant defenses can only neutralize low levels of free radicals.

Unfortunately, pollution, processed foods, pesticides, chemical exposure and pharmaceutical drugs combined with our hectic 24/7 modern lifestyle all work together to generate an excess of free radicals that can overwhelm our natural defenses.

This is where Astaxanthin comes to the rescue, neutralizing free radicals, stopping oxidative stress dead in its tracks, and creating a potent shield of protection for every cell in your body.*

What makes Astaxanthin so much more effective than other antioxidants like vitamin C? It has the unique and remarkable ability to go where other antioxidants can't, penetrating and armoring every cell, tissue and organ in your body.*

The Miracle of Astaxanthin's Health-Giving Properties Revealed

As you can imagine, maintaining your cell membrane integrity is critical for cellular health and function, and no antioxidant does it better than Astaxanthin.

That’s because, according to a 2019 report by doctors writing in Oxidative Medicine and Cellular Longevity, it penetrates the bilayer phospholipid membrane of every cell in your body and uniquely protects it from the inside out.*

Once inside your cells, Astaxanthin's benefits really start to kick into overdrive.

Astaxanthin Protects and Replenishes Cell Mitochondria and This Is Crucial to Aging Well

Mitochondria are the “power plants” inside every cell. They produce the energy that fuels everything you do.

And now scientists say it’s where aging begins, because oxidative stress breaks down your mitochondria. 

Thankfully, Astaxanthin combats this breakdown.

A study from Japan confirms that Astaxanthin not only protects mitochondria from oxidative stress but is also “effective in improving mitochondrial function.”*

That’s great news for those who want to fight back against aging and for those who want to enjoy more energy every day.

Astaxanthin’s next “health miracle” will be most important to you if your biggest concern is staying mentally sharp.

Astaxanthin Is One of the Few Antioxidants
That Boosts Your Brain and Memory

The blood-brain barrier is a unique layer of cells in your brain’s blood vessels that determines what can and what can’t get through.

Astaxanthin is one of the few antioxidants that gets the “green light.” This is critical since the brain has some of the highest levels of oxidative stress in the body which is associated with age-related cognitive decline.

Neurosurgeons writing in GeroScience cite over 90 studies to confirm Astaxanthin as “a useful compound in delaying or ameliorating cognitive impairment associated with normal aging.”*

And this kind of expert medical confirmation of Astaxanthin’s power is happening all over the world.

Medical Specialists in So Many Fields Test Astaxanthin…and Come Away Impressed

Like the neurosurgeons I mentioned above, doctors in other fields have also been won over by Astaxanthin’s amazing benefits:

✔ Aging Specialists at the acclaimed Juntendo University School of Medicine report how it helped older adults with age-related forgetfulness improve their cognitive scores significantly after taking 12 mg daily for 12 weeks.*

Cardiovascular Experts determined that 12 mg of Astaxanthin taken daily resulted in reduced triglycerides and increased “good” HDL cholesterol in a 12-week hospital study.*

Blood Sugar Specialists at Japan’s highly-regarded Kamiichi General Hospital showed how 12 mg of Astaxanthin taken daily helped improve glucose metabolism.*

Ophthalmologists in Italy concluded: “Preclinical and clinical evidences support the potential use of Astaxanthin in the prevention and treatment” of age-related vision concerns.*

Immunologists found that Astaxanthin dramatically enhanced immune response while reducing inflammation and protecting immune cells against oxidative stress.*

Gastroenterologists in 2020 noted how “Astaxanthin has important preventive and therapeutic effects” for liver health in a 2020 study, thanks to its antioxidant and anti-inflammatory abilities.*

Dermatologists in Europe confirmed its ability to protect skin from dangerous UV radiation and how it “inhibits collagenases, MMP activity, inflammatory mediators, and ROS induction."*

As a forward-thinking physician, it’s great to see mainstream medical experts and natural health advocates agree on this safe, effective phytonutrient.

The Astaxanthin Buyer’s Guide
I Give to My Patients

Unfortunately, it's hard to get the concentrated levels of Astaxanthin you need from food alone, so an Astaxanthin supplement is going to be your best move. 

However, don't just go out and buy the first Astaxanthin you see online or on the store shelf. I advise my patients to follow these simple guidelines.

1) The Right Dose Matters: The vast majority of Astaxanthin on the market provides only 4 mg. This isn’t enough. The clinical research shows you should take a triple-strength 12 mg daily dose.

2) Only Take a Softgel: The fat-soluble properties of Astaxanthin make it best absorbed when taken in an oil base, which is only possible with a softgel delivery system. 

3) Natural Astaxanthin or Nothing: Up to 95% of the Astaxanthin on the market is synthetic and has significantly weaker antioxidant properties. 

Durable SHIELD

My Patients Had a Hard Time Finding a Reliable Astaxanthin Supplement,
So I Decided to Formulate My Own

Too many of my patients were having a hard time finding naturally-sourced Astaxanthin in a 12 mg softgel.

And when they could, they found it absurdly expensive.

That’s when I decided it was time to formulate my own Astaxanthin supplement that would be of the highest quality, yet affordable. Fortunately, I also serve as Chief Science Officer for Durable™, a cutting-edge dietary supplement company that I co-founded with my good friend Josh Corn, who has been a leading natural health advocate for over 20 years. 

Together we created Durable SHIELD™ and every softgel provides a full 12 mg dose of Zanthin®, the finest, highest quality, naturally-sourced Astaxanthin.

The patented form of Astaxanthin that I hand-selected is grown in a pristine environment in Chile and extracted in the U.S. naturally without harsh solvents or harmful chemicals.

And what makes Durable SHIELD truly superior to any other Astaxanthin supplement on the market is that it includes a second super-antioxidant I also recommend to my patients: Pomanox® Pomegranate Extract.


Made from pomegranates grown in Spain’s nutrient-rich soil, Pomanox is an extremely pure, whole-fruit extract concentrated with up to 30% punicalagins, the unique polyphenols found in pomegranates that make them a prized superfood.

Studies show that Pomanox can decrease powerful pro-inflammatory compounds in the blood and increase anti-inflammatory compounds. It can also neutralize oxidative stress in joints, cartilage and connective tissue. The result is pain-free muscle and joints as well as enhanced flexibility and mobility.**

Five Reasons Why Durable SHIELD Will Make You Feel Better Every Single Day

1) 12 mg of Astaxanthin: You get triple the dose of most supplements.

2) 100% Natural and Pure: It's formulated with 100% natural Astaxanthin.

3) Enhanced with Pomanox: It's the only Astaxanthin supplement on the market that features this patented pomegranate for unrivaled antioxidant protection.

4) Quality You Can Trust: This state-of-the-art formula is produced here in the U.S. in an FDA-regulated facility for unparalleled quality.

5) Unbeatable Value and a One-Year Guarantee: Durable SHIELD is priced as low as $24.95 per bottle. And if for some reason you aren't satisfied, you have 12 months to get a 100% refund. We even pay for the return shipping.
