Ultra-Potent Body-Wide Antioxidant Protection

Durable™ SHIELD provides unparalleled antioxidant support for every cell in your body with Zanthin® astaxanthin and Pomanox® pomegranate extract, two of nature’s most effective free radical fighters.*


What It Does

Research-based doses of two extensively-studied plant extracts fight inflammation to help keep your body youthful and resilient.*

• Neutralizes free radicals that can accelerate the aging process*
• Fights inflammation to ease joint discomfort and boost endurance*
• Promotes youthful skin while protecting against UV damage*
• Provides antioxidant support for your heart, brain, eyes and more*

Why It Works

Our bodies go through a lot on a daily basis. Stress, pollution, UV light, not-so-healthy habits (like smoking) and even normal bodily functions (like breathing) create free radicals—unstable molecules that can damage healthy cells. Antioxidants can help protect your cells by neutralizing free radicals.*

While there are many antioxidants, some have more firepower than others, so it makes sense to choose the ones that give you the most “bang for your buck” when it comes to safeguarding your cells.*

Enter Durable SHIELD. We carefully selected two antioxidants shown to be among the most effective: Zanthin® astaxanthin and Pomanox® pomegranate extract.*

Astaxanthin Boasts Up To 6,000x More Antioxidant Firepower
With up to 6,000x the free radical neutralizing power of other well-known antioxidants, astaxanthin has been shown to dramatically lower markers of inflammation, enhance joint comfort, boost endurance and exercise performance, and protect your skin, heart, brain, eyes and more.*

The secret to astaxanthin’s effectiveness lies in its unique molecular structure, which is identical to that of the human cell membrane. This allows it to go where other antioxidants can’t to mount a powerful defense against free radicals and inflammation.*

Zanthin® astaxanthin is sourced from microalgae grown in a remote, pristine environment in Chile and extracted in the USA without solvents or harmful chemicals. Durable SHIELD provides an extra-strength 12 mg dose of Zanthin®, because dozens of studies have shown that astaxanthin’s benefits are most profound at this level.*

Clinically Studied Pomegranate Fights Inflammation and UV Damage
The antioxidant power of Durable SHIELD is enhanced with Pomanox®, a clinically studied extract made from pomegranates grown in nutrient-rich soil in Spain. This extremely pure whole fruit extract is standardized to contain 30% punicalagins—a much higher level than what pomegranate juice and other extracts provide. Punicalagins are among the most powerful antioxidants in nature, and emerging research is showing that they help combat inflammation, protect skin from UV damage, and promote youthful-looking skin.*

Several clinical trials have demonstrated that the 267 mg daily dose of punicalagin-rich Pomonax® found in Durable SHIELD can significantly reduce inflammation markers in the blood while increasing antioxidant markers.*

Frequently Asked Questions

and Durable co-founder Dr. Kevin Passero answers your top questions.

What is an antioxidant?


An antioxidant is a molecule that has the ability to protect cells from the damage caused by free radicals–unstable molecules that the body produces as a reaction to environmental pressures and during normal metabolism. Antioxidants work by “donating” electrons to free radicals’ unpaired electrons. This stabilizes them and effectively renders them harmless to cells.*

Is the astaxanthin in Durable SHIELD natural or synthetic?


The Zanthin® astaxanthin in Durable SHIELD is all natural. It’s sourced from the amazing marine algae species, Haematococcus Pluvialis, which produces astaxanthin as a survival mechanism when its water supply dries up to protect itself from intense sunlight. Zanthin® is grown in a pristine, controlled environment in a remote area of Chile and extracted in the US with an advanced solvent-free technology.*

How long will it take to feel the effects?


With continuous daily use, you can expect to feel an increase in your endurance and overall wellbeing within 2-4 weeks. The 12 mg dose of astaxanthin in Durable SHIELD is well known to provide tangible benefits for energy, performance and exercise recovery.*

Are there any side effects?


There are no significant known side effects associated with taking astaxanthin or pomegranate extract. However, pregnant and nursing women should consult with their health care provider prior to any use.*
