Drawing on over two decades of clinical experience, Dr. Kevin Passero designed this formula to help his patients get comprehensive and effective natural relief from acid-related digestive issues. By targeting multiple underlying factors, it offers unparalleled immediate and long-term benefits, improving overall gut health and quality of life.*

Durable ACID RELIEF provides fast-acting natural relief from heartburn, acid indigestion and digestive discomfort with a powerful blend of clinically backed ingredients that address multiple causes of acid issues while strengthening the lining of your gut.*

Unlike traditional pills, this pleasant-tasting, naturally sweetened powder dissolves easily in water, delivering immediate relief by directly coating and soothing irritated tissues. Each serving includes 750 mg of DGL (deglycyrrhizinated licorice) extract, 100 mg of aloe vera (in a potent 200:1 concentration), 3,000 mg of glutamine and 75 mg of zinc carnosine.*

This unique combination of ingredients is also designed to promote healing and optimal functioning of all parts of the gastrointestinal system by helping to improve the integrity of the gut lining, support a healthy microbiome and reduce gastrointestinal permeability (leaky gut), which is associated with disordered immune activity and subsequent gut and body-wide inflammation.*

While conventional solutions may offer temporary symptom relief by blocking stomach acid, this approach fails to address the root causes of the acid issues and has been linked to dangerous side effects when used long-term.*

If you're struggling with heartburn, acid indigestion or other digestive issues, you're not alone. These are among the most common concerns that bring patients to Dr. Passero’s clinics in search of a natural solution.*

While conventional solutions may offer temporary relief by blocking stomach acid, they often fail to address the root cause. And they aren’t deemed safe for continuous long-term use and have been linked to serious long-term health issues.*

Durable ACID RELIEF takes a different approach, offering natural, research-backed ingredients that work in harmony with your body to soothe and heal irritated tissue in the digestive tract.*

In Dr. Passero’s over 20 years of clinical experience, acid indigestion is often a symptom of a deeper imbalance in the digestive system. By assisting and supporting the body’s natural healing response (rather than simply masking the symptoms), patients experience comprehensive symptom relief through the restoration of optimal digestive tract function. In the process, many also experience improvements in their sleep, energy and immune function. This is in sharp contrast to the relief obtained by conventional solutions that often come with major side effects and do little to restore balance back to the gut.*

Dr. Passero designed Durable ACID RELIEF to be the most comprehensive and effective supplement of its kind. By targeting multiple causes of acid indigestion, it offers unparalleled immediate and long-term relief, improving gut health and overall quality of life.*

Durable ACID RELIEF contains clinically effective doses of four powerful, scientifically proven ingredients: DGL, aloe vera, glutamine and zinc carnosine in a pleasant-tasting, naturally sweetened powder that dissolves easily in water.*

Through 20+ years of helping patients address acid issues naturally, Dr. Passero has found these four ingredients to provide the fastest symptom relief while also healing and strengthening the digestive system at its core.*

Unlike conventional solutions, which temporarily relieve symptoms by suppressing stomach acid, Durable ACID RELIEF addresses the root causes of acid issues while supporting overall digestive health.*

Stomach acid is essential to health, and contrary to popular belief, most acid issues are caused by too little stomach acid, not too much. Stomach acid plays a critical role in defending against harmful microorganisms, breaking down proteins, and helping your body absorb key vitamins and minerals. Suppressing stomach acid long-term with conventional solutions can lead to grave health consequences including bone fractures and hard-to-treat infections.*

These ingredients work synergistically via multiple mechanisms to restore digestive comfort and improve gut health. They enhance the integrity of the gut lining, support a healthy microbiome, and reduce gastrointestinal permeability (leaky gut)—a factor often linked to immune activation and systemic inflammation.*

DGL (Deglycyrrhizinated Licorice): A Time-Tested Herb for Fast-Acting Acid Relief (750 mg)
Licorice root has been used in traditional medicine for centuries for its soothing, anti-inflammatory properties. However, regular licorice contains glycyrrhizin, a compound that can cause side effects like increased blood pressure.*

Deglycyrrhizinated licorice (DGL) is a specially processed form of licorice with the glycyrrhizin removed, making it a safer option that retains the root’s beneficial properties without the potential health risks.*

DGL supports the health of the esophagus, stomach and intestinal lining by promoting the secretion of protective mucus throughout the gastrointestinal (GI) tract. This mucus is essential for shielding the stomach from acid’s erosive effects, strengthening the body's natural defense without suppressing acid production.*

Additionally, DGL aids in the healing of inflamed tissues in the stomach and digestive tract by regulating prostaglandins—compounds that help maintain and protect the gut lining.*

Research suggests that DGL effectively relieves acid indigestion by enhancing mucus production and protecting the gut lining. Furthermore, studies indicate that DGL helps shield the stomach lining from the harmful effects of non-steroidal anti-inflammatory drugs (NSAIDs).*

Most DGL supplements come in chewable tablets, typically providing 400–600 mg per serving. Durable ACID RELIEF delivers a clinically validated, extra-strength 750 mg dose in a superior powder form, which more effectively coats the esophagus, stomach and intestinal lining for optimal relief and protection.*

Aloe Vera: A Natural, Anti-Inflammatory Soother (100 mg in a 200:1 concentration)
Most people are familiar with the skin-healing properties of aloe vera. If you’ve ever split open a fresh aloe leaf, you’ve seen the thick, gel-like substance inside—commonly used to soothe and heal irritated skin. But aloe vera’s benefits go beyond the skin—it also supports healing in the esophagus and digestive tract.*

However, like licorice, aloe contains certain compounds that can cause unwanted side effects. The latex portion of the aloe leaf acts as a powerful laxative—an effect we want to avoid when addressing acid issues.*

Aloe vera helps reduce inflammation in the esophagus and stomach lining, promoting healing and easing discomfort. It also supports digestion and helps balance stomach acidity for overall gut health.*

Clinical studies suggest that aloe vera juice effectively reduces symptoms of acid indigestion and heartburn without side effects. Research also indicates that acid issues may be driven more by inflammation than by direct acid damage—making aloe’s natural anti-inflammatory properties especially beneficial.*

To allow you to experience the full anti-inflammatory digestive benefits of aloe vera without unwanted side effects, our aloe is carefully extracted only from the inner leaf gel, ensuring it contains none of the laxative compounds found in the latex portion of the plant.*

Glutamine: The Gut-Healing Amino Acid (3,000 mg)
Glutamine is an amino acid that supports gut health and mucosal repair by fueling the cells lining the digestive tract, promoting tissue regeneration and strengthening the intestinal barrier. It also helps reduce inflammation and gut permeability (leaky gut), both of which are linked to acid issues and digestive discomfort.*

Glutamine activates signaling pathways within gut cells that increase the expression of tight junction proteins. This helps bond the gut cells together, which reinforces the gut lining and prevents harmful substances from leaking into the bloodstream and triggering inflammation.*

By supporting a healthy inflammatory response in the intestines, glutamine can also help alleviate bloating, gas and irregularity. Additionally, glutamine promotes the growth of beneficial bacteria while inhibiting harmful bacteria.*

Through these multiple mechanisms of action, glutamine provides powerful long-term relief from acid issues and supports overall digestive health.*

Durable ACID RELIEF delivers a clinically validated 3,000 mg dose of glutamine in a superior powder form for optimal absorption and maximum effectiveness.*

Zinc Carnosine: A Unique and Proven GI-Healing Compound (75 mg)
Zinc carnosine is a specialized combination of zinc and carnosine, clinically studied for its protective and healing effects on the gastrointestinal tract. Extensively researched for acid-related discomfort, it has been used in Japan as an approved therapy for gastric issues due to its strong clinical validation.*

Unlike standard zinc supplements, zinc carnosine is insoluble in saline but dissolves in acid, allowing it to stay in the stomach longer and provide targeted healing to damaged cells.*

Possessing unique adhesive properties, zinc carnosine has been shown to bind to irritated stomach tissue, helping to stabilize membranes, reduce inflammation and accelerate healing.*

Considered essential for tissue repair, zinc plays critical roles in collagen synthesis, cell regeneration and immune support, all of which contribute to strengthening the stomach lining and enhancing mucosal defenses against acid damage.*

Durable ACID RELIEF provides a clinically proven 75 mg dose of zinc carnosine in a superior, easy-to-absorb powder form.*

A Superior, Holistic Approach to Acid Relief
Dr. Passero has found that combining DGL, aloe vera, glutamine and zinc carnosine provides a comprehensive, highly effective natural approach to managing acid issues and other digestive symptoms.*

If heartburn or acid indigestion make it hard to get the restful sleep you need at night, or bother you throughout the day, you’ll find that Durable ACID RELIEF provides the fast relief you need. Its ingredients work synergistically to quickly ease discomfort, while repairing the gut lining, reducing inflammation and balancing your microbiome over time.*

With its pleasant-tasting, lightly sweetened powder delivery system that dissolves quickly in water, Durable ACID RELIEF ensures that the active compounds it contains come into direct contact with the esophagus and stomach lining, which are the tissues most often responsible for symptoms associated with acid indigestion.*

Other supplements that come in capsule or tablet form completely bypass the esophagus and often do not fully dissolve until they leave the stomach, thus failing to provide significant relief of symptoms. In addition, the powder ensures maximum and immediate contact with irritated tissue in the stomach and small intestine, without the need to wait for the disintegration of a capsule or tablet, enhancing the healing and anti-inflammatory benefits.*
