Dr. Passero created the Durable ACID RELIEF PLUS bundle to give his patients an advanced, multi-action strategy that addresses the underlying causes of reflux, gas, bloating and other digestive challenges for fast, long-lasting relief. While Durable ACID RELIEF rapidly soothes and heals irritated tissue in the esophagus and gut, Durable PROBIOTIC works to rebalance your microbiome to support full-spectrum digestive and immune health.*

Durable ACID RELIEF delivers immediate symptom relief in an easy-to-mix, pleasant-tasting powder containing clinically backed doses of DGL (deglycyrrhizinated licorice), aloe vera, glutamine and zinc carnosine. This unique combination of ingredients also promotes healing and optimal functioning of all parts of the digestive system by helping to improve the integrity of the gut lining and reduce gastrointestinal permeability (leaky gut).*

Meanwhile, Durable PROBIOTIC provides comprehensive microbiome and upper GI support with a blend of seven genetically verified, clinically validated strains—plus standardized artichoke extract, a natural prebiotic—in just one capsule per day. This advanced formula helps restore digestive balance, reduce reflux symptoms by up to 40%, improve regularity and comfort, and bolster immune health.*

Together, these two powerhouse formulas provide the most complete, fast-acting and lasting natural relief for both upper and lower digestive issues—while also improving gut lining integrity, microbiome balance, nutrient absorption and immune function.*

You can also save up to $31 per 1-month supply vs. buying 1 bottle of each product separately.*

This synergistic combination of powerful, clinically validated ingredients:*

• Quickly relieves heartburn and acid indigestion
• Reduces bloating and gas while improving regularity
• Improves overall digestive health in up to 85% of people
• Rapidly soothes irritation in the esophagus, stomach and small intestine
• Strengthens the intestinal lining, reducing leaky gut and related inflammation
• Relieves abdominal discomfort and nausea while enhancing bile flow and fat digestion
• Quickly balances your gut microbiome for optimal immune and overall health
• Works via the gut-heart axis to help balance cholesterol levels

Drawing on over 20 years of clinical experience, Dr. Passero created the Durable ACID RELIEF PLUS bundle to deliver the most comprehensive natural solution for people struggling with heartburn, acid indigestion, bloating, gas and other digestive challenges. By combining Durable ACID RELIEF and Durable PROBIOTIC, this bundle provides fast-acting symptom relief along with long-term digestive system healing—without the risks and side effects of conventional solutions.*

Instead of suppressing symptoms through acid-blocking drugs or generic probiotics, Durable ACID RELIEF PLUS addresses root causes through two highly targeted formulas. One supports and repairs the gut lining while calming inflammation, and the other restores microbial balance and digestive efficiency—especially in the upper GI tract, which most probiotics neglect.*

Durable ACID RELIEF
Durable ACID RELIEF delivers clinically validated relief through four powerful ingredients: DGL, aloe vera, glutamine and zinc carnosine. Each serving is designed to quickly calm irritated tissues and promote healing from the esophagus to the intestines.*

This formula begins working immediately thanks to its pleasant-tasting powder delivery system that dissolves in water. This format allows the active ingredients to come into direct contact with irritated tissues in the esophagus and stomach—making it far more effective than capsules or tablets, which don’t begin breaking down until they’ve passed through the stomach.*

Unlike conventional acid suppressants that block stomach acid (an essential component of healthy digestion), Durable ACID RELIEF supports your body's own defenses by enhancing protective mucus, repairing damaged tissues and reinforcing the intestinal barrier.*

• DGL (Deglycyrrhizinated Licorice) promotes protective mucus production throughout the GI tract while reducing inflammation and encouraging tissue repair. It has been shown in studies to relieve symptoms of reflux and acid indigestion without the blood pressure risks associated with standard licorice root. Most DGL supplements contain only 400–600 mg per dose and are delivered in tablet form. Durable ACID RELIEF provides a superior 750 mg dose in powder form for rapid and direct relief.*


• Aloe Vera (200:1 extract) has long been used to soothe inflamed tissues. Research has shown aloe to be especially effective in reducing inflammation in the esophagus and stomach, easing discomfort while supporting microbiome balance. Our patented extract is sourced from the inner leaf only—free of the laxative compounds found in the outer leaf—and has 300% more bioactive polysaccharides than conventional extracts, enhancing its healing properties.*


• Glutamine, an essential amino acid, provides the primary fuel for intestinal cells and is vital for maintaining and restoring the integrity of the gut lining. Durable ACID RELIEF includes 3,000 mg per serving—clinically validated to reduce gut permeability (leaky gut), inflammation and digestive discomfort. Glutamine also supports tight junction integrity, which helps prevent immune-disrupting substances from passing into the bloodstream.*


• Zinc Carnosine, a unique compound approved in Japan for gastric health, has been clinically proven to bind to inflamed tissue in the stomach lining and accelerate the repair process. Studies show that it supports healthy acid balance, improves gut barrier function, and enhances mucosal healing. Unlike ordinary zinc supplements, zinc carnosine remains in the stomach longer and delivers more targeted healing benefits.*

Together, these four ingredients address the root causes of acid discomfort—from irritation and inflammation to gut barrier dysfunction—helping to restore lasting balance to your digestive system. And unlike acid blockers, which may provide short-term relief at the expense of long-term digestive health, Durable ACID RELIEF promotes real healing while supporting optimal nutrient absorption and microbiome function.*

Durable PROBIOTIC
Durable PROBIOTIC delivers full-spectrum digestive support with a potent 22 billion CFU dose from seven diverse, genetically verified probiotic strains. Each strain is backed by human clinical research and cultivated in FDA-inspected U.S. labs to ensure maximum quality, consistency and efficacy.*

These strains have been shown in 427 human clinical trials to relieve bloating, reduce gas, improve regularity and support immune function. Impressively, the strains in Durable PROBIOTIC were shown to improve overall digestive health in 85% of people within 30 days, while significantly reducing bloating in 78% of people, easing constipation in 74% of people and relieving abdominal discomfort in 80% of people.*

Unlike most probiotics, which only focus on colon health, Durable PROBIOTIC works across the entire digestive system—including the stomach and small intestine. This is especially important for people experiencing upper GI issues like reflux, nausea or indigestion, which are often overlooked by typical probiotic formulas.*

A key differentiator is Durable PROBIOTIC’s inclusion of 320 mg of standardized artichoke extract—a clinically studied digestive aid that has been shown to:

• Promote healthy bile flow and improve fat digestion
• Relieve upper GI symptoms, including reflux, by 40%
• Reduce nausea by 53%
• Ease bloating and abdominal discomfort

Artichoke extract also serves as a gentle, non-bloating prebiotic, supporting the probiotic strains and encouraging a more balanced microbiome. Unlike common prebiotics such as inulin or FOS, which can worsen bloating in sensitive individuals, artichoke is well-tolerated and actively contributes to enhanced digestive comfort.*

Each strain in Durable PROBIOTIC offers its own unique benefits:

• L. rhamnosus HN001™ and L. acidophilus NCFM® reduce gas and bloating while supporting immune function and gut barrier integrity*
• B. lactis Bi-07™, Bl-04®, and HN019™ improve regularity and enhance upper respiratory immune defenses*
• B. lactis DSM 15954™ supports microbial diversity and reduces gut inflammation*
• L. paracasei LPC-37® promotes microbial balance and helps relieve upper digestive discomfort*

Together, these strains and the artichoke extract work synergistically to rapidly reduce digestive discomfort, enhance gut resilience, and improve overall health via the gut-immune and gut-brain axes.*

In short, Durable PROBIOTIC offers unmatched breadth and depth of support—relieving bloating, reflux and constipation while also supporting immune strength, cholesterol balance and long-term microbiome health.*
