If you are dealing with the daily sting of heartburn or the dull ache of gastritis, you already know that quick-fix antacids only mask the fire without healing the lining. A properly formulated DGL (deglycyrrhizinated licorice) works differently—it coats and soothes the stomach and esophageal tissues rather than simply neutralizing stomach acid. The problem is that 90% of the licorice supplements on the market either lack proper DGL processing (leaving blood-pressure-spiking glycyrrhizin intact) or use such cheap fillers that the active compounds never actually work.
I’m Mohammad — the founder and writer behind ProteinJug. I have spent over a decade analyzing supplement supply chains, scrutinizing third-party lab reports, and mapping which DGL brands actually invest in quality deglycyrrhinization versus which ones just slap the word licorice on a label.
This buying guide breaks down the five DGL supplements that survive real-world testing for potency, purity, and mucosal support so you can finally put out the fire without hiding the smoke. Here is my curated list of the best dgl supplement options on the market right now.
How To Choose The Best DGL Supplement
Not every bottle labeled licorice root qualifies as DGL. The deglycyrrhizination process strips away 97% or more of glycyrrhizin, the compound responsible for raising blood pressure and depleting potassium. A real DGL should have less than 1% glycyrrhizin by weight. Beyond that single safety check, three other pillars dictate whether a DGL actually delivers relief.
Delivery form matters more than you think
Chewable DGL tablets work best when you have active heartburn because the saliva mixes with the supplement and coats the esophagus on the way down. Capsules bypass the throat entirely and work primarily in the stomach. If your pain sits high—in the throat or chest—a chewable formula gives faster, more direct contact. Capsules suit deeper gut issues like gastritis or general stomach lining repair.
Supporting ingredients that amplify results
DGL works by thickening the mucus barrier, but it does not rebuild damaged tissue. Zinc carnosine, mastic gum, and slippery elm each address different layers of the problem. Zinc carnosine accelerates epithelial cell repair; mastic gum targets H. pylori and general microbial balance; slippery elm adds a second layer of physical coating. A multi-target formula often outperforms standalone DGL for chronic cases.
Third-party testing and manufacturing transparency
DGL supplements are not FDA-regulated for efficacy. The only real quality signal is how the manufacturer handles sourcing and testing. Look for GMP-certified facilities and brands that voluntarily disclose heavy metal screens and potency assays. Brands that previously sold exclusively through physician channels—integrative medicine cabinets—tend to maintain higher raw material standards.

In‑Depth Reviews
1. Integrative Therapeutics Rhizinate
Integrative Therapeutics Rhizinate is the closest thing to a clinical-grade DGL that is available without a prescription. This formula was originally sold exclusively through physician offices, which means the raw material sourcing and manufacturing controls had to pass the strictest quality thresholds. Each chewable tablet contains a sugarless, fructose-free DGL base that keeps the glycyrrhizin content below 1%—so you get the mucosal coating benefits without worrying about your blood pressure drifting upward. The chewable format is key here: it mixes with saliva to coat the throat and esophagus directly, making it ideal for people whose reflux pain sits high in the chest or feels like a lump in the throat.
Long-term users in the community, some spanning five years, consistently report that it replaces antacid tablets entirely rather than just supplementing them. The absence of artificial colors, preservatives, soy, and dairy means it fits almost any elimination diet. The texture is dry and chalky in the mouth, but the fruity taste is mild enough that even people who hate licorice flavors do not gag on it. Each bottle holds 100 tablets, which for a moderate user translates to roughly two to three months of daily use.
One caveat: the tablets are not coated, so they soften quickly if exposed to moisture. Keep the lid threaded tightly, especially if you live in a humid environment. For consistent, predictable throat-level relief that stays away from dangerous glycyrrhizin levels, this is the benchmark.
Why it’s great
- Fructose-free and sugar-free formula ideal for dietary constraints
- Less than 1% glycyrrhizin eliminates blood pressure concerns
- Chewable format coats throat and esophagus on the way down
Good to know
- Tablets are moisture-sensitive and can soften if jar is left open
- Taste is mild but distinct—not suited for those who dislike any herbal note
2. NOW Foods Gastro Comfort
NOW Foods Gastro Comfort stands out because it does not rely on DGL alone to get the job done. Each capsule packs deglycyrrhizinated licorice extract alongside mastic gum, aloe vera, and slippery elm bark—targeting the stomach lining from four different angles. Mastic gum addresses microbial factors like H. pylori, aloe soothes inflammation, and slippery elm provides an additional physical barrier over the mucus layer. This makes the formula particularly effective for people dealing with deeper gastritis, leaky gut symptoms, or stubborn ulcer flare-ups rather than episodic heartburn.
The capsules are easy to swallow and do not require chewing, which makes dosing consistent for those who take it as a daily maintenance supplement rather than an emergency chewable. NOW Foods operates under GMP-certified manufacturing, and their quality documentation is more transparent than most mid-range supplement companies. Several users report that combining this capsule with a separate aloe or zinc regimen feels redundant—something to consider if you already take multi-ingredient gut supplements.
The feedback from chronic gastritis patients is the most compelling: many report relief within the first week, especially for the gnawing upper-abdominal pain that comes with an empty stomach. The one behavioral issue to watch is daily dosing tolerance—a small number of users notice mild stomach discomfort if taken continuously for more than two weeks, which usually resolves with a two-day break. For a well-rounded, multi-target approach to gut lining repair, this delivers solid value in a single bottle.
Why it’s great
- Four supportive ingredients in one capsule reduce supplement clutter
- GMP-certified manufacturing with transparent quality testing
- Works fast on empty-stomach gastritis pain and ulcer discomfort
Good to know
- Continuous daily use may cause mild stomach upset in some users
- Not designed for on-the-spot throat-level heartburn relief
3. Nature’s Way DGL Ultra
Nature’s Way markets this as an extra-strength DGL—not because it contains more glycyrrhizin (it stays under the safe 1% threshold), but because it uses Gutgard, a specialized licorice extract standardized to a higher concentration of active mucoadhesive compounds. The result is a capsule that provides deeper, longer-lasting contact with the stomach lining compared to standard DGL powders. This matters most for people whose digestive distress feels diffuse across the entire upper GI tract rather than pinpointed in the throat.
The capsules are notably clean: no salt, yeast, wheat, corn, soy, dairy, or artificial colors. Nature’s Way also packages the bottle in 97% post-consumer recycled materials, a small but visible commitment to manufacturing ethics. The taste feedback is interesting—several people actually enjoy the subtle licorice flavor of the capsule itself, which is rare for any herbal supplement. The 90-count bottle offers good longevity for daily users who take one or two capsules per day.
Where this product falls slightly short is specificity. For acute, acute-phase throat burn, a chewable format delivers faster relief. The capsule form bypasses the esophagus and releases in the stomach, so if your primary symptom is laryngopharyngeal reflux (LPR) or throat irritation, you will get better mileage from a chewable like the Integrative Therapeutics option above. For general stomach lining upkeep and occasional lower-chest burn, the extra concentration of Gutdard makes this a reliable daily driver.
Why it’s great
- Gutgard technology delivers concentrated mucoadhesive compounds
- Free from the top 8 allergens and common fillers
- Bottle packaging uses recycled materials
Good to know
- Less effective for immediate throat-level burn relief
- Some users expected a stronger effect given the extra strength label
4. Enzymedica Acid Soothe
Enzymedica Acid Soothe takes a completely different approach from traditional DGL. Instead of deglycyrrhizinated licorice, this product pairs zinc carnosine with a proprietary blend of Thera-blend digestive enzymes. Zinc carnosine is one of the most clinically studied compounds for gastric lining repair—it accelerates the regeneration of epithelial cells in the stomach wall. This makes the formula particularly useful for people whose main problem is not excess acid but a compromised mucosal barrier that burns when exposed to normal stomach acid.
The chewable tablet uses organic tapioca dextrose as a base, so it avoids the chalky texture of classic DGL tablets. Users report that it starts providing relief within minutes rather than requiring a loading period of several days. The flavor is mild and inoffensive, which encourages consistent post-meal dosing. Many people combine this with a DGL for a two-pronged approach: enzymes handle immediate digestion and zinc handles the cellular repair side. The bottle holds 60 tablets, which at one per meal provides roughly a 20-day supply—shorter than the other options here.
One important behavioral note: the fast relief effect can mask underlying issues. Several user reports describe needing to graduate to a higher-potency regimen—like combining it with Famotidine or a longer-term DGL protocol—once the initial honeymoon phase passes. This is not a standalone fix for moderate to severe GERD, but as an acute-onset chewable that also rebuilds tissue, it fills a unique slot that no single DGL product on this list touches.
Why it’s great
- Zinc carnosine directly stimulates stomach lining repair
- Chewable format dissolves quickly with a pleasant taste
- Enzyme blend aids digestion of trigger foods in real time
Good to know
- Shorter bottle life—60 tablets may last only three weeks
- Not a true DGL; different mechanism than deglycyrrhizinated licorice
5. Himalaya Organic Licorice
Himalaya Organic Licorice is included here with a major label: this is not a DGL. The product uses full-spectrum organic licorice root powder and extract, which means it contains the natural glycyrrhizin content that DGL strips away. For people with healthy blood pressure and no history of hypertension or heart issues, that glycyrrhizin can support general digestion and occasional bloating relief through the traditional Ayurvedic mechanism of soothed bowel function. The organic certification is real, the vegan non-GMO profile is clean, and the price point is the lowest per bottle in this roundup.
The catch is severe enough that it has been documented in real customer experiences: a healthy 29-year-old user saw their blood pressure spike to 160/100 after taking these pills to treat heartburn. Glycyrrhizin inhibits the enzyme that breaks down cortisol, leading to sodium retention and potassium loss. If you have any cardiovascular condition, borderline hypertension, or take blood pressure medication, this product is not safe. Even for healthy individuals, long-term use carries the same risk, which is exactly why most licorice research has moved toward deglycyrrhizinated formulations.
For short-term, occasional use in otherwise healthy adults—say, a week of bloating relief after a bout of overeating—the Himalaya Organic Licorice works well. It is also the only entry on this list that addresses immune support through a separate herbal pathway, which some users find appealing. But for anyone who clicked this article specifically looking for a DGL supplement to manage chronic acid issues, this is the wrong bottle to grab unless you understand and accept the blood pressure trade-off.
Why it’s great
- Certified USDA Organic with clean vegan/non-GMO ingredients
- Traditional Ayurvedic formula for general digestive support
- Lowest cost per bottle if used for short-term relief
Good to know
- Not deglycyrrhizinated—contains full glycyrrhizin that can spike blood pressure
- Dangerous for anyone with hypertension or cardiovascular issues

Final Thoughts: The Verdict
For most users, the best dgl supplement winner is the Integrative Therapeutics Rhizinate because it combines a physician-grade manufacturing history with a fructose-free chewable format that hits throat-level reflux immediately while staying safe on blood pressure. If you want a multi-ingredient capsule that addresses deeper gastritis and leaky gut from several angles, grab the NOW Foods Gastro Comfort. And for cellular repair of the stomach lining through zinc carnosine rather than licorice, nothing beats the Enzymedica Acid Soothe as a targeted acute relief tool that also heals tissue over time.
