DGL Synergy Review by Designs for Health - Dr. Bell
Designs for Health DGL Synergy review by Dr. Bell. Deglycyrrhizinated licorice (DGL) with soothing botanicals to support the stomach lining, ease occasional heartburn, and comfort the gut. Dosing, who benefits, side effects, and safety.
A 49-year-old woman came to me with occasional heartburn and a touchy stomach. After certain meals, or when she was stressed, she would get that burning feeling behind the breastbone and a gnawing discomfort in her upper stomach. She did not want to be on a daily acid-blocking medication forever, and she had read that long-term use of those drugs has its own downsides. She asked if there was something gentler she could use to soothe her stomach and calm the flare-ups.
This is where DGL comes in. DGL stands for deglycyrrhizinated licorice, which is a special form of licorice root used for the gut. Licorice has been used for centuries to soothe the stomach, and the "deglycyrrhizinated" part means the one compound in licorice that can raise blood pressure has been removed, leaving the soothing part behind safely. Rather than reducing stomach acid like a drug, DGL works by supporting the protective mucus lining of the stomach and esophagus. I started her on DGL Synergy, which pairs DGL with other calming gut botanicals.
That difference in how it works, supporting the lining rather than blocking acid, is the key, and I will come back to it below. Used before her trigger meals, the burning episodes became less frequent and less intense, and her stomach felt calmer overall. DGL is not a cure for reflux and it does not replace a proper workup for ongoing symptoms, but as gentle, soothing support it is genuinely useful. DGL Synergy is the soothing gut formula I reach for.
Quick verdict: DGL Synergy is the soothing gut formula I reach for when someone has occasional heartburn or a touchy stomach and wants to calm it without suppressing their stomach acid.
Order DGL Synergy →What this product is actually doing
Your stomach and the tube leading to it (the esophagus) are protected by a layer of mucus that shields the delicate tissue underneath from stomach acid. When that protective layer is thin or irritated, acid can bother the lining, which is part of the burning and discomfort of heartburn and an irritated stomach. Standard acid-blocking drugs tackle this by reducing how much acid you make. DGL takes a different, gentler approach.
Instead of shutting down acid, DGL helps support and strengthen that protective mucus barrier. By encouraging a healthier mucus lining, it helps the tissue defend itself against the acid that is normally there, soothing irritation rather than removing the acid you need for digestion. This is an appealing approach for people who do not want to suppress their stomach acid long-term, since acid plays important roles in digestion and protection.
DGL Synergy combines DGL with other soothing, gut-friendly botanicals and nutrients (the kind traditionally used to calm and coat an irritated digestive tract). The "synergy" idea is to support the gut lining from a few complementary angles at once: strengthening the protective mucus, soothing irritated tissue, and providing a calming, coating effect. The result is gentle support for an irritated or sensitive stomach.
What is in DGL Synergy
The formula is built around soothing the gut lining:
- DGL (deglycyrrhizinated licorice) (licorice with the blood-pressure-raising compound removed, to safely support the stomach's protective mucus lining)
- Soothing botanicals (traditional gut-calming herbs that coat and comfort irritated tissue)
- Supportive nutrients for the gut lining (to round out the soothing, protective effect)
The deglycyrrhizinated part is the most important safety feature. Regular licorice contains a compound called glycyrrhizin that, taken regularly, can raise blood pressure and lower potassium. DGL has that compound removed, so you get the soothing benefit for the gut without that risk. Pairing it with other coating, calming botanicals is what makes this a "synergy" rather than a plain DGL tablet.
Who tends to do well on DGL Synergy
The pattern that responds best:
- People with occasional heartburn or acid reflux, especially after trigger meals
- Those with a touchy, easily irritated stomach or mild indigestion
- People who want to soothe the gut without suppressing stomach acid
- Those trying to reduce their reliance on daily acid-blocking medication, with provider guidance
- People whose stomach acts up more under stress
- Anyone wanting a gentle, soothing support to keep on hand for flare-ups
Who should skip it
- Anyone with frequent, severe, or worsening reflux or stomach pain, who needs a proper medical evaluation first (symptoms can overlap with conditions that need real treatment)
- People with difficulty swallowing, unexplained weight loss, vomiting, or black stools, who need prompt medical care, not a supplement
- Those who are simply self-treating long-standing symptoms that have never been worked up
- Pregnant or breastfeeding women, without provider guidance
- Anyone whose provider has told them to avoid licorice-derived products for a specific reason

Start Autoship →How to take it
Timing matters more than with most supplements.
- For DGL to coat and soothe, it usually works best taken before meals, often as a chewable, so it is present when food and acid arrive.
- Follow the label for the form you have (chewable tablets are common, since chewing helps mix the DGL with saliva and coat the tissue).
- You can use it before known trigger meals or at the first sign of a flare-up.
- It is meant for as-needed and short-to-medium-term soothing support, not necessarily forever.
- Keep up the basics that prevent reflux: smaller meals, not lying down right after eating, and limiting your personal triggers.
What to expect
- Often fairly quickly: a soothing, calming effect on an irritated stomach when used before meals
- Over days to weeks: fewer and milder flare-ups for many people who use it consistently around triggers
- It soothes and supports the lining; it does not stop acid production the way a drug does
- Best as part of an approach that also addresses meals, stress, and habits
Side effects
- Generally very well tolerated, since the blood-pressure-raising compound is removed
- Mild digestive upset in some people
- It may not be enough on its own for moderate or severe reflux
- As with anything, the risk of masking symptoms that actually need medical evaluation
What I do not love about it
My biggest caution is not about the product itself but about what heartburn can hide. Occasional, mild reflux is common and DGL is a fine soothing support for it. But frequent, severe, or worsening symptoms, trouble swallowing, unexplained weight loss, or black stools can signal something that needs real medical attention, and a soothing supplement could mask it. I never want someone using DGL for months to quiet symptoms that should have been evaluated. If reflux is a regular feature of your life, it deserves a proper workup.
It is also genuinely a soother, not a strong acid suppressor, and for people with more than occasional reflux that may not be enough. I am honest that someone with significant, frequent reflux may still need their prescribed medication, and that DGL is better suited to the milder, occasional end of the spectrum or as supportive care alongside a doctor's plan. Setting that expectation prevents disappointment.
And like most gut supplements, it works best when the habits around it change too. Large late meals, lying down after eating, and individual food and drink triggers drive a lot of reflux, and no soothing tablet fully overcomes those. I use DGL Synergy as comfortable, gentle support while also helping people adjust meal size, timing, and triggers. On its own, without those changes, it is only part of the answer.
For background, see the PMC review on licorice and gastrointestinal health, the NIH NIDDK overview of acid reflux and GERD, and the NIH NCCIH overview of licorice root.
Bottom line
DGL Synergy is the soothing gut formula I reach for when someone has occasional heartburn or a touchy stomach and wants to calm it without suppressing their stomach acid. It uses deglycyrrhizinated licorice, which supports the stomach's protective mucus lining safely, paired with other calming botanicals. Take it before meals or at the first sign of a flare, and build it on smaller meals, better timing, and avoiding your triggers.
Always check with a healthcare provider before starting any new supplement, and get frequent, severe, or worsening reflux, trouble swallowing, weight loss, or black stools properly evaluated rather than self-treated.
