What Is DGL Supplement Good For — Benefits and Uses?

Licorice root gets its strength from glycyrrhizin, a compound that can raise blood pressure and deplete potassium. DGL strips that compound out and keeps the rest. For anyone searching for a gentler way to calm stomach complaints, that single change is the whole point — and it’s also why DGL has stuck around in digestive care for decades.

The question of what is DGL supplement good for comes down to size: it has a small, real, well-documented niche, and it does that niche well. It is not a cure for serious disease. Here’s what the research and regulators actually say.

What DGL Is Used For

Regulators and reviews agree DGL is aimed at the upper GI tract, and the most consistently cited uses are peptic ulcers and related irritation.

That mucous layer is the stomach’s own shield — DGL is essentially asking the body to make more of it.

• Heartburn and acid reflux — the most common everyday reason people reach for it
• Peptic ulcers — the use with the deepest clinical history
• Canker sores and oral ulcers — chewables stay in contact with the mouth
• Bloating, burping, nausea, general abdominal discomfort — frequently promoted, less rigorously studied

One review lists DGL’s key uses as peptic ulcers, canker sores, and inflammatory bowel disease. Note the gap between that list and the marketing: reflux and bloating are the popular claims, while ulcers are where the evidence is strongest.

How To Take DGL And What The Evidence Shows

Product directions almost always say to chew the tablet 20 minutes before a meal and never swallow it whole — chewing is how the active compounds mix with saliva and coat the stomach.

Typical product labels suggest 1–2 chewable tablets per day, or 1 tablet before each meal. The clinical literature runs higher. That’s a wide range, so follow the label on your bottle unless a clinician tells you otherwise.

On effectiveness, the honest version: the same review notes DGL may outperform some older ulcer drugs in head-to-head studies — but those are older trials, and that does not make DGL a replacement for medical care. The National Center for Complementary and Integrative Health (NCCIH) frames licorice as a supplement with some digestive uses, not a proven treatment for serious disease.

Safety, Dose Limits, And Who Should Skip It

DGL is generally better tolerated than whole licorice, but the caveats are real and they are specific to who you are.

If you’re planning to take it indefinitely, that’s a conversation to have, not a decision to make off a label.

The bigger warning sits with the original compound. Licorice and glycyrrhizin can be risky for people with hypertension, kidney failure, diabetes, or cardiovascular disease. If any of those apply to you, check with a doctor before starting DGL — even the deglycyrrhizinated form. NCCIH’s licorice root overview lays out the full safety picture.

FAQs

Can I take DGL every day?

Many people do, and labels support daily use before meals. The catch is duration: For ongoing daily use, get a professional opinion rather than self-managing indefinitely.

Should I swallow DGL tablets or chew them?

Chew them. Instructions across DGL products consistently say to chew the tablet thoroughly and not swallow it whole — usually about 20 minutes before a meal. Chewing releases the active compounds and lets them coat the stomach lining, which is the whole mechanism behind the supplement’s digestive benefit.

Does DGL cure acid reflux or ulcers?

No. It may help soothe symptoms and support the stomach lining, and older studies suggest it can perform well against some legacy ulcer drugs. But NCCIH treats it as a supplement, not a proven treatment for serious disease. Reflux or ulcer symptoms that persist need a doctor, not a bigger dose.
