GLTN Ingredients & Drug Interactions
What is this page for?
First and foremost: checking GLTN against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of GLTN by Loomis Enzymes
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
GLTN is a multi-enzyme supplement with 10 active ingredients designed to support digestion. The product contains Lipase (a fat-digesting enzyme), Lactase (breaks down milk sugar), and Cellulase, Invertase, Glucoamylase, Hemicellulase, and Diastase — all carbohydrate-digesting enzymes.
It also includes a Proprietary Enzyme Blend, Tolerase G, and BioCore DPP-IV. The capsule also contains inactive ingredients including cellulose, water, and phytase.
Does it work?
Strong evidence
Lactase is effective for lactose intolerance — if you have trouble digesting dairy, it can help. For the other enzymes in this product, the evidence we hold is insufficient to rate how well they work for dyspepsia (indigestion) or inflammatory bowel disease (IBD).
We don't have effectiveness data on file for Lipase, Amylase, Cellulase, Invertase, Glucoamylase, Hemicellulase, Diastase, Tolerase G, or BioCore DPP-IV.
How safe is it?
Well-documented data
Lipase is generally well tolerated in supplement form, though people with serious digestive conditions should use it only under medical guidance. Lactase is generally well tolerated when used as directed.
Both have limited pregnancy and breastfeeding safety data — there isn't enough evidence to know either way, so talk with your doctor or pharmacist if you're pregnant or nursing before taking this regularly. A rare case of allergic reaction (contact dermatitis and allergic rhinoconjunctivitis) to lactase has been reported in someone handling powdered lactase, though it's uncommon.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. Still, ask your pharmacist to run your exact medications against this product before you take it.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
This product is a broad-spectrum digestive enzyme blend — especially useful if you're lactose intolerant. Since most ingredients haven't been thoroughly tested against medications, talk with your pharmacist before starting it if you take any prescriptions.
It's generally well tolerated, but people with serious digestive conditions should check with their doctor first.
