DGST Ingredients & Drug Interactions
by Thera-Zyme
What is this page for?
First and foremost: checking DGST 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
DGST is a dietary supplement by Thera-Zyme with 9 active ingredients. Its ingredients are commonly taken for digestion and bloating, muscle soreness and exercise recovery, inflammation and swelling.We don’t currently list a known drug interaction for its mapped ingredients — but that doesn’t guarantee none exist, so always confirm with your pharmacist.
HelloPharmacist Scorecard of DGST by Thera-Zyme
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
Thera-Zyme DGST is a digestive enzyme blend with nine active ingredients designed to support the breakdown of food. It contains three major enzyme types: Protease (which breaks down proteins), Lipase (which breaks down fats), and Lactase (which breaks down lactose in dairy).
The product also includes Amylase, Cellulase, Invertase, Glucoamylase, Hemicellulase, and Diastase — additional carbohydrate-digesting enzymes — plus a Proprietary Plant Enzyme Blend. The capsule itself is made from vegetable material, with Phytase listed as an inactive ingredient.
Does it work?
Couldn't assess
The evidence for these enzymes is limited. Lactase is effective for lactose intolerance — that one's well established.
For Lipase and Protease, the research we have rates the evidence as insufficient to say whether they work for digestive upset (dyspepsia) or inflammatory bowel disease (IBD). The evidence for the other active ingredients in this product isn't established in our data.
How safe is it?
Well-documented data
Protease, Lipase, and Lactase are generally well tolerated in adults, though digestive upset is possible with any of them. Rare allergic reactions to proteolytic enzymes have been reported, especially with airborne exposure in occupational settings.
During pregnancy, safety data is limited for all three — the facts advise checking with your doctor before use. Breastfeeding also has little data; talk to your healthcare provider first.
Lactase alone is rated likely safe in pregnancy. For the other active ingredients, safety information isn't on file here.
Meds to double-check
No known interactions
No interactions are documented in our data for the digestive enzymes we could check in this product.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you have lactose intolerance, Lactase in this product is an effective choice. For general digestive support with the other enzymes, the evidence is thin.
If you're pregnant or breastfeeding, check with your doctor or pharmacist before starting — safety data is sparse. No documented interactions with medications, but run your prescriptions through the checker if you want to be thorough.
