Digestive Enzyme Formula Ingredients & Drug Interactions
What is this page for?

HelloPharmacist Scorecard of Digestive Enzyme Formula by GNC Ultra Mega Green
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Most active ingredients list an amount, but at least one is hidden in a blend or missing.
Why this rating?
- The label discloses an exact amount for 10 of its 13 active ingredients.
- “CereCalase Proprietary Blend” is a proprietary blend — the label gives one combined amount (5 mg) without saying how much of each component you get.
- “n-zimes(R) Proprietary Blend” is a proprietary blend — the label gives one combined amount (145 mg) without saying how much of each component you get.
The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.
Why this rating?
- 2 of the 5 matched ingredients can interact with medications — Papain, Bromelain.
- The most serious interaction on file is rated Moderate.
- Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
- For scale: 141 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.
Why this rating?
- We hold adverse-effect (side-effect) data for 5 of the 5 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 5 of 5.
- General safety write-ups exist for 5 of 5.
- Remember: this measures how much safety information exists. Thin data is not the same as being safe.

For each ingredient in Digestive Enzyme Formula with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Bromelain
Anticoagulant/Antiplatelet Drugs
Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.
Tetracycline Antibiotics
Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.
Papain
Warfarin (Coumadin)
Theoretically, papain might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.
