HelloPharmacist Scorecard of Enzyme 13 by Nature's Bounty
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
Full disclosure
Enzyme 13 contains 13 active digestive enzymes. Amylase breaks down carbohydrates; papain and bromelain are protein-digesting enzymes (proteases) derived from papaya and pineapple; protease is another protein-digesting enzyme; lipase breaks down fats; and lactase breaks down milk sugar (lactose).
The blend also includes cellulase, invertase, glucoamylase, alpha-galactosidase, xylanase, beta-glucanase, and hemicellulase—all enzymes that help break down plant fibers and complex carbohydrates. The capsule itself is made from vegetable cellulose, with rice flour as an inactive ingredient.
Does it work?
Strong evidence
For most of the conditions this product is used for, the evidence isn't established in the data we hold. Lactase is the one exception: it's rated effective for lactose intolerance, helping people digest milk sugar.
For papain, bromelain, and the other enzymes—covering everything from hay fever and burns to exercise-related muscle soreness—we hold insufficient reliable evidence to rate their effectiveness. That doesn't mean they don't work; it means the studies aren't there yet to confirm or rule it out.
How safe is it?
Well-documented data
Overall, the digestive enzymes in Enzyme 13 are generally well tolerated when used as directed and short-term. Papain and bromelain may irritate the digestive tract or trigger allergic reactions in sensitive people—itching, rash, digestive upset, or in rare cases with high papain doses, severe stomach inflammation or esophageal damage.
Bromelain may also cause diarrhea, gas, or headache. Protease and lipase have similar cautions around digestive upset and allergic reactions, though serious side effects are rare.
For pregnancy, papain is rated possibly unsafe and should be avoided, especially concentrated forms and unripe papaya products. Bromelain and protease are rated not safe during pregnancy.
Lactase is rated likely safe in pregnancy. For breastfeeding, papain and bromelain are best avoided due to insufficient safety data.
Lactase has limited data but acts only in the gut; ask your doctor or pharmacist before regular use. Protease and lipase also have little safety data during breastfeeding—check with your healthcare provider first.
Meds to double-check
Moderate interaction found
Check your medications before taking this product if you take warfarin (Coumadin) or other blood thinners and antiplatelet drugs—papain and bromelain may increase bleeding risk. If you take tetracycline antibiotics, bromelain may theoretically raise their levels, though the practical effect is unclear.
If any of these apply, confirm with your own doctor or pharmacist that it's okay to combine them.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Enzyme 13 is a blend of digestive enzymes useful for people with lactose intolerance (lactase is effective for that) and those seeking general digestive support, though evidence is limited for most other uses. If you take warfarin or any blood thinner or antiplatelet drug, or tetracycline antibiotics, run your exact medications through the checker below before starting—these enzymes may affect how your drugs work.
Talk with your doctor or pharmacist about whether this product fits your situation.

Enzyme 13 by Nature's Bounty Drug Interactions
HelloPharmacist Interaction Report
Enzyme 13 by Nature's Bounty contains two ingredients with documented medication interactions: papain and bromelain.
The most serious concern is papain's moderate interaction with warfarin (Coumadin), a blood thinner. Papain may increase warfarin's effects and side effects—in one case, a patient stable on warfarin developed an abnormally high INR (a measure of blood clotting) after taking a papain-containing supplement.
Read the full breakdown — every affected drug type, severity by severity
Bromelain carries a moderate interaction with anticoagulants and antiplatelet drugs (blood thinners and drugs that prevent clotting), raising the risk of bleeding. It also has a minor interaction with tetracycline antibiotics, which bromelain may theoretically increase in the bloodstream, though one study in healthy adults found no such effect at the doses tested.
Several other ingredients in this product—amylase, cellulase, invertase, glucoamylase, alpha-galactosidase, xylanase, beta-glucanase, and hemicellulase—we could not check; no interaction data is on file for them. Protease and lipase have been checked and show no documented interactions.
Altogehter, these interactions span 141 individual medications. Use the medication checker on this page to confirm your exact drugs before starting.

For each ingredient in Enzyme 13 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.
