HelloPharmacist Scorecard of LactoseStop by Renew Life
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
LactoseStop contains six active ingredients designed to help break down lactose. Lactase is the primary enzyme that splits lactose (milk sugar) into simpler sugars your body can absorb—it's rated effective for lactose intolerance.
Papain and lipase are additional digestive enzymes that help break down proteins and fats, though the evidence for their standalone benefits is limited. L. sporogenes is a probiotic (Bacillus coagulans) meant to support gut health.
Fenugreek is an herb traditionally used for various purposes, and galactomannan is a fiber. The capsule itself is vegetable-based.
Does it work?
Strong evidence
Lactase is effective for lactose intolerance and is the ingredient doing the main work here. Fenugreek is rated possibly effective for sexual function and diabetes management, and L. sporogenes is possibly effective for constipation and irritable bowel syndrome.
Papain, lipase, and galactomannan have insufficient reliable evidence in our data to say whether they work for their proposed uses—the evidence just isn't established well enough to rate them.
How safe is it?
Well-documented data
Lactase is generally well tolerated and likely safe in pregnancy and while breastfeeding when used as directed. Papain is generally tolerated as a food but supplements may irritate the digestive tract and cause allergic reactions in sensitive people; it's possibly unsafe in pregnancy (concentrated forms and unripe papaya should be avoided), and there's not enough data to safely recommend it while breastfeeding.
L. sporogenes is generally well tolerated in healthy adults but evidence and product quality vary; it carries a small risk of serious infection (bacteremia and sepsis) in people with central lines, severe illness, or weakened immune systems, though this is rare in healthy people with intact defenses. Fenugreek is generally well tolerated at food amounts but supplement doses may cause abdominal pain, bloating, diarrhea, or nausea; it's likely unsafe in pregnancy (medicinal doses may affect the uterus), though it's possibly safe while breastfeeding and is often used to support milk supply.
Lipase is generally well tolerated but limited pregnancy and breastfeeding data exists. Allergic reactions to papain and fenugreek (including severe ones with swelling, wheezing, or shock) are rare but possible.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you take warfarin or other blood thinners (including clopidogrel)—papain and fenugreek may increase bleeding risk. Also double-check if you take diabetes medications (fenugreek may lower blood sugar further), heart drugs like metoprolol, seizure medications like phenytoin, theophylline for asthma, sildenafil (Viagra), or any antibiotics.
Antibiotics and the probiotic L. sporogenes should be separated by a few hours so the antibiotic doesn't kill off the live organisms.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you have lactose intolerance and take no medications that interact with these ingredients, LactoseStop may help you digest dairy. If you take blood thinners, diabetes drugs, heart medications, seizure drugs, antibiotics, or any other prescription, check with your doctor or pharmacist first—this product has significant interactions.
Pregnant or breastfeeding women should also discuss it with their healthcare provider before starting, especially due to papain and fenugreek.

LactoseStop by Renew Life Drug Interactions
HelloPharmacist Interaction Report
LactoseStop by Renew Life contains several ingredients with documented interactions with medications.
The most serious concern involves papain and warfarin (a blood thinner)—papain may increase warfarin's effects and bleeding risk, as shown in a case where a patient's blood-thinning level became dangerously high after taking a papain-containing supplement. Fenugreek, another ingredient here, interacts with multiple drug types and carries Moderate severity across the board.
Read the full breakdown — every affected drug type, severity by severity
Fenugreek can affect blood thinners (anticoagulants and antiplatelet drugs like warfarin and clopidogrel), diabetes medications, and several others including theophylline (an asthma drug), metoprolol (a heart medication), phenytoin (a seizure drug), and sildenafil (Viagra). It may reduce blood sugar or blood pressure, or alter how your body processes these drugs.
L. sporogenes (Bacillus coagulans), a probiotic in this blend, interacts with antibiotics—taking them at the same time may kill off the live organisms and reduce the probiotic's benefit, so they should be separated by a few hours.
Lactase and lipase have no interactions documented in our data. Galactomannan could not be checked—we hold no data for it.
Altogether, these interactions span 570 individual medications. Please use the medication checker on this page to see if any of your prescriptions are affected, and talk with your doctor or pharmacist before starting this product if you take blood thinners, diabetes drugs, heart or seizure medications, or antibiotics.

For each ingredient in LactoseStop 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.
Fenugreek
Anticoagulant/Antiplatelet Drugs
Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .
Antidiabetes Drugs
Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.
Clopidogrel (Plavix)
Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.
Metoprolol (Toprol)
Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.
Phenytoin (Dilantin)
Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.
Sildenafil (Viagra)
Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.
Theophylline
Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.
Warfarin (Coumadin)
Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.
Antihypertensive Drugs
Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.
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.
