HelloPharmacist Scorecard of Lact-Enz by SP Standard Process
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
Lact-Enz is a 7-ingredient digestive enzyme and probiotic blend. The active ingredients are three digestive enzymes—Amylase (breaks down starches), Protease (breaks down proteins), and Lipase (breaks down fats)—plus Cellulase (breaks down fiber), and two live beneficial bacteria: Lactobacillus acidophilus and Bifidobacterium longum.
The remaining ingredients are inactive fillers and capsule material.
Does it work?
Moderate evidence
The digestive enzymes in this product—Amylase, Protease, Lipase, and Cellulase—have no established effectiveness ratings in our data. For the probiotics: Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis, but possibly ineffective for atopic disease.
Bifidobacterium longum has insufficient evidence to rate for the conditions studied, including allergic rhinitis, antibiotic-associated diarrhea, anxiety, and asthma. The evidence for what this product can do overall is limited.
How safe is it?
Well-documented data
The digestive enzymes and probiotics in Lact-Enz are generally well tolerated by most healthy adults. Protease may rarely cause digestive upset or allergic reactions; protease is used in laundry detergents, and in rare cases occupational airborne exposure has caused allergic rhinitis or asthma, though that's not a typical risk from a supplement.
Lipase should be used only with medical guidance if you have serious digestive conditions. The probiotics may rarely cause abdominal discomfort, bloating, flatulence, or other mild digestive symptoms.
For pregnancy: Lactobacillus acidophilus is rated possibly safe. Safety data on Protease and Lipase in pregnancy are limited—the facts advise against Protease unless prescribed, and caution with Lipase only if your doctor advises it.
We hold no pregnancy safety rating for Bifidobacterium longum in the data on file. For breastfeeding, all three have limited data; check with your healthcare provider before use.
These are individual decisions—talk it over with your doctor or pharmacist.
Meds to double-check
Moderate interaction found
If you take antibiotic drugs, tell your doctor or pharmacist before starting Lact-Enz. The Lactobacillus acidophilus and Bifidobacterium longum in this product may become less effective if antibiotics are taken at the same time.
Spacing out the doses can help, but check with your own healthcare provider on the best timing for your situation.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Lact-Enz is a digestive enzyme and probiotic supplement. If you take antibiotics, separate the timing of your doses to protect the probiotics' activity.
The digestive enzymes have no proven effectiveness in our data, and the probiotics show mixed or insufficient evidence for most conditions. Anyone with serious digestive or immune issues, or anyone pregnant or breastfeeding, should confirm use with their doctor or pharmacist first.

Lact-Enz by SP Standard Process Drug Interactions
HelloPharmacist Interaction Report
Lact-Enz by SP Standard Process contains two probiotic ingredients—Lactobacillus acidophilus and Bifidobacterium longum—that interact with antibiotic drugs.
Both can theoretically become less effective if you take antibiotics at the same time, because antibiotics may kill the live organisms in the probiotics. The interaction is Moderate in severity.
Altogether, these interactions span 182 individual medications.
Read the full breakdown — every affected drug type, severity by severity
To protect the probiotics' effectiveness, space out your doses: take your antibiotic at one time of day and this supplement several hours apart, or ask your doctor or pharmacist for the best timing for your specific situation.
We could not check three other active ingredients—Amylase, Maltodextrin, and Cellulase—because we hold no data for them. Protease and Lipase have been checked and no interactions are documented in our data, though this is not a guarantee that none exist.

For each ingredient in Lact-Enz 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.
Lactobacillus acidophilus
Antibiotic Drugs
Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.
Bifidobacterium longum
Antibiotic Drugs
Theoretically, taking Bifidobacterium longum with antibiotic drugs might decrease the effectiveness of B. longum.
Since B. longum preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. longum preparations by at least 2 hours.
