HelloPharmacist Scorecard of Sml Classic by Loomis Enzymes
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
Sml Classic is an enzyme and probiotic powder with 12 active ingredients. It contains digestive enzymes — Amylase, Cellulase, Glucoamylase, Alpha-Galactosidase, and Hemicellulase — designed to break down carbohydrates and fiber.
It also includes a Probiotic Blend and a Proprietary Plant Enzyme Blend, along with several individual probiotic strains: Lactobacillus rhamnosus, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus plantarum, and Bifidobacterium longum. There's also Fiber to support digestion.
The product contains one inactive ingredient, Inulin, which serves as a filler.
Does it work?
Moderate evidence
The probiotics in this product have varying levels of evidence. Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.
Bifidobacterium longum, however, has insufficient evidence to rate for the conditions studied — including antibiotic-associated diarrhea, allergic rhinitis, anxiety, and asthma. The digestive enzymes and other probiotic strains don't have effectiveness ratings in our data, so we can't speak to how well they work.
How safe is it?
Well-documented data
Lactobacillus acidophilus is generally well tolerated in healthy adults and children, though you should check with your doctor before using it. Bifidobacterium longum is also generally well tolerated in healthy people, but caution is advised if you're seriously ill or have a weakened immune system.
Both ingredients contain live organisms, so there's a theoretical risk of infection in vulnerable patients — cases of bacteremia and sepsis have been reported in critically ill infants, though this is rare. Gastrointestinal side effects like bloating, gas, abdominal discomfort, and diarrhea are uncommon but possible with probiotic combinations.
No pregnancy or lactation data are on file for Lactobacillus acidophilus, and Bifidobacterium longum is rated possibly safe — talk with your doctor or pharmacist about using this product while pregnant or breastfeeding.
Meds to double-check
Moderate interaction found
If you take antibiotic drugs, separate them from this product — antibiotics can kill the live probiotics and make them less effective. Ask your pharmacist how to time the doses.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product is a blend of digestive enzymes and probiotics meant to support digestive health. If you take antibiotics, you'll need to space them apart from this supplement.
Anyone who's seriously ill or immune-compromised should check with their doctor first. Run your medications through the checker below to make sure nothing else interacts.

Sml Classic by Loomis Enzymes Drug Interactions
HelloPharmacist Interaction Report
Sml Classic by Loomis Enzymes contains probiotics that may interact with antibiotic drugs.
Lactobacillus acidophilus and Bifidobacterium longum can both be affected by antibiotics taken at the same time — the antibiotics may kill off the live organisms in the probiotic, reducing its effectiveness. This is a Moderate-severity concern with both ingredients.
Read the full breakdown — every affected drug type, severity by severity
The interaction is straightforward to manage: separate when you take them. Ask your pharmacist how long to wait between your antibiotic dose and this supplement — usually a few hours is enough, but timing depends on the specific antibiotic.
We were not able to check several other ingredients in this product — Amylase, Cellulase, Glucoamylase, Alpha-Galactosidase, Hemicellulase, Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus plantarum, and Fiber — because we don't hold interaction data for them.

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.
