HelloPharmacist Scorecard of Multi-Probiotic 4000 by Douglas Laboratories
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
Multi-Probiotic 4000 contains nine active ingredients: four live probiotic bacterial strains (Bifidobacterium longum, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium bifidum), three additional Lactobacillus and Lactococcus strains, slippery elm (Ulmus fulva), and FOS (a prebiotic fiber that feeds beneficial bacteria). The inactive ingredients are gelatin, cellulose, silica, and vegetable stearate — these are fillers and capsule materials with no active role.
Does it work?
Moderate evidence
The evidence for what this product does is mixed. Lactobacillus acidophilus is rated possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.
Bifidobacterium bifidum is rated possibly effective for irritable bowel syndrome and respiratory tract infections. For the other strains and slippery elm, the evidence we hold is insufficient to say whether they work — their effectiveness hasn't been established by reliable data.
FOS and the other ingredients we could not check have no effectiveness ratings on file.
How safe is it?
Well-documented data
The probiotic strains are generally well tolerated in healthy people, though caution is advised for anyone with a weakened immune system — there have been rare cases of serious infection (bacteremia and sepsis) in critically ill or immunocompromised patients, including preterm infants. Slippery elm is generally well tolerated for short-term use, but high-quality safety data are limited.
Both contact dermatitis and urticaria (hives) have been reported after exposure to slippery elm or its components. With the probiotic strains, uncommon gastrointestinal side effects include bloating, flatulence, abdominal pain, and diarrhea.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist about your antibiotic medications — all three of the checked live bacterial strains (Bifidobacterium longum, Lactobacillus acidophilus, and Bifidobacterium bifidum) can be killed by antibiotics if taken at the same time. Also confirm with your pharmacist whether you take any oral medications that slippery elm might interfere with — it may slow their absorption and reduce how well they work.
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.
This multi-strain probiotic may help with irritable bowel syndrome, certain infections, or antibiotic-associated diarrhea — though evidence is strongest for Lactobacillus acidophilus. The main medication concern is separating it from antibiotics so the bacteria aren't killed off.
Slippery elm may slow oral drug absorption, so check your exact medications before starting. Talk with your doctor or pharmacist first if you're immunocompromised, pregnant, breastfeeding, or taking any regular prescriptions.

Multi-Probiotic 4000 by Douglas Laboratories Drug Interactions
HelloPharmacist Interaction Report
Multi-Probiotic 4000 by Douglas Laboratories contains several probiotic strains, and through its slippery elm and three live bacterial strains (Bifidobacterium longum, Lactobacillus acidophilus, and Bifidobacterium bifidum) it has documented interactions with medications.
The most serious concern is a Moderate interaction: slippery elm may slow how your body absorbs oral drugs and reduce their levels in your bloodstream. This happens because slippery elm contains a thick, gummy substance that can interfere with medication absorption.
Read the full breakdown — every affected drug type, severity by severity
All three live bacterial strains share a Moderate interaction with antibiotics. Since these probiotics contain living organisms, taking them at the same time as antibiotics may kill off a large number of the bacteria, making the probiotic less effective.
The solution is simple: separate when you take them — ask your doctor or pharmacist how far apart to space them.
We could not check four other ingredients in this product: FOS, Lactobacillus rhamnosus (both strains), and Lactococcus lactis. Altogether, these interactions span 2,081 individual medications.

For each ingredient in Multi-Probiotic 4000 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.
Ulmus fulva
Oral Drugs
Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.
Bifidobacterium longum (Bl-05)
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.
Lactobacillus acidophilus (La-14)
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 bifidum/lactis (Bb-02)
Antibiotic Drugs
Theoretically, taking Bifidobacterium. bifidum with antibiotic drugs might decrease the effectiveness of B. bifidum.
Since B. bifidum 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. bifidum preparations by at least 2 hours.
