HelloPharmacist Scorecard of Probiotic Quattro by Woodstock Vitamins
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
Probiotic Quattro contains 4 active ingredients, all of them live-organism probiotics. You've got Lactobacillus acidophilus, Streptococcus thermophilus, Bifidobacterium infantis, and Lactobacillus delbrueckii bulgaricus—strains chosen to support digestive health.
These come in a capsule along with inactive ingredients like cellulose, maltodextrin, and silica that help hold the formula together.
Does it work?
Moderate evidence
The evidence for these ingredients is mixed and limited. Lactobacillus acidophilus shows possibly effective ratings for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis, though the data aren't conclusive.
For the other three ingredients—Streptococcus thermophilus, Bifidobacterium infantis, and Lactobacillus delbrueckii bulgaricus—we hold insufficient evidence to rate their effectiveness for the conditions they're commonly used for, including antibiotic-associated diarrhea, constipation, and others. That doesn't mean they don't work; it means the research isn't yet solid enough to make a confident claim.
How safe is it?
Well-documented data
These probiotics are generally well tolerated in healthy adults and children. That said, they contain live organisms, so there's a theoretical risk of infection in people with weakened immune systems, severe illness, or central lines; most documented cases have occurred in those populations.
For pregnancy and lactation, the limited data suggest they're possibly safe, but ask your doctor or pharmacist before taking a probiotic supplement during pregnancy—food sources of these organisms are considered more established. Uncommon side effects from the probiotic combination itself include bloating, gas, abdominal discomfort, or diarrhea when you first start; rash and itching have been reported rarely in trials, though it's unclear which ingredient was responsible.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use antibiotic drugs (Moderate severity). Taking them at the same time may reduce the probiotic's effectiveness, so you'll likely need to space them out.
We could not check Bifidobacterium infantis for drug interactions, so search your full medication list on this page to be sure.
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.
Probiotic Quattro may help with certain digestive issues like irritable bowel syndrome or antibiotic-associated diarrhea, though the evidence isn't definitive for all uses. The big thing to watch is antibiotic timing—don't take them together.
If you're pregnant, have a weakened immune system, or are severely ill, talk with your doctor or pharmacist before starting this supplement.

Probiotic Quattro by Woodstock Vitamins Drug Interactions
HelloPharmacist Interaction Report
Probiotic Quattro by Woodstock Vitamins interacts with antibiotics through its Lactobacillus acidophilus and Lactobacillus delbrueckii bulgaricus content.
Both of these live-organism probiotics may become less effective when taken at the same time as antibiotics, since the antibiotic can kill a significant number of the probiotic organisms. The two other ingredients—Streptococcus thermophilus and Bifidobacterium infantis—were either checked with no interactions documented or we could not check for interactions.
Altogether, these interactions span 182 individual medications.
Read the full breakdown — every affected drug type, severity by severity
The main caution is with antibiotic drugs (Moderate severity). If you take antibiotics, separate them from this probiotic by a few hours or more—your doctor or pharmacist can tell you the best timing for your specific antibiotic.
We could not check Bifidobacterium infantis for interactions, so we don't have data on whether it interacts with medications. Use the search tool on this page to look up your exact medications against all the ingredients we do have information on.
