HelloPharmacist Scorecard of Synbiotic by NutriCology Restore-Biotic

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (30 mg) without saying how much of each component you get.

This product has 3 active ingredients: Lactobacillus acidophilus DDS-1 (a live probiotic bacterium), Bifidobacterium lactis UABIa-12 (another live probiotic), and Xylo-oligosaccharides (a prebiotic carbohydrate that feeds beneficial bacteria). These work together — the live organisms support your gut health, and the prebiotic helps them thrive.

The product also contains silica as an inactive ingredient.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Digestive health and probiotic balance.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Constipation, Irritable bowel syndrome (IBS), Lactose intolerance — and 4 related terms.
  • The strongest evidence on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Bacterial vaginosis, Irritable bowel syndrome (IBS).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Lactose intolerance, Rotaviral diarrhea, Travelers' diarrhea.

Lactobacillus acidophilus has possibly effective evidence for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (allergic conditions), and we don't have enough reliable evidence to rate it for acute respiratory distress syndrome (ARDS).

We don't hold effectiveness data for the other two active ingredients in this product.

The evidence, ingredient by ingredient Lactobacillus Acidophilus

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lactobacillus acidophilus is generally well tolerated in healthy adults and children. It's considered low risk overall, though data are limited — check with your doctor before use.

Some people taking probiotics may notice mild gastrointestinal side effects like bloating, gas, stomach discomfort, or diarrhea, but these are uncommon. Very rarely, the live organisms can cause serious infections (bacteremia, sepsis, or abscess) in certain patients — this risk is thought to be highest in people with weakened immune systems or serious underlying illness.

There is no pregnancy or breastfeeding safety data on file for any of these ingredients — talk with your pharmacist or doctor for personalized advice if you're pregnant or nursing.

Side effects, ingredient by ingredient Lactobacillus Acidophilus

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lactobacillus Acidophilus.
  • The most serious interaction on file is rated Moderate.
  • For scale: 182 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take antibiotic drugs, talk with your pharmacist about timing — taking them at the same time as this product may reduce how well the probiotic works. We could not check two of the three active ingredients for drug interactions, so run your complete medication list through the checker below.

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 synbiotic is intended for people looking to support gut health with live probiotics and prebiotic fiber. If you're taking antibiotics, space them several hours apart from this product so the antibiotic doesn't kill off the live organisms.

Check with your pharmacist before starting, especially if you have a weakened immune system or serious illness.

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.

Synbiotic by NutriCology Restore-Biotic: Common Questions

Does Synbiotic by NutriCology Restore-Biotic interact with any medications?
Yes. Based on its ingredients, Synbiotic has a known interaction with 182 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Synbiotic contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this with my antibiotic?
Not at the same time. Antibiotics can kill the live bacteria in this product and make it less effective. Ask your pharmacist how many hours apart to take them — usually it's 2 to 3 hours, but it depends on which antibiotic you're on.
Does it really work for IBS or diarrhea?
Lactobacillus acidophilus in this product has possibly effective evidence for IBS, antibiotic-associated diarrhea, and bacterial vaginosis. That means some studies show benefit, but the evidence isn't rock-solid yet. Results vary from person to person.
What are those side effects you mention?
Most people don't notice anything. Some may have mild bloating, gas, stomach discomfort, or loose stools when they first start a probiotic. These are uncommon and usually pass. Very rarely, the live organisms can cause serious infection in people with weakened immune systems — ask your doctor if that's a concern for you.
Is it safe during pregnancy or breastfeeding?
We don't have safety data on file for these specific ingredients during pregnancy or breastfeeding. Talk with your pharmacist or obstetrician for personalized advice before you start.
What's the difference between the probiotics in here?
Lactobacillus acidophilus and Bifidobacterium lactis are both live beneficial bacteria that support gut health in slightly different ways. Together, they aim to create a more balanced microbial community in your intestines.
