HelloPharmacist Scorecard of Flora Synergy by Energetix

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Flora Synergy contains 2 active ingredients. Fructooligosaccharides (FOS) is a carbohydrate that acts as a prebiotic — food for your good gut bacteria.

Bacillus coagulans is a live, spore-forming probiotic strain that's meant to support your digestive tract. The capsule also contains inactive ingredients including cellulose, purified water, maltodextrin, and medium chain triglycerides — standard excipients to hold and deliver the active components.

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: Supports healthy intestinal and immune function.
  • We looked for evidence on: Constipation, Diarrhea, Dyspepsia, Flatulence, Irritable bowel syndrome (IBS), Upper respiratory tract infection (URTI) — and 3 related terms.
  • The strongest evidence on file: Bacillus Coagulans is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Bacillus Coagulans is rated "Possibly Effective" for Irritable bowel syndrome (IBS).
  • Also on file: Fructo-oligosaccharides (fos) is rated "Insufficient Reliable Evidence To Rate" for Constipation, Travelers' diarrhea.

The evidence for what this product can do varies by ingredient. Bacillus coagulans is possibly effective for constipation and irritable bowel syndrome (IBS), meaning some evidence supports its use but more high-quality research is needed.

For antibiotic-associated diarrhea, athletic performance, cancer, and fatty liver disease, the evidence isn't established. Fructooligosaccharides have insufficient reliable evidence to rate for osteoporosis, constipation, diabetes, traveler's diarrhea, and high cholesterol.

In other words, we don't yet know if it works well for those uses.

The evidence, ingredient by ingredient Fructo-oligosaccharides (fos) Bacillus Coagulans

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both ingredients are generally well tolerated. FOS can cause gas, bloating, abdominal pain, and flatulence — especially at higher doses — though studies show that at doses under 10 grams per day, these effects are typically mild and don't occur more often than with placebo.

Bacillus coagulans is generally well tolerated in healthy adults, but safety data is limited and product quality varies across brands. There's theoretical concern that live probiotics could cause infection in people who are severely ill, immunocompromised, or have central lines, though this is rare in people with intact immune systems.

For pregnancy and lactation, data on file is incomplete — talk with your doctor or pharmacist for personalized advice before use.

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 2 matched ingredients can interact with medications — Bacillus Coagulans.
  • 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.

Antibiotics are the main concern. If you're on any antibiotic, separate it from Flora Synergy by several hours or talk to your pharmacist about the best timing.

No other medication interactions are documented for the ingredients we could check.

The bottom line

Antibiotic Drugs

Theoretically, taking antibiotics with Bacillus coagulans might decrease the effectiveness of B. coagulans.
B. coagulans 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 B. coagulans preparations by at least two hours.

Flora Synergy by Energetix: Common Questions

Does Flora Synergy by Energetix interact with any medications?
Yes. Based on its ingredients, Flora Synergy 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?
Flora Synergy contains 2 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.
Will this help my IBS or constipation?
Bacillus coagulans, one of the two ingredients, is possibly effective for both — meaning some evidence supports it, but we'd like to see more research. Results vary from person to person, so it may take a few weeks to notice a difference.
What's the difference between a probiotic and a prebiotic?
Bacillus coagulans is a probiotic — live beneficial bacteria meant to colonize your gut. Fructooligosaccharides is a prebiotic — food that feeds the good bacteria already in your system. This product gives you both.
Will this cause bloating or gas?
FOS can cause bloating, gas, abdominal pain, and flatulence, especially at higher doses. But studies show that at lower doses (under 10 grams daily), these side effects are usually mild and no more common than placebo.
Can I take this while pregnant or breastfeeding?
We don't have enough safety data on file to say one way or the other for either ingredient. Talk with your doctor or pharmacist — they can weigh what we know and help you decide what's best for you.
I'm on antibiotics. Can I take this at the same time?
No — the antibiotic may kill the live organisms in this probiotic, making it less effective. Separate them by a few hours, or ask your pharmacist for the best timing with your specific antibiotic.
Are there fillers in this?
The capsule contains inactive ingredients: cellulose, purified water, maltodextrin, and medium chain triglycerides. These are standard binders and carriers to help deliver the active ingredients.
