HelloPharmacist Scorecard of SBO Probiotics Once Daily Vaginal by Ancient Nutrition

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
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 0 of its 8 active ingredients.
  • “SBO Once Daily Blend” is a proprietary blend — the label gives one combined amount (245 mg) without saying how much of each component you get.
  • “Vaginal Support Blend” is a proprietary blend — the label gives one combined amount (310 mg) without saying how much of each component you get.

This product contains 8 ingredients, including three live bacterial strains — Bacillus coagulans, Bacillus clausii, and Bacillus subtilis — plus the beneficial yeast Saccharomyces boulardii, all designed to support vaginal flora. It also includes Cranberry (for urinary tract health), organic Apple Cider Vinegar, organic Reishi Mushroom, and Chaste Tree (Fermented).

Two of these are blended groups — the SBO Once Daily Blend and Vaginal Support Blend — whose exact proportions are part of the product's formula. The remaining ingredients are inactive: hypromellose, acacia gum, and organic carnauba wax, which make up the capsule and help hold it together.

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: promote healthy yeast balance and vaginal health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Clostridioides difficile infection, Constipation, Diarrhea, Flatulence, Inflammatory bowel disease (IBD) — and 3 related terms.
  • The strongest evidence on file: Saccharomyces Boulardii is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Saccharomyces Boulardii is rated "Possibly Effective" for Rotaviral diarrhea, Travelers' diarrhea, Clostridioides difficile infection.
  • Also on file: Bacillus Coagulans is rated "Possibly Effective" for Constipation.

Evidence for this product's purposes comes ingredient by ingredient. Bacillus coagulans is possibly effective for constipation and irritable bowel syndrome (IBS), though the data on antibiotic-related diarrhea isn't strong enough to rate.

Saccharomyces boulardii is possibly effective for traveler's diarrhea, antibiotic-associated diarrhea, and a few other types of infectious diarrhea. Cranberry is possibly effective for urinary tract infections.

Reishi Mushroom appears possibly ineffective for high cholesterol. For the other claimed uses in this product — athletic performance, cancer prevention, cognitive decline, and others — the evidence we hold is insufficient to rate them.

Bacillus clausii and Chaste Tree haven't been rated in our data.

The evidence, ingredient by ingredient Bacillus Coagulans Saccharomyces Boulardii Bacillus Subtilis Cranberry Apple Cider Vinegar Reishi Mushroom

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bacillus coagulans and Saccharomyces boulardii are generally well tolerated in healthy adults, though both carry a rare but serious risk: if you're critically ill, immunocompromised, have central lines, or are a premature infant, fungal or bacterial infection from these live organisms has been reported. Cranberry is generally well tolerated in food amounts and likely safe in pregnancy and while breastfeeding, though concentrated supplement doses haven't been studied well; side effects in higher doses include diarrhea and stomach upset.

Apple Cider Vinegar is safe in food amounts but rare serious effects from long-term large doses include low potassium, bone loss, and osteoporosis. Reishi Mushroom is generally well tolerated short-term but not studied long-term; safety data is insufficient for pregnancy and breastfeeding.

Common side effects from Reishi include dizziness, dry mouth, nausea, and rash. Bacillus subtilis is generally well tolerated but carries the same rare infection risk as other live bacterial probiotics in vulnerable patients.

We hold no safety data for Bacillus clausii or Chaste Tree.

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?
  • 6 of the 6 matched ingredients can interact with medications — Saccharomyces Boulardii, Apple Cider Vinegar, Reishi Mushroom, Cranberry, Bacillus Coagulans, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,183 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.

Check these medication types before taking this product: antibiotics (Bacillus coagulans and Bacillus subtilis may be less effective if taken at the same time — separate them by a few hours), drugs your liver breaks down like atorvastatin and nifedipine (Cranberry may raise their levels), blood thinners including warfarin (Cranberry and Reishi may increase bleeding risk), blood pressure medications (Apple Cider Vinegar and Reishi may lower it further), diuretics and digoxin (Apple Cider Vinegar may lower potassium dangerously), insulin and diabetes drugs (Apple Cider Vinegar and Reishi may lower blood sugar more), and antifungals (Saccharomyces boulardii may not work as well). No interactions are documented for the ingredients we could not check.

Cranberry6 drug types · 714 drugs

Atorvastatin (Lipitor)

Theoretically, cranberry might increase levels and adverse effects of atorvastatin.
In one case report, a patient taking atorvastatin experienced upper back pain, rhabdomyolysis, and abnormal liver function after drinking cranberry juice 16 ounces daily for 2 weeks. Theoretically, this may have been caused by inhibition of cytochrome P450 3A4 (CYP3A4) enzymes by cranberry juice, as atorvastatin is a CYP3A4 substrate. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Patients taking atorvastatin should avoid large quantities of cranberry juice.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, cranberry might increase the levels and adverse effects of CYP3A4 substrates.
A case of upper back pain, rhabdomyolysis, and abnormal liver function has been reported for a patient taking atorvastatin, a CYP3A4 substrate, in combination with cranberry juice 16 ounces daily for 2 weeks. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Also, animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine, a CYP3A4 substrate, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Theoretically, cranberry might increase the levels and adverse effects of nifedipine.
Animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine treatment, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, cranberry might increase the levels and adverse effects of warfarin. However, research is conflicting.
There is contradictory evidence about the effect of cranberry juice on warfarin. Case reports have linked cranberry juice consumption to increases in the international normalized ratio (INR) in patients taking warfarin, resulting in severe spontaneous bleeding and excessive postoperative bleeding. Daily consumption of cranberry sauce for one week has also been linked to an increase in INR in one case report. In a small study in healthy young males, taking a high dose of 3 grams of cranberry juice concentrate capsules, equivalent to 57 grams of fruit daily, for 2 weeks produced a 30% increase in the area under the INR-time curve after a single 25-mg dose of warfarin. However, 3 very small clinical studies in patients stabilized on warfarin reported that cranberry juice 250 mL once or twice daily for 7 days (27% cranberry juice or pure cranberry juice) or 240 mL once daily for 14 days does not significantly increase INR or affect plasma warfarin levels. The reasons for these discrepant findings are unclear. It is possible that the form and dose of cranberry may play a role, as cranberry extracts and juices contain different constituents. Additionally, an in vitro study evaluating 5 different cranberry juices found varying effects, with only a cranberry concentrate, and not diluted cranberry juices, inhibiting CYP2C9. However, this concentrate did not inhibit CYP2C9 activity in humans.

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, cranberry might increase the levels and adverse effects of CYP2C9 substrates. However, research is conflicting.
There is contradictory evidence about the effect of cranberry on CYP2C9 enzymes. In vitro evidence suggests that flavonoids in cranberry inhibit CYP2C9 enzymes. However, clinical research shows that cranberry juice does not significantly affect the levels, metabolism, or elimination of the CYP2C9 substrates flurbiprofen or diclofenac. Also, in patients stabilized on warfarin, drinking cranberry juice 250 mL daily for 7 days does not significantly increase the anticoagulant activity of warfarin, a CYP2C9 substrate. Additional pharmacokinetic research shows that cranberry juice does not increase peak plasma concentrations or area under the concentration-time curve of warfarin.

Likelihood Unlikely Evidence B
Diclofenac (Voltaren, Others)

Theoretically, cranberry might modestly increase the levels and adverse effects of diclofenac.
In vitro evidence suggests that cranberry juice inhibits diclofenac metabolism by human liver microsomes. However, drinking cranberry juice does not seem to affect diclofenac metabolism in humans.

Likelihood Unlikely Evidence B
Cranberry full monograph & interactions

organic Reishi3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.

Likelihood Possible Evidence D
organic Reishi full monograph & interactions

Bacillus coagulans1 drug type · 182 drugs

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.

Likelihood Probable Evidence D
Bacillus coagulans full monograph & interactions

Bacillus subtilis1 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Bacillus subtilis with antibiotic drugs might decrease the effectiveness of B. subtilis.
Since B. subtilis 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. subtilis preparations by at least 2 hours.

Likelihood Probable Evidence D
Bacillus subtilis full monograph & interactions

organic Apple Cider Vinegar4 drug types · 162 drugs

Digoxin (Lanoxin)

Theoretically, concomitant use of apple cider vinegar with digoxin might increase the risk of cardiac toxicity.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar could decrease potassium levels, increasing the risk of toxicity with digoxin.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of apple cider vinegar with diuretic drugs might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. There is some concern that people taking apple cider vinegar along with potassium depleting diuretics might have an increased risk for hypokalemia.

Likelihood Possible Evidence D
Insulin

Theoretically, concomitant use of apple cider vinegar with insulin might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar concomitantly with insulin might increase the risk of hypokalemia.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking apple cider vinegar with antidiabetes drugs might increase the risk of hypoglycemia.
Apple cider vinegar might reduce fasting and postprandial blood glucose levels and decrease gastric emptying in people with diabetes. However, not all research agrees. Theoretically, it might have additive effects on glucose levels when used with antidiabetes drugs.

Likelihood Possible Evidence B
organic Apple Cider Vinegar full monograph & interactions

Saccharomyces boulardii1 drug type · 40 drugs

Antifungals

Theoretically, taking antifungals with Saccharomyces boulardii might decrease the effectiveness of Saccharomyces boulardii.
S. boulardii is a live yeast. Therefore, simultaneously taking antifungals might kill a significant number of the organisms.

SBO Probiotics Once Daily Vaginal by Ancient Nutrition: Common Questions

Does SBO Probiotics Once Daily Vaginal by Ancient Nutrition interact with any medications?
Yes. Based on its ingredients, SBO Probiotics Once Daily Vaginal has a known interaction with 1,182 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
SBO Probiotics Once Daily Vaginal contains 8 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 while I'm on antibiotics?
The Bacillus strains in this product may lose effectiveness if you take them at the same time as antibiotics, because the antibiotic can kill the live bacteria. Ask your pharmacist or doctor to space them a few hours apart — for example, take your antibiotic in the morning and this product in the evening.
Is it safe to use during pregnancy?
Cranberry is likely safe during pregnancy. However, the product's data on pregnancy safety for Bacillus coagulans, Bacillus subtilis, Saccharomyces boulardii, Apple Cider Vinegar, and Reishi Mushroom is either not available or too limited — we advise talking with your doctor or midwife before taking it while pregnant.
What does Bacillus coagulans do?
Bacillus coagulans is a probiotic bacterium possibly effective for constipation and IBS. It's a spore-forming live organism meant to support digestive health, though evidence for antibiotic-related diarrhea isn't strong enough to rate.
Will Cranberry help my UTI go away?
Cranberry is possibly effective for urinary tract infections, but it's not a treatment for an active infection — you still need medical care from your doctor if you have a UTI. Use this supplement as a support, not a replacement for antibiotics if prescribed.
What are the most common side effects?
The live organisms may occasionally cause mild stomach upset, gas, or cramps. Cranberry at higher doses can cause diarrhea. Reishi Mushroom commonly causes dizziness, dry mouth, and nausea. Most people tolerate the product well, but if you notice unusual symptoms, talk with your pharmacist.
Can I take this if I'm immunocompromised or in the hospital?
The live bacterial and yeast strains in this product have rarely caused serious infections in critically ill patients, immunocompromised people, or those with central lines. Check with your doctor before using it if you fall into any of these groups.
