HelloPharmacist Scorecard of UltraFlora Spectrum by Metagenics

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 7 active ingredients.
  • “A Proprietary Blend of” is a proprietary blend — the label gives one combined amount (314.75 mg) without saying how much of each component you get.

UltraFlora Spectrum contains 7 active ingredients, all live bacteria and yeast strains intended to support digestive health. The key strains are Saccharomyces boulardii (a probiotic yeast), Lactobacillus acidophilus, Streptococcus thermophilus, and four Bifidobacterium and Lactobacillus species.

The product also contains several inactive ingredients—cellulose, silica, and other binders and capsule materials—that help hold the formula together. Because this is a live-culture supplement, the organisms must survive your digestive tract to be effective.

The strains included here have been studied for a range of digestive and immune-related purposes.

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: probiotic support for digestive and immune health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Clostridioides difficile infection, Diarrhea, Inflammatory bowel disease (IBD), Irritable bowel syndrome (IBS), Lactose intolerance — and 4 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: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea, Irritable bowel syndrome (IBS).

The evidence for UltraFlora Spectrum's strains varies by purpose. Saccharomyces boulardii is rated possibly effective for rotaviral diarrhea, travelers' diarrhea, antibiotic-associated diarrhea, necrotizing enterocolitis, Clostridioides difficile infection, and Helicobacter pylori.

Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, H. pylori, antibiotic-associated diarrhea, and bacterial vaginosis, though it's rated possibly ineffective for atopic disease. Streptococcus thermophilus, however, has insufficient reliable evidence for the uses we hold data on—antibiotic-associated diarrhea, bacterial vaginosis, fatty liver disease, constipation, diabetes, and related kidney complications.

The other three strains in this product have no effectiveness ratings in our data.

The evidence, ingredient by ingredient Saccharomyces Boulardii Streptococcus Thermophilus 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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Saccharomyces boulardii and Streptococcus thermophilus are generally well tolerated in healthy adults, but both should be avoided or used only under medical guidance if you're critically ill or have a weakened immune system (including immunocompromised patients and those in intensive care). Lactobacillus acidophilus is considered generally well tolerated in healthy adults and children.

Rare gastrointestinal side effects—such as abdominal cramps, flatulence, nausea, vomiting, and decreased appetite—have been reported with Saccharomyces boulardii, and uncommonly with Lactobacillus acidophilus when combined with other probiotics. Very rarely, live probiotic bacteria have caused serious bloodstream infections (bacteremia, sepsis) in critically ill or severely immunocompromised patients, particularly those with central lines or indwelling catheters.

Safety data are limited for Bifidobacterium animalis lactis BL-04, Lactobacillus salivarius LS-33, and Lactobacillus plantarum Lp-115.

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?
  • 2 of the 3 matched ingredients can interact with medications — Saccharomyces Boulardii, Lactobacillus Acidophilus.
  • The most serious interaction on file is rated Moderate.
  • For scale: 222 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.

Before taking UltraFlora Spectrum, check with your doctor or pharmacist about any antibiotic drugs you're on—they can kill the live organisms in this product and reduce its benefit. If you take antifungals, the same timing concern applies, though it's less serious.

Ideally, space doses several hours apart. If you're critically ill, hospitalized, or immunocompromised, get medical clearance first.

Check your own medication Run your meds through the checker above

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.

UltraFlora Spectrum is a multi-strain probiotic that may help with diarrhea and digestive complaints if the included strains are effective for your specific situation. If you take antibiotics or antifungal drugs, timing matters—space out doses to keep the live cultures intact.

Avoid this product if you're critically ill or immunocompromised unless your doctor approves. Talk it over with your doctor or pharmacist before starting, especially if you're pregnant, breastfeeding, or have a weakened immune system.

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.

UltraFlora Spectrum by Metagenics: Common Questions

Does UltraFlora Spectrum by Metagenics interact with any medications?
Yes. Based on its ingredients, UltraFlora Spectrum has a known interaction with 222 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
UltraFlora Spectrum contains 7 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.
What is Saccharomyces boulardii, and why is it in this product?
Saccharomyces boulardii is a probiotic yeast included because research suggests it may help prevent or shorten certain types of diarrhea—including traveler's diarrhea, antibiotic-associated diarrhea, and infections like Clostridioides difficile. It's possibly effective for those uses based on available evidence.
Can I take this with antibiotics?
Technically yes, but timing is important. Antibiotics can kill the live bacteria in this product, reducing its effectiveness. Ideally, separate your antibiotic dose from this supplement by several hours—your pharmacist can help you work out the best schedule for your specific medications.
Is this safe if I have a weak immune system?
The data advise caution. Healthy adults generally tolerate these strains well, but if you're immunocompromised, critically ill, hospitalized, or have a central line, there's a small risk of serious infection. Talk with your doctor before starting.
What side effects should I watch for?
Most people tolerate this product without problems. Rarely, Saccharomyces boulardii may cause abdominal cramps, gas, nausea, vomiting, or loss of appetite. Even more uncommonly, the Lactobacillus in the product might cause gas, bloating, or stomach discomfort when combined with other probiotics. These effects are typically mild and temporary.
Will this help my specific digestive problem?
That depends on which strain targets your issue. Saccharomyces boulardii and Lactobacillus acidophilus have the most evidence—both are possibly effective for several types of diarrhea and IBS-related concerns. Streptococcus thermophilus, however, doesn't have reliable evidence for the uses studied. Your doctor can advise whether it's worth trying for your situation.
Is it safe to take during pregnancy or breastfeeding?
Lactobacillus acidophilus and Streptococcus thermophilus are each rated possibly safe in pregnancy, but data are limited and you should check with your doctor first. Safety information for the other strains in pregnancy and lactation isn't on file, so discuss this product with your healthcare provider if you're pregnant or nursing.
