Probiotic CFU Count: What It Means and Why the FemiPro Label Leaves It Out
A probiotic CFU count is the number of colony-forming units, or live cells that can multiply, in one dose. The FemiPro label prints no CFU count. It gives only a 50 mg Probiotic Blend of five strains, and weight cannot be turned into cells, so the number of live bacteria per capsule is unknown.

The term01
What does a probiotic CFU count mean?
A CFU count means colony-forming units: the number of live microbes in a dose that can grow into a colony. It counts living cells, not grams.
That is why a probiotic label often shows a figure in the millions or billions. The figure is the only direct hint of how many live cells you swallow. Two capsules can weigh the same and hold very different numbers of living bacteria, because cells die in storage and heat.
A bigger count is not always better, and a label with no count is not always weak. Effects are strain-specific, and for most conditions researchers do not know which probiotics help or how much to take (NCCIH, Probiotics: usefulness and safety).
Weight is not cells02
Can 50 mg of probiotic strains be turned into CFU?
No, 50 mg of probiotic strains cannot be turned into a CFU count. The milligrams include the dried powder and any carrier, and the cell density of that powder is set by the maker and never printed.
A gram of probiotic culture can carry billions of CFU, so the true count could be large or small. Without the maker's figure, any number you read online is a guess.
FemiPro puts five strains into a "Probiotic Blend" of 50 mg per capsule. The blend line is the only amount shown.
| Detail | On the label? |
|---|---|
| Blend weight (50 mg per capsule) | Yes |
| Names of the five strains | Yes |
| Weight of each strain | Not printed |
| CFU count per capsule | Not printed |
| CFU at the end of shelf life | Not printed |
The nine lines03
Where does the probiotic sit among the nine lines?
The probiotic blend is the smaller of the two blends: 50 mg beside a 350 mg herbal blend. Per capsule, listed blend totals 400 mg, so probiotics are one eighth of the weight.
Inside the 50 mg, the strains come in weight order. Each may weigh at most 50, 25, 16.7, 12.5 and 10 mg for lines one to five. Those are ceilings from the label order, not amounts (21 CFR 101.36, supplement labeling).
| Label line | Blend and place | Most per capsule | Amount used in research | Evidence |
|---|---|---|---|---|
| Mimosa pudica Seed Extract | UTI Herbal Blend, line 1 | at most 350 mg | No human dose established (Muhammad 2016, Mimosa pudica review) | Traditional use and lab data; no human bladder trial |
| Cranberry Extract (Vaccinium macrocarpon) (berry) (std. to 30% proanthocyanidin) | UTI Herbal Blend, line 2 | at most 175 mg | Trials used many juices, tablets and doses; no single PAC dose is set (Cochrane 2023, cranberries for preventing UTIs) (NCCIH, Cranberry) | Moderate: fewer repeat UTIs in women prone to them; not a treatment |
| Bearberry (Arctostaphylos uva-ursi) (leaf) | UTI Herbal Blend, line 3 | at most 116.7 mg | EU traditional use: adult women, for no longer than one week (EMA/HMPC, Uvae ursi folium (bearberry leaf)) (LiverTox, Uva Ursi) | Traditional use only; few modern trials |
| Granular Berberine Hydrochloride Extract 8% (bark/root) | UTI Herbal Blend, line 4 | at most 87.5 mg | Usual herbal dose 250-500 mg two or three times a day (Berberine umbrella review, 2023) (LiverTox, Berberine) | Studied for blood sugar and lipids, not for the bladder |
| Lactobacillus crispatus LCr86 | Probiotic Blend, line 1 | at most 50 mg | Trials of a different strain (CTV-05) used vaginal inserts, not capsules (Cohen et al. 2020 NEJM, Lactin-V and bacterial vaginosis) (Stapleton et al. 2011, L. crispatus and recurrent UTI) | Strain LCr86: no published human trial found |
| Lactobacillus acidophilus LA88 | Probiotic Blend, line 2 | at most 25 mg | Studies dose probiotics in CFU, not milligrams (NCCIH, Probiotics: usefulness and safety) | Strain LA88: no published human trial found |
| Lactobacillus plantarum N13 | Probiotic Blend, line 3 | at most 16.7 mg | Studies dose probiotics in CFU, not milligrams (NCCIH, Probiotics: usefulness and safety) | Strain N13: no published human trial found |
| Lactobacillus gasseri LG08 | Probiotic Blend, line 4 | at most 12.5 mg | Studies dose probiotics in CFU, not milligrams (NCCIH, Probiotics: usefulness and safety) | Strain LG08: no published human trial found |
| Lactobacillus casei LC16 | Probiotic Blend, line 5 | at most 10 mg | Studies dose probiotics in CFU, not milligrams (NCCIH, Probiotics: usefulness and safety) (Cochrane 2015, probiotics for preventing UTIs) | Strain LC16: no published human trial found |

See packsWhat to ask04
What should you ask about a missing CFU count?
Ask the seller for the CFU count at the end of shelf life, the date it was tested and the lab that tested it. A fair answer names all three. Dietary supplements need no FDA approval before sale, so the maker carries the duty of truthful labels (NIH ODS, Supplements: What You Need to Know).
The FemiPro order desk is +1 (302) 200-3480. It handles placed orders, so a technical question may take a few tries. The site does not publish a lab report, and the lot and certificate numbers shown on the batch check page are seller references, not proof.
What is the CFU count at the end of shelf life? Which date and lab produced it? Is the count for each strain or for the blend as a whole?
Until a figure arrives, treat the probiotics as present but unmeasured.
Judging it05
How do you judge a probiotic with no CFU count?
Judge it by your own record, not by the label. Note leaks, trips to the bathroom and digestion for two weeks before the first capsule, then compare. Mild stomach changes are the usual effect reported with probiotics.
The firmest advice for leaks does not depend on bacteria at all. Pelvic floor and bladder training lead the list (NIDDK, Incontinence treatment). The supplements and medicines guide covers what to tell your pharmacist. Keep taking any prescribed medicine.

FAQ06
CFU questions, answered
What is a good CFU count for women?
No single number is proven for bladder or vaginal health, because effects depend on the strain. Studies use many different counts. Compare the strain and the trial, not only the size of the number.
Is a bigger CFU number a stronger probiotic?
Not necessarily. A larger count means more live cells at the time of testing, yet strain, survival through the stomach and storage also matter. A smaller dose of a well-studied strain can beat a huge count of an untested one.
Do probiotic capsules need refrigeration?
The FemiPro label says to store the bottle in a cool, dry place and does not call for the fridge. Heat and damp shorten the life of live cultures, so keep the cap tight and away from the stove.
Does the missing CFU count mean FemiPro is fake?
No. Many blends omit it. It means you cannot check the dose of live bacteria yourself. Judge the label as incomplete, not as proof of anything wrong, and weigh it against the missing product trial.
