FemiPro Probiotics: Five Lactobacillus Strains in 50 mg
FemiPro probiotics are five Lactobacillus strains that share a 50 mg blend in each capsule, led by L. crispatus LCr86. The label prints no count of live bacteria, so each strain averages 10 mg by weight and nothing more is known. Probiotic effects are strain-specific, and we found no human trial of these five strain codes.

The strains01
What probiotics are in FemiPro?
FemiPro's probiotics are five lactic-acid bacteria, all from the Lactobacillus group. The label lists them under "Probiotic Blend" 50 mg, in this order: L. crispatus LCr86, L. acidophilus LA88, L. plantarum N13, L. gasseri LG08 and L. casei LC16.
The letters and numbers after each name are strain codes. They matter, because two strains of the same species can behave differently in the body (NCCIH, Probiotics: usefulness and safety). The label gives the codes but no supplier and no count of live cells.

Blend math02
How much of each strain is in one FemiPro capsule?
Each strain's amount is not printed. The five share 50 mg, listed from most to least by weight (21 CFR 101.36, supplement labeling), so we can only work out ceilings.
The first strain can be at most the whole 50 mg, the second at most half (25 mg), the fifth at most a fifth (10 mg). Split evenly, each weighs 10 mg.
| Place | Strain | Most it could weigh | Live count |
|---|---|---|---|
| 1 | L. crispatus LCr86 | 50 mg | Not printed |
| 2 | L. acidophilus LA88 | 25 mg | Not printed |
| 3 | L. plantarum N13 | 16.7 mg | Not printed |
| 4 | L. gasseri LG08 | 12.5 mg | Not printed |
| 5 | L. casei LC16 | 10 mg | Not printed |
Weight is not live bacteria: a milligram of dried culture can hold very different numbers of living cells.
CFU03
Why does a missing CFU count matter?
A CFU count is the number of living bacteria that can grow into colonies, and it is how probiotic research measures a dose. Without it, you cannot compare FemiPro's 50 mg with any study.
FemiPro prints no CFU figure and no date it holds until. A product can also hold organisms that are not on its label, which is one reason a lab report would help (NCCIH, Probiotics: usefulness and safety).
Ask for the live count per capsule, the date it is counted to, and the certificate for your batch. The FemiPro ingredients overview lists the other gaps on the label.
Crispatus04
What is Lactobacillus crispatus, and why is it first?
Lactobacillus crispatus is a bacterium that often dominates a healthy vaginal microbiome. A study of 396 women found communities led by L. crispatus, L. gasseri, L. iners or L. jensenii, plus a fifth group with fewer lactobacilli (Ravel et al. 2011, vaginal microbiome).
The best crispatus trials used a different strain, CTV-05, placed in the vagina, not swallowed. After treatment for bacterial vaginosis, it cut recurrence by week 12 to 30% against 45% on placebo (Cohen et al. 2020 NEJM, Lactin-V and bacterial vaginosis).
Same species, different product
LCr86 is not CTV-05, and a capsule is not a vaginal insert. Results from one do not carry over to the other.
UTIs05
Do FemiPro's probiotics help prevent UTIs?
No trial shows that FemiPro's strains lower UTI risk. A Cochrane review of nine probiotic studies found no significant drop in repeat UTIs against placebo, and the studies were small (Cochrane 2015, probiotics for preventing UTIs).
The closest result comes from vaginal L. crispatus. In 100 premenopausal women with repeat UTIs, 15% on the suppository had another infection against 27% on placebo, a gap that was not statistically significant (Stapleton et al. 2011, L. crispatus and recurrent UTI).
Lactobacilli in the bladder are linked to fewer urgency symptoms in some studies, but that association does not show a swallowed probiotic helps (Govender 2019, urinary microbiome and UI). The label's "Microbiome Balance" claim cites no study.

Are FemiPro's probiotic strains safe?
For most healthy adults, lactobacilli have a long record of apparent safety; mild gas or bloating is the usual complaint. The risk is higher for anyone with a severe illness or a weakened immune system (NCCIH, Probiotics: usefulness and safety). Ask first if you take drugs that suppress immunity.
The strains come packed with four herbs, so check the whole capsule, not just the probiotics. Bearberry leaf, for one, is meant for courses of no longer than one week (EMA/HMPC, Uvae ursi folium (bearberry leaf)). Keep taking prescribed medicine, including any antibiotic course, exactly as directed.
Storage07
Should FemiPro be refrigerated?
No, the label does not ask for refrigeration. It says: "Store in a cool, dry place." That is the only storage rule printed.
Dried bacteria last longest away from heat and damp. Close the cap after each capsule, leave any moisture packet inside, and skip the bathroom shelf.
FAQ09
Probiotic strains questions
What is Lactobacillus crispatus?
It is a lactic-acid bacterium that often leads a healthy vaginal microbiome. FemiPro lists strain LCr86 first in its probiotic blend. Most published crispatus research used a different strain, CTV-05, given as a vaginal insert, so those results do not transfer to a swallowed capsule.
How many CFU are in FemiPro's probiotics?
The label does not say. It prints only a 50 mg blend weight for all five strains, with no live count and no date. Weight cannot be converted into CFU, so the dose of living bacteria in each capsule is unknown.
Do oral probiotics reach the vagina?
That is not settled, and it likely varies by strain and by person. The strongest crispatus trials skipped the gut and placed the bacteria directly in the vagina. No study has tracked FemiPro's strains.
Do probiotics prevent UTIs?
The evidence is weak. A Cochrane review found no significant drop in repeat UTIs with probiotics against placebo. A vaginal crispatus trial showed fewer repeats, 15% against 27%, but the gap was not statistically significant, and it used a different strain and route.
Should FemiPro be refrigerated?
No. The label says to store it in a cool, dry place and gives no fridge instruction. Keep the cap closed, keep the bottle away from steam and heat, and leave any moisture packet inside to protect the dried cultures.
Can I take FemiPro with antibiotics?
Ask your prescriber or pharmacist first, and finish the antibiotic exactly as directed. Antibiotics can kill probiotic bacteria, so people often space the two a few hours apart, but no timing has been tested for FemiPro. Never use a probiotic in place of an antibiotic.
