FemiCore's Other Four Probiotic Strains, Explained
The FemiCore probiotic strains after L. crispatus are L. acidophilus LA88, L. plantarum N13, L. gasseri LG08 and L. casei LC16: lines 2 to 5 of a 50 mg blend. Label order caps them at 25, about 17, 12.5 and 10 mg. No CFU count is printed, and we found no published trial for any of these four strain codes.

Strains 2 to 5
What are the FemiCore probiotic strains besides L. crispatus?
The FemiCore probiotic strains besides L. crispatus LCr86 are four lactic acid bacteria: L. acidophilus LA88, L. plantarum N13, L. gasseri LG08 and L. casei LC16. They fill places 2, 3, 4 and 5 of the 50 mg probiotic blend.
All four are common species in foods. None of their four codes turned up in a published trial when we searched in October 2026.
A note on the spelling
The sales page writes "Cassei"; the label's casei is the correct species name.
L. crispatus, the first strain, has its own L. crispatus LCr86 profile.
Ceilings
How much of each strain is in one FemiCore capsule?
Each of these strains weighs at most 25, about 17, 12.5 and 10 mg, in that order. Those are ceilings from label order, not measured amounts (21 CFR 101.36, supplement labeling).
One more step: line 1 is at least the average of all five, so L. crispatus holds at least 10 mg, leaving at most 40 mg for the other four together.

The four species
What is known about L. acidophilus, L. plantarum, L. gasseri and L. casei?
Each species has a long record in food, but that record is not about these four codes. Two of the four now carry new genus names after a 2020 reshuffle of the Lactobacillus group; labels often keep the old ones.
| Label name | Current name | Often found in | Trial of this code |
|---|---|---|---|
| L. acidophilus LA88 | Lactobacillus acidophilus (unchanged) | Yogurt cultures, the gut | None found |
| L. plantarum N13 | Lactiplantibacillus plantarum | Pickles, sauerkraut, sourdough | None found |
| L. gasseri LG08 | Lactobacillus gasseri (unchanged) | The gut and the vagina | None found |
| L. casei LC16 | Lacticaseibacillus casei | Cheese and fermented milk | None found |
Strain codes
What do the codes LA88, N13, LG08 and LC16 mean?
Each code names one line within a species, kept by a culture supplier. Results belong to one strain at a time (NCCIH, Probiotics).
GenusLactobacillus
Speciescrispatus
Strain codeLCr86
A probiotic's effect belongs to the strain, the code after the species name, not to the species in general (NCCIH, Probiotics) (NIH ODS, Probiotics). Two strains of one species can behave differently, so research on "L. crispatus" in general does not transfer to LCr86.
| Strain on the label | Place | Most per capsule | Strain-level research we found | Caution |
|---|---|---|---|---|
| Lactobacillus crispatus LCr86 | 1 of 5 | at most 50 mg | One registered trial gave 10 billion CFU a day orally (vaginal outcome) | Ask first if your immune system is weakened. |
| Lactobacillus acidophilus LA88 | 2 of 5 | at most 25 mg | No published trial found for this strain code | Ask first if your immune system is weakened. |
| Lactobacillus plantarum N13 | 3 of 5 | at most 16.7 mg | No published trial found for this strain code | Ask first if your immune system is weakened. |
| Lactobacillus gasseri LG08 | 4 of 5 | at most 12.5 mg | No published trial found for this strain code | Ask first if your immune system is weakened. |
| Lactobacillus casei LC16 | 5 of 5 | at most 10 mg | No published trial found for this strain code | Ask first if your immune system is weakened. |
Searched October 2026. LCr86 has one completed placebo trial (80 women, 10 billion CFU a day by mouth, 8 weeks, vaginal Nugent score) with no results posted (ClinicalTrials.gov NCT06830122, LCr86). "Lactobacillus" species were renamed in 2020 (for example L. casei is now Lacticaseibacillus casei); labels often keep the old names.

See packsLive cells
Why does the missing CFU count matter?
The missing CFU count matters because a probiotic has to be alive to work, and weight cannot show how many cells are alive. CFU means colony-forming units, cells able to grow.
NIH notes that label weight includes dead cells and advises a CFU count stated for the end of shelf life (NIH ODS, Probiotics). FemiCore gives only 50 mg for five strains. Ten milligrams could be billions of live cells or almost none.
For scale, the one LCr86 trial gave 10 billion CFU a day (ClinicalTrials.gov NCT06830122, LCr86); with no count on the bottle, nothing compares.
Safety
Are these probiotic strains safe to take?
For most healthy adults these species have a long record of apparently safe use, but risk rises with severe illness or a weak immune system (NCCIH, Probiotics). Rare serious infections have happened mostly in very ill patients (NIH ODS, Probiotics).
The FDA's 2023 warning concerned preterm infants, not adult women (FDA 2023, probiotics in preterm infants). The label asks anyone pregnant, nursing, under 18 or with a medical condition to see a physician first. Keep taking prescribed medicine; a probiotic does not replace it. More cautions are on FemiCore side effects.
Dairy and storage
Do the FemiCore strains contain dairy, and do they need the fridge?
No dairy ingredient is listed on the FemiCore label, and the bottle asks for a cool, dry place, not a fridge. Some probiotics do need refrigeration (NIH ODS, Probiotics); a cool cupboard is the sensible spot.
No allergen test is published. With a severe milk allergy, ask the seller first.

FAQ
FemiCore strains: questions
Is it L. casei or L. cassei in FemiCore?
It is L. casei. The bottle's Supplement Facts panel prints Lactobacillus casei LC16, the correct scientific spelling. The sales page writes "Cassei", which is a typo rather than a different organism. When the label and the sales page disagree, we follow the label, because the label is what ships in the box.
Why do some sites call these strains by different genus names?
In 2020 microbiologists split the old Lactobacillus genus into many smaller groups. L. plantarum became Lactiplantibacillus plantarum and L. casei became Lacticaseibacillus casei, while acidophilus and gasseri kept the old name. Labels, FemiCore's included, often still use the older names, so both spellings point to the same species.
What does a strain code like N13 tell you?
It names one specific line within a species, the way a cultivar names one variety of apple. Effects found for one strain do not carry over to another of the same species. To judge N13 you would need studies of N13 itself, and we found none published as of October 2026.
How many live cultures are in a FemiCore capsule?
Nobody outside the maker can say, because the label prints no CFU count. It gives only a 50 mg weight for all five strains, and that weight includes dead cells. NIH advises choosing products that state a CFU count for the end of shelf life, which FemiCore does not.
Are FemiCore's probiotics safe with a milk allergy?
No dairy ingredient appears on the label, but no allergen test is published either, and L. casei is often grown for dairy use. If your milk allergy is severe, ask the seller about allergen controls before you order, and check with your allergist.
Should FemiCore capsules be kept in the refrigerator?
The label does not ask for it; it says to store the bottle in a cool, dry place. Heat and damp harm live cultures, so avoid a sunny windowsill, a hot car or a steamy bathroom. Close the cap tightly after each capsule.
