Best Women's Probiotic for Gut and Vaginal Health Together? How to Cover Both
Updated Oct 28, 2026 · 8 sources
Looking for the best women’s probiotic for gut and vaginal health together? Physician’s Choice covers both with two capsules a day. Women’s Probiotic lists 6 strains at 50 billion CFU for the gut, plus cranberry and D-mannose; Vaginal Probiotic lists GR-1™ and RC-14™, a pair tested together by mouth for vaginal flora, plus LBV88™.1,2,3 Our product page says the two are “designed to work side by side.”1
Key points
- In a 2003 placebo-controlled trial in 64 healthy women, GR-1™ with RC-14™ by mouth for 60 days went with a significant rise in vaginal lactobacilli at days 28 and 60 versus placebo.3
- Physician’s Choice lists the six Women’s Probiotic strains with codes, from Lactiplantibacillus plantarum Lp-115® to Bifidobacterium lactis Bl-04®; its label prints the species (See the label).1
- Women’s Probiotic and Vaginal Probiotic are 1 capsule a day each, and the 2003 trial tested its own capsules, not either product (See the label).1,2,3
One probiotic or two for gut and vaginal health?
Two, one built for each job. Probiotics act mainly in the digestive tract, NIH’s Office of Dietary Supplements (ODS) says, while Lactobacillus makes up most of a healthy vaginal flora, Cleveland Clinic explains, and the effects of one probiotic type cannot be assumed for another, NCCIH says.4,5,6 Our Women’s Probiotic and Vaginal Probiotic share no species, so neither label repeats the other’s strains.1,2
Cleveland Clinic lists taking probiotics among the steps that support vaginal flora, citing “some evidence that taking lactobacillus may help improve bacterial balance.”5
Which strains for gut vs vaginal health?
For vaginal flora, Lactobacillus strains; for the gut, Lactobacillus and Bifidobacterium species, which NCCIH lists as the two most common probiotic groups.5,6 Cleveland Clinic says about 95% of the good bacteria in the vagina are lactobacilli, whose lactic acid helps keep vaginal pH slightly acidic.5
GR-1™ and RC-14™ were studied together in a 2003 randomized, placebo-controlled trial in which 64 healthy women took them by mouth for 60 days and researchers measured vaginal flora (Reid and colleagues; RC-14™ was then named L. fermentum RC-14™).3 Cultures showed a significant rise in vaginal lactobacilli at days 28 and 60 compared with placebo.3 Our page on probiotics for vaginal health reports more trials of the pair.
What the strain codes on a women’s probiotic mean
A code names one strain within a species. ODS explains that probiotics are named by genus, species and strain: in Lacticaseibacillus rhamnosus GG, GG is the strain.4
Physician’s Choice lists the Women’s Probiotic strains as Lactiplantibacillus plantarum Lp-115®, Lacticaseibacillus paracasei Lpc-37®, Lacticaseibacillus casei Lc-11®, Lactobacillus gasseri Lg-36™, Lactobacillus acidophilus La-14® and Bifidobacterium lactis Bl-04®. The label and product page print the six species names; the codes come from our company strain list.1 Vaginal Probiotic’s label prints a code after each strain, and its footnote marks GR-1™, RC-14™ and LBV88™ as trademarks, which is what the ® or ™ after a code means.2 Our Vaginal Probiotic strains page takes those three one by one.
Can you take a women’s probiotic and a vaginal probiotic together?
Yes. Our Women’s Probiotic product page answers that question with “they’re designed to work side by side” and tells you to clear any new supplement routine with your doctor first. Each label is 1 capsule a day, so the routine is two capsules daily, and both can be taken with or without food.1,2
A Scientific Advisory Board answer on our product pages says you can combine probiotics, for example one for digestive health and one for vaginal health, and suggests starting one type a few days before adding the next, so you can tell how you feel with each.7

What is the best women’s probiotic for gut and vaginal health together?
Two labels you can check line by line, one for each job. Look for a code after every strain, the CFU count, each other active with its amount, the serving and a storage line. ODS points to the label for each microorganism’s genus, species and strain, its expiration or use-by date and its storage instructions.4 Here are ours, as printed.

Before you start: who should talk to a doctor
Talk to your doctor or ob-gyn about itching, burning, unusual discharge or any other new symptom. ACOG lists itching, burning and a large amount of discharge as possible signs of a vaginal condition, which a doctor diagnoses from a sample of the discharge.8 NCCIH warns against letting a probiotic delay a visit to your health care provider for any health problem.6
If you are pregnant or breastfeeding, are seriously ill, or have a weakened immune system, consult your healthcare provider before taking a probiotic or any other dietary supplement.
If you have known allergies, review the product’s ingredient list and allergen information and consult your healthcare provider before purchasing or using it. Most of our products are formulated without the top 9 common allergens, but ingredients vary by product.
If you experience an adverse event, stop using the product and contact your healthcare provider immediately. Please also notify us at support@physicianschoice.com or 1-877-395-2707.
