Probiotics for women

Vaginal probiotics for women

Bacteria of the genus Lactobacillus are the majority in the vaginal microbiota of healthy women.


These microorganisms that form the vaginal flora live together with the rest of the microbiota in a situation of equilibrium or balance

When for some reason (treatment with antibiotics, use of spermicides, treatment with antineoplastics, etc) an imbalance in the composition of the microbiota occurs, there is an increased risk of infection (Bacterial Vaginosis BV, thrush, trichomoniasis or urinary tract infections UTI, and in this case the use of probiotics plays a very important role in rebalancing the vaginal microbiota and regulating the pH balance of the woman’s vagina.

Both vaginal ovuli and oral capsules have in their composition several freeze-dried species of microorganisms of the genus Lactobacillus, as this is the majority genus that needs to be repopulated.

Let’s look at some of the best probiotics for women we can find in the market

Culturelle Women’s Healthy Balance Probiotic for Women

Probiotic for women with a formula based on species of microorganisms of the genus Lactobacillus which are the majority of the vaginal microbiota.

It has a total of 15 billion microorganisms from the strains Lactobacillus crispatus LBV 88, Lactobacillus rhamnosus LBV 96, Lactobacillus rhamnosus GG, Lactobacillus gasseri LBV 150N, Lactobacillus jensenii LBV 116.

These strains are common in the microbiota or vaginal flora and have demonstrated their effectiveness in recovering and maintaining its balance as well as in the treatment of different types of bacterial vaginosis (BV) with a decrease in the Nugent index.

The presence of Lactobacillus rhamnosus GG (LGG®) in its formula stands out. It is a well known species and one of the most studied, with about 1000 studies conducted on it and about 200 clinical trials. It has beneficial properties for the intestinal microbiota, favoring its protection and creating a hostile environment for pathogenic microorganisms. Also, this species Lactobacillus rhamnosus GG® stimulates the immune system.

Culturelle is a brand belonging to i-Health, Inc, a global consumer health and wellness American company.

AZO Complete Feminine Balance Daily Probiotics for Women

Like the previous Culturelle probiotic, AZO Complete Feminine Balance is owned by the same company, i-Health, Inc. In fact, both have virtually the same probiotic formula. The AZO Complete Feminine Balance formula has 4 probiotic strains: Lactobacillus crispatus LBV 88, Lactobacillus rhamnosus LBV 96, Lactobacillus gasseri LBV 150N, Lactobacillus jensenii LBV 116 and has 5 billion microorganisms versus 15 billion of its equivalent in Culturelle.

The properties of the product are similar to the previous one although, as it has a lower probiotic load, it is more recommendable if you have never tried a probiotic and this is the first time you are taking it.

RepHresh Pro B Probiotic for women

RepHresh Pro-B is a probiotic for women with 2 patented strains clinically verified to maintain a healthy vaginal flora.

This probiotic for women contains in its formula Lactobacillus rhamnosus GR-1® and Lactobacillus reuteri RC-14, two strains generally studied together to analyze the beneficial effect that both strains have on women’s intimate health.

The Lactobacillus rhamnosus GR-1® strain has studies that demonstrate its ability to improve the balance of a woman’s vaginal microbiota. It is a strain that helps protect the female urogenital area from infections such as bacterial vaginosis (bv) and other urinary tract infections such as cystitis. Its mechanism of action is based on the adherence of these “good” microorganisms to the vaginal mucosa, displacing possible pathogenic microorganisms (1)

In addition, as a lactobacillus, it produces lactic acid, reducing the vaginal pH to get a women’s ph balance and thus preventing colonization by pathogenic bacteria capable of producing an infection, since these microorganisms prefer a more alkaline environment with a higher pH.

For its part, Lactobacillus reuteri RC-14® has studies that demonstrate its beneficial activity against Candida albicans, responsible for the infection known as candidiasis, yeast infection or thrush (2)

Lactobacillus reuteri RC-14® also acts against bacterial vaginosis, a condition with a whitish exudate and a characteristic “fishy odor”. There is usually also an itching and burning sensation.

In a study carried out with Lactobacillus reuteri RC-14® together with Lactobacillus rhamnosus GR-1® in 544 women, it showed the benefits that these two strains have in the treatment of bacterial vaginosis (bv) (3)

It also has a component called elevATP® which consists of a combination of apple and peat polyphenols that promote the production of ATP (Adenosine tri-phosphate) the cellular energy source.

Finally, we should mention the presence in its formula of Changa mushroom, with several beneficial effects for health among which are its effect in reducing the levels of cholesterol and sugar (4)

This species, Lactobacillus acidophilus is one of the most studied species and with more clinical trials carried out. It enhances the balance of both vaginal and intestinal microbiota.

OptiBac, manufactured in UK by Wren. They are capsules with 2.3 billion of Lactobacillus reuteri RC-14 ® and Lactobacillus rhamnosus GR-1 ®. That is, they are the same microorganisms that we have already seen in other products on this same page and at a lower price. Like other probiotics with the same composition, they are suitable for the treatment of bacterial vaginosis (BV), urinary tract infections (UTI) as well as vaginal candidiasis, yeast infection or thrush.

As mentioned above, these Lactobacillus reuteri RC-14 ® and Lactobacillus rhamnosus GR-1 ® strains are registered by CHR HANSEN. They are two of the strains on which most studies have been carried out both in vitro and in vivo. They have the security of being within the QPS list and being recognized as GRAS (Generally Recognized As Safe) microorganisms by the FDA, that is to say, safe and innocuous strains.

Women’s Probiotic 20 Billion

This product gathers 3 strains of probiotic bacteria: Lactobacillus rhamnosus HN001, Bifidobacterium lactis HN019, Lactobacillus acidophilus La-14®

There are several studies that demonstrate the beneficial properties of these bacteria – in combination or separately – on women’s health.

Lactobacillus rhamnosus HN001 improves immunity in pregnant women (9). Studies have also been done together with Bifidobacterium lactis HN019 comparing its activity against a placebo and showing its protective immune effects (10).

Other studies have shown how the combination of Lactobacillus rhamnosus HN001 and Lactobacillus acidophilus LA14 promotes the growth of these Lactobacilli in the vagina (11) and, in cases of candidiasis, yeast infection or thrush it inhibits the growth of Candida albicans, also reducing the symptoms and probability of recurrence when administered together with antifungal treatment (12).

Vaginal Suppositories

In addition to oral administration, vaginal probiotics can be found on the market in the form of suppositories or ovuli to be introduced directly into the vagina.

Some of them are:

Vagi Biom Probiotic Suppositories

These are vaginal suppositories that each contain a total of 1×1010 cfu of the strains Lactobacillus acidophilus Bi14, Lactobacillus crispatus Bi16, Lactobacillus gasseri Bi19 and Bacillus coagulans Bi34 which will allow the re-establishment of the vaginal flora of this genus of lactobacilli.

It is important not to confuse this type of probiotics with other vaginal ovules which, although effective and indicated for reducing the pH of the vagina and lubricating its epithelium, do not contain microorganisms in their formula, i.e. they are not probiotics.

FloraFemme – pH Balanced Vaginal Probiotic Suppositories

Probiotics in suppositories to be administered directly into the vagina. It has a total of 72 billion “good” bacteria, with a total of 11 different species, most of which are of the genus Lactobacillus, making it one of the best probiotics for women’s ph balance.
