The benefits of probiotics for women

When most people think of probiotics, they think of the gut. And that makes sense, probiotics are best known for their role in improving gut health and indirect benefits on the immune system. But when it comes to the benefits of probiotics for women, there’s another important microbiome to consider: the vagina.

Vaginal health has received very little mainstream attention. Thankfully, this is changing, and researchers are slowly learning more about the delicate balance of bacteria that makes up the vaginal microbiome. This includes the potential use of probiotics in promoting women’s health. This exciting research has shown that certain probiotics may help to prevent and manage common gynaecological infections like recurring thrush, bacterial vaginosis (BV), and urinary tract infections (UTIs). If you, like many women, experience these common infections then it may be time to explore a specialised probiotic solution.

Why vaginal health matters more than you think

Like the gut, the vaginal microbiome is a unique ecosystem made up of different kinds of bacteria and fungi. When these microorganisms are in balance, they work together to maintain an ideal environment. Lactobacillus strains are the most prominent bacteria in a healthy system and play a big role in maintaining balance.

Lactobacillus is also in charge of maintaining the pH of the vagina. Ideally slightly acidic, with a pH around 3.8 to 4.5, the vaginal microbiome can keep bad bacteria and yeast growth under control.

But factors like stress, hormonal changes, menstrual cycles, certain hygiene products, tight clothing, and especially antibiotics can disrupt this balance. When the good bacteria are depleted, your chances of developing conditions like thrush, BV, or a UTI increase.

Thankfully, there are certain probiotics, like Reuterina Femme, specifically designed to tackle this problem. Below we have unpacked how a probiotic can help keep each of these conditions at bay, demonstrating the benefits of probiotics for vaginal and urinary health support.

Probiotics and BV (bacterial vaginosis)

What is BV?

BV is a common complaint, affecting around 30% of women. It is caused by an overgrowth of certain bacteria like Gardnerella, made possible by a change in pH. This usually occurs alongside a decrease in Lactobacillus bacteria.

How can you use probiotics to treat BV?

Probiotics are not a treatment for BV. However, they can help, especially those that contain Lactobacillus strains. This is due to the role these strains play in maintaining pH. Probiotics like Reuterina Femme help to reintroduce and maintain healthy levels of Lactobacilli, indirectly helping to restore a normal pH and stop the overgrowth of infection-causing bacteria. Another benefit of Reuterina Femme specifically is its ability to improve the effectiveness of antibiotic medications that form the primary treatment for BV infections.

Probiotics and Thrush

What is thrush?

Vaginal thrush is caused by the overgrowth of a yeast that occurs naturally in the vagina, most commonly Candida yeast. It is extremely common, and around 75% of women will experience it at some point in their lifetime. Some women experience recurring thrush. These infections can be brought on by hormonal changes due to birth control, their menstrual cycle, or a health condition like diabetes.

How will a probiotic help with thrush?

Probiotics in the form of yogurt have been used to help with thrush for centuries. This is due to the presence of Lactobacillus bacteria in yogurt. Thankfully, the dawn of oral and suppository probiotics means there is a far less messy solution. In addition to maintaining pH, Lactobacillus is also responsible for keeping the growth of yeast like Candida at bay, keeping everything in check. Certain probiotics help to not only to support this balance, but they have also been found to improve the effectiveness of the anti-fungal creams usually used to treat an infection.

What about UTIs?

The relationship between these nifty supplements and UTIs is slightly different. E. coli, the bacteria responsible for most UTIs, is not one that occurs naturally in the vagina. Rather, it is introduced into the vagina from an external source. This means that a UTI cannot be caused by a poorly balanced vaginal environment. However, as we have established, Lactobacillus acts almost as the hall monitor for the vagina, keeping everyone in line. But it can also be a security guard, protecting against intruders. This is the case with UTIs. While a balanced microbiome may not mean you are immune from a UTI, having healthy, balanced vaginal flora can help protect from infections, including UTIs.

What is a good probiotic for women?

Like all supplements, different probiotics have different intended benefits. The best probiotic for women is one that is specially designed for vaginal health. This generally means finding one that contains Lactobacillus strains. Secondly, very few probiotics are backed by clinical research. Look out for an option that has undergone clinical trials to prove its effectiveness.

One option that fulfils all these criteria is Reuterina Femme. Part of the larger Reuterina range, this probiotic contains strains specifically selected to promote women’s health. Furthermore, Reuterina is clinically proven to work, having been clinically validated by over 250 clinical trials. 

Clearly, the benefits of probiotics for women go beyond digestion, helping to not only support your immune system, but also protect against and help to resolve common gynaecological conditions. From feeling the benefits of probiotics on BV to helping with thrush prevention, a targeted probiotic like Reuterina Femme can be a simple, daily step toward better health.
