Here's Why Probiotics For Women Are So Beneficial + How To Pick The Best One

Probiotics seem to offer an ever-expanding list of superpowers.

These beneficial bacteria can help support gut health, digestion, and even emotional well being—just to name a few benefits.

And for women, in particular, probiotics come with a specific set of perks. For starters, women tend to be affected by digestive issues more than men, so keeping this balance of bacteria happy is important.

A healthy microbiome supports overall health in many ways, but unfortunately, there are many things that can disrupt the peace within this little ecosystem.

Chronic stress (which many women are familiar with) can throw the microbiome out of whack, and excess sugar and processed foods also has a negative effect.

Bacterial infections, parasites, and yeast (not the good kind) can also wreak havoc.

And as you might guess, antibiotics are another culprit.

Although sometimes necessary, they do more than just wipe out "bad" bacteria—they disrupt the "good" bacteria1 in the microbiome as well (taking just one course of antibiotics can mess with your gut flora for up to 12 months or longer afterward).

While everyone is susceptible to an imbalanced gut, there are reasons women, in particular, should be thinking about it.

Women report higher levels of stress than men, are more likely to be prescribed antibiotics, and are more likely to suffer from gastrointestinal issues.

When your microbiome isn't in good shape, it can lead to issues like GI distress, allergies, autoimmune issues, skin conditions (like acne and eczema), hormonal imbalances, weight gain, frequent vaginal infections, and more.

Studies suggest that the GI systems of women could be more sluggish than those of men, increasing the risk for digestive issues. Taking a probiotic can promote a healthy gut microbiome and support digestion.

"Think of probiotics as your little helpers that restore order and help maintain harmony in your gut ecosystem," says gut health expert Vincent Pedre, M.D. "They outnumber and antagonize unwelcome pathogens, including unfavorable bacteria, yeast, and parasites."

Infections like bacterial vaginosis (BV) and urinary tract infections (UTI) can occur when bad bacteria inside the vagina outnumber the good. 

"Like the microbiome in our digestive system, sinuses, and skin, the vaginal microbiome is the first line of defense against infections," explains family functional medicine doctor Elizabeth Boham, M.D., M.S., R.D.

Certain probiotic strains can support the vaginal microbiome3, keeping the "bad" bacteria that cause these infections at bay.

According to a review on the influence of probiotics on urogenital infections (like UTIs, BV, and yeast vaginitis), research has found an association between Lactobacilli (one common probiotic strain) presence in the vagina and women who have never had a UTI.

Studies have also found that probiotics and weight management are connected, specifically in women.

In one study, researchers found that overweight women who underwent a weight loss diet for 12 weeks while taking a certain strain of probiotics lost more weight4 than a group of overweight women who did the same weight loss diet for 12 weeks without taking a probiotic.

The women who took the probiotic also continued to lose weight during the 12-week maintenance period afterward, while the other group's weight remained stable. Interestingly, the researchers did not see the same weight changes in men.

The gut and vagina aren't the only homes of microbiomes in the body. The skin2 is also home to trillions of bacteria.

The nutritional support of probiotics could help manage5 problems like eczema, acne, allergic inflammation, and hypersensitivity, as well as promote wound healing and help fight skin damage.

Different strains have been studied for different applications, so choosing a probiotic that is targeted to your specific needs is important.

While the list of ingredients found on the back of a probiotic can seem confusing or overwhelming, a diverse probiotic will likely contain Lactobacillus and Bifidobacterium bacteria (and various species within each of those strains, like Lactobacillus acidophilus and Bifidobacterium lactis).

The quality and quantity of a probiotic should also be involved in your decision.

Quality-wise, to make sure a probiotic contains what it says it does—and that those live bacteria actually make it from production to your intestines without dying off—look for professional brands that undergo third-party testing.

And when it comes to quantity, look for a product in the billions of CFUs (or colony-forming units).

Probiotics often range from 5 to 100 billion, and you should start on the lower end and increase as they're tolerated (it's also worth noting that the more gut damage, the more CFUs you might need in the appropriate setting).

If you're looking for a probiotic to address your issues, consider talking to an integrative or functional medicine doctor or health care professional. They may be able to point you in the direction of which probiotic for women is best for you.
