But Really, Though — What's The Big Difference Between Women's & Men's Probiotic Formulas?

It's safe to say that in nearly every aspect of life, women and men have some major differences between them. When it comes to health, gender is a front-and-center factor at pretty much every phase of clinical study. So, it's surprising that there's not a whole lot of published studies that differentiate between men and women in the world of probiotics.

For some context: More and more research on the microbiome—aka the trillions of bacteria and other microbes that take up residence in our body—is linking the health of our gut to everything from immunity to mood to clear skin to brain health and beyond. You could argue that supporting healthy bacteria levels with probiotics, whether through probiotic-rich foods or daily supplements, is practically the new normal in the modern wellness routine.

When it comes to the gut stuff, women really get the short end of the stick. Case in point: Constipation, IBS1, and other gastrointestinal issues are all more common in women than in men—not to mention it's just normal to experience bloating and changes in bathroom habits at different points in a woman's cycle thanks to hormones in flux.

Stress is a common factor that causes IBS and digestive discomfort, and for women, stress is no small thing. A survey by the American Psychological Association found that women are more likely than men to feel stressed out and experience physical and emotional symptoms related to stress—everything from getting a headache, feeling like they could cry, and (yup) having an upset stomach or indigestion.

Almost half of all women (49%) reported that their stress has risen in the last five years, compared to 39% of men. And the stress gap gets bigger when it comes to emotional labor, a term coined by sociologist Arlie Hochschild in the 1980s that refers to the work someone does that goes unnoticed, whether professionally, in relationships, or at home.

This one is specifically women-only, and it's nothing to be embarrassed about: 75% of all women will have a yeast infection (also known as candida overgrowth) down there at some point in their lives—scientists even estimate that one in five women3 normally have a vaginal yeast infection but without any symptoms. It's one of the biggest reasons a gender-specific formula holds some serious weight.

Probiotics for women are often recommended to prevent yeast overgrowth by promoting a healthy balance of gut microflora—but there are tons of extra benefits of having a healthy vaginal microbiome (think fertility health and fewer bladder infections, too). Lactobacilli are the most prevalent good bacteria found in a healthy vagina and urinary tract, so look for a women's probiotic with plenty of Lactobacillus strains to keep all the signs (and, yep, smells!) of a healthy vag going. The Ultimate Flora Women's Care Probiotic from RenewLife is mostly a Lactobacilli formula (specifically containing strains of Lactobacillus acidophilus shown to colonize4 the vagina) that's designed to help support vaginal health and fight yeast infections.
