Probiotics for Men: Why Guys of All Ages Need Beneficial Gut Bacteria

Probiotics for Men: Why Guys of All Ages Need Beneficial Gut Bacteria

Men, women, and children all benefit from a healthy digestive tract. This is why everyone across genders and all age ranges should take probiotics, either through food or supplement. Probiotics for men are especially important for reasons that go beyond digestion and better times at the loo. We’ll outline some male-specific benefits and list the best probiotics for men based on the latest research.


  • Probiotics Raise Testosterone
  • Probiotics Increase Sex Drive
  • Probiotics Reduce Risk of Prostate Cancer
  • Best Probiotics for Men
  • Probiotics Raise Testosterone

    If you’re a regular UMZU follower or follow other fitness sites, then you probably know that minerals like zinc and magnesium are natural testosterone boosters. Natural T enhancers, though, go beyond minerals and vitamins. Research shows probiotics also elevate male hormones. In turn, this increases sex drive, which we discuss in the next section.

    One study1 showed that probiotics sustain youthful testosterone levels in aging mice. Another study2 revealed that probiotics reduces cortisol levels. The implications here are equally relevant. Cortisol, as you may know, is a stress hormone and a major testosterone killer. For a more in-depth look, visit our post on the relationship between probiotics and testosterone.

    Probiotics Increase Sex Drive

    Are you not performing up to par in the bedroom? Like testosterone, one may not equate probiotics with libido, but studies3 reveal a link between inflammatory bowel disease and sexual dysfunction.

    The main function of probiotics is to improve gut health and eliminate bloating and gas by promoting better digestion. This affects other areas of your health, including your libido. How so?

    Recently, scientists have begun referring to the gut as the second brain. Much like the brain between our ears, the gut contains millions of neurons that affect our emotional response. The network of nerves within the gut is known as the enteric nervous system. This system is believed to be the part that regulates the emotional response, which in turn regulates sexual urges.

    A study published in the Columbia Alumni Association revealed that the probiotic found in yogurt not only enhanced libido but also increased testosterone and reduced risk of autoimmune disease.

    Probiotics Reduce Risk of Prostate Cancer

    According to the American Cancer Society, one in nine men will be diagnosed with prostate cancer in his lifetime. This is another area where probiotics may prove to be extremely beneficial for men.

    Research suggests probiotics may treat benign prostatic hyperplasia (BPH), or what’s more commonly referred to as an enlarged prostate. BPH also has a strong correlation with urinary tract infections.

    The American Prostatitis Association recommends the probiotic strains Lactobacillus and Bifidobacterium. Both have strong lactic acid properties that enable them to survive the stomach’s high acidic environment.

    Best Probiotics for Men

    The strains we list are just as beneficial for women and children. However, these are especially good for the guys due to their ability to reverse ailments that especially affect men. These strains, by the way, are all found in our own probiotic supplement Floracil50.

    Lactobacillus Rhamnosus

    L. rhamnosus is a top probiotic for men due to its ability to improve sperm motility and potentially induce weight loss, according to studies4. Another study5 revealed that this probiotic may be effective as a pain reliever. This makes it a great option for muscle heads who hit the gym hard and feel the aftereffects of the grind.

    Lactobacillus Reuteri

    We can’t mention the best probiotics for men without bringing up the L. reuteri strain. In the aforementioned testosterone study with the aging mice, researchers administered the L. reuteri probiotic. Other research6 shows this strain may also combat hair loss and preserve hair follicles.

    This probiotic is so helpful that we dedicated an entire post to the benefits of L. reuteri.

    Lactobacillus Acidophilus

    The acidophilus probiotic is one of the more extensively studied strains. This is a common strain found in Women’s probiotics due to its ability to prevent vaginal infections. However, guys can benefit just as much. Evidence7 suggests the acidophilus probiotic may lower LDL cholesterol levels. This is a biggie because men over the age of 45 are the biggest demographic at risk for high cholesterol. Studies8 also show promise in this probiotic’s role in the treatment of prostate cancer.

    Bifidobacterium Infantis

    Despite its name, this probiotic is just as good for adults as it is for infants. This is another one of the good probiotics for men due to its ability to treat kidney stones. According to the National Kidney Foundation, the condition is more prevalent in men than women. While researchers are still not entirely clear why, they suspect it’s because men tend to consume more protein and salt. Studies9 show that the B. infantis strain may nullify the effects of urinary stones.

    Probiotics for Men Are an Overall Health Enhancer

    The health benefits of probiotics go far beyond what it does for your gut. When you have better digestion, all other parts of your health naturally follow. The gut, after all, is the center of the body and interconnected to all other areas, from the brain to the immune system. It’s not hard to see why probiotics play such a pivotal role in men’s health. Probiotics are the precursor for male hormones.
