Probiotics Benefits For Men – From Heart Health To ED!


Probiotics have risen in popularity in recent years as research uncovers their potential to benefit digestive health and beyond. But could probiotics also offer specific advantages for men? Let’s explore the science behind probiotics and their effects on men’s health issues like heart disease, weight management, urinary tract infections (UTIs), and more.

Do Probiotics Offer Specific Advantages for Men’s Health?

Probiotics are beneficial strains of live bacteria and yeasts that provide health benefits when consumed. They help repopulate your gut microbiome or the community of microorganisms living in your intestines.

Probiotics for men

A balanced microbiome aids digestion, nutrient absorption, immunity, and more. Probiotics may also favorably impact conditions affecting men’s well-being, such as:

  • Cardiovascular disease 
  • Obesity and weight loss
  • Colon and prostate cancer risk
  • Urinary tract infections
  • Erectile dysfunction
  • Anxiety and depression

Research on probiotics is still emerging and many studies show small or inconclusive effects so far. However certain probiotic strains show promise in improving biomarkers and symptoms related to these men’s health issues. Let’s analyze the evidence surrounding probiotics and men’s wellness.

Probiotics For Heart Health

Heart disease is the leading cause of death for men in the US. Can probiotics improve cardiovascular risk factors in men? Here’s what studies suggest:

Probiotics may modestly lower LDL “bad” cholesterol and triglycerides while raising HDL “good” cholesterol. Effects vary based on probiotic strain.

Fermented dairy products containing probiotics slightly reduce blood pressure, a cardiovascular risk factor.

  • Probiotics help reduce inflammation involved in atherosclerosis through effects on inflammatory compounds like CRP.
  • Probiotics decrease platelet aggregation, which reduces the risk of dangerous blood clots that could lead to heart attack or stroke.

While more research is needed, probiotics show the potential to optimize several heart health biomarkers in men. However, they should complement, not replace, a healthy lifestyle and any medications prescribed by your doctor.

Probiotics For Weight Management

With obesity on the rise, researchers are interested in how probiotics may affect weight: 

  • Certain probiotic strains appear to modestly reduce body weight, body mass index (BMI), and fat percentage according to some studies.
  • Probiotics may influence appetite signals and hormones involved in fat storage like insulin and leptin.
  • Effects likely relate to the interaction between gut microbes and weight regulation. However, the results remain preliminary.

Probiotics may offer a complementary strategy alongside diet and exercise to maintain a moderate weight. But they are not a cure for obesity on their own.

Probiotics against Colon and Prostate Cancer

Some small studies have linked specific strains of probiotic supplements or fermented milk products to potential anti-cancer benefits:

  • Probiotics may bind to potential carcinogens and promote their excretion from the colon, reducing colorectal cancer risk.
  • Fermented dairy products with probiotics reduced biomarkers of tumor growth and progression in rodent studies of prostate cancer.
  • Benefits are likely mediated through probiotic effects on immunity, inflammation, and antioxidant activity.
  • Much more research is required to determine clinical efficacy for cancer prevention.

While probiotic supplements do not replace cancer screenings or standard care, optimizing your gut microbiome may someday prove a beneficial complementary strategy for men at average risk of developing certain cancers.

Probiotics Against Urinary Tract Infections

Urinary tract infections (UTIs) primarily affect women but also occur in men. Probiotics could help by:

  • Acidifying the pH in the urethra and bladder which impedes bacterial colonization.
  • Blocking pathogenic bacterial adhesion and subsequent infection.  
  • Enhancing antimicrobial activity of bladder cells against invasive bacteria.

These mechanisms indicate the potential for probiotics to reduce the risk of recurrent UTIs in susceptible men. Certain strains like Lactobacillus rhamnosus GR-1 appear most promising for UTI prevention based on preliminary research.

Probiotics for Erectile Dysfunction 

Small studies have linked probiotics to improved erectile function and sexual health in men: 

  • One study found men who consumed probiotic supplements for 4 weeks experienced decreased inflammation and oxidative stress throughout the body, including the penis. These changes were associated with firmer, longer-lasting erections.
  • Another study reported probiotic yogurt consumption for 12 weeks improved sexual quality of life scores in diabetic men struggling with erectile dysfunction.
  • Experts think reduced inflammation and insulin resistance may lead to better erectile function.

More research is needed to confirm the effects, but probiotics may someday offer a natural complementary remedy for erectile dysfunction.

Probiotics For Mental Health

Your gut microbiome communicates directly with your brain through what’s known as the gut-brain axis. Early studies suggest probiotics may benefit mental health issues like anxiety, depression, and stress:

  • Probiotics reduced symptoms of anxiety, perceived stress, neuroticism, anger, hostility, and self-blame in several small human studies.
  • Benefits are thought to result from effects on vagus nerve signaling, production of mood-regulating neurotransmitters, and reduced inflammation.
  • Exact strains and dosages remain unclear and larger trials are needed.

Nonetheless, this provides exciting preliminary evidence that optimizing your gut microbiome with probiotics could support mental well-being and mood in men.

Choosing An Effective Probiotic 

If you’re looking to try probiotics, be sure to:

🔹Talk with your doctor first, especially if you have any medical conditions

🔹 Select reputable brands that list strain names like Lactobacillus or Bifidobacterium

🔹 Choose products listing CFUs (colony-forming units) in the billions 

🔹 Look for strains with benefits specific to your health needs

🔹 Start low and go slow with dosage to assess tolerance

🔹 Use for at least 4 weeks to notice a difference

🔹 Refrigerate probiotic supplements to maintain viability

Pair probiotics with prebiotics like fiber that feed beneficial gut bacteria. Adopting a gut-friendly diet, managing stress, exercising, and getting enough sleep also supports microbiome balance.

Are There Any Risks With Probiotics?

For most healthy people, probiotic supplements are very safe with minimal risk. However, you should exercise some caution if you have: 

➜ A weakened immune system or serious illness

➜ A critical condition like heart valve disease 

➜ The potential for infections like a central venous catheter

Rare cases of infection, sepsis, and other complications have occurred in extremely vulnerable people taking probiotics. Otherwise, side effects are generally mild like bloating and gas. Monitor how you feel and discontinue probiotics if any concerning symptoms develop.

As with any supplement, check with your physician before starting a regular probiotic regimen, especially if you have underlying health conditions or take medications that could interact.

Frequently Asked Questions 

1. Can probiotics help with ED or impotence?

Early research indicates probiotics may potentially improve erectile function and sexual performance in men by lowering inflammation and insulin resistance. Larger studies are still needed.

2. Do probiotics really help you lose weight?

Certain strains appear to have modest effects on reducing body weight, BMI, and fat percentage according to some preliminary studies. Probiotics likely complement a healthy diet and active lifestyle more than independently causing significant weight loss.

3. What is the best probiotic for gut health?

Strains from the Lactobacillus and Bifidobacterium genera tend to be most effective for overall gut health. Look for broad spectrum blends that contain well-studied strains like Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium bifidum.

4. Can I take probiotics forever safely? 

For most healthy individuals, probiotic supplements are very safe for long term, regular use. They may be taken indefinitely to maintain a favorable gut microbiome. But consult your doctor first, especially if you have any health conditions or take regular medications.

5. How long does it take for probiotics to start working?

Research suggests taking probiotics consistently for 2-4 weeks provides time to sufficiently establish the beneficial bacteria in your gut before you’re likely to notice digestive or other health improvements. Effects continue to build with sustained use.


Early research reveals encouraging potential for probiotics to benefit several aspects of men’s health, though large-scale, definitive clinical trials are still needed. Specific probiotic strains show promise for enhancing heart health, aiding weight management, reducing cancer risk factors, preventing recurrent UTIs, improving erectile function, and supporting mental wellbeing in men.

Probiotics likely act through mechanisms involved in gut microbiome balance, inflammation modulation, and reducing insulin resistance. Consult your doctor to see if adding probiotic-rich foods or supplements makes sense as part of your personalized wellness plan.
