Hours of cardio and strength training may help your gut look good on the outside, but it’s what’s on the inside that matters—in this case, your gut health. The gut has been called “the second brain” and people have been trusting it for generations, but we guys often do more to hurt it than help it (I’m talking about a guy’s night at the bar—you know who you are.)

No worries, though—our choices for the best probiotic for men are formulated to benefit men’s gut health and reduce symptoms like bloating, constipation, and nausea, and even boost your athletic performance. You might be weirded out by the fact that probiotics contain live bacteria (several billion of them, in fact), but we’ll tell you why that’s nothing to worry about and how it can actually help you.

Our 9 Top Picks for the Best Probiotic for Men 

Best Overall Probiotic for Men: Ritual Synbiotic+

Good for: Those who want to increase the effectiveness of their probiotic


Ritual Synbiotic+

GGR Score: 4 starstarstarstarstar

Product Highlights

  • Filled with prebiotics, probiotics, and postbiotics
  • Clinically studied 
  • Supports gut barrier function
  • Delayed-release capsule designed so bacteria reaches the colon

Pros & Cons


  • Traceable ingredients
  • Supports gut lining and gut barrier function
  • Vegan
  • Non-GMO
  • Delayed-release capsule


  • Expensive
  • Automatically signs you up for subscription
  • There can be uncomfortable side effects at first

Bottom Line

The Ritual Synbiotic+ is a clinically backed probiotic with clean, traceable ingredients designed to support overall digestive health.

Ritual Synbiotic+ is “cutting edge and a winner,” says supplement expert and registered dietitian Bob Iafelice. He points to the 11 billion colony-forming units (CFU) of the two most-studied strains of good bacteria, BB-12 and LGG, delayed-release capsule to bypass stomach acid, and additions of prebiotics and postbiotics as his reasoning for recommending this as the best probiotic supplement for men.

The BB-12 and LLG strains have been linked to improved gastrointestinal and immune health, and Iafelice says the 11 billion CFU dose is large enough to be effective.

The registered dietitian was also impressed with the inclusion of tributyrin, a postbiotic. The International Scientific Association of Probiotics and Prebiotics (ISAPP)20 defines postbiotics as the byproduct of postbiotics feeding off of prebiotics. One example of a postbiotic is butyrate, a short-chain fatty acid that a January 2018 review21 reported could help with immunity and ease inflammation, though the researchers specified more research needed to be done. 

Tributyrin is a more effective form of butyrate, according to Iafelice. “It’s great for maintaining the integrity of the gut lining,” he says. “Of course, this is critical for protecting against autoimmune conditions.”

ritual pill in hand synbiotic

The natural question is, “Do I need postbiotics in my probiotic?” Ritual would like you to think so, and even did two studies on its supplement’s effectiveness, so maybe you shouldn’t be surprised that they found it had great gut health benefits. 

As a rule, we’re weary of studies done or paid for by supplement companies since they may have a hand in designing the study, which increases the chance of them making it so the study reaches their predetermined conclusion (to be clear, we’re not accusing Ritual of this, but it has been done by some companies). 

RELATED: Best organic protein powder

That said, independent research as recent as April 202222 have said postbiotics should be explored and may have significant benefits but that more research needs to be done. 

Dosing instructions 1 capsule per day with or without food

Best Synbiotic Probiotic for Men: Biotics 8

Good for: Men who want to improve their overall gut health

Best Overall

Bauer Nutrition Biotics 8 Probiotic

GGR Score: 4 starstarstarstarstar

Product Highlights

  • Men’s-specific probiotic for gut health
  • Made to help strengthen your immune system
  • Built in digestive enzymes
  • Claimed to support gut health, mood, digestion, and immunity
  • 3 capsules per day

Pros & Cons


  • Made to be taken long-term
  • In capsule form, so you don’t get the bad taste that some powders possess
  • Also contains vitamin D as well as the probiotic blend
  • Can save money by purchasing in bulk
  • No refrigeration required


  • Expensive for the amount of capsules
  • Limited reviews of the product
  • Not vegan- or vegetarian-friendly
  • Supposed to take 3 capsules a day, which is a lot

Bottom Line

These capsules contain 10 strains of probiotics with a guarantee of 20 billion CFUs per serving (per three capsules).

Biotics 8 is a one-stop shop for men’s gut health needs. Like many of our top picks, it comes packed with probiotics (the live bacteria) and prebiotics, which are essentially food for probiotics to help them do their job, according to this 2019 review1. The combination of these two creates a synbiotic probiotic, which researchers say has promising benefits. 22

It also contains several digestive enzymes to aid with your digestive system, and according to a February 2016 review2, may enhance probiotics effectiveness in treating gastrointestinal diseases (though the researchers clarified more studies need to be done on those claims). 

We like Biotics 8 for men because it’s specifically formulated for men. One example of this is the addition of vitamin D, which when combined with probiotics could reduce men’s overall disease risk and improve several health markers such as insulin sensitivity, according to a January 2021 meta-analysis3.

Vitamin D4 and probiotics5 have also both been linked to increased testosterone levels in men, though Bauer Nutrition specifies it takes about a month of continuous use to notice this benefit. 

Speaking of continuous use, Biotics 8 requires you to take three capsules per day to get the most out of its probiotics, which is about the average amount of other probiotics. It’s best to take these all at once first thing in the morning.   

Another benefit of Biotics 8 is they specify it doesn’t have to be refrigerated, so you can take them on the go. Refrigerating probiotics tends to make them last longer, as heat can kill the organisms inside, but that doesn’t seem to be a problem here. 

Dosing instructions 2 capsules/day (16 billion CFUs)
Strain(s)Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus fermentum, Bifidobacterium longum, Bifidobacterium bifidum, Bifidobacterium breve, Saccharomyces Boulardii
Storage No refrigeration required 
Cost$2.00/serving in 30-serving container 

Best Probiotic for Athletic Men: Kaged Pro-Biotic 

Good for: Athletes or men who live a very active lifestyle 

For Athletes

Kaged Muscle Pro-Biotic

GGR Score: 3.5 starstarstarstarstar

Product Highlights

  • Patented probiotic strain
  • Targets gut muscles to enhance training
  • Human trials show reduced fatigue
  • Target-release capsules bypass the stomach to release in intestines

Pros & Cons


  • Could help athletic performance
  • Third party tested clean formula
  • Backed by science
  • Promotes gut health
  • Save money by subscribing


  • Pricey per serving
  • Must be taken 3 times a day for full effects

Bottom Line

Kaged Muscle Pro-Biotic is great for those looking to add to their workout supplements as it not only promotes gut health but also could improve athletic performance.

A November 2022 clinical review6 found that athletes could improve their performance and even reduce recovery time with probiotic supplementation. Kaged Pro-Biotic contains TWK10®, a patented version of the probiotic strain known as L. plantarum, that’s made specifically for athletes who want to see such benefits. 

A November 20197 study found TWK10®, which is naturally fermented from kimchi, had significant impacts on exercise performance, body composition, muscle energy, and endurance. Some test subjects also experienced “significant” fat loss, though they were given a high dose of TWK10®. 

RELATED: Best pre-workout for men

It has also been linked to better immune health and decreased fatigue, both of which are very important to those living an active lifestyle.    

Kaged gets major bonus points for only requiring one capsule per serving. The company ensures each serving will be effective by making its capsules with hypromellose—a May 20058 study found this compound allows the organisms inside the capsule to remain untouched until it reaches the intestines for full absorption.  

This is important because if the capsule dissolves in the stomach the probiotic bacteria may not be fully absorbed and you may not experience the positive side effects you were looking for. 

Dosing instructions 1 capsule with breakfast, lunch, and dinner (10 billion CFUs/capsule)
Strain(s)L. plantarum (as TWK10™)
Storage Not indicated 
Cost$0.23/capsule for a 90-capsule container 

Best Probiotic for Men for Immunity: Transparent Labs Probiotic-Advanced Gut Health Formula 

Good for: Any man who’s trying to support his immune system or reduce his overall disease risk

Immune Health

Transparent Labs Probiotic-Advanced Gut Health

GGR Score: 3 starstarstarstarstar

Product Highlights

  • Made with 10 different probiotic strains
  • Can be bought on a subscription basis
  • Has 100 billion CFUs per serving
  • 2 capsules is 1 serving

Pros & Cons


  • Made to promote a healthy gut and strengthened immune system
  • No artificial sweeteners, coloring, or preservatives
  • Has more than 1,000 five-star reviews


  • Not many product reviews
  • Transparent Labs recommends that the capsules be taken on an empty stomach

Bottom Line

The Transparent Labs Gut Health Series Probiotic is aimed to aid in immune support, overall gut health, and more.

There are 100 billion alive and active microorganisms present in each serving of Transparent Labs Probiotic-Advanced Gut Health Formula, which is easily the highest amount we’ve seen in the best probiotic supplements. There are 10 different strains of probiotics, each with a differing amount of colony forming units (better known as CFUs). 

The most prevalent strain is Lactobacillus acidophilus (25 billion CFU), which a November 2020 study9 found was beneficial in treating chronic diarrhea, an indicator of poor digestive health. Lactobacillus rhamnosus, the second-most prevalent strain (15 billion CFU), has been found to be effective in treating gastrointestinal infections, irritable bowel syndrome (IBS), inflammatory bowel disease, and more, according to this March 2019 review10.

transparent labs gut health

You get the point—it’s chock full of a whole lot of live gut bacteria that have major benefits for your gut and immune health. What’s more, it’s free of artificial sweeteners, artificial colorings, and preservatives, all of which could cause bloating and negatively impact your immune system. 

Each serving is only two pills and they’re quite easy to swallow. We like that the capsules are made with hypromellose to ensure a delayed-release delivery until they reach the intestines8.  

Dosing instructions 2 capsules/day with a full glass of water, preferably on an empty stomach, or as directed by a healthcare professional
Strain(s)Lactobacillus acidophilus (LA-14), Lactobacillus rhamnosus (LR-32), Lactobacillus casei (LC-11), Lactobacillus plantarum (LLP-115), Lactobacillus paracasei (LPC-37), Bifidobacterium lactis (BL-04), Lactobacillus salivarius (LS-33), Streptococcus thermophilus (ST-21), Bifidobacterium bifidum (BB-02), Bifidobacterium breve (BB-03)
Storage Not indicated
Cost$45.99/30 servings = $1.53/serving

Best Dairy-Free Probiotic for Men: Probiology Gut+

Good for: Men with dairy sensitivities 


Probiology Gut+

GGR Score: 4 starstarstarstarstar

Product Highlights

  • A live strain probiotic and prebiotic supplement pill
  • Claims to improve your mood, body, and skin
  • Rated 3.8 out of 5 stars
  • From Ark Labs 
  • A dietary supplement for better gut health
  • Contains 40 billion CFU

Pros & Cons


  • A boost of energy and focus
  • Improves digestion
  • Claims to relieves stress
  • Formulated to prevent bloating
  • Aims to strengthen your immune system
  • Made with vegan and non-GMO ingredients


  • Not FDA-approved
  • It can be expensive when taking the recommended amount
  • Reviews have reported stomach aches, diarrhea, and nausea after a few days of use

Bottom Line

Probiotic supplements like Probiology Gut+ claim to help your body fight off bacteria naturally and create intestinal balance for a more comfortable gut. For some, this product reportedly works well, with users noting improvements in their gut health, mood, and energy and stress levels. However, it’s important to listen to your body and consult your doctor with any questions that may arise before or during use.

Although probiotic supplements may not clearly state they contain dairy, people with lactose intolerance or other dairy sensitivities should be aware that some probiotic strains are made from dairy and could do more harm than good. Probiology Gut+ contains no such strains, so it’s safe for anyone living a dairy-free lifestyle. 

This probiotic contains 40 billion CFUs from four different strains, but it uses a proprietary blend so it’s unclear whether each strain contains enough CFUs to be effective at their jobs. Among the four strains is Lactobacillus acidophilus, associated with a reduced risk of diarrhea and better immune health9, and bifidobacterium lactis, which a June 2016 study14 linked with increased nutrient absorption and improved bowel movements.  

The company boasts the inclusion of brown seaweed extract, which they claim helps the probiotic withstand stomach acid “250 times better” than standard probiotics. A 2010 overview15 of the compound seems to back up this claim, but a more recent review published in February 202016 states there’s much more research that needs to be done on these claims.  

Dosing instructions One capsule in morning and one at night with water, or as directed by healthcare professional
Strain(s)Lactobacillus acidophilus, Bifidobacterium lactis, Lactobacillus plantarum, Lactobacillus paracasei
Storage No refrigeration needed 
Cost$39.95/30 servings = $1.33 per serving 

Best Allergen-Friendly Probiotic for Men: Vitamin Shoppe Ultimate 10+ Probiotic

Good for: Anyone who wants to ensure their probiotic is free of allergens

No Allergies

The Vitamin Shoppe Ultimate 10+ Probiotics

GGR Score: 3.5 starstarstarstarstar

Product Highlights

  • The Vitamin Shoppe authorized Ultimate 10+ Probiotics 
  • Supports immune, digestive,and respiratory health
  • Options for 13–100 billion CFUs
  • It does not contain GMOs, gluten, dairy, or soy
  • Comparably affordable
  • Contains prebiotic fiber for healthy gut flora

Pros & Cons


  • Variety in product and amount of CFUs
  • A once daily supplement
  • 12 probiotic strains for happy gut health
  • Verified purity and potency from a third-party company
  • Free of GMO, gluten, soy, tree nuts, egg, wheat, shellfish, peanuts, and fish
  • Improved stomach pain for many reviewers
  • It does not require refrigeration
  • Claims to promotes respiratory health


  • Not FDA-approved
  • Some reviewers experienced unwanted side effects like cramping, nausea, bloating, diarrhea, and constipation

Bottom Line

As a top 200-rated product for Prebiotic Nutritional Supplements on Amazon, Ultimate 10+ Probiotics works well for many people. It’s essential to be aware of any potential side effects and risks. However, The Vitamin Shoppe is a well-known and trusted brand for this kind of supplement.

Like we mentioned above, probiotics themselves don’t have dairy, gluten, or other common allergens, but the strains used in them might have been extracted from food items known to cause problems in some people. 

Vitamin Shoppe Ultimate 10+ Probiotic comes in differing strengths—13, 20, or 30 billion CFUs—and is gluten-free, dairy-free, soy-free, and non-GMO. It’s also our choice for the best budget probiotic for men, since a 100-serving bottle only comes out to $22.99, or $0.22 per capsule, (for the 13 billion CFU option). 

As with most budget-friendly dietary supplements, Vitamin Shoppe Ultimate 10+ Probiotic comes with some artificial ingredients that are mostly used to increase the supplement’s shelf life. While it does have 12 different bacterial strains, it’s a proprietary blend so we’re unsure how much of each is present.

On the bright side, there are some major players here: Lactobacillus acidophilus to treat chronic diarrhea9, Lactobacillus rhamnosus to fight off gastrointestinal diseases10, and bifidobacterium lactis for improved nutrient absorption and bowel movements14

Dosing instructions One capsule per day, with or without food
Strain(s)Lactobacillus Rhamnosus, L. Casei, L. Acidophilus, L. Plantarum, Bifidobacterium Lactis, L. Bulgaricus, L. Salivarius, B. Bifidum, Streptococcus Thermophilus, B. Longum, B. Breve, L. Gasseri
Storage Store in cool, dry place 
Cost$22.99/100 servings = $0.22 per serving*

Best Raw Probiotic for Men: Garden of Life Raw Probiotics Men

Good for: Any man who wants an organic probiotic

It’s Raw!

Garden of Life Raw Probiotics Men

GGR Score: 3.5 starstarstarstarstar

Product Highlights

  • Raw probiotics for men
  • Includes 31 probiotic strains
  • Promotes a healthy immune system
  • Contains 85 billion CFUs in each capsule
  • Supports digestion, stress, heart, and prostate health
  • Garden of Life is Carbonfree Certified

Pros & Cons


  • Climate Pledge Friendly on Amazon and Carbonfree Certified
  • Includes digestive enzymes
  • No gluten, soy, or allergens
  • Contains no carriers, fillers, artificial colors, or preservatives
  • Contents can be poured from the capsule into juice or water to drink


  • Must be refrigerated
  • Manufactured in a facility that also processes soy, peanuts, tree nuts and shellfish
  • Not FDA-approved

Bottom Line

Garden of Life empowers you to feel in control of your well-being with an optimal bacterial balance in your digestive system. Reviewers have even mentioned gaining a boost in energy while taking the supplements.

The bacteria found in some probiotics is sometimes treated with heat, which can decrease the positive side effects of those strains (this is done to reduce some potential negative side effects of ingesting live bacteria). Garden of Life uses a “raw” probiotic, which is when bacterial strains are extracted from whole foods instead of using isolated strains. 

There are limited scientific studies on raw probiotics, but a small August 2012 study17 found promising results when it came to improvements in gut health. 

garden of life probiotics

Garden of Life uses a mixture of Bulgarian yogurt, which was featured in a February 2021 review18 for the unique bacteria found in it and their potential benefits on human gut health, Eastern European kefir (a fermented milk drink that has active cultures), and scobies (the bacteria that works alongside yeast to ferment drinks like kombucha). 

It also contains an original probiotic strain called Lactobacillus fermentum, which researchers in April 2011 reported 19 was linked to an improved immune system in athletes and active male adults. While most probiotic strains are fine for men and women, the researchers emphasized that not enough is known on how this specific strain can affect a woman’s immune system and that more research is needed.

Best Vegan Probiotic for Men: Omni-Biotic AB 10

Good for: Men who live a plant-based lifestyle 

Plant Based

Omni Biotic AB 10

GGR Score: 4 starstarstarstarstar

Product Highlights

  • Clinically tested restorative probiotic
  • Includes 5 billion CFUs
  • Supports and restores gut flora
  • Digestive probiotic for diarrhea and constipation
  • Vegan, hypoallergenic, and non-GMO
  • It comes with a 30-day supply of powder packets
  • Drinkable supplement in vanilla flavor

Pros & Cons


  • 83% of good bacteria reach the gut through the freeze-dried and powder-delivery mechanism
  • Provides gut restoration and antibiotic support
  • No refrigeration needed
  • Drinkable supplement for those who do not enjoy taking pills


  • Relatively expensive
  • Not FDA-approved
  • Some reviewers did not enjoy the taste
  • Powder packets must be dissolved in water to ingest

Bottom Line

As a convenient, effective, and supportive probiotic supplement, the Omni Biotic AB 10 is an excellent option. If you enjoy taking supplements through drink form and not having to refrigerate the product, then this may be a good option for you. One main downside is the slightly higher price compared to other probiotics on the market.

While there are few studies on the effectiveness of vegan probiotics—which, as a reminder, are probiotics that are derived from plant-based food sources rather than dairy or other animal-based products—a wide-ranging review on vegans’ gut health published in April 201923 found they had a more diverse group of beneficial bacteria than meat eaters. 

Omni-Biotic AB 10 seeks to foster that kind of bacterial diversity with its probiotic blend containing 5 billion CFUs of multiple strains. Because it’s a blend, we’re not sure how much of each is present in a serving, but we do spot some strains that we like to see in a probiotic supplement: Lactobacillus acidophilus for diarrhea10, Lactobacillus rhamnosus for gastrointestinal health11, and bifidobacterium lactis for improved nutrient absorption15

One downside of Omni-Biotic is its price, with each serving coming out to $2.26. That’s on the higher end of our list, but I’ve been noticing some benefits from continuous use of this probiotic supplement and the customer reviews are nothing but complimentary, so you may find it worth the price. 

It’s also the only one on our list that’s a powder instead of a pill—you simply rip open the sachet and pour it into a glass of water (they tell you to leave it for a minute), stir, and then drink.  

RELATED: Best vegan protein powder

Dosing instructions Open one sachet and pour into a glass of water. Allow to sit for 1 minute, stir, and drink. 
Storage Store in cool, dry place at room temperature 
Cost$68.00/30 servings = $2.26 per serving 

Best Soil-Based Probiotic for Men: Ancient Nutrition SBO Probiotics Ultimate 

Good for: Men who are interested in soil-based supplements

From the Dirt

Ancient Nutrition SBO Probiotics

Product Highlights

  • Great for digestion, gut flora, and immune system support
  • Contains 50 billion CFUs
  • Rated 4.6 out of 5 stars on Amazon
  • Gluten-free product
  • Sold on Amazon for easy shipping and delivery
  • Does NOT need to be refrigerated
  • Made by Dr. Josh Axe of the Keto Diet

Pros & Cons


  • No refrigeration necessary
  • No dairy, gluten, soy, or artificial sweeteners
  • Meets the quality standards through third-party Current Good Manufacturing Practices
  • Positive reviews
  • Claims to improve bloating, stomach pain, IBS symptoms, constipation, and reflux


  • Not FDA-approved
  • Mixed reviews about how easy the supplement pill is to swallow
  • No returns on the purchase
  • Some reviews mentioned their product was open or broken when it arrived.

Bottom Line

By including clinically studied probiotic ingredients that have been shown to reduce constipation, diarrhea, and bloating, the SBO probiotic supplement may be a good probiotic choice for you.

Soil-based probiotics are exactly what they sound like—probiotics that contain bacterial strains extracted from the soil. Ancient Nutrition SBO Probiotics Ultimate contains four soil-based probiotic strains, along with prebiotics (the bacteria’s food)1 and postbiotics for improved immunity and inflammation response20.

RELATED: Best-tasting protein powder

If you’re wondering whether soil-based probiotics is just a marketing term or legit, consider that researchers in August 201924 said, “[Soil] was essential in the evolution of the human gut microbiome.” That said, studies as recent as July 202025 have said there’s still much to learn about how soil-based probiotics can be used to benefit human health, though early results are promising. 

Ancient Nutrition’s soil-based probiotics contains four strains: Saccharomyces boulardii, Bacillus clausii, Bacillus coagulans, and Bacillus subtilis. Saccharomyces boulardii is a yeast and the only of the four that’s not a soil-based bacterial strain, though researchers in July 202126 said it could help with gut health and possibly even slow down cognitive decline.  

This probiotic is free of most food allergies and is made with a hypromellose capsule to ensure the strains are not affected by your stomach acid and survive the trip to the intestines10

Dosing instructions 2 capsules per day with water 
Strain(s)Saccharomyces boulardii, Bacillus clausii, Bacillus coagulans, and Bacillus subtilis
Storage No refrigeration needed 
Cost$52.89/30 servings = $1.76 per serving 

How We Picked and Tested the Best Probiotic for Men

With so many probiotics on the market, some of which claim to be the absolute best supplement for men, it was a little challenging to narrow our top picks down to just 10 choices. Here’s the criteria we used to finalize our list:

  • Colony forming units: It should be noted that a high number of colony forming units, or CFUs, doesn’t mean a supplement is a high-quality probiotic, but we wanted to ensure our choices had at least 1 billion—which is generally the minimum amount recommended by researchers. This number refers to the number of good bacteria in a probiotic. 
  • Storage and expiration information: Bacteria are living organisms so their shelf life is limited compared to creatine, protein shakes, or protein powder. Some may need to be refrigerated to prevent the bacteria from dying, which would make the supplement less effective. 
  • Bacterial strains: Not only did we look for a diversity of strains, but we wanted to ensure that each supplement had research-backed bacteria that are proven to provide benefits to those who take them. 
  • Price: How much did each supplement cost and what was the price per serving?  
  • Ingredients: Does the probiotic supplement contain other ingredients? Do they serve a purpose or could they potentially be harmful?
  • Certifications: We looked for certifications showing that the probiotic supplement were third-party tested or had other certifications such as Vegan, Kosher, Halal, and Gluten-Free.

RELATED: Best protein bars

Benefits of Probiotics 

A 2018 meta-analysis27 concluded that healthy adults could improve their gut health and lead to a better immune system and bowel movements. 

There are additional benefits for men specifically. Studies have shown that consistent probiotic use could lead to increased testosterone counts or slow down age-related testosterone decreases5 and improve prostate health.  

It should be noted that many probiotic strains can be found in fermented foods like kimchi and sauerkraut.

Buying Guide: What to Look for in Probiotic for Men

Here’s what you should look for in a probiotic for men: 

  • Colony forming units: How many living organisms are present in the supplement? There should be at least 1 billion, but remember that more isn’t necessarily better. 
  • Storage and expiration information: If your probiotic needs to be refrigerated make sure to do so. 
  • Bacterial strains: Ask your physician which strains are best suited for your overall health needs. 
  • Price: Find a probiotic that fits your budget.

FAQs About Best Probiotic for Men 

Are probiotics good for males?

Probiotics are good for males and females, as research has consistently linked the supplements to improved gut health and immunity. For men, it could also lead to improved testosterone levels or slowing down the age-related decrease of the vital hormone.

What is the best probiotic for men’s health?

Here are our top 10 picks for the best probiotics for men: 

Best Overall Probiotic for Men: Biotics 8

Can men take probiotics daily?

There’s no danger in taking a daily probiotic, but you should always consult a doctor or nutrition expert before starting a new supplement regimen.

Do probiotics affect testosterone?

Yes, but in a good way. Research has shown that continuous probiotic use can increase testosterone levels or reverse the age-related decline of the hormone. It’s important to note that this comes from continuous use and that you won’t see any such benefits by just taking it once or twice.
