Probiotics for Men: Which Benefits Have Evidence?

The information in this article and throughout Trio Nutrition's blog is for informational purposes only and should not replace professional medical advice. For questions about our products or orders, please contact Trio Nutrition. Written, read and reviewed by the Trio Nutrition team.

Probiotics for men are the same live microorganisms that women and other adults take. The NIH Office of Dietary Supplements defines probiotics as live microorganisms, such as bacteria and yeasts, that provide health benefits. Below, Trio Nutrition explains what the evidence shows, how strains and CFU counts work, and what men may check before choosing a supplement.*

What are probiotics, and how do they work?

Probiotics are live microorganisms that are intended to have health benefits when consumed, according to the National Center for Complementary and Integrative Health (NCCIH). NCCIH notes that probiotics may help the body maintain a healthy community of microorganisms. They may also help that community return to a healthy condition after it has been disturbed.*

The strain matters most. NIH ODS states that a product's health benefits, if any, are determined by the specific microorganisms it contains. Effects vary with the strain, how long it is used and the symptom. For an overview of the main groups, see the Trio Nutrition guide to the big 3 types of probiotics and the guide to Lactobacillus probiotics for the gut.*

What benefits do probiotics offer men?

Research on probiotics is still growing, and results differ between studies. The table below summarizes what NIH ODS and NCCIH report for adults:

NIH ODS also reports that taking probiotics might help manage symptoms of some long-term bowel conditions. NIH ODS notes that there are no official recommendations for probiotic use in healthy people, and more research on safety and effectiveness is needed. Men who deal with occasional fullness may also find the Trio Nutrition guide to everyday bloating relief useful, and those who want regularity support can read about probiotics for constipation.*

Can men take probiotics and prebiotics?

Yes. Neither the NIH Office of Dietary Supplements nor the National Center for Complementary and Integrative Health (NCCIH) gives separate probiotic guidance for men and women. NCCIH notes that probiotics have "an extensive history of apparently safe use, particularly in healthy people." NIH ODS adds that there are no official recommendations for probiotic use in healthy people. U.S. adults do use them. In the 2012 National Health Interview Survey, probiotics or prebiotics were the third most commonly used dietary supplement among adults, other than vitamins and minerals.*

Prebiotics are not the same as probiotics. NCCIH defines prebiotics as "nondigestible food components that selectively stimulate the growth or activity of desirable microorganisms." A product that combines probiotics and prebiotics is called a synbiotic. Trio Nutrition's Nirvana Kombucha is one example. Each delayed-release capsule pairs a 5 billion CFU probiotic blend with 50 mg of inulin, a prebiotic fiber from chicory root. For more, read the Trio Nutrition guide to prebiotics and gut health and the comparison of synbiotic vs probiotic supplements.*

Before choosing a probiotic, men may want to check three things:

• Strain: NIH ODS says effects depend on the strain, how long it is used, and the symptom.*
• CFU count: NIH ODS notes that a higher CFU count alone does not necessarily mean greater health benefits.*
• Safety: In healthy people, probiotics may cause gas. NCCIH notes the risk of harmful effects is greater in people with severe illnesses or weakened immune systems, so those men should talk with a healthcare provider first.*

Food or supplement: where can men get probiotics?

NIH ODS lists yogurt, cheese, sourdough bread and pickles among foods made with microorganisms. Manufacturers sometimes add probiotics to cereals, juices and milks. However, NIH ODS notes that not all these foods necessarily contain probiotics with proven health benefits. Fermented drinks are another option; see kombucha benefits for gut and daily health and kombucha for gut health.*

A supplement lists its strains and CFU count on the label, which makes intake easier to compare. Learn more in the Trio Nutrition guide to choosing a probiotic supplement for digestive health.*

How do men choose a probiotic supplement?

The label tells you most of what you need. Look for these details:

• Named strains: genus and species for each probiotic, since benefits depend on the strain (NIH ODS).*
• CFU count: stated per serving, with a note on whether it applies at manufacture or at expiration.*
• Prebiotic content: fibers such as inulin that feed desirable microorganisms (NCCIH).*
• Serving and delivery: how many capsules per day and whether the capsule is delayed-release.*
• Quality: where the product is made and whether it is lab tested.

Some men search for a "probiotic for pH balance." Read how probiotics relate to pH in the Trio Nutrition guide to probiotics for pH balance. After heavy meals, see the Trio Nutrition guide to a digestive aid for heavy meals or read about a gut cleanse. The probiotics for women and probiotics for vaginal health guides cover probiotics from a women's health angle.*

Nirvana Kombucha: a synbiotic option for men

Trio Nutrition's Nirvana Kombucha combines three ingredients in one delayed-release vegetarian capsule. Each capsule supplies organic kombucha tea extract 250 mg, inulin (chicory root prebiotic) 50 mg and a probiotic blend of 5 billion CFU (91 mg) at the time of manufacture.* The five strains are Saccharomyces boulardii, L. acidophilus, B. bifidum, B. lactis and L. plantarum. The serving is one capsule daily, with or without food, and a bottle holds 30 capsules, a 30-day supply. Nirvana Kombucha has zero sugar and no major food allergens. It is rated 4.8/5 by more than 1,200 verified buyers. It is backed by a 60-day full-refund guarantee — no return required^*. Browse more probiotics with prebiotics.

Prebiotics nourish beneficial gut microbes, probiotics provide live microorganisms with demonstrated benefits at adequate amounts, and synbiotics combine live microbes with selectively used nutrients to deliver a demonstrated health benefit. For those seeking the convenience of a combined formula, consider Trio Nutrition Nirvana Kombucha: one daily delayed-release vegetarian capsule containing 50 mg of chicory-root inulin, a probiotic blend listed at 5 billion CFU at manufacture, and 250 mg of organic kombucha tea extract. It brings these ingredients together in a simple routine, although the ingredient combination alone does not establish clinically proven synbiotic benefits.

The bottom line on probiotics for men

Probiotics for men follow the same evidence as probiotics for any adult. Benefits depend on the strain, the dose and how long it is used, and a higher CFU count is not automatically better.* Start with the label, consider fermented foods, and talk with your healthcare provider if you are seriously ill or have a weakened immune system.

Frequently asked questions

What health benefits do probiotics offer men?

The NIH Office of Dietary Supplements defines probiotics as live microorganisms, such as bacteria and yeasts, that provide health benefits. NIH ODS reports that some studies found certain probiotics shortened bouts of acute diarrhea by about 1 day, while other studies did not. Some probiotic strains might help reduce the risk of antibiotic-associated diarrhea in adults. Nirvana Kombucha provides 5 billion CFU from five strains in each delayed-release capsule.*

How long do men take to notice probiotic benefits?

The NIH Office of Dietary Supplements does not give a set timeline for probiotic effects. NIH ODS states that effects vary with the probiotic strain, how long it is used and the symptom. A healthcare provider can help set a reasonable trial period. Nirvana Kombucha provides 5 billion CFU per capsule and 30 capsules per bottle, a 30-day supply at one capsule daily.*

Do men need a different probiotic than women?

Neither NIH ODS nor NCCIH gives separate probiotic guidance for men and women. NIH ODS states that a product's benefits depend on the specific strains it contains. Nirvana Kombucha lists five: Saccharomyces boulardii, L. acidophilus, B. bifidum, B. lactis and L. plantarum. The blend provides 5 billion CFU per capsule at the time of manufacture.*

Can men take probiotics and prebiotics together?

Men can take probiotics and prebiotics together in a synbiotic, which NCCIH defines as a product that combines both. NCCIH describes prebiotics as nondigestible food components that selectively stimulate the growth or activity of desirable microorganisms. Nirvana Kombucha pairs a 5 billion CFU probiotic blend with 50 mg of inulin from chicory root. The serving is one delayed-release capsule daily.*

What side effects can probiotics cause in men?

The NIH Office of Dietary Supplements notes that in healthy people, probiotics may cause gas. NCCIH states that probiotics have an extensive history of apparently safe use, particularly in healthy people. NCCIH adds that the risk of harmful effects is greater in people with severe illnesses or compromised immune systems. Men in those groups should talk with a healthcare provider before starting a probiotic.*

What does CFU mean on a probiotic label?

CFU stands for colony-forming units, the measure used for live microorganisms in a probiotic. NIH ODS states that the number of CFUs is a more accurate representation of how many active microorganisms a product contains. NIH ODS also notes that a higher CFU count alone does not necessarily mean greater health benefits. Nirvana Kombucha lists 5 billion CFU per capsule at the time of manufacture.*
