How to Choose a Good Men’s Probiotic

Because so many dietary supplement manufacturers exist, choosing the best probiotic brand for your needs can feel challenging. With a simple Google search, you’ll find hundreds of options, ranging from the New Chapter Probiotic and HUM Gut Instinct Probiotic to the Garden of Life Raw Probiotics for men. To narrow your options and find the best probiotics, we recommend you begin with our list above, then consider the factors below.

High CFUs Per Serving

Colony-forming units (CFUs) define how many viable microbial cells are in the probiotic supplements. The more viable cells, the more beneficial results you can experience, though you don’t want to consume formulas with extreme potency beyond the standard safety level. While certain individuals with specific conditions may experience beneficial results from CFUs in the 200 billion range or even trillions, most average men do not require this.

The International Scientific Association for Probiotics and Prebiotics requires intestinal health supplements to have at least 1 billion CFUs to meet probiotic qualifications. The options on our list range from 10 to 100 billion CFUs. Most clinical research suggests that the minimum effective dosages range from 10 to 20 billion CFUs.

If you’re new to probiotic supplements, you may want to start with the smaller dosage and work your way up. If you’ve tried probiotics for men in the past without great results, consider trying an option with 50 to 100 billion CFUs.

Bacteria Strain Diversity

Each bacterium interacts with your body in different ways. While CFU count may be important, you also want diverse probiotic supplements that include multiple types of bacteria for the most comprehensive results. Many of the best probiotics for men on our list offer over 10 powerful strains, allowing you to enjoy the most benefits.

Avoid Fillers

Sometimes probiotics may contain fillers, like artificial preservatives, colors, or sweeteners. Such harmful ingredients can cause adverse reactions and negative side effects, preventing you from enjoying all the wonderful benefits that probiotic supplements should offer. The best probiotics for men on our list include all-natural formulas without fillers, harsh chemicals, dyes, or preservatives.

We also recommend considering common allergens like gluten, soy, and dairy when reviewing the label. Such ingredients can cause gastric distress if you have an allergy, so be sure to select gluten-free, dairy-free, and soy-free probiotics if you’re concerned.

Save Money with Bulk-Buy Discounts

Probiotic supplements are typically more expensive than most other vitamins and minerals because of the live cultures and complex absorption methods. Most of the best probiotics for men on our list cost around $30 to $60 per month, though you can score discounts by purchasing in bulk.

After selecting your preferred probiotic supplements, we recommend subscribing and saving for discounted costs. You may also receive additional perks like free shipping or gifts.

Men’s Health Benefits of Taking a Daily Probiotic

The best probiotics for men offer head-to-toe benefits that can transform how you feel daily. While the primary results may occur in your digestive system, this improvement offers rebounding effects throughout your entire body.

Typically, you must take probiotic supplements for at least a few weeks or months to begin experiencing such results. The top benefits you can expect with the best probiotics for men include the following.

Improved Digestive Health

Your digestive system breaks down all the food you eat so your body can absorb vital nutrients like carbohydrates, proteins, fats, fibers, and more. Poor digestion inhibits this process and results in various uncomfortable symptoms and conditions like bloating, gas, diarrhea, constipation, IBS, nausea, heartburn, acid reflux, and more.

People often suffer from digestive issues due to imbalanced gut bacteria. When you lose helpful bacteria in your gut microbiome, your entire body may suffer the consequences. Many people experience reduced cognitive function, increased stress and anxiety, poor sleep, skin breakouts, improper blood sugar regulation, chronic disease risks, and more.

Probiotic supplements can help replenish your gut’s helpful bacteria, improving how your digestive system functions and alleviating the symptoms above. Taking the best probiotics for men can allow you to enjoy reduced stomach discomfort and easier digestion.

Immune System Support

The immune system includes a vast network of cells, tissues, and organs that help your body fight infections, illnesses, and diseases. If your immune system doesn’t function properly, you may get sick more often or for longer periods as your body struggles to recover. Research shows that probiotics can regulate host immune responses, which is critical in terminating infections during the primary carrying state.

The best probiotics for men may both prevent and treat various diseases by balancing defense mechanisms during innate and adaptive immune responses. With this immune system support, you can reduce your chances of contracting things like the common cold or flu.

Additional Benefits

By balancing the gut microbiome and improving immune responses, the best probiotics for men also offer the following benefits:

Sharpened focus and cognitive function: By improving the gut-brain axis, probiotics can help strengthen focus, cognitive function, and mental endurance.

Boosted prostate health: Probiotics can boost testosterone levels, improving prostate health with better sperm concentration levels, volume, and motility.

Strengthened cardiovascular health: Specific probiotics can reduce cholesterol and high blood pressure levels, improving cardiovascular health.

Respiratory health support: Probiotics may protect your airway against respiratory pathogens and reduce allergy-related inflammation, offering impr oved respiratory health.

Improved skin health: Certain probiotics, like L. paracasei, can strengthen your skin’s barrier and improve its health and overall appearance.

Better metabolic health: Your metabolism converts food into energy. A faster and healthier metabolism burns through more calories, offering potential weight loss results. By aiding in nutrient absorption, probiotics can improve glucose metabolism speeds.

Weight loss support:Probiotics may help with and target weight loss by improving digestion, reducing bloating, regulating bowel movements, increasing satiety (with prebiotics), and stimulating fat loss.

Regulated bowel movements: Probiotics can regulate bowel movements in patients suffering from various conditions that cause diarrhea, constipation, or other irregularities.

Improved oral health: Your oral cavity requires a balance of helpful and pathogenic bacteria like your digestive system. Probiotics can replenish the essential bacteria in charge of critical oral health functions.

Frequently Asked Questions about Probiotic Supplements

Finding the best probiotics for men can feel overwhelming, so we understand that you likely have a few questions. Thoroughly researching any dietary supplement before purchasing it is an excellent way to develop expectations and understand how it may interact with your body. Explore answers to the most frequently asked probiotics questions below so that you can confidently select a supplement.

Should Men Take Probiotics?

Most men are likely to benefit from probiotics, considering the wide range of effects and ample clinical research surrounding their results. If unsure whether or not you should take probiotics, we recommend speaking with a health care professional.

While probiotics can help relieve various symptoms, they cannot cure severe diseases or conditions. If you have preexisting conditions or take prescription medications, we recommend consulting your doctor about whether probiotics may help you.

Can Men’s Probiotics Help with Weight Loss?

Men’s probiotics can help contribute to weight loss in a few ways, though they won’t directly cause it.

We recommend selecting probiotics with prebiotic fibers, as they can increase satiety, helping you stick to your diet. Probiotics can help you cut bloating and water weight, which may initially reduce the scale's number. With regular bowel movements, you may also see fat loss improvements.

You should follow a healthy diet and exercise routine to lose weight while taking probiotics.

What’s the Difference Between Probiotics and Prebiotics?

Probiotics are live bacteria, while prebiotics are dietary fibers that the bacteria feed on. You can take probiotics and prebiotics independently, though they work best when used together.

Prebiotics increase your fiber intake, which can regulate bowel movements, increase satiety, and reduce cravings. Taking prebiotics with your probiotics can improve the supplement’s effectiveness, offering a more nourishing environment for the bacteria to thrive in. Unless you regularly consume a decent amount of fiber in your daily diet, consider a probiotic that includes prebiotic fibers.

Do Probiotics for Men Have Any Side Effects?

The best probiotics for men typically have little to no side effects because they only include all-natural and organic ingredients that won’t harm your body. People occasionally report minor gastric distress when beginning the probiotic regimen as their body adjusts to the influx of helpful bacteria. Any initial side effects should wear off quickly, so if you experience prolonged effects, you should contact your doctor.

Typically, people only experience more severe reactions to probiotics when they include unsafe fillers, harsh chemicals, or common allergens. Be sure to review the ingredient list on the supplements you choose if you have any food allergies.

Do Probiotic Supplements Have to Be Refrigerated?

Not all probiotic supplements require refrigeration, though it depends on the brand, strains, and packaging. Common strains have extreme heat sensitivities and may require refrigeration to stay alive before entering your digestive system.

Some options on our list feature various protective qualities that remove the refrigeration requirement. Read the supplement’s packaging and follow all storage instructions for optimal results.

What Fermented Foods Contain Good Probiotics?

Aside from taking probiotic supplements, you can also consume helpful bacteria in your diet. Many fermented foods contain impressive levels of good probiotics that can offer beneficial results, especially when combined with supplements. A few foods containing probiotics include the following:

• Yogurt
• Kefir
• Sauerkraut
• Kombucha
• Pickles
• Tempeh
• Miso
• Sourdough bread
• Kimchi
• Natto
• Certain soft cheeses or curds
• Dhokla

If you regularly eat any of the above items in large portions, you may want to consider a lower-dose probiotic. You can research the average CFUs in the items above, though certain yogurts and other products advertise it on the label. We recommend considering this when calculating your daily dosage.

Final Thoughts on Men’s Probiotics

The best probiotics for men offer clinically-proven whole-body benefits, ranging from digestive and immune function support to improved skin and prostate health and many benefits in between. We reviewed all the top manufacturers and compiled a list of the best probiotics for men based on the claimed benefits, CFU counts, strain varieties, and key features.
