Final Thoughts on the Best Probiotic for Men

Best Probiotic for Men: Lactobacillus Strains

Did you know that the largest probiotic genera is called Lactobacillus biota? This genus claims more than 12 different strains of probiotics, and we’re going to go over each one below.

1. Lactobacillus Acidophilus

Best For: Improving prostate health, combating visceral fat levels, promoting digestive health, and improving muscle growth
Scientific Research Level: Heavily researched
Rating for Men: 10/10
Foods that Contain this Strain: Yoghurt, sauerkraut, probiotic supplements, and pickles

Many men worry about their prostate health, especially since 1 out of every 41 men will die of prostate cancer. Studies show that this strain of probiotics is effective at suppressing cancer cells, particularly cancer cells linked to prostate cancer in men.

Since over 1.9 billion adults are obese, the World Health Organization considers it an epidemic. Research shows that a high-fat diet can unbalance the levels of bacteria in your digestive system, and eating L. Acidophilus can help rebalance them. In turn, your digestive system will work more effectively, and this can help you lose weight.

Research has also proven that this probiotic strain can actually help your muscles absorb more nutrients. This can help them grow, and it can also help how quickly your muscles recover after a hard workout.

2. Lactobacillus Plantarum

Best For: Improving digestion, increasing immunity, and reducing the risk of kidney stones
Scientific Research Level: Heavily researched
Rating for Men: 10/10
Foods that Contain this Strain: Yoghurt, sourdough bread, olive brine, and cheese

2001 study showed that L. plantarum is effective at fighting IBS symptoms and improving your overall digestive health. During this study, 95 per cent of the participants reported a higher quality of life and a decrease in their digestive issues.

Another crossover trial showed promising results concerning L. plantarum and overall immunity levels. It helps to improve your body’s ability to absorb key vitamins and minerals, and this can boost your immune health.

Finally, L. plantarum can also reduce kidney stone risks, and this is important because men are at a higher risk for developing kidney stones than women. It breaks down the compound Oxalate, and over 75 per cent of kidney stones are classified as calcium oxalate stones.

3. Lactobacillus Rhamnosus

Best For: Improving glucose control, decreasing bacterial infections, and reducing the risk of colon cancer
Scientific Research Level: Heavily researched
Rating for Men: 10/10
Foods that Contain this Strain: Probiotic supplements, cultured cottage cheese, yoghurt, and miso

For those men who have trouble controlling their blood glucose levels, this can lead to health issues like diabetes, kidney damage, and nerve damage. Taking L. rhamnosus orally can help control your blood glucose levels.

It also has powerful antibacterial properties, and this can help to improve your overall immune health. You can find levels of L. rhamnosus in antibacterial soaps because it works topically as well as internally.

Colon cancer is one of the leading cancers that affect men more than women, and taking this probiotic has had promising results in preventing the cancer from developing in the first place. It also showed that it’s effective at calming cell inflammation.

Do you get bloated or uncomfortable after you eat or drink dairy products? If so, you may have lactose intolerance, and L. casei can help. The University of Buenos Aires ran a study that showed adding L. casei to your diet can improve your lactose tolerance.

Another study showed that L. casei can help reduce any allergy symptoms you may have. It’s effective at calming any inflammation, itchy eyes, respiratory issues, and calming your immune system’s response to your allergens.

If you have reduced liver function, you can experience several health issues, including weight loss, cirrhosis, decreased cognitive function, and an increased risk for bleeding. L. casei can help to keep your liver functioning at optimal levels and it reduces the risk of developing cirrhosis of the liver.

6. Lactobacillus Fermentum

Foods that Contain this Strain: Pickled vegetables, yoghurt, salami, probiotic supplements

Although this is one of the more widely recognized probiotic strains, in-depth research is still very young and ongoing. However, early research is promising. One study showed that L. fermentum can increase your body’s ability to absorb calcium, zinc, and phosphorous. This allows your muscles to get the most nutrients possible, and this leads to higher muscle mass.

These nutrients can increase your bone density and keep them strong as you age, improve your immune function, and improve the health of your teeth. They also help with cell division and they can help your body break down carbohydrates.

Having high cholesterol can lead to a variety of health problems including an increased risk for cardiovascular disease, increased risk for stroke, and increased risk for heart attack. Taking L. fermentum can lower your cholesterol levels and promote healthy cholesterol.
