The Benefits of Lactobacillus Rhamnosus

A good time in the bedroom starts by taking care of your gut and rectal microbiomes — and Lactobacillus rhamnosus can help you get there. You might not consider this superhero bacteria to be part of your anal game, but it can work wonders for your digestion, gut, and tush.

Whether you’ve just started bottoming or consider yourself a power bottom, it’s never too late to start prioritizing your anus by improving your gut health. Keep reading to learn more about this miracle probiotic and its numerous health benefits.

What Are Lactobacillus Rhamnosus Probiotics?

L.rhamnosus is a bacteria that naturally resides in your gut. Sometimes referred to as Lactobacillus rhamnosus GG (LGG), it’s one of the most well-studied probiotics on the market. Found in probiotic supplements and milk, yogurts, and other dairy products, this probiotic has hundreds of different strains each with unique abilities. LGG is also resistant to acid and bile and can influence adaptive immune responses in the body.

What are the Health Benefits of Lactobacillus Rhamnosus?

A vast number of bacteria resides in your gut — roughly 50 trillion — if we’re counting. Diarrhea, IBS, and other digestive issues occur when the bad bacteria outnumber the good bacteria, which is why incorporating probiotics into your diet is essential. 

L.rhamnosus has numerous health benefits that can help combat bad bacteria so your digestive and immune health can thrive.

1. Promotes a healthy gut

A healthy gut is a happy one, and bile acids are key players in gut health. They play an essential role in regulating the gut microbiome. Low bile acid levels have been associated with bacterial overgrowth and inflammation, but certain strains of LGG can promote healthy bile salts, which can lower cholesterol levels and liver triglyceride levels.

2. Provides relief to IBS symptoms

IBS — or irritable bowel syndrome — is a chronic condition that can cause bloating, gas, diarrhea, and other digestive problems. 

While its cause is unknown, IBS can be triggered by imbalances in the gut microbiome. Probiotics like L.rhamnosus can restore gut flora.  

A recent review of 104 clinical studies that evaluated the use of probiotics to treat IBS symptoms found that L.rhamnosus had the highest efficacy on quality of life, bloating, and abdominal pain.

3. Can help prevent diarrhea

Diarrhea is an unpleasant experience for anyone and can be caused by several different factors, such as bacterial infections and digestive issues. 

While diarrhea can disrupt the microbes in your gut, probiotics like L.rhamnosus can help restore your good bacteria. 

L.rhamnosus has been shown to help regulate dendritic cells (the immune cells that fight against antigens) and prevent diarrhea caused by Rotavirus, which is a severe form of watery diarrhea prevalent in children. 

Another study published in the American Academy of Family Physicians found that a high dosage of L.rhamnosus could moderately reduce the duration of antibiotic-induced diarrhea by nearly one day, once more demonstrating the powerful effects of this probiotic.

4. UTI prevention

Most urinary tract infections (UTIs) are caused by bacteria. Those assigned female at birth are more likely to contract a UTI, as the urethra is close to their vagina and anus, which makes it easier for E. coli bacteria to enter the urethra. 

Simply wiping back to front or engaging in sexual activity can increase the risk of a UTI. One scientific review found that L.rhamnosus was the most effective at preventing UTIs by restoring urogenital flora. This and other probiotics may be especially beneficial for women suffering from recurrent UTIs. 

5. Stronger teeth

Another amazing benefit of L.rhamnosus that’s been studied is its ability to fight the harmful bacteria that reside in your mouth. Dealing with cavities is never fun and it may seem like no matter how many times you brush your teeth per day, you may not be reaching every spot.

One study found that using L.rhamnosus laced lozenges twice a day resulted in improved gingival health and a decrease in harmful bacteria that leads to tooth decay.

6. Sexual benefits

L.rhamnosus has numerous benefits when it comes to sexual health. The use of antibiotics, vaginal douching, pregnancy, and other factors can harm vaginal health, but studies show that L.rhamnosus treats bacterial vaginosis and other common conditions. 

Anal douching, penetration, and lube can all disrupt the balance of the bacteria in your rectum, sending it out of wack. L.rhamnosus probiotics can pave the way to better anal sex by restoring the rectal microbiome.

Dr. Goldstein says, "A lot of people don’t really think of the gut component, but when I communicate to people in my private practice, Bespoke Surgical, I’m always trying to say, ‘Stop thinking locally. Let’s start thinking about the entire body and gut health, from appropriate diet, use of fiber supplementation, the addition of pre- and probiotics, exercise. This translates to better anal health, and, ultimately, better sexual health overall."

Other health benefits

If the previous scientific-backed examples don’t impress you, L.rhamnosus has a flurry of other benefits that are continuing to be studied, including: 

  • Reducing the occurrence of gestational diabetes
  • Encouraging weight loss
  • Enhancing sensitivity to insulin
  • Lowering blood cholesterol levels 
  • Relieving allergy symptoms
  • Treating acne 
  • Healing ulcers

Why Are Lactobacillus Rhamnosus Probiotics So Beneficial?

L.rhamnosus probiotics are beneficial for anal, gut, and respiratory health and continue to be studied to treat a wide array of conditions. One study found that L.rhamnosus improved outcomes in cystic fibrosis patients, reducing pulmonary exacerbations and increasing weight gain.
