Table of Contents

What are the health benefits of Lactobacillus Paracasei?

The health benefits of Lactobacillus Paracasei include the following:

  1. Boosting the immune system
  2. Preventing inflammation
  3. Improving digestion
  4. Reducing allergies
  5. Promote healthy skin
  6. Improves liver function
  7. Decreasing obesity by stimulating the fat metabolism
  8. Improve dental health
  9. Inhibits infections
  10. Helps with insulin resistance
  11. Has antimicrobial properties

A study published in the Journal of Clinical and Developmental Immunology in 2011, discussed the effect of lactobacillus paracasei on the immunity of lab mice by preventing inflammation. Similarly, a recent study published in the Journal of Foods in 2021, revealed the health-promoting properties of lactobacillus paracasei in preventing infections.

What’s the role of Lactobacillus Paracasei Lpc-37?

Lactobacillus Paracasei Lpc-37 can help in relieving chronic stress and reducing anxiety levels. A study published in the Journal of Neurobiology of Stress in 2020, revealed that lactobacillus paracasei Lpc-37 reduced stress. However, they recommended that these claims should be further confirmed.

Other benefits of Lactobacillus Paracasei Lpc-37 include the following:

  • Promotes relaxation of the mind
  • Improves mental health and well-being
  • Regulates stress
  • Manages feelings of anxiety

What are the benefits of Lactobacillus Paracasei Casei 431?

The benefits of Lactobacillus Paracasei Casei 431 include the following:

  • Decreasing infection duration
  • Promotes digestion health
  • Acts as an immunomodulatory

In fact, a study in 2012, showed that supplementation with Lactobacillus Paracasei 431 stimulated immune response. However, another study in 2015, didn’t impact the immune response to influenza vaccination but it did reduce the duration of infection.

Similarly, a recent study in 2022, investigated the short and long-term effects of lactobacillus paracasei 431 on energy, and hormone levels in humans. They found out that it didn’t have a significant impact on these parameters and the researchers recommended further studies be conducted.

What is Lactobacillus Paracasei?

Lactobacillus Paracasei is a type of lactic acid bacteria that can be found naturally in the mouth or intestinal flora of humans as well as in fermented dairy products and vegetables. It’s most commonly used in the fermentation process and has various health benefits.

A study in the Journal of Clinical Oral Investigations in 2011, demonstrated the inhibitory effect lactobacillus paracasei had on Streptococcus mutans (a type of bacteria present in the moth that causes dental caries). 

In the video below, Dr. Ryan Bentley explains how Lactobacillus Paracasei is a great probiotic to help support your overall health and your immune function:

Recommended Probiotic Supplement with Lactobacillus Acidophilus:

Is Lactobacillus Paracasei effective for treating Histamine intolerance?

Lactobacillus Paracasei is effective for treating histamine intolerance where it metabolizes built-up histamine in the body and restores the normal balance. Evidently, a study in the Journal of Immunity, Inflammation, and Disease in 2016, revealed that lactobacillus paracasei was beneficial in treating allergies as compared to other probiotic strains.

Another recent study in 2020, identified Lactobacillus paracasei as being both safe and effective in degrading histamine.

Can Lactobacillus Paracasei be used for managing Rosacea?

Lactobacillus Paracasei can be used for managing rosacea by balancing the levels of good bacteria in the gut with bad bacteria. It also has an anti-inflammatory property which helps in alleviating inflammatory symptoms associated with Rosacea.

A study in 2017, recommended implementing a diet with lactobacillus paracasei to promote a healthy gut and reduce symptoms of rosacea. Moreover, a recent study in 2022, showed the positive effect of topical probiotics on certain skin conditions like rosacea.

Why is the Lactobacillus Paracasei St11 Supplement good for the Skin?

 The Lactobacillus Paracasei St11 supplement is good for the skin as it provides the following functions:

  • Reducing skin sensitivity
  • Maintaining skin moisture
  • Recovery of barrier functions
  • Anti-inflammatory functions

A study published in the Journal of Beneficial Microbes in 2017, revealed that supplementation with Lactobacillus Paracasei St11 for 56 days had a very good impact on eliminating dandruff with no reported side effects.

What are the benefits of Lactobacillus Paracasei D3-5?

The benefits of Lactobacillus Paracasei D3-5 include the following:

  • Regulates the dysbiosis of the gut microbiome
  • Modulates mucus production
  • Promotes metabolism
  • Enhances cognition
  • Improves mental health
  • Reduces inflammation associated with age
  • Benefits musculoskeletal function

To that end, a study published in the Journal of GeroScience in 2020, reiterated the health benefits of Lactobacillus Paracasei D3-5 in preventing age-related inflammation and leaky gut.
