Lactobacillus Casei is one of the best documented and most studied probiotics with an excellent ability to tolerate the acidic environment of the human gastrointestinal tract.
Probiotic supplements with Lactobacillus casei have extensive benefits, providing a viable microorganism which supports and promotes a healthy balance of the microbes living in our gut.
This health enhancing bacteria is sometimes used in the production of cheddar cheese and in some yogurts. It can also be found in fermented dairy and plant products like fermented green olives.
In addition to aiding overall digestive and immune system health, it has been reported to lower cholesterol, inhibit growth of unhealthy bacteria in the intestinal tract, help reduce symptoms of lactose intolerance, control diarrhea, enhance immune responses and to decrease risk for bladder cancer.
Lactobacillus casei has been proven to adhere to the mucosa in the human intestine and to colonize the gastrointestinal tract.

Friendly bacteria are vital to a healthy and properly functioning microbiome. Our immune system relies on the healthy bacteria in our gastrointestinal tract to support its development and assure appropriate responses to pathogens, inflammation and infection.
Lactobacillus Casei is a member of the LABs (Lactic Acid Bacteria). It works in particular with another probiotic called lactobacillus acidophilus which functions by converting carbohydrates into acids and hydrogen peroxide.
This creates an acidic environment which is unfavorable to the growth of pathogenic, or unhealthy, bacteria.
L. acidophilus relies on support from lactobacillus casei and other beneficent bacteria to aid in its production of lactic acid. Studies show that this combination decreases antibiotic related diarrhea and clostridium difficile (diarrhea causing) infections in adults.
Clinical trials also demonstrate that it works to reduce recovery times for children suffering with rotavirus.
Many unhealthy, or bad, bacteria cannot grow or thrive in the gut if the pH balance isn’t conducive to its growth.
The creation of an acidic environment is important to keep this balance in check, as well as the healthy reproduction of non-pathogenic bacteria like lactobacillus casei, which occupy space which otherwise could be taken up by bad bacteria.
Benefits of Lactobacillus Casei Supplementation
Besides generating better overall digestive health, L. casei supplements can give your immune system a much needed boost.
While doing so, many people experience relief from chronic constipation or diarrhea due to imbalances occurring within the GI tract. This is, in large part, due to the proper balancing of the entire gastrointestinal microbiome.
Individuals report improvement with conditions such as Crohn’s disease, Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD).
Pancreatic necrosis, which is an acute and sudden inflammation of the pancreas, can in many cases prove fatal. Researchers found that treatments which include lactobacillus casei help to inhibit the migration of pathogenic bacteria from the pancreatic area to other locations in the body where they can cause additional problems or infections.
How Much Lactobacillus Casei to Take
Some yogurts, cheeses and fermented food products contain lactobacillus casei, though it can be nearly impossible to know exactly how much is contained in any given serving, or how viable the bacteria in the food remains over time.
Supplements offer a standard dosage which have been shown to improve the balance of microflora in the human gut. It is important to select a product manufactured and sold by a reputable company to be certain your supplement contains both the correct dosage, the correct bacteria and that the desired bacteria are alive and thriving.
For establishing balance in the gut flora, or for use in restoring gut flora following antibiotic use, lactobacillus casei sources can be taken alone, or in combination with lactobacillus acidophilus for optimal benefits.
Purchase lactobacillus casei in freeze dried powder form, in capsules or in tablets. This bacteria is sensitive to heat, moisture and oxygen. Keep supplements in a dry place at room temperature and away from direct light.
Personalized dosage recommendations should come from your personal medical provider, but a general recommendation is five-million live bacteria taken twice each day.
Side Effects of Lactobacillus Casei
L. casei has been shown to be generally safe to use but it is recommended, as with all supplements, that you seek the advice your physician before commencing treatment.
Particularly, if treating specific symptoms or illness, a holistic medical doctor’s advice can be quite valuable both for monitoring progress and for any contraindications with other medications you may be taking.
Review
Lactobacillus casei has been shown to be a safe and effective probiotic. It can be taken in conjunction with other probiotics to enhance their effectiveness. It has been shown to be particularly effective when taken in combination with L. acidophilus.
Many GI tract symptoms have been reported to be helped or healed with supplementation of lactobacillus casei, including IBS, diarrhea, constipation, IBD, Crohn’s disease. In addition, it can provide a general boost to overall immune function.
Important considerations when purchasing this product are assurance of the correct strain of bacteria and viability of the live cultures.

Yet another positive benefit has been elucidated – the ability to remove bis-Phenol A (BPA) from the body. From the first link below:
“Specific probiotics, Bifidobacterium breve and Lactobacillus casei are two beneicial bacterial strains that bind BPA and eliminate it from the intestines.”
