Breaking Down the Different Types of Probiotics and Their Unique Benefits
Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. They are
often referred to as “good” or “friendly” bacteria because they help keep your gut healthy by maintaining a
balanced microbial environment. Probiotics can be found in certain foods, beverages, and dietary supplements.
Let’s break down the different types of probiotics and explore their unique benefits.
1. Lactobacillus
Lactobacillus is a common type of probiotic that is naturally found in our digestive system. It is also present
in some fermented foods like yogurt and sauerkraut. Lactobacillus helps in the breakdown of lactose, making it
highly beneficial for individuals who are lactose intolerant. It also supports the immune system and helps
prevent harmful bacteria from taking over the gut.
2. Bifidobacterium
Bifidobacterium is another type of probiotic that is commonly found in the intestines. It helps with digestion
and nutrient absorption, particularly in breaking down carbohydrates. Bifidobacterium also promotes regular
bowel movements and supports a healthy immune system. This probiotic is often found in dairy products, such as
cheese and milk.
3. Saccharomyces boulardii
Saccharomyces boulardii is a yeast probiotic that offers unique benefits. Unlike other probiotics, it is not
bacteria but a type of fungus. This probiotic is highly effective in preventing and treating diarrhea, including
antibiotic-associated diarrhea and traveler’s diarrhea. Saccharomyces boulardii also helps restore the natural
balance of microorganisms in the gut after disruptions caused by medications or illnesses.
4. Streptococcus thermophilus
Streptococcus thermophilus is a probiotic commonly used in the production of yogurt and cheese. It is known for
its ability to support the digestion of lactose and increase the bioavailability of certain minerals, such as
calcium. This probiotic also enhances the body’s natural defense mechanisms and contributes to overall gut
health.
5. Lactococcus lactis
Lactococcus lactis is a beneficial probiotic commonly found in fermented dairy products. It aids in the
fermentation process and helps produce lactic acid, which contributes to the tangy flavor of fermented foods.
Lactococcus lactis also helps maintain a healthy gut environment by inhibiting the growth of harmful bacteria
and supporting immune function.
6. Bacillus subtilis
Bacillus subtilis is a spore-forming probiotic commonly found in soil and the gastrointestinal tracts of
animals. It is known for its ability to survive harsh conditions, such as stomach acid, making it highly
effective for oral supplementation. Bacillus subtilis supports digestive health, strengthens the immune system,
and promotes a healthy balance of gut bacteria.
7. Escherichia coli Nissle 1917
Escherichia coli (E. coli) Nissle 1917 is a probiotic strain that has been extensively researched for its various
health benefits. It is known for its ability to support the gut barrier function and modulate the immune
response. E. coli Nissle 1917 has been used to alleviate symptoms of inflammatory bowel diseases, such as
ulcerative colitis. It is important to note that this strain is different from the pathogenic E. coli strains
that can cause illness.
8. Bacteroidetes
Bacteroidetes is a phylum of bacteria that includes several probiotic strains. These bacteria play a crucial role
in maintaining a healthy gut microbiota and are associated with benefits like weight management and a reduced
risk of metabolic disorders. Bacteroidetes probiotics, such as Bacteroides fragilis, contribute to the
production of short-chain fatty acids, which provide nourishment to the cells lining the colon and help regulate
inflammation.
