How Much Difference Do Probiotic Supplements Make?
There are three main things that get talked about with regard to gut health:
- Prebiotics (fibrous foods)
- Probiotics (things containing live “good” bacteria)
- Postbiotics (things to help them thrive)
Today we’ll be talking about probiotics, but if you’d like a refresher on general gut health, here’s our previous main feature:

What bacteria are in probiotics?
There are many kinds, but the most common by far are Lactobacillus sp. and Bifidobacteria sp.
Taxonomical note: “sp.” just stands for “species”. The first name is the genus, which contains a plurality of (sometimes, many) species.
Lactobacillus acidophilus, also written L. acidophilus, is a common species of Lactobacillus sp. in probiotics.
Bifidobacterium bifidum, also written B. bifidum, is a common species of Bifidobacterium sp. in probiotics.
What difference do they make?
First, and perhaps counterintuitively, putting more bacteria into your gut has a settling effect on the digestion. In particular, probiotics have been found effective against symptoms of IBS and ulcerative colitis, (but not Crohn’s):

- The role of probiotics in the prevention and treatment of IBS and other related diseases: a systematic review of randomized human clinical trials
- Safety and Potential Role of Lactobacillus rhamnosus GG Administration as Monotherapy in Ulcerative Colitis Patients
- Probiotics for induction of remission in Crohn’s disease
Probiotics are also helpful against diarrhea, including that caused by infections and/or antibiotics, as well as to reduce antibiotic resistance:
- Probiotics for the prevention of Clostridium difficile-associated diarrhea in adults and children
- Probiotic approach to prevent antibiotic resistance
Probiotics also boost the immune system outside of the gut, too, for example reducing the duration of respiratory infections:
You may recallthe link between gut health and brain health, thanks in large part to the vagus nerve connecting the two:

No surprises, then, that probiotics benefit mental health. See:
- The effects of probiotics on mental health and hypothalamic-pituitary-adrenal axis: A randomized, double-blind, placebo-controlled trial
- A randomized controlled trial to test the effect of multispecies probiotics on cognitive reactivity to sad mood
- Clinical and metabolic response to probiotic administration in patients with major depressive disorder: A randomized, double-blind, placebo-controlled trial
There are so many kinds; which should I get?
Diversity is good, so more kinds is better. However, if you have specific benefits you’d like to enjoy, you may want to go stronger on particular strains:
