L. paracasei, even if heat-killed, inhibits S. mutans and decreases caries lesions in rats (R).
5) L. paracasei is Beneficial for the GI Tract
L. paracasei Improves Intestinal Microflora
L. paracasei further increases acetic acid and butyric acid, while it decreases ammonia (R).
L. paracasei Strengthens the Intestinal Barrier
L. paracasei modulates intestinal digestion, absorption of nutrients, energy metabolism, lipid synthesis and intestinal protective functions in mice (R).
Fermented milk with L. paracasei promotes intestinal epithelial cell growth and intestinal epithelial integrity to strengthen the intestinal barrier against chemical and inflammatory stimuli-induced damage (R).
L. paracasei therapy prevents antibiotic induced visceral hypersensitivity and restores normal gut permeability in rats (R).
L. paracasei is Beneficial in Diverticular Disease
L. paracasei, in association with a high-fibre diet, is effective in reducing abdominal bloating and prolonged abdominal pain in patients with symptomatic uncomplicated diverticular disease (R).
L. paracasei Ameliorates Diarrhea
L. paracasei Relieves Constipation
L. paracasei Ameliorates GI Inflamamation
L. paracasei prevents intestinal inflammation in mice with colitis (R).
Oral supplementation of L. paracasei reduced the clinical progression of necrotizing enterocolitis in infants (R).
L. paracasei May Alleviate IBS
L. paracasei supplementation prevents bowel symptom onset in patients on long-term proton pump inhibitors (R).
6) L. paracasei May Improve Liver Function
L. paracasei lowers liver fat deposition and serum ALT level in mice with nonalcoholic steatohepatitis (NASH) (R).
L. paracasei reduces total blood and liver cholesterol in rats and decrease liver damage due to alcohol intake (R).
L. paracasei symbiotic (containing arabinogalactan, fructooligosaccharides) lessens NAFLD progression in rats, lowers inflammatory markers and reduces the severity of liver injury and insulin resistance (R).
7) L. paracasei May Ameliorate Insulin Resistance
8) L. paracasei Combats Obesity
Water extract of L. paracasei reduces body weight in obese rats. It decreases the formation of lipid plaques in the aorta, reduces fat cell size and inhibits fat absorption, thereby reducing fat production (lipogenesis) (R).
L. paracasei decreased body fat in mice (R).
L. paracasei decreases triacylglycerol in human subjects (R).
L. paracasei decreases energy/food intake in both human and animal subjects (R).
9) L. paracasei is Great for the Skin
L. paracasei contributes to the reinforcement of skin barrier function, inhibits water loss, decreases skin sensitivity and modulates the skin immune system leading to the preservation of skin homeostasis (R).
L. paracasei decreases skin sensitivity and increases barrier function recovery (water retention) in women (R).
L. paracasei Improves Atopic Dermatitis
Heat-killed L. paracasei improved atopic dermatitis (AD) in adult patients (R).
10) L. paracasei May Combat Toxins

L. paracasei significantly inhibits colon cancer cell proliferation (R).
- Depending on the experimental setting, L. paracasei has different effects on cytokines.
- It both elevates and suppresses pro-inflammatory cytokines TNF-α (R,R,R,R,R), decreases (R,R) or increases IL-1β (R,R), and inhibits (R) or elevates IFN-γ (R,R).
- L. paracasei mostly induces IL-12 (R,R,R,R) (in some studies decreases: R,R), and increases the proportion of NK cells (R), while reducing the Th-2 response (R,R).
- L. paracasei mostly increases IL-10 (R,R, R,R) ( a study where IL-10 is decreased: R).
- L. paracasei decreases TGF-β1(R,R), and increases TGF-β2 (R).
