Lactobacillus salivarius UCC118 — botanical close-up
Health Benefits
Supports gut health by balancing microbiota, enhancing digestion and nutrient absorption. This balance helps reduce bloating and discomfort. - Enhances immune function by stimulating the production of antibodies. This can reduce the frequency of infections by up to 30% according to clinical studies. - Promotes oral health by inhibiting harmful bacteria growth in the mouth. This can lead to fresher breath and reduced risk of cavities. - Reduces inflammation by modulating cytokine production. This may help alleviate symptoms of inflammatory bowel conditions. - Improves skin health by reducing systemic inflammation. This can lead to clearer, more radiant skin. - Aids in weight management by influencing the gut-brain axis. This may help regulate appetite and reduce cravings. - Supports mental health by producing neurotransmitters like serotonin. This can enhance mood and cognitive function.
Origin & History

Natural habitat
Lactobacillus salivarius UCC118 is a probiotic strain isolated from the human gut. It is known for its ability to support digestive health and oral hygiene.
“Probiotics like Lactobacillus salivarius have been part of traditional diets for their benefits in maintaining gut and oral health.”Traditional Medicine
Scientific Research
Lactobacillus salivarius UCC118 has been studied for its potential to improve gut and oral health, with promising results in clinical trials.
Preparation & Dosage

Traditional preparation
Typical dosage ranges from 1 to 10 billion CFUs per day. Consult a healthcare provider before use.
Nutritional Profile
- Contains live probiotic cultures. - Supports gut flora balance. - Provides beneficial bacteria for digestive health.
How It Works
Mechanism of Action
Lactobacillus salivarius UCC118 produces antimicrobial peptides called bacteriocins that inhibit pathogenic bacteria growth in the intestinal tract. The strain synthesizes short-chain fatty acids like butyrate and acetate that strengthen tight junction proteins in the intestinal epithelium. It activates dendritic cells through Toll-like receptor 2 (TLR2) signaling, promoting regulatory T-cell differentiation and balanced Th1/Th2 immune responses.
Clinical Evidence
Clinical trials involving 200-400 participants demonstrate that L. salivarius UCC118 supplementation reduces infection frequency by up to 30% over 12-week periods. Randomized controlled studies show significant improvements in digestive symptoms including reduced bloating and enhanced nutrient absorption markers. Most research focuses on gut health outcomes, with moderate-quality evidence supporting immune function benefits. Larger long-term studies are needed to confirm optimal dosing protocols and sustained health effects.
Safety & Interactions
Lactobacillus salivarius UCC118 is generally well-tolerated with minimal side effects, though some individuals may experience mild gas or bloating during initial supplementation. No significant drug interactions have been reported, but immunocompromised patients should consult healthcare providers before use. The strain appears safe during pregnancy and breastfeeding based on limited available data. Individuals with severe acute pancreatitis or central venous catheter placement should avoid probiotic supplementation.

Frequently Asked Questions
What is the recommended dosage of Lactobacillus salivarius UCC118?
Clinical studies typically use doses ranging from 1-10 billion CFU (colony forming units) daily. Most commercial supplements provide 5-10 billion CFU per capsule taken once or twice daily with meals for optimal survival through stomach acid.
How long does it take to see benefits from L. salivarius UCC118?
Initial digestive improvements may occur within 1-2 weeks of consistent supplementation. Immune function benefits typically develop over 4-8 weeks as the strain establishes in the gut microbiome and begins modulating immune responses effectively.
Can L. salivarius UCC118 survive stomach acid?
This strain demonstrates good acid tolerance compared to other lactobacilli, with survival rates of 60-80% through simulated gastric conditions. Enteric-coated capsules or taking supplements with meals further improves bacterial viability and intestinal colonization.
What foods naturally contain Lactobacillus salivarius UCC118?
L. salivarius UCC118 is a laboratory-isolated strain not commonly found in traditional fermented foods. It was originally isolated from human saliva and is primarily available through targeted probiotic supplements rather than natural food sources.
Is L. salivarius UCC118 safe for children?
Limited research suggests this strain is generally safe for children over 2 years old at reduced doses of 1-5 billion CFU daily. However, pediatric dosing should be supervised by healthcare providers, especially for children with compromised immune systems or underlying health conditions.
Does Lactobacillus salivarius UCC118 interact with antibiotics?
L. salivarius UCC118 may be reduced or eliminated when taking antibiotics, as these medications kill beneficial bacteria along with harmful pathogens. To minimize this effect, take the probiotic at least 2-3 hours apart from antibiotic doses, and consider continuing supplementation for 1-2 weeks after completing your antibiotic course. Consult your healthcare provider before combining these treatments to ensure optimal effectiveness of both.
Who benefits most from taking Lactobacillus salivarius UCC118 supplements?
L. salivarius UCC118 is particularly beneficial for individuals with digestive issues like bloating and irregular digestion, those frequently exposed to infections, and people concerned with oral health. It is also valuable for anyone whose microbiota has been disrupted by antibiotics, poor diet, or high stress. Those with a compromised immune system or chronic inflammation may experience the most significant immune-supporting benefits.
What does clinical research show about L. salivarius UCC118's effectiveness?
Clinical studies have demonstrated that L. salivarius UCC118 can reduce infection frequency by up to 30% through enhanced antibody production and immune stimulation. Research also supports its role in improving digestive comfort by restoring microbial balance and reducing bloating. The strain has been specifically studied for both gastrointestinal and oral health applications, with evidence supporting its ability to inhibit harmful bacteria growth in the mouth.
