Lactobacillus reuteri (L. reuteri) can affect the human body through multiple mechanisms, mainly through regulating intestinal flora, immune function support, and metabolic support pathways. The following is a detailed analysis of its effects:
1. Regulation of intestinal flora
Competitive exclusion: It outperforms harmful bacteria in terms of intestinal nutrition and adhesion sites, and can effectively exclude harmful bacteria.
Antimicrobial production: L. reuteri can secrete reuterin, a broad-spectrum antimicrobial compound that inhibits the production of pathogens.
Can strengthen the intestinal barrier: Strengthening tight junction proteins can reduce the occurrence of intestinal leakage and inflammation.
2. Immune system regulation
Enhancing regulatory T cells helps maintain immune tolerance and reduce the damage to the body caused by excessive inflammation.
Can stimulate the production of immunoglobulins: This can enhance mucosal immunity in the intestines and respiratory tract.
Reduce pro-inflammatory cytokines: Reduce TNF-α, IL-1β,6, and IL-8, which helps treat inflammatory diseases.
3. Digestive health effects
Improve bowel motility: May relieve constipation by increasing bowel movement frequency.
Reduces diarrhea: helps restore gut flora after antibiotics or infections (e.g,. rotavirus).
Supports IBS/IBD management: can relieve bloating and abdominal pain in some patients.
4. Metabolic and hormonal effects
Oxytocin stimulation: certain strains (e.g., Lactobacillus reuteri ATCC PTA 6475) can increase oxytocin levels, which is helpful for wound healing.
Effectively lowers cholesterol: it can break down bile acids and lower LDL cholesterol.
Controls blood sugar: According to research, it can also improve insulin sensitivity and blood sugar control.
5. Helps with mental health
Can effectively reduce anxiety and depression: regulates GABA and serotonin pathways through the vagus nerve.
Improves autism symptoms: Some trials have shown great benefits for the behavior of children with autism.
6. Helps with skin health
Reduces skin inflammation: helps treat acne, eczema, and dermatitis by balancing the immune response.
Protection from UV damage: Some strains may enhance antioxidant function in the skin.
Strain-Specific Effects
Not all L. reuteri strains work the same. Key strains include:
ATCC PTA 6475: Boosts oxytocin, supports skin/bone health.
DSM 17938: Reduces infant colic and diarrhea.
ATCC 55730: Improves oral health and cholesterol.
