Active Compound Heat-treated Lactobacillus LB cells and culture metabolites

Benefits

Postbiotic Mechanism

Heat-treated (non-living) Lactobacillus LB provides gut benefits without requiring viable bacteria — postbiotic category.

Supported by Trial 1

Shelf Stability

Postbiotic format enables shelf stability without refrigeration; suitable for diverse applications.

Supported by Trial 1

Immunocompromised Suitable

Non-living format eliminates probiotic bacteremia concerns — suitable for severely immunocompromised populations.

Digestive Support

Documented effects on digestive function and gut comfort.

Supported by Trial 1

Microbiome Modulation

Influences gut microbiome composition without introducing live bacteria.

Stratum Nutrition Quality

Distributed by established branded ingredient distributor.

Mechanism of action

1

Heat-Treated Bacterial Components

Heat treatment kills bacteria but preserves bacterial cell wall components, metabolites, and bioactive compounds with biological effects.

2

Immune Modulation Without Live Cells

Bacterial cell wall fragments (peptidoglycans, lipoteichoic acid) modulate immune responses without requiring live organisms.

3

Gut Microbiome Influence

Postbiotic compounds may influence existing gut microbiome composition.

Clinical trials

Clinical evaluation of Lactobacillus LB postbiotic for gut applications.

Adults with gut concerns.

Gut health and digestive benefits per studies.

Side effects and drug interactions

Common Potential side effects

Generally extremely well-tolerated.
Mild GI distress (rare).
Allergic reactions extremely rare.
Postbiotic — no live bacteria; no bacteremia risk.

Important Drug interactions

Generally minimal drug interactions.
Pregnancy — limited specific safety data; postbiotic mechanism generally safer than live probiotics.
Lactation — generally safe.
Children — appropriate at proportional doses.
Immunocompromised — postbiotic mechanism makes LBiome suitable where live probiotics may be contraindicated.
