What are the side effects of Lactobacillus rhamnosus GG?

Potential side effects include: Mild bloating and gas (usually transient), Rare: bacteremia in severely immunocompromised patients, Generally very well tolerated.

What is Lactobacillus rhamnosus GG and how does it support immunity?

Lactobacillus rhamnosus GG (LGG) is one of the most extensively studied probiotic strains. Research suggests it may strengthen gut barrier function, stimulate secretory IgA production, and reduce the incidence and duration of respiratory and gastrointestinal infections.

What dosage of Lactobacillus rhamnosus GG has been used in studies?

Clinical trials have used LGG at doses of 1 billion to 10 billion CFU per day, with most pediatric studies using 1–5 billion CFU and adult studies using 5–10 billion CFU. Supplementation periods typically range from 4 weeks to 6 months.

What are the potential side effects of Lactobacillus rhamnosus GG?

LGG is generally recognized as safe for most populations, including children. Mild bloating or gas may occur initially. Caution is advised for severely immunocompromised individuals or those with central venous catheters, where rare cases of bacteremia have been reported.

About

LGG is one of the most extensively studied probiotic strains worldwide. It enhances intestinal barrier integrity and stimulates gut-associated lymphoid tissue (GALT), promotes IgA secretion, and modulates systemic immune responses by balancing pro- and anti-inflammatory cytokines. Systematic reviews show reduced incidence and duration of upper respiratory infections.

How It Works

Enhances intestinal barrier integrity and stimulates GALT; promotes IgA secretion; modulates systemic immune responses by balancing pro- and anti-inflammatory cytokines; competitively excludes pathogens from intestinal epithelium.
