Lactobacillus rhamnosus GG

Lactobacillus rhamnosus GG (LGG) is a highly clinically researched probiotic strain of bacterium that naturally inhabits the human digestive tract. It is exceptionally resilient against stomach acid and bile, allowing it to colonize the gut successfully. It works by competing with pathogenic bacteria for adhesion sites, producing short-chain fatty acids, and enhancing the gut barrier and mucosal immune response.

Dosage by Body Weight

The standard dose ranges from 5 billion to 20 billion CFUs daily, depending on age and clinical indication. For children, powder from sachets or drops is preferred. Avoid mixing the probiotic with hot foods or liquids as heat destroys the live bacteria. If prescribed alongside antibiotics, administer the probiotic at least 2 hours apart.
