Bifidobacterium Longum Probiotic 200B CFU - Gut & Immune Support - Vegan, Non-GMO
Bifidobacterium longum is one of the most important probiotics in the human gut, known for its strong acid tolerance, multifunctionality, and high safety profile. It is widely present in the colon of healthy individuals, especially in the gut microbiota of infants, where it accounts for up to 90% of the bacterial population. Our product is made from Bifidobacterium breve using a high-density cultivation fermentation process and low-temperature freeze-drying protection technology. The freeze-dried bacterial powder includes the strain, protective agent, and diluent carriers.
