Several studies have shown that Lacticaseibacillus rhamnosus 6594 (Probi® Rhamnosus 6594) can survive and persist in the gastrointestinal tract in humans. The strain was even recovered in the faeces in nearly all subjects up to 15 days after administration. Lacticaseibacillus rhamnosus 6594 (Probi® Rhamnosus 6594) has been shown to support the immune system, as well as improve general gut and overall health status in children as young as 11 days of age, up to adults.
