In a healthy state there is a huge diversity of microorganisms in our body. There are similarities between some microorganisms but they have subtle, and often significant, differences in how they help with various aspects of our health. As a general rule of thumb, Lactobacilli tend to live in the small intestine and their properties include the secretion of digestive enzymes to help break down food, whereas Bifidobacteria tend to live in the large intestine and amongst other benefits, are important to ensure we have regular bowel movements. However, within each of these genus of bacteria there are many species, and within each species there are many strains; these strains have been shown to have different effects on the body.
For example, in comparing the properties of two different strains from the same species: L. rhamnosus, it soon becomes apparent that they have totally different attributes. L. rhamnosus Rosell-11 has been shown in numerous clinical trials to stabilise gut health when taking antibiotics, and to reduce the risk of associated digestive symptoms1. L.rhamnosus GR-1® on the other hand has not been shown to directly aid digestive health; instead it has been shown to colonise in the vaginal tract2 and to help maintain balance in the microflora of the intimate area, especially in common intimate health conditions3, 4 ,5.
Lactobacillus rhamnosus GR-1® is one of the strains in Optibac Probiotics For Women.
Health professionals can view both strains of L.rhamnosus on the Probiotics Database: L. rhamnosus Rosell-11 L. rhamnosus GR-1®
When it comes to probiotics, research shows us time and time again, that it is certainly not a case of ‘one-size-fits-all’.
