Types Of Live Cultures - Our Live Cultures Strains
Specific live cultures strains
At OptiBac we specialise entirely in live cultures, and in particular we use different strains for different groups of people and for different reasons. We aim to offer each of our customers a specific supplement to suit their individual needs. When it comes to live cultures, it is not a question of 'one-size-fits-all'!
What is a live cultures strain?
Many people (healthcare professionals included) misunderstand the definition of a 'strain'. Read on to make sure you are in the know.
The term ‘strain’ refers to a biological variety within a species; a species in turn, exists within a genus. For example, the name Lactobacillus acidophilus Rosell-52 tells you the name of the genus (Lactobacillus), the species (acidophilus), and the strain (Rosell-52). Different manufacturers use different strains, although these may be of the same species and genera; meaning that one acidophilus supplement is not equal to another acidophilus supplement. It is hence best to choose a live culture supplement that uses robust, well-researched strains.
Many of our strain names include 'Rosell' as they originated from, and have been rigorously tested by, the leading firm in the field, Institut Rosell.
For further clarification on the difference between a genus, a species and a strain, please see the relevant terms in our glossary, or read 'The Strain Myth', both of which are in the Probiotics Learning Lab.
Viable, effective strains
As well as selecting the optimum live cultures, it is important to consider the viability and efficacy of the strains themselves. The strains must be alive at the time of consumption, and must survive the stomach acidity in order to reach the intestines. The OptiBac live cultures strains undergo numerous in-vitro (see Probiotics Learning Lab) tests documenting their viability at room temperature, and to survive the acidic stomach environment and bile salts.
Featured OptiBac strains
Lactobacillus acidophilus NCFM® is the most well-researched L. acidophilus strain in the world, with over 45 clinical trials. NCFM stands for the 'North Carolina Food Microbiology' research laboratory, where it was first identified in the 1970s. Find Lactobacillus acidophilus NCFM® in 'For every day EXTRA Strength'.
Bfidobacterium lactis BB-12® is likely the world's most well-researched strain of the entire Bifidobacteria genus. It has been trialled and shown to be safe for a number of different populations, including pregnant women, children and the elderly. Find Bifidobacterium lactis BB-12® in 'Bifidobacteria & fibre'.
Lactobacillus reuteri RC-14® & Lactobacillus rhamnosus GR-1® is a very unique combination of strains, that has been clinically proven to reach the intimate area alive. This combination of strains (the two have mostly been trialled as a pair) has over 30 years of clinical research, in more than 26 clinical trials including over 2,500 women. Find Lactobacillus reuteri RC-14® and Lactobacillus rhamnosus GR-1® in 'For women'.
Bifidobacterium infantis Rosell-33 has been scientifically demonstrated to reach the guts of children alive. Unlike L. acidophilus, B. infantis mainly resides in the large intestine or colon of children. Find Bifidobacterium infantis Rosell-33 in 'For babies & children'.
Saccharomyces boulardii is an internationally acclaimed yeast that works in a very different manner to our other strains. Saccharomyces boulardii is actually transient, and has undergone rigorous clinical research to demonstrate, amongst other things, its ability to reach the gut alive. Find 'Saccharomyces boulardii' in our shop.
Lactobacillus rhamnosus Rosell-11 & Lactobacillus acidophilus Rosell-52 is an incredibly well researched combination of strains.This combination of friendly bacteria has over 31 clinical trials in support of them, and have been scientifically proven to reach the gut alive, even during a course of antibiotics. Find Lactobacillus rhamnosus Rosell-11 and Lactobacillus acidophilus Rosell-52 in 'For every day'.
