Types Of Live Cultures - Our Live Culture Strains
Specific live culture strains for specific conditions
At OptiBac we specialise entirely in live cultures, and in particular we use different strains for different groups of people and for different reasons. Recognising that different types of friendly bacteria can have different properties (and that growing research continues to demonstrate this), we aim to offer each of our customers a specific supplement to support their individual needs. When it comes to live cultures, it is not a question of 'one-size-fits-all'!
What is a live culture 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. The example above, L. acidophilus NCFM®, is thought to be one of the most researched live culture strains in the world. Find out more about Lactobacillus acidophilus NCFM®.
Viable, effective strains
As well as selecting the optimum live culture strains to target your personal health needs, 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 and bile salts in order to reach the intestines. It is furthermore important that the strains are capable of adhering to the gut wall lining, so that they can in turn multiply and colonise the gut with good bacteria. The OptiBac live culture strains undergo numerous in-vitro tests documenting their viability at room temperature, their ability to survive the acidic stomach environment and bile salts, and their adhesion capabilities inside the gut.
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.
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.
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.
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.
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.
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.
