It is distributed in the UK by JRBiomedical and will be sold through high street chain Boots Dr John Rees, medical scientist and founder of JRBiomedical, said: "Re-introducing beta glucan into our diets primes our immune system, making it better equipped to fight common and mutating viruses like colds and flu.
The study also demonstrated that soluble glucans bind to human neutrophils, but not equally.
5, 1995--According to researchers, a nutritional product comprised of a specific beta glucan from the cell wall of yeast can be of benefit to persons with impaired immunity from any cause, persons undergoing chemotherapy or radiation treatment, persons who exercise intensively, persons with a high risk of atherosclerosis or persons with low energy levels.
Placebo capsules were 250 mg of rice flour; BETA-GLUCAN capsules were 250 mg of BETA 1,3/1,6 GLUCAN isolated from the yeast Saccharomyces cerevisiae.
After a century and a half of research, (1) studies have shown that beta glucans act as immunomodulator agents, meaning they trigger a cascade of events that help regulate the immune system, making it more efficient.
Bio-Glucan contains a 250mg/capsule of Wellmune WGP - a form of beta 1,3/1,6 glucans.
Although the performance of this assay does not appear to be affected by the presence of antifungal therapy, it is very sensitive to glucans that naturally reside in the environment.
These particular glucans are cell wall components of fungi, and have been considered surrogate compounds to monitor environmental exposure to fungi, which are increasingly associated with poor indoor air quality.
The molecular architecture of fungal walls remains elusive because of difficulty in correlating chemical composition with the ultrastructural layers and uncertainty concerning the linkages connecting major cell wall polymers: glucans, mannan, and chitin.
The glucans, particularly the [beta]-glucan, are often found in conciderable amounts.
Microorganisms and microbial components such as bacterial endotoxins and mold glucans present in house dust are believed to be important (5,6), but it is not yet clear which components primarily account for the observed effects.
ARS researchers attribute Oatrim's antioxidant function to something other than its beta glucans -- soluble fibers known to lower cholesterol.
