What is Beta glucan?
Beta glucan is a scientifically proven biological defense modifier (BDM) that nutritionally potentiates and modulates the immune response. As a supplement, after swallowing orally, Beta glucan is ingested primarily through macrophage and dendritic immune cells, to nutritionally and safely yield, through immune response potentiation and modulation, in many instances various therapeutic healing effects generated by the immune cells.
For many years Glucans have been investigated (History) for these immune enhancing properties, particularly their ability to activate macrophage immune cells and NK-Cells, plus in turn, the T-Cells, and B-Cells including selected cytokines and complement.
Poly-branched B-1,3-(D)-Glucans are naturally occurring polysaccharides, with or without B-1,6-(D)-glucose side chains, that are integral cell wall constituents in a variety of bacteria, plants and fungi. Glucan receptors to deliver non-self derived glucan to the immune response have been identified on macrophages, dendritic cells and other cells. The Beta-1,3-(D)-glucan with Beta- 1,6-glucan linkage extracted from yeast cell wall (Saccharomyces cerevisiae) has been shown to act as a potent non-specific immune-activator.
The scientific literature on glucans is voluminous over many decades, and there is also a considerable body of patent literature. This Index is not intended to be a complete compilation of all beta glucan research, but rather is keyed by health condition and targeted to research on yeast-cell-wall-derived Beta- 1/3,1/6-glucan.
This indexing format varies from standard research classified by "researcher(s)" to make finding applicable research to a specific health condition easier for both the scientific and nonscientific user. As a note, particulate insoluble beta glucan is the glucan form in nutritional dietary supplements, while soluble glucans are primarily utilized in pharmaceutical applications. Particulates are not generally safe as injectables.
Functions in the Body:
Beta-1,3 glucans improve the bodyís immune system defense against foreign invaders by enhancing the ability of macrophages, neutrophils and natural killer cells to respond to and fight a wide range of challenges such as bacteria, viruses, fungi, and parasites.
Symptoms and Causes of Deficiency: Beta-1, 3 glucans do not occur naturally in humans, hence no deficiency condition exists.
Absorption: For best results, Beta 1, 3-D glucan should be taken on an empty stomach. Enterocytes reportedly facilitate the transportation of beta-1, 3 glucans and similar compounds across the intestinal cell wall into the lymph where they begin to interact with macrophages to activate immune function.
Radiolabeled studies have verified that both small and large fragments of beta glucans are found in the serum, which indicates they are absorbed from the intestinal tract. M cells within the Peyerís Patches physically transport the insoluble whole glucan particles into the GALT.
Although beta-1 3 glucans occur in bakerís yeast, seaweed, grains such as oats and barley, and numerous mushrooms, they are not readily usable in their natural state. The indigestible cell walls of these substances must be processed in order to free up the beta-1, 3 glucans and make them available for useful purposes.
