Beta-1, 3D glucan
Linkage Content Level Purity = Top quality Product
The many peer reviewed medical studies that have shown the incredible immune assistance results is based on the the study of one particular beta glucose linkage.
What is this linkage?
Beta glucan is made up of many glucose linkages, however it is the Beta-1, 3D glucan linkage that all the medical research, spanning across two centuries has confirmed it is the one that "turns on" the immune system[1].
The history of Beta-1,3D glucan reaches into the middle of the last century. Dr. Louis Pillemer documented a material that was proven to produce some awesome immune support properties. IHis team coined it "Zymosan". Later in the 20th century another doctor working at Tulane University identified the particular immune method that he described as Beta-1, 3-D glucan. Health-related studies on humans using this compound would some follow. These studies started during the 1970's and have continued up this existing day.
Beta-1, 3D glucan is found throughout nature and has been extracted from several sources.
Below are the most popular sources;
Barley Beta glucan - Usually employed as a source of dietary fiber and heart wellness. This product is the newest kid on the block.
Oat Beta glucan - Similar to Barley glucan as a resource of dietary fiber and heart wellness, you can find this compound in a lot of your common "functional food" goods, like oat-meal.
Mushroom Beta glucan - Studies show mushroom derived glucan help support some immune process function nevertheless not at the level of the best one of them all;
Bakers yeast Beta-1, 3D glucan - By far one of the most researched. This resource is considered "the mother of all Beta-1, 3D glucan's" for its wonderful immune support properties. Not only has it been shown to be the most effective immune support product, but it also has been proven to be advantageous for heart health and a great source of fiber.
Bakers yeast derived Beta-1, 3-D glucan has proven itself the best at producing the highest immunomoduating characteristics of all of the sources.
The Beta-1, 3D glucan linkage is located in the cell wall of bakers yeast and if properly extracted it will remain in it bio-active state. It is absorbed by the peyers patches. These patches are located in the small intestine. The proper manufacturing process will strip away a variety of layers of unwanted carbohydrates, proteins, fats, and other materials that make up a fungus cell leaving only very small residuals of these unwanted by-products. In many products the beta-1, 3D linkage may not present and other compounds like fats and proteins may also be present. Excess fats lower the ability of it being absorbed and high concentrations of manna proteins may lead to possible adverse side effects.
How can you locate a high quality Beta-1, 3D glucan product? The label of a Beta glucan product can be very revealing. Is the actual 1, 3D glucan linkages actaully listed
And how much actual 1, 3D linkage is present. When looking for a Beta glucan supplement to purchase make sure it has all the active linkages listed, like the 1,6 2,3 and 3,6 linkages as well as the 1,3 linkages.
For instance, here's the actual label information located on various Beta Glucan products:

Label 1
|
Notice this doesn't include any kind of reference to Beta 1, 3-d glucan. It merely declares "Beta Glucan complex"
Well, what is that? We do not have a reply for you personally plus it might cost us thousands to preform the assessments needed to discover what was within the supplement. You will find simply to many Beta glucan supplements currently available to test.
Here is another label:

Label 2
|
This one declares "Beta Glucan (1,3/1,6) 500mg", observe however it doesn't supply the percentage amounts of the individual glucose linkages.
Just how much 1,3/1,6 linkage can there be within this supplement 10%, 20%, 30%, etc...
Now lets take a look at a label of a actual Beta 1, 3-d glucan supplement:

Label 3
|
Notice exactly how this supplements label lists every single glucose linkage and also the phrase "Beta 1, 3-D glucan Complex".
This gives us a conclusive answer on what precisely is included in the supplement therefore we are able to make a educated choice on whether or not to buy it.
The University of Louisville conducted an independent study on the most popular immune support products. The majority of the products tested were Beta glucan products. The results were very revealing. To learn more about which product produced the best results click here.
