How does Wellmune help strengthen the immune system?

Wellmune is taken up into the body through specialized immune tissue in the intestines. There, immune cells engulf Wellmune and degrade it into smaller fragments that bind to neutrophils, the most abundant immune cells in the body. Primed by Wellmune, neutrophils more quickly recognize and kill foreign challenges such as bacteria or viruses.

What is the method used to measure the active component in Wellmune?

Wellmune Glucan Enzymatic Method (GEM®) is a solution to shortcomings of traditional glucan assays. The inability to distinguish or differentiate between polysaccharides often results in an overestimation of the actual beta glucan content. GEM relies upon selective enzymes that are specific for beta glucan and break it down to glucose while leaving other polysaccharides intact. The GEM analytical methods were adopted by the United States Pharmacopeia for the development of the first official monograph for beta glucan from baker’s yeast. The monograph was published in the Food Chemicals Codex and the USP Dietary Supplements Compendium, internationally recognized compendiums of standards for the purity and identity of food and supplement ingredients.

What scientific publications provide information about Wellmune’s technology?

Research on Wellmune has been published in leading peer-reviewed science and medical journals, including Nature, Nutrition, Journal of Nutrition & Food Sciences, British Journal of Nutrition, Journal of the American College of Nutrition, Journal of Sports Science and Medicine, and Journal of Applied Research. A complete listing of journals can be found on our Research page.
