Biotec BetaGlucans’ work on beta-glucan activity has its roots in discoveries made at the University of Tromsø, Norway, and Biotec Pharmacon’s early work developing a portfolio of beta-1,3/1,6-glucan products that have been sold worldwide in the animal health and consumer markets.

The company has closely collaborated with leading research groups in Norway, Europe and the United States of America, executing projects that have revealed novel insights for the mode of action and potential uses of beta-glucans[1-7]. During the last 25 years, beta-1,3/1,6-glucan has been introduced as a feed additive to improve health and performance of farmed shrimp, fish, pigs, chicken, laying hens and calves, and of horses and pet animals[8–17].

In recent years, awareness of and general research into the immune system-boosting potential of beta-glucans has increased within biomedical and clinical research communities.

Building upon the foundation it laid in animal health and consumer products, Biotec BetaGlucans has invested major resources in R&D to better understand how beta-1,3/1,6-glucan’s modulation of immune mechanisms can be used to treat or prevent immune-related disorders and diseases. As a result, the company has developed a soluble beta-1,3/1,6-glucan (SBG), which is the active ingredient in Woulgan Bioactive Beta-Glucan Gel, an advanced wound healing product.
