Pleuran belongs to a group of glucose polymers commonly called beta-glucans demonstrating biological response modifier properties. These immunomodulating properties render the host more resistant to infections and neoplasms.[2]
In a study published in December 2010, pleuran demonstrated to have a protective effect against exercise-induced suppression of immune cell activity (NK cells) in subjects taking 100 mg per day.[3]
In another study published in 2011, pleuran reduced the incidence of upper respiratory tract infections and increased the number of circulating NK cells.[4]
Pleuran is also being studied as a potential immunologic adjuvant.[5]
