Give Your Customers the Gift of a Healthy Immune System This Holiday Season

Staying well and maintaining a healthy immune system can be especially challenging during the holiday season for several reasons:

  • The immune response isn't as effective during the colder months (compared to warmer months.) 1
  • Chronic stress (prevalent during the holidays) can cause almost all measures of immune system function to drop across the board. 2
  • A poor diet (not unusual during the holidays) can compromise the otherwise healthy immune system. 3

How to Keep the Immune System Healthy During the Holiday Season

Of course, the last thing you want is for your immune system to be weakened during the holidays, yet this is all too often the case and may result in the upper respiratory tract to function at a less than optimal level. 4 However, there is something that can be done to help. It’s called beta 1,3/1,6 glucan.

What Is Beta 1,3/1,6 Glucan?

Beta-glucans comprise a very diverse group of polysaccharides, with immune modulatory properties. Beta-1,3/1,6-glucan derived from the yeast Wellmune WGP® is the most studied beta-glucan. Renowned in terms of immune stimulatory efficacy, mode of action and safety, Wellmune WGP® beta 1,3/1,6 glucan is hence considered superior to beta-glucans from other sources.

How Does Beta 1,3/1,6 Glucan & Wellmune WGP® Help Maintain a Healthy Immune System?

A unique substance called beta glucan is present in a special strain of yeast called Wellmune WGP® -- which in turn has been well researched. In fact, once swallowed, immune cells in the gastrointestinal tract take up the beta glucans and transport it to immune organs throughout the body. While in the immune organs, the beta glucans are broken down into smaller fragments, and are then slowly released over a number of days. Fragments of the beta glucans bind to the most abundant immune cells in the body priming and strengthening their key immune functions. It is important to note that beta glucans boost immune function to maintain a healthy immune system without overstimulating it. Also, multiple human clinical studies have shown that this Wellmune WGP® form of beta glucans is effective in promoting the health of upper respiratory tract.

Research and Evidence on how beta 1,3/1,6 glucan can lead to healthy immune system

In a random, double-blind, placebo-controlled trial 5, 250 mg/day of this beta 1,3/1,6 glucan or placebo was given to 100 healthy individuals during the winter season when upper respiratory health might be compromised. The results were that beta 1,3/1,6 glucan helped maintain upper respiratory function more effectively compared to the placebo group, and the ability to "breathe easily" was significantly improved in the beta 1,3/1,6 glucan group as well. Likewise, additional studies 6-7 have shown that 250 mg/day of Wellmune WGP® beta glucan reduced upper respiratory tract infection (URTI) symptoms and improved mood state in stressed subjects, compared to placebo.

Since strenuous exercise is known to suppress immunity for up to 24 hours, another study 8 with 182 men and women examined if 250 mg/day of Wellmune WGP® could positively affect the immune system of individuals undergoing intense exercise stress, and help maintain upper respiratory health. The results showed that Wellmune WGP® did help maintain upper respiratory health compared to placebo, and was also associated with a 32% increase in specific immune cells. Other research 9-10 has shown similar benefits with this beta 1,3/1,6 glucan in association with intense exercise.
