Nutritional Supplements

Recent studies have revealed that the human immune system has adapted as a result of facing constant challenges, responding to attack by up-regulating its state of readiness and effectiveness on a continuous basis.    

In today’s sanitised environment however, our immune systems have relatively little to contend with. This has made them less efficient.

A clinical human trial Published January 23rd 2013 in the European Journal of Nutrition, based on a double-blind, randomized, placebo-controlled, multicentric study in healthy subjects, showed that beta-glucan 1-3, 1-6 helps prevent colds, improves symptoms and increases the body’s potential to defend against invading pathogens: Click for Study Details

Glucamune and Glucasan+ and Betamune75 are made from highly refined beta-glucan 1-3,1-6, recognised as the finest immuno-modulator available.

Only the highest quality standardised extract of Beta Glucan 1-3,1-6 is used in Glucasan®+, Glucamune and Betamune75 where the beta-glucans are specially purified. They have no known side effects, are non-allergenic, suitable for vegans and professional athletes and are Clinically Tested.

Are there other things to naturally support my immune system?

Aloe vera, Echinacea, shiitake and meitake mushrooms and other natural materials have been shown to provide immune system support. In some cases, the active molecules are similar to the 1-3, 1-6 beta glucans in Saccharomyces cerevisiase; but they are not as well researched, and not necessarily as supportive, most particularly because there are no established efficacy standards for them. Here are some examples:

Glucasan, Glucamune and Betamune versus other current nutritional supplements:

Vs. Echinacea

Echinacea - found to be ineffective protecting against respiratory tract infections such as coughs and colds (Grimm & Muller '99, Barrett et al 02, Kreutzfeld '06); ineffective or not proven (Caruso & Gwaltney '05, Carr & Nahata '06, Linde et al '06).

Vs. Aloe Vera

Aloe Vera - may kill immune cells (Ramamoorthy & Tizard '98). Ineffective against viruses (Unsinger ‘97)

Vs. Pro biotics

Pro biotics - efficacy only against gastrointestinal infections

Vs. Goldenseal

Goldenseal - no in vivo evidence. Linked to potentially fatal adverse effects
(Bhowmick et al ‘07)

Vs. Cat's Claw

Cats Claw - interesting anti-inflammatory properties (ie Mur et al '02), but no in vivo evidence of immune activity

Vs. Antioxidants

Antioxidants - may even be harmful (Bjelakovic & Gluud ‘07)

Why is a good beta glucan 1-3, 1-6 supplement so expensive when yeast is so cheap?

1-3, 1-6 beta glucans need to be very carefully refined, for two critical reasons. First, the material must be purified and the particle size must be carefully controlled, to enhance bioavailability and to achieve maximal absorption. (Beta Glucan particles need to be less than 20µ to be maximally effective). Second, the receptors that trigger the immune system are fragile and cannot be damaged during a series very carefully controlled purification processes.


Will any of these conflict with other treatments, minerals, vitamins or medicines?

1-3, 1-6 beta glucans have no known conflicts and can be taken in large doses without hazard.

Derived from natural yeasts, beta-glucans used, until relatively recently, to be a substantial part of the human diet. There are no recorded cases of illness or allergy or any reaction to any of the products offered by Vitalize - the core elements of which have been available and and widely used in the UK since 2004.

"I was working ridiculous hours setting up my own business and hadn’t had a holiday for two years. My energy was rock-bottom and I was getting colds and sore throats all the time.
A nutrition expert told me about these tablets, and they've made the world of difference, I totally believe in these, they’ve kept me going."

More than 1,500 scientific papers have investigated the roles, safety and efficacy of beta glucan for more than 40 years - "beta-1,6-glucan with beta-1,3 side chains shows remarkable immune-enhancing activities"

Beta- Glucan 1-3, 1-6 is derived from the cell walls of the 'friendly fungus', baker's yeast. It supports the innate immune system by exercising it, making our defences more alert to invading viruses and bacteria.


"Beta-Glucans may also promote killing of iC3b-opsonized tumour cells engendered by administration of anti-tumour mAbs.

In this study, we report that tumour-bearing mice treated with a combination of beta-glucan and an anti-tumour mAb show almost complete cessation of tumour growth.
