What are beta-glucans?

Glucans are large carbohydrate molecules made up of multiple units of glucose. They harmlessly mimic microorganisms and are completely natural.

Safe for diabetics?

If beta glucans are made up of glucose, are they safe for diabetics? 1-3, 1-6 beta glucans do not break down into glucose and are safe for diabetics or any one with blood sugar problems.

What are glucans derived from?

1-3, 1-6 beta glucans are derived from a very highly refined and purified version of Saccharomyces Cerevisiae, or brewers yeast.

Which is best for me?

Glucasan+, Glucamune or Betamune75?
Glucasan+ has added Zinc and Vitamin D – essential vitamins and minerals for good immune function. Alternatively Glucamune has no added minerals so is suitable for those taking additional mineral supplements, children and infants and those on a high doses used in a combination with other treatments. Betamune has an independently certified linkage of more than 75% and is for use in combination with other therapies where intensive treatment is required.

Any conflicts or problems?

Are there any side effects, conflicts with other medicines, complications or allergic reactions to beta-glucans? No conflicts or problems of any sort have been encountered in several years of widespread use. Occasionally, on first use, the immune reaction can feel briefly like the onset of mild illness but this passes very quickly.

What about pregnancy or babies?

Are they suitable for children, infants and pregnant mothers? Yes beta-glucan is natural and entirely safe. Very young children and infants should restrict their dose to one capsule per day and if necessary the capsule can be opened and sprinkled on food.

Can I overdose ?

Is there a maximum of tablets one can take and are there any potential ill effects from overdose?
1-3, 1-6 beta glucans are safe even in very large doses. High doses are often recommended by specialists when prescribing beta glucan for use in combination with other therapies. As far as we know it is not possible to overdose on beta-glucan – the only effect of extreme consumption might be nausea as the product is dry matter.

How should capsules be taken?

Ideally you should take the capsules before food to improve absorption but if you have a fragile stomach or find capsules difficult to swallow then with a milk drink or during a meal is ok. Capsules can also be opened and sprinkled on food.

How long before they work?

How long before the support works with your body after you have taken the capsules?
It can take take up to 48 hours for the support to get up to speed. From then on it simply needs to be sustained by regular use of the capsules in accordance with the instructions.

Why have other substances been included?

Why are there other substances in the capsules and what do they do?
There are harmless flow agents in all the capsules and with Glucasan+ there are small (50% NRV) amounts of added Zinc and Vitamin D3. These are essential vitamins and trace elements crucial to immune support. The capsules themselves are made from E464 which is suitable for Vegans.

Why are they so expensive?

Why are Glucasan+, Glucamune and Betamune 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.

Tablets or capsules ?

Can I have tablets instead of capsules and is there an advantage of one over the other?
Tablets require a good deal of tableting material, whereas capsules allow the use of pure 1-3, 1-6 beta glucans. Hence, one capsule can contain twice as much of the active material as an equivalent weight tablet. Additionally, poor tablet design can greatly reduce bioavailability of the active ingredients.

Are they suitable for Pets?

Can I give the capsules to my pet to cut down on vets bills? And if so, in what dosage?
1-3, 1-6 beta glucans are effective in animals and are widely used in animal husbandry. For cats and dogs, a half capsule / day will be sufficient. Pigs would require 1 to 2 capsules / day, horses 4 – 8; the dose is roughly proportional to bodyweight.

When is my immune system low?

When is my immune system not as good as it should be?
The immune system can be compromised by many factors including bad diet, excessive stress, diabetes and irregular eating habits. Immunity can also be impaired by certain medication, drug and alcohol use. In some cases also athletes on intensive training regimes can find their immunity levels reduced. A overall lack of immune stimulation, as a general result of our sanitised and antiseptic environment is however the main cause of your innate immune system not performing at its best.

Should Glucamune be taken with or without food?

We have no clear evidence either way as to whether it is better to take Glucamune (or our other products) with meals or not.  As far as we know, the active ingredient is absorbed either way.  However, you might be interested to know that for the recent study on the effectiveness of beta-glucans on building resistance to colds etc, the participants were given two doses per day, one at breakfast and one at supper.  The study is on our website.   I know people who take with food others who don’t.  Personally, I take some prescription medication and simply add my capsule(s) at the same time, usually after breakfast.
What is important is to take our products for the long-term.  It is the steady build-up and maintenance of immunity that helps.


Does age affect the immune system?

Have young people a better immune system than older people?
Many older people do have reduced immune function, but this is not necessarily due to ageing but more often to poor nutrition. As increasing numbers of younger people are also poorly nourished, impaired immunity can be found in all age groups.

I'm going into hospital. What do I do?

Should I take the capsules before I go into hospital?
Yes. Hospitalisation means stress, exposure to other ill people – and the distinct possibility of ‘superbugs’ so your system needs all the support it can get.

Why are immune systems so different?

Why do some people come down with every bug going, while others remain unaffected? Is it to do with beta glucans?
It may be. Some people are better defended against infection because, for a variety of reasons, their immune systems are in better shape. This may also be because they are generally better nourished.

Are beta glucans prebiotics?

I thought beta glucans were prebiotics – in oats and grains – which improve cholesterol and keep you regular. Is Glucasan+ the same thing?
No. Prebiotic compounds in cereals are 1-3, 1-4 beta glucans and they have no effect on immune function. These are completely different from the 1-3, 1-6 beta glucans in Glucasan+, Glucamune and Betamune75.

Allergic reactions?

I’m allergic to various things – will Glucasan make that problem worse?
No allergic reactions have been detected with beta-glucan, even among people with pre-existing allergies. However, if in the unlikely event you do notice any reaction, stop taking the supplement and consult a health professional.

Auto-immune disease-implications?

I have an auto-immune disease – can I take Glucasan?
Patients with auto-immune diseases such as rheumatoid arthritis have taken beta glucan food supplements without any adverse reaction and noticed positive results.

Candida - can I still take beta-glucan?

I suffer from Candida; can I still take beta-glucan 1-3, 1-6?
No problem. 1-3, 1-6 beta glucans are derived from Saccharomyces cerevisiae, which is totally unrelated to Candida.

Fever/sore throat ?

I felt feverish/had a sore throat when I started taking Glucasan – is this a coincidence?
Quite often the uprating of immune function is heralded by a physical effect like fever or sore throat (as in the onset of illness); as part of what the beta-glucan 1-3, 1-6 does is to (harmlessly) mimic a general bacterial threat. This will pass fairly quickly as your innate immune function gets up to speed.

How do I store the capsules?

Does beta-glucan 1-3, 1-6 have to be stored in a fridge?
No, but it is best stored in a cool place.

How can I order?

Click here to buy from us on-line or phone 0870 042 8423 and ask for Glucasan+, Glucamune or Betamune75.

What else can I use?

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 cerevisiae; but they are not as well researched, and not necessarily as supportive most particularly because there are no established efficacy standards for them. See here.

Can I buy these products in bulk?

Please email for any trade or bulk orders.

Beta-Glucans & Cancer

What role do Beta-Glucans play in preventing or mitigating cancer?
Cancer is seen by many doctors, health professionals and scientists as a breakdown of the immune system. Cancer is rather unlikely to exist or prevail in a body with a healthy immune system. Beta-Glucans are considered immuno modulators which control and control a healthy immune system.

Recovery after an operation

Can beta-glucans help with my recovery after an operation?
The beneficial biological effects of beta-glucans have been described in thousands of scientific studies. These natural fiber molecules are seen as an attractive and low-cost proposition to patients recovering from hospital stays and even cancer-related treatments.
