Beta-glucans: Beta-glucans are polysaccharides made up of linked glucose building blocks. They are found in oats, barley, yeasts and various mushrooms.
The material composition is interesting. The spatial linkage of the sugar building blocks differs between cereal and mushroom beta-glucans. This is why origin and chemical structure are important for assessing them.
In herbal lore, the distinction between leaves, fruits, seeds, roots and bark is important. The individual parts of a plant can contain very different groups of substances. A figure such as 4:1 or 10:1 describes the ratio of starting material used to the amount of extract obtained, not automatically the concentration of a single active ingredient.
A look at the form of raw material used reveals further special features. Beta-glucans are polysaccharides and belong to the indigestible dietary fibres. They occur naturally in the cell walls of various cereals, among other places.
In the Fairvital product Beta-Glucan 500mg, the formula shows the form and amount of the ingredients used. According to the list of ingredients, these include beta-glucan (contains 70% polysaccharides from oats). The composition table states 3000 mg of beta-glucan (of which 2100 mg is polysaccharides) per 6 capsules. The pack contains 90 capsules.
