What does FOS stand for in probiotics?

FOS stands for fructo-oligosaccharides, which  are commonly used as an alternative sweetener in some foods and medicines. This water-soluble carbohydrate is composed of short fructose chains, which the human body is unable to digest.

What are the benefits of fructooligosaccharides?

If you take fructooligosaccharides they will pass through your digestive system undigested until they reach your bowel where the live bacteria use it as a food source. The result is a rapid growth in the 'live' bacteria, such as Bifidobacteria and Lactobacillus species. After just two weeks of taking eight grams of FOS daily, research suggests it can significantly increase the number of beneficial bacteria in your gut by up to ten times.

Is fructooligosaccharides safe in pregnancy?

Yes. Lamberts FOS is suitable for all ages, including children and pregnant women, as well as those on yeast-free diets and those on medication. It can be used on a long term basis too!

How much FOS should I take?

This product may be used in one of two ways:

  1. At low doses FOS acts as a prebiotic (bowel 'conditioner').
  2. At larger doses FOS conditions the bowel and also helps maintain regularity.

If any of these intake levels cause excessive flatulence then to reduce the dose and gradually build up. The flatulence is a positive sign that FOS has reached the bowel and is feeding your 'friendly' bacteria. As the bacteria consume FOS a gas is produced which can lead to some flatulence at first however after a few days this will disappear as further 'friendly' bacteria develop and absorb the gases. For intakes over 10g (or 5g in children); dividing the intake into 2 daily doses 1 at each end of the day will help reduce flatulence.

FOS may cause temporary bloating. This is a short-term effect and once your system 'speeds up' the bloating will disappear. If bloating continues for more than 3 days then reduce the daily intake of FOS.

Be sure to drink at least 2 litres of fluids a day.
