Probiotics come in many different forms such as probiotic yoghurts and fermented milk drinks. While Health food stores and pharmacies often have probiotic powders and capsules (some of which claim to be suitable for infants and small children).

Prebiotics:-These are an alternative way of changing the levels of the different types of bacteria in your gut. They're food supplements that encourage growth of the friendly bacteria already in your gut.

Friendly bacteria restore intestinal balance, which results in

• the prevention of adherence of unwanted microorganisms 
• the production of a wide array of antibacterial and antifungal compounds 
• improved resistance against bacteria like E.coli, Salmonella, and H. pylori 

In many respects, friendly bacteria can be thought of as having "adaptogenic" effects on your immune system. They appear to modulate the nonspecific immune response differently in healthy and hypersensitive subjects.

In order to use the word 'probiotic' on a food label in Australia, a product must have at least 1 million bacteria per gram, but it's thought you need about 10 million bacteria per gram to ensure they make it safely through to the intestine.

But most preparations don't tell you how many live bacteria they contain, Choice found. Manufacturers do their own measurements, and some UK studies have found that many products on the market contained doses of bacteria too low to be effective.
