New probiotics available for IBS and IBD

Probiotics are a new and evolving form of treatment for bowel disorders. Probiotics have been proven to work to prevent to some degree for diarrhoea associated with antibiotics. There is some good work now suggesting a role in irritable bowel syndrome.
Some of the problem in evaluating this treatment is the wide variety of products with different bacteria, different doses and differing viability of the bacteria. It seems likely that these details - particularly the strain type - may be very important and different strains may be required for different indications

I have been very pleased with Inner Health Plus which is a capsule containing equal amounts of Lactobacillus acidophilus and Bifidobacterium - 25 billion bacteria per capsule. This is the sort of amount of bacteria that is likely to work. Check out the website for more details (www.innerhealh.co.au). There is also a probiotic that has been extensively studied for IBS - "IBS Support - Lactobacillus plantarum"
