Probiotics are micro-organisms, or live bacteria that are believed to have a positive impact on your health when consumed. The World Health Organization‘s 2001 definition of probiotics is “live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host”.


Bacteria is often something which is thought of as causing illness and disease but the truth is your body is full of ‘good’ and ‘bad’ bacteria (this good and bad definition is probably an oversimplification of what is really going on). Probiotics are thought of as good bacteria which can improve the health of your gut and intestinal tract. Probiotics are found naturally within the body but can also be found in foods or consumed in supplements.
