Probiotics are live micro-organisms which, when administered in adequate amounts, confer a health beneﬁt on the host.
The term is currently used to name ingested microorganisms that are associated with beneficial effects to humans and animals. They provide health benefits when consumed.
As for human the health benefits can also impact bees.
The term came into more common use after 1980. The introduction of the concept is generally attributed to Nobel scientist Élie Metchnikoff, who in 1907 suggested that "the dependence of the intestinal microbes on the food makes it possible to adopt measures to modify the flora in our bodies and to replace the harmful microbes by useful microbes".
Commonly claimed benefits of probiotics include the decrease of potentially pathogenic microorganisms, the strengthening of the immune system, the protection of DNA.
Live probiotic cultures are available in fermented dairy products and probiotic fortified foods. However, tablets, capsules, powders, and sachets containing the bacteria in freeze-dried form are also available.
Pobiotics have to be alive when administered. For such reason their packaging is a crucial issue and to keep them alive is also important that they have food suitable for them available when you want to reactivate the lyophilazed bacterias.
