What Does A Probiotic?

The requirements for a microbe is considered a probiotic are simple. The microbe must be alive when administered, must be documented to have a health benefit and should be administered at levels shown to confer the benefit.

A report on "Guidelines for the Evaluation of Probiotics in Food" considered more complete than levy minimum probiotic experienced a need.

The results were:

* The probiotic should be identified in the genus, species and strain level, using appropriate molecular and physiological techniques.

* The strain must be registered internationally recognized collection of crops so that scientists can duplicate the published research on the strain.

* Tests in vitro and in appropriate animal should be conducted to better understand the physiological qualities of the strain. However, the choice of what tests should be based, is that they are relevant to the role probiotic offered. You must take care not to overextend the findings of in vitro and animal tests have not been validated and has not been shown to be important in the host.

* Before use, the safety of the microbe must be considered thoroughly.

* Controlled studies should be conducted to document a health benefit on the host.

* Ability to keep alive the probiotic at the required levels in the final product through life.

Those with some familiarity in this field may find that this list of requirements does not include such qualities as ability to adhere to intestinal cells, resistance to bile and acid production of bacteriocins, antipathogenic activity, human origin, survive intestinal transit , among others. This is because the array of potential targets for health, hosts, and delivery methods are so diverse that any features beyond those listed above is important for only a subset of probiotics, or because it is unclear whether these benefits are indeed prophetic of the functionality in vitro.

For example, it mentions that the probiotic must survive intestinal transit to be effective. Although there is no doubt that the ability of probiotics to grow and metabolize the intestinal tract according transit may contribute to sickness benefits, there are also cases where this may not be necessary. For example, preliminary research suggests that some probiotics can reduce the levels of Streptococcus mutans, the cause of dental caries, oral microbial community. A health benefit of this type would not require survival through the intestine.

At a minimum, the probiotics should be safe, effective, and should maintain its effectiveness and power through the end of shelf life. This requires a responsible approach by the producer and consumer. The producer must identify strains and storage conditions that will ensure consumers that live probiotic levels remain effective through the end of life. Consumers should store and use the product according to manufacturer's instructions.
