ABSTRACT
The use of health-beneicial microorganisms was irst introduced in the beginning of the 20th century. As reported in the previous chapters, probiotics represent alternative therapeutic agents. In order to improve the clinical eficacy of probiotics, optimization will still be achieved by the application of new approaches (Sleator and Hill 2008). Several European Union projects have shown that with coordinated efforts toward a scientiic approach to the selection and application of probiotics, effective functional products can be developed with health beneits for consumers (Saarela et al. 2000). This chapter is concerned with formulated preparations to administer probiotics (medicines or dietary/food supplement).
