Don't just take our word for it

There have been many scientific studies which identify the benefits of probiotics in general and Lactobacillus bulgaricus specifically.

The resistance to biological barriers i.e. gastric juices, bile salts etc. is a key factor in the beneficial effectiveness of probiotic bacteria.

"Lactobacillus bulgaricus was the lactic acid starter species with the best probiotic characteristics among the starter species tested."
C.G. Vinderola, J.A. Reinheimer – Food Research Int. (2003).


The ability to adhere to the intestinal mucosa is also a vital element in the effectiveness of a probiotic bacteria strain and is therefore one of the main selection criteria.


"The adhesion of Bifidobacterium lactis Bb12 to a mucus model was more than doubled by the presence of L. bulgaricus. Other lactobacilli tested did not affect the adhesion."

"Lactobacillus bulgaricus was more effective than L. casei & L. acidophilus in enhancing the number of IgA secreting cells in the bronchus mucosa."
