Scientific Studies



Before a probiotic can claim it has health benefits, it must be tested in human studies, using the exact bacterial strain.

The most reliable human study is the “placebo-controlled” clinical trial. In this type of study the bacteria strain is tested on at least two groups of human beings. One group is given the test preparation (the test group) while the other is given a dummy preparation that looks and tastes the same as the test preparation, but without containing any test bacteria (the placebo group).

GG probiotic’s health benefits are based on evidence from placebo-controlled clinical trials conducted using its unique GG (ATCC 53103) strain. Its clinical trials are published in renowned scientific and medical journals, such as the British Medical Journal, British Journal of Cancer, the American Journal of Clinical Nutrition and the Medical Journal of Australia.

Unlike many probiotics, LACTOGG® does not “borrow” the results from tests on other probiotic strains and pass them off as its own.  

Judge a probiotic’s true worth not on hearsay, but on the strain’s published scientific and clinical studies. Check that every health benefit is proven!


Does LACTOGG® pass this test? 

Yes.LACTOGG®’s strain now has over 1000 scientific papers and more than 250 clinical trials to back-up its health benefits. It is the probiotic strain which is used and recommended by the medical profession.
