Probiotic means “promoting life”. Probiotics are good bacteria that flourish in the gastrointestinal tract to support healthy digestive and immune function. However, how does one choose between all the choices of probiotics? For us, a probiotic product has to have a clear answer to the following questions:


  • Where the probiotic is originally sourced from?

    • Most probiotics are originally sourced from the mouth or digestive tract of people. There are some studies that show evidence that probiotic bacteria that live naturally in the human mouth could in certain circumstances accelerate tooth decay, caused by the bacteria S.  mutans.

    • PROVIOTIC® is sourced from the Snowdrop flower. PROVIOTIC® does not naturally live in the human mouth and cannot be associated with any risk of tooth decay.


  • Are there major food allergens, such as lactose, gluten, soya or nuts that are part of the probiotic fermentation process?

    • Most probiotics on the market contain traces of one or more of the major food allergens: lactose, gluten, soya or nuts. Prior to using any probiotics, you should inquire whether the probiotic fermentation process yields a final product containing traces of lactose, gluten, soya or nuts. It is also important to note that probiotics that use milk as part of their growth solution cannot be vegan as they contain animal based proteins. These products are not vegan regardless of whether the probiotics are contained in vegetable or vegan capsules, as the major allergens and/or the animal traces are in the actual powder.

    • PROVIOTIC® does not contain any major food allergens as its probiotic growth formula is pure vegetable juice. Thus, PROVIOTIC® is 100% vegan and suitable for those pursuing a clean-eating lifestyle.


  • Has the probiotic been researched by professionals from a reputable academic institution?

    • Many of the probiotics today do not have rigorous scientific research behind their products and very few of them have a prominent US university as a research partner to verify the characteristics of their good bacteria. It is important to inquire about the scientific research that validates any probiotic product.

    • PROVIOTIC's® good bacteria L. bulgaricus GLB44 has been studied by one of the most prestigious academic institution in the United States (


  • What is a CFU and how can one understand what these billions of CFUs actually mean?

    • CFU stands for Colony Forming Unit, or simply a bacterial cell. Thus, the number of CFUs tells how many bacterial cells are there in a probiotic serving. However, since the bacterial strains vary in terms of their size, their enzyme production, and their effectiveness, comparing only the number of CFUs across different strains is like comparing the strength of a group of mammals based purely on their numbers. Elephants and mice are both mammals; yet drawing conclusions about their comparative performance based on their count, not on individual qualities is flawed. This is also the case when it comes to comparing different bacterial strains.

    • The size of PROVIOTIC® good bacteria is 14 m in length, which is one of the biggest among the other probiotic bacteria. This partly explains whyPROVIOTIC® is able to produce the specific enzymes that are so effective against bad bacteria in our in vitro tests. The following tables shows howPROVIOTIC's® good bacteria compares to other probiotic bacteria in terms of size.


  • What are other evaluation criteria are important in the evaluation of a good probiotic?

    • Ability to survive the passage through the stomach by resisting the gastric acidity.

    • Ability to survive in the intestines by resisting the bile acids produced by the liver.

    • Antimicrobial activity against potentially pathogenic bacteria.

    • Ability to reduce pathogen adhesion to surfaces.

    • Ability to attach to the intestinal wall.


PROVIOTIC's® in vitro tests show positive results on all of the above criteria. Beyond its Generally Regarded as Safe (GRAS) status and in vitro tests performed by some of the most reputable US and European universities,

PROVIOTIC's® good bacteria has not been evaluated by the US Federal Drug Administration and there are no significant human trials to meet the requirements for health claims.
