You're only going to find one twelfth of the different bacteria that are in Spagyri-Zyme Probiotic Enzyme in other probiotic products. It is in a class of its own because of the types and the synergy of bacteria that are found in it. It has MANY more different strains of bacteria in it than any other probiotic you will ever find. It does have some crossovers with the Lactobacillus species and sometimes you will find some products with Saccharomyces species, but there are at least 9 strains of other bacteria that you will not find in any other product. Also, other probiotics are usually not in a live fermented form, but rather they are in a freeze dried isolate form- when it is in a live fermented form, it contains the prebiotic, probiotic, and postbiotic ferment that is completely stable at room temperature and therefore does not require refrigeration. There is an enormous difference between a live fermented product and an isolate. Refrigeration is recommended for Spagyri-Zyme, but not necessary because of this. Also, Spagyri-Zyme has bacteria that from enzymatic reactions within the body that absolutely no other supplement provides. So it's in a class all of its own and can't be compared to other probiotics - in fact, every other probiotic product on the market is drastically different both in terms of bacterial composition as well as formulation standard.
