@Tammy, I think the correct link is:
https://www.progurt.com/pages/faqs
I was duped for years...very easy to be, especially when one is desperate for relief, so that's why I question everything these days, and always look for references or studies to back up various claims.
One thing that stood out instantly for me was their claim that s. thermophilus was one of the 'strains identical to those found in a healthy human gut
from birth'. I'm not sure any of the strains are found in the gut 'from birth'. It's my understanding that for short period the gut is sterile, and then if one is breast fed, then strains like b. infantis are passed from mother to child, just as one example.
But s. thermophilus is a strain found
in dairy, used specifically to make yogurt. To the best of my knowledge, it's not a human strain, although perhaps it might be found in the stool if one eats a ton of homemade yogurt, or a high-dose probiotic that contains it as one of the strains. The also claim that the 'strains of bacteria contained in Progurt are of human origin, unlike most probiotics, which are of bovine or animal origin'. I can't find any reference or study that suggests s. thermophilus is 'of human origin', although
this specific strain was found in fish.
I could easily -- easily -- be wrong. I'll let you know if I hear anything from the company. If anyone else has any info that independently supports their claim, I hope they'll reply here.
