## Questions & Answers

**Q: Anybody know where to buy lactobacillus reuteri atcc pta 6475 higher than 200 million cut? i need like 5 or 10 billion**
A: Culture it. That is to say,  you can make a yogurt with this as your starter. I have been doing it successfully for a few months.  And using inulin in your milk substrate, your counts may likely approach 500 billion if the thinckness of this yogurt is any indication, although i've not tested the CFUs. If you search for dr william davis yogurt the 1st result should be for making l reuteri yogurt, only thing i do different is i pasteurize my milk to 165 (in microwave so no scorching) and in doing this i have not had to re-inoculate the batches every 5th batch, pull off starter at 12 hours and save in fridge for next batch.

**Q: How do I know this is going to survive the intenstial tract ?**
A: BioGaia’s L. reuteri is the only Lactobacillus probiotic that naturally occurs in the gastrointestinal (GI) tract.  Studies have shown that L. reuteri, when supplemented in the diet, both survives and colonizes the entire GI tract, including the stomach.

**Q: Where is made?**
A: The country of origin for the BioGaia Gastrus is Belgium

**Q: What exactly is the source of the asorbic acid ingredient???**
A: The ascorbic acid in Gastrus is a synthetic L-ascorbic acid.
