Review: Recommend this probiotic - Great price and love bulk order ; great product line
Review: Great for Yogurt and Well-Being - I’ve been using Swanson’s L. reuteri purchased on desertcart to make yogurt, and it works very well. The culture is reliable, and the yogurt comes out consistently good. Beyond that, I’ve noticed I feel more content and have a better sense of well-being since I started using this brand. I can’t say for sure if it’s the L. reuteri doing its job, but that’s how it feels to me. Easy to use, effective, and a brand I trust — I’ll keep buying this.

## Questions & Answers

**Q: What are the 16 strains contained in this product? I don't see a place that lists them.**
A: GOTTAHAVEIT IS HAPPY TO HELP YOU WITH THIS:Supplement FactsServing Size 1 Veggie Capsule 	Amount Per Serving	% Daily ValueFOS (Fructooligosaccharides)	50 mg	*ConcenTrace® Trace Mineral Complex(from the Great Salt Lake, 72 naturally occurring minerals, plus other minerals found in seawater)12.5 mg	*Bifidobacterium longum	430 million viable organisms†	*Lactobacillus acidophilus	430 million viable organisms†	*Bifidobacterium bifidum	180 million viable organisms†	*Bifidobacterium breve	180 million viable organisms†	*Bifidobacterium lactis	180 million viable organisms†	*Lactobacillus brevis	180 million viable organisms†	*Lactobacillus bulgaricus	180 million viable organisms†	*Lactobacillus casei	180 million viable organisms†	*Lactobacillus helveticus	180 million viable organisms†	*Lactobacillus plantarum	180 million viable organisms†	*Lactobacillus reuteri	180 million viable organisms†	*Lactobacillus rhamnosus	180 million viable organisms†	*Lactobacillus salivarius	180 million viable organisms†	*Lactococcus lactis	180 million viable organisms†	*Streptococcus thermophilus	180 million viable organisms†	*Bifidobacterium infantis	90 million viable organisms†	**Daily Value not established.†Colony-Forming Units (live bacteria) at time of manufacture.May contain trace amounts of milk from fermentation media.

**Q: Do these need to be refrigerated?**
A: No, these do NOT have to be refrigerated. I have been taking these for over 2 years. I am copying and pasting this informational page directly from Swanson Vitamins, the maker of this probiotic....please read the maker of this vitamin states NO refrigeration needed....http://www.swansonvitamins.com/health-library/products/dr-langer-high-potency-probiotic-delivers-optimum-gi-support.html

**Q: Two questions:  does this work better than swanson probiotic 4?  also, how large are the capsules compared to swanson probiotic 4?  thank you.**
A: Thanks for your questions!  While we are unable to say which will work better, we are happy to compare the two items.  Both have 3 billion viable organisms, with the 16 Strain Probiotic offering a wider variety in the types of strains.  Both have a prebiotic to help the probiotics in the intestines (125 mg for Probiotic 4 and 50 mg for 16 Strain Probiotic), and the 16 strain also includes a small amount of a trace mineral complex (12.5 mg).  The 16 Strain Probiotic is the smaller capsule.  We hope this information helps!

**Q: If FOS feeds the bad bacteria, why is it in here?**
A: They put it there to feed the beneficial bacteria.but it's acting against people how have candida,  sibo or food allergies because it stimulate the levels of E coli. It is best to get it from your diet like artichoke,  onions, garlic. I hope it helps.
