Review: Wow - good service and excellent product - This has been my go-to brand of acidophilus forever. I currently need it because of the heavy antibiotics I need to be on for several weeks. This has always prevented yeast overgrowth (in the vaginal and oral cavity). I also super appreciate the way it was wrapped to ensure it was kept cold while in transit. Thank you for being a caring company. Linda.

## Questions & Answers

**Q: Is this none GMO and organic?**
A: Yes

**Q: Shipped without refrigeration- why?**
A: I’m not sure. Will say I think most of the, “keep refrigerated,” supplements likely are not stored that way in the warehouses. That said, I make cheese and that requires the microbes and starters be kept refrigerated. They ship mostly USPS and there’s no refrigeration there. I just put them in cold storage when I get them. I’ve never had a bad batch of the basic starters. Bacteria are hearty little buggers, so you’ll probably be fine if you toss it in the fridge as soon as it arrives. Hope that helps.

**Q: Why was mine shipped without cold/ice protection? It is not good when arrived? Have to throw out/return now?**
A: Apparently it doesn’t need refrigeration. I thought it did but manufacturer said no. I still refrigerate once opened.

**Q: This product should be refrigerated.  Is it shipped with an ice pack?**
A: It isn’t. But I wrote to manufacturer and was told refrigeration only needed after opening.

### ⭐⭐⭐⭐⭐ Definitely Potent
*by A***R on November 11, 2014*

I've taken probiotics for many years, beginning with a very expensive brand advertised on the radio, and other brands since then. Sometimes I switch for price, or because they quit working for me or I need to increase the dose, or sometimes I get a product that might have been poorly-handled in the heat. For whatever reason, I become unhappy with a brand, so I try another one. After reading reviews this time I decided to try these by Natural Factors. I know probiotics are potent if they: Cause intestinal activity for a few days as I adjust to different organisms - these did. Keep food and environmental allergies in check - yep, working for me very well. Maintain intestinal regularity - good, just as they should. Help immunity from colds and viruses - so far so good. They're small, easy to swallow. I only need to take one a day. I like that these are in a bottle and not blister packs. The attached flip top is very convenient and easy to open. Even though you don't have to, I keep them in the fridge just to make sure they stay as potent as possible.
