Natural FactorsAcidophilus & Bifidus Double Strength, Probiotic and Prebiotic Formula, 180 Capsules

They work! My digestive system has improved.

For years I bought what I thought was a helpful Acidophilus brand, and attributed my sensitive stomach to nerves. I learned long ago to avoid artificial sweeteners, and not just because I do not care for the taste. I only just discovered that *all* alcohol sugars have a side effect of bloating and diarrhea to some degree. The most popular of these: erythritol (most digestible), isomalt, lactitol, maltitol, mannitol, sorbital, xylitol, and HSH (hydrogenated starch hydrolysate). I also found that my chewable B12 and Zinc, and protein snacks had alcohol sugars. I eliminated alcohol sugars from my diet and, surprise, I no longer have a sensitive stomach! I have switched all of my supplements to the Natural Factors brand. (I also found a new brand for protein.)

Great Product

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.

Daily therapy.

I have been using this product for years… Love the results. Would definitely recommend. I usually purchase at a local store, first time purchasing on Amazon. Price was a little bit cheaper, but I was already ordering other things so it worked out fine. It is kept refrigerated at my local store, I’ve not received this yet, curious if it will be refrigerated as well?

I’ve been looking for a pro- biotic for a long time. I’ve tried different brands, but this one is my favorite. It has helped with gut issues, and it really helps to keep me “regular”. Age effects the gastric system. The older you get, the older the system. Pro-biotics hello to revive that system. These are economical and work wonders!! I highly recommend.

Product is great, however delivery WAS NOT. Ordered through Prime and said 1 day delivery which did not happen. Got another delivery date it changed approximately 5 times before they were delivered. Ordered July 18th and they were delivered August 8th. Too long.
