Rated 4.6 out of 5 by 190 reviewers.
Rated 5 out of 5 by has worked very well for me and my wife February 24, 2016
Rated 5 out of 5 by Gut improvement I have been taking this supplement for several months & have noticed that my digestive system functions much more predictably than before using it. November 7, 2015
Rated 5 out of 5 by I have been looking for years for a probiotic that works for me. Finally, I have found it. I love this product. October 26, 2015
Rated 5 out of 5 by Easy Solution This worked when other probiotics had not. Can't beat the price! September 25, 2015
Rated 5 out of 5 by Very helpful probiotic Tried other probiotics but this is the most effective for me. I feel better taking it. Also, like the fact it is a blend and a veggie formula. I believe that makes it more effective. I would strongly recommend this one. March 22, 2015
Rated 5 out of 5 by Helps digestion It seems to reduce my stool, indicating that more food is being digested. March 11, 2015
Rated 3 out of 5 by Would not buy it because: Swanson has many great products. I love their Organics. I wouldn't buy this and any products which may/or contain toxic ingredients: magnesium stearate, silica. February 20, 2015
Rated 5 out of 5 by Very happy I have noticed a great improvement. There is no doubt that this product works. IF I had one suggestion it would be a wish for greater potency. Even at one a day I still have seen such an improvement that I will be a regular customer for life. February 20, 2015
Rated 4 out of 5 by Great product poor packaging This product takes care of digestive problems but the packaging is terrible. If you have problems like I do one bottle is about 20 days worth. This company insists on packing their products in teeny tiny bottles so that you must pay for the packaging and not the product. Swanson's, how about a package of 240 or even more, betcha you could lower the price by 10 to 15% if you did, HUH? October 21, 2014
Rated 5 out of 5 by Great product! This works better than other probiotics I have tried, and costs less. What's not to like? October 21, 2014
Rated 5 out of 5 by Great Probiotic for a Great Price I previously used Dr. Langer's 16 Strain Probiotic and while I thought it worked well it was pretty pricey. Came across Swanson's probiotic 4 on sale and figured I'd give it a try. We have been using this one for several months now and I have to say I'm quite pleased in quality and price. October 12, 2014
Rated 2 out of 5 by Didn't do much First couple times I took it, I had a bit of nausea, along with a weird taste in my mouth, but that didn't happen afterwards. Was hoping it would reduce my excessive gas problem, but it didn't seem to do much for that. May 31, 2014
Rated 5 out of 5 by Probiotic-4 This seems to be helping with digestion and I will keep it with my daily routine. May 15, 2014
Rated 5 out of 5 by This is the one! I've tried quite a few probiotic formulas, and this is the one I will stay with. Noticed the results I wanted right away, and am very pleased. No side effects of any kind. Great price on the BOGO list. May 5, 2014
Rated 4 out of 5 by The Must Have You can forego just about any supplement - but always have probotics. This is a great price and an effective probiotic. April 27, 2014
Rated 3 out of 5 by I did the yogurt making test and it was a long time to gel up so I am thinking that the quality is average but the price is very good. April 21, 2014
Rated 3 out of 5 by Didn't work for me I eat a healthy diet: very little sugar, no white bread, only whole grains, raw+cooked vegetables. I knew this probiotic was wimpy but with my diet I thought it would be enough. Guess not. April 18, 2014
Rated 5 out of 5 by I recommend this product I have been using this product for a year. It has been very beneficial in keeping me regular. I take one per day. I just reordered another year's supply. March 9, 2014
Rated 5 out of 5 by probiotic 4 Seems to do the trick for me...keeps everything running along smoothly .I just take one in the morning and one at night... The value is great compared to some others I have tried that are much more expensive .this is all that I need. February 9, 2014
Rated 5 out of 5 by My Friendly Flora With 87% of the body's immune system in the gut, I depend on this product for my friendly flora. December 31, 2013
Rated 5 out of 5 by Great item! Best pro-biotic Swanson sells. December 29, 2013
Rated 5 out of 5 by love it! Have tried other probiotics but not with the same success I have with Swansons. Reasonably priced, convenient and quick shipping make it so easy to never run outl December 14, 2013
Rated 5 out of 5 by Quality Product for Less This product compares to the higher priced probiotics one finds in the drug store. Swansons offers it for much less at a similar high quality. December 13, 2013
Rated 4 out of 5 by Great value Great value for the price. Works just as well if not better than the more expensive brands. December 12, 2013
