If you liked our original Colon Tone supplement, you'll love our Pro-Oxy-Biotic. Like its predecessor, it supplies magnesium hydroxide to gently support healthy elimination.* Plus, Pro-Oxy-Biotic goes beyond the original formula to provide healthy prebiotic arabinogalactan, a unique fiber that encourages the proliferation of healthy gastrointestinal bacteria, plus a special probiotic blend of select strains known to colonize in the lower bowel. With 5 billion viable probiotic organisms per capsule at time of manufacture, plus prebiotic fiber and magnesium hydroxide, Pro-Oxy-Biotic is a powerful yet gentle comprehensive approach to colon health.*

Customer Ratings & Reviews

Pro-Oxy-Biotic is rated 4.3 out of 5 by 28.
Rated 5 out of 5 by from It works~ Taken as recommended, this product really works and without any discomfort. The pills are actually a little sweet on the tongue, which I thought was interesting. A very gentle remedy. Enjoy.

Rated 3 out of 5 by from Not what it used to be This is the product that replaced 'Colon-tone' It, in no way is as effective. It does somewhat work but not the same results obtained from Colon-Tone Would like to see the return of the original formula

Rated 5 out of 5 by from Great results This alleviated all of the problems my hubby was having. It works overnight just as stated and it works with only 1 a night. Great product!

Rated 5 out of 5 by from Fantastic Product! This is the best colon tone product I have ever used. It is so gentle but effective, with no side effects.

Rated 5 out of 5 by from Works well This product does as stated. While using the minimum dose the label says to use, I get the results I was hoping for. Other products of the "oxy" line that i have tried in the not so distant past, I would have to take max dose and then it was still slow going. I like this one so well, I just reordered 2 more bottles. I will be set for a good while now!

Rated 5 out of 5 by from Such A Great Product This product is wonderful. It does what it says it will and it is both super effective and very gentle at the same time. It's the best product of its' kind that I have ever used. I try to never run out because it really helps me. It's one of the reasons I am a loyal Swanson's customer. I sincerely and highly recommend it to anyone considering it.

Rated 4 out of 5 by from the Colon Tone Replacement OK- I was in my groove with Colon Tone so a bit skeptical at first; however, smart of Swanson to add probiotics to the formula. Even tho I take an extra probiotic in the am this one gives a boost to my intestinal tract before bedtime. I am good to go in the morning!

Rated 2 out of 5 by from Still buying but......... I used to take Colon Tone and loved it. Sadly, Swanson's doesn't have it anymore. I switched to this and it works well as long as I keep taking 4 a day! When I switch to the maintenance dose, it doesn't work. It is too expensive to take this way, so I am looking for something else.

Rated 5 out of 5 by from I have used this particular product for 3 years now and have been extremely satisfied with the results. Not harsh at all. What an excellent price!! I would highly recommend it.

Rated 5 out of 5 by from Like it a lot This is a gentle, natural product that I love! It keeps things moving without cramping or other uncomfortable feelings. I like the fact that it is all natural and that it can be taken regularly! I order it all the time!!

Rated 1 out of 5 by from Not worth it I was using Swanton's Colon Tone which was a great product. It was replaced with this one. Terrible! It does not work. Please bring back the Colon Tone!
Date published: 2013-07-30
Rated 4 out of 5 by from Very innovative product I used to buy the Colon Tone and then saw that it was replaced by the Pro-oxy Biotic. I find this is pretty much comparable to the Colon Tone, but with the added probiotics. The only drawback is the large pill size.

Rated 5 out of 5 by from Swanson Ultra Pro-Oxy-Biotic Great product. Easy and convenient, I've noticed a positive difference. I try to eat right but sometimes that's not enough, especially as the years go by.

Rated 5 out of 5 by from A Sleeper Somehow or other this brand has snuck in under the radar without all the hoopla that other probiotics seem to attract. I like it. Of course it doesn't supply the gazillions of organisms that some other brands advertise, but it does contain Magnesium Hydroxide, the very same ingredient well all know and love as the prime mover in Milk of Magnesia. Yes, sleep on it and you'll know whether you made the right choice in the morning.

Rated 5 out of 5 by from best probiotic I have tried I found this to be the best probiotic I have tried. Noticed the difference with this one right away. Have tried several others and they just didn't work as effectively as this one. They may have had more strains, but need to get something more to feel the difference.

Rated 5 out of 5 by from A must have colon cleanser. First time taking this product and am extremely satisfied with result....Happy i made the choice to use Pro-Oxy-Biotic..It did the work like nothing else...Thank u Swanson..

Rated 5 out of 5 by from Noticeable results in only 3 days! I have been searching for a safe, yet effective colon/digestive support product. I have tried MANY things only to be dissatisfied, I figured I might as well try this. I am very impressed with the effectiveness of this product. I am taking as directed and in 3 days have become regular. There was no gastric upset as with other products I've tried. I am back on the site not only to rave about this product but I am stocking up! Thanks Swanson for another great product!
