Renew Life Ultimate Flora RTS Colon Care Probiotic Supplement

Renew Life Ultimate Flora RTS Colon Care is a probiotic supplement containing only Bifidobacterium species. It is marketed for digestive and bowel support. This formula is one of several different formulations of room-temperature stable probiotic supplements by Renew Life. You can learn about the others here.

This product is officially discontinued by the manufacturer as of early 2015 because the Renew Life Ultimate Flora RTS Senior Care probiotic supplement has the same species, but in a stronger formulation. Thanks to Jay for alerting me to the discontinuation.

As shown in the picture to the right, the RTS capsules are sealed in double-foil blister packs to shield the probiotics from moisture and oxygen and prolong their lives at room temperature. During hot weather, however, refrigerating or freezing these products will prolong shelf life.

What are the Pros of Renew Life Ultimate Flora RTS Colon Care?

The pros of this probiotic supplement as I see them are:

  • It contains 6 different Bifidobacterium strains. Although you don't know what strains are in the product, the fact that it is marketed for digestive and bowel (presumably they mean large bowel or colon) health and contains bifido strains makes sense.
  • The vegetable capsule is a delayed-release capsule meaning that the ingredients have some measure of protection from stomach acid so that they can reach the intestines.
  • The other ingredients are minimal.
  • The product is gluten-free and dairy-free and the microbes are grown on a non-gluten carbohydrate base, not a dairy base.
  • The product is room-temperature stable so it is easy to use when traveling.
  • The product is individually double-foil blister-pack sealed to protect each supplement until you are ready to take it.
  • The stated CFU are at the time of expiration as long as the product is kept at room temperature.
  • It has good reviews online:

"I had the misfortune of getting a c-diff infection back in 2009... After much experimenting there is something about these strains in these amounts that keeps my system operating just about perfect again. I've been using these for over a year now and the help they bring has not diminished at all over time. I can not say enough good things about this product."

"I was taking general use probiotics before, then the health store owner recommended the colon care ultra because it provides good bacteria specific to the colon. My stomach problems are much improved now..."

"I have chronic IBS, and this works much better than other probiotics I have tried."

What are the Cons of Renew Life Ultimate Flora RTS Colon Care?

The cons of this supplement as I see them are:

  • You know don't which strains of Bifidobacterium are in the product. Designating B. lactis (A) and (B) doesn't define them either. If you are wanting a particular strain, you have no idea if the one you want is in this product.
  • This product has a total of 15 billion CFU from the 6 strains which may or may not be enough for you. Sometimes it is helpful to start slowly with probiotics, ramp them up and then back down to a maintenance dosage.
  • The GMO status of the product is not known as of this writing; however, Renew Life is in the early stages of trying to verify which of their products are free of GMO's and will make that information available as they find out. They are using a third-party service to determine the non-GMO status.
  • No studies with this product were performed. Note that this is not unusual, however, as very few multi-species probiotic products are used in studies. Usually manufacturers choose species/strains that are shown to be effective and non-competing and those are blended together in most multi-species products such as this Renew Life one.
