Great product!

My self, my husband and 1 teenage son have been taking this product for about 3 years now. I was looking for a product with a high enough good bacteria count that wasn't digested in the stomach and this was it. Although maybe expensive, compared to other products on the market, I feel it's a great deal especially since it helps us to be healthier. I would have given it 5 stars except in most bottles a pill or 2 are empty or damaged by production errors. I hope they improve their quality inspection, the product is otherwise worth it.

Life ReNewing 5 Stars

At age 48, I have experienced issues with my gut, digestive track all my life. I have survived 12 operations colon rectal. Thankfully, Cancer was not detected. 12 yrs surgery free, and yet have I ever in my adult life known what feeling good is? 2012-2013 I went Gluten Free in my diet, no cheating. As I was willing to try anything to " feel better". I came away realizing, yes, I am wheat sensitive, I am however not gluten intolerant. I gained weight within going Gluten free, my learning, this diet made me feel worse not better. Broke too, to add, as going Gluten Free is costly.

Present day, I am a New Person. I've been taking ReNew Probiotics on and off for a few years for digestive disruptions. The Critical Colon Care 80 to put me back together. I wasn't however taking them daily.

In July 2014, I began taking daily what I had in my fridge, the remaining Critical Colon Care 80, then I finished off what was left of my ReNew 50 Billion Critical Care. In one weeks time I could feel all positive reactions being stimulated in my body. I continued with the 50 Billion, buying another bottle. I finished the 30 count. I went back to the 80 Billion, days ago.

Since July 20, 2014, to present day November 14, 2014, I have lost 20lbs, literally the weight has fallen off. I no longer have cravings of endless eating, my body feeling starved. My appetite has balance. I no longer experience " sugar crashes". My bowels are no longer controlling me. I am finally for once in control of my body. I have " Energy" that I have not felt since my early 20's. My experience is now I know that my gut was a literal war zone, that it was so unhealthy it affected my entire being. No Longer am I at war. I am healing and rebuilding from the inside out.

Another example: Today viewing my fingernails. My right hand pointer finger " nail" was severely damaged when I was 5 yrs old. The injury to create a permanent white stripe, and separation of the tip of my nail. The nail to grow " split" for my entire life it's been deformed.

Since taking " daily" the ReNew Probiotics, I noticed today, my finger nail has repaired itself. The stripe is gone, the nail is not split at the top. My color of my nail bed, Pink and healthy instead of foggy white. Right there is testimony of, I thought a never possible.

I ran out of my pills and was without them for 4 days, and MAN did I feel it, I felt off.
It's for what I need, my body is so reciprocating, and it's only been since July.
I have seen persons recently who have not seen me in a few months. They are " WOW"
did you find the Fountain of YOUTH? answer: Yes, ReNew Probiotics. I refer them to EVERYONE.

I feel like a Teenager. I know now how it feels " to Feel great" Thank you, Thank you.
Anyone who is about to give up, DON'T. I cannot say enough of the positive results, Life Saving, is yes, ReNew Probiotics.

True probiotic value

It's very difficult to separate the hype from the true value with a product like this. I didn't want to waste my money on a poor probiotic, so I did a fair amount of research beforehand. My first filter was built on the assumption that a quality product would not need to resort to pitchman hype to sell their product, therefore I eliminated any product which seemed to be marketed in that way. Secondly, manufacturer claims are difficult to weigh, therefore I focused on consumer reviews, which appeared to be compiled in a fair and unfiltered way.

I gambled on this product, buying it from a store which kept it refrigerated. I understand that high temperatures only reduce the percentage of live bacteria, and don't kill it outright, however, I wouldn't want to have this product shipped direct, because there's no telling whether it was sitting in the back of a hot truck over a weekend or not.

It seems to work quite well, restoring my stomach to what feels like normal operation, after a bout of antibiotic treatment, which tended to leave my digestive tract fairly sterile. I would recommend this product, based on my own experience, and the many positive reviews it has received.

Reviewed by GregP507 on 10/28/13


Does this product need to be refrigerated? I am confused about when to take it. On the bottle it says 2 hours after a meal. On this website it says to take with a meal?? Thank you.

MODERATOR NOTE: The product doesn't HAVE to be refrigerated to maintain potency, but it is a good way to keep unwanted moisture out of the pills.

I feel great.

The doctor prescribed Omeprazole for a bleeding ulcer. I took it for a couple months, then I told the doctor, I refuse to take it any longer because it upset my bowel pattern. I had loose stools frequently.

He wanted to do a colonoscopy again. The doctor asked me to list the time of day or night I had a bowel movement. I had trouble making the trip from my bed to the bathroom, and had to wish out my clothes because I didn't make it.

After taking the test, I had diarrhea 27 times a day. It went 24\7 and I could not go to church or visit other people, I had to stop volunteering at the Hospital (I was a snuggler of the babies in the heart unit) where I had been doing it for 13 years - ever since I retired. I love doing the volunteer work, and it broke my heart that I could not do it any more.
A friend told me I should take some probiotics from the health foods store. So I went to the health food store and the expert there told me that this Ultimate Flora is what I should take daily - even if I was not having runny stools. This was GOOD bacteria and our bodies needed this daily.
I took this twice a day for a week. That did it, the times I went to the bathroom moved from 27 x a day down to 4 times a day. I felt so much better. I felt good. The doctors took every test available to try to find out what was wrong. All test came out negative. If nothing was wrong, why was I so sick and going to the bathroom so often? They had no answer and gave no direction as what to do. Thanks to the health food store and Ultimate Flora Critical Care Probiotic, I feel great. Thank you so very much. I tell everyone that ask me about Probiotics, it works for me.

first of all i would like to thank you for a superior product that i believe has changed my life!!
here is my story;
11 months ago i was diagnosed in the e.r. with divurticulitis of the upper colon, of which i was told by 3 doctors was a rare spot to have it. i was hospitalized for 3 days on only a sugar/saline and antibiotics i.v.'s and could not even drink water or have ice chips. 2 days after being released i stumbled upon brenda watson on pbs and the 2 hour show about probiotics. i had also been suffering from chronic hives off and on for about 2 years which also sent me to the e.r. a year earlier!! i also have other autoimmune issues of hypothyroid and vitiligo.
everything that brenda was talking about made so much sense. i never realized that most of my issues could be caused by gut problems!
since that day in the hospital and upon taking the ultimate flora 50 billion each day my hives have never returned and after having a colonoscopy/endoscopy, 3 months ago, the results showed absolutely no divurticulosis or anything at all!!
I truly believe this is the result of your product as well as a paleo type anti-inflammatory diet. i have been referring friends to your site to start taking probiotics!!

Great product

My daughter, who is 14, stated having skin problems. The sores hurt and itched her. I did not know what to do so I brought her to a dermatologist. He also could not figure out why she was breaking out. He ran blood work, did a skin biopsy and still no answers. So after all the tests he says there is anew thing that we could try. He tells me she would have to have blood work drawn every month to check her liver. I right away was thinking no. Then he told me what he wanted to put her on I was absolutely no! He wanted to put her on a very low dose of chemo.
She would not have lost her hair or got sick. But to worry about her liver, I refused!! I, then frustrated and feeling helpless, turned to my local city market co-op. I asked them what could help my daughters skin? They explained how bacteria starts within our bodies and coume out through our skin. And they recommended Ultimate flora. My daughter was so ready to try something. Within a week her skin improved. We absolutely love this product!! It helped my daughter regain her self confidence!! I want to thank you for having such a great product!! Thank you.
