Renew Life Ultimate Flora Critical Care 50 Billion

What is it and what is it for?

Canada’s top selling probiotic! Ultimate Flora Critical Care delivers 50 billion beneficial bacteria from 10 strains in each protected capsule. It is the perfect balanced formula to help maintain good digestive and overall health while boosting immunity and easing constipation.

Detailed Description

When nothing else seems to work, Ultimate Flora Critical Care DOES! Ultimate Flora Critical Care’s blend of 50 Billion active cultures from 10 different strains in a ‘once a day’ serving helps ensure a healthy microbacterial environment in the intestinal tract.

The term ‘probiotic’ means supporting life. Probiotics are friendly, beneficial bacteria. These bacteria (as well as others) are normal inhabitants of the large and small intestines and are a very important part of a healthy digestive system. There are over 500 types of bacteria in the digestive system; the two most prevalent are Lactobacilli and Bifidobacterium. Bifidobacterium are the most prevalent bacteria in the large intestine and Lactobacilli are the most prevalent in the small intestine.

Ultimate Flora Critical Care contains therapeutic levels of both Lactobacilli and Bifidobacterium, making it the most complete and effective probiotic supplement on the market. Each capsule provides 50 Billion active cultures from 10 different strains in a ‘once a day’ serving (30 billion active cultures of Bifidobacterium and 20 billion active cultures of Lactobacilli and Lactococcus). Ultimate Flora Critical Care also contains FOS (fructooligosaccharides), which is an optimal food source for probiotics. FOS aids in the colonization of probiotics in the intestinal tract.

Ultimate Flora Critical Care uses a unique, water based enteric coating that protects the probiotics against being destroyed in the acidic environment of the stomach, yet still allows for the probiotics to populate in the intestinal tract. Ultimate Flora Critical Care contains no starches, fillers, or excipients – making it the cleanest product available.

Ultimate Flora critical Care is formulated for those who:

  • want a high potency daily use probiotic
  • are using or have recently used antibiotics
  • have chronic digestive issues
  • want to boost their immune system

Renew Life Ultimate Flora Critical Care 50 Billion FAQ

What is Ultimate Flora Critical Care?

Ultimate Flora Critical Care is a 50 billion culture, 10 strain probiotic formula designed for those who have chronic digestive issues, those who want to boost their immune systems and those who are using or have recently used antibiotics.

How is it delivered?

Ultimate Flora Critical Care includes 10 strains of powdered probiotics which are contained in vegetable capsules. The capsules are sprayed with a unique, water-
based enteric coating. This coating protects the probiotics from the acidic environment in the stomach, yet still allows them to populate in the intestinal tract.

What does it do?

Ultimate Flora Critical Care’s blend of 10 beneficial bacteria help ensure a healthy microbacterial environment in the intestinal tract.

The term ‘probiotic’ means supporting life. Probiotics are friendly, beneficial bacteria. These bacteria (as well as others) are normal inhabitants of the large and small intestines. Probiotics are a very important part of a healthy digestive system. Recent research shows that probiotics help improve gastrointestinal functions, respiratory and allergy responses, as well as help to counter the negative effects of antibiotic use. Probiotics support the immune system, balance the intestinal environment and inhibit the growth of pathogenic organisms (ex. Candida albacans). Further, these beneficial bacteria help the body to 1) produce vitamins, 2) digest foods, and 3) control overgrowth of bad bacteria and fungus.

How does it work?

There are over 500 different types of bacteria in the digestive system; the two most prevalent are Lactobacilli and Bifidobacterium. Bifidobacterium are the most prevalent bacteria in the large intestine, while Lactobacilli are the most prevalent in the small intestine. As we age, studies show that our levels of Bifidobacterium decline, while harmful pathogenic bacteria increase. This is one of the main reasons that intestinal ailments increase as we age.

Ultimate Flora Critical Care contains therapeutic levels of both Lactobacilli and Bifidobacterium, making it the most complete and effective probiotic supplement on the market. Each capsule provides 30 billion active cultures of Bifidobacterium and 20 billion active cultures of Lactobacilli and Lactococcus.

Ultimate Flora Critical Care is the only encapsulated probiotic formula that can guarantee significant quantities of the probiotics contained will survive past the harsh, acidic environment of the stomach and arrive alive in the intestinal tract. Using a unique, water based enteric coating, we ensure that the probiotics are protected, yet still able to populate in the intestinal tract.

What can I expect?

Ultimate Flora Critical Care is a therapeutic strength, multi strain probiotic supplement formulated for chronic digestive issues. As such, you can expect to see a reduction in symptoms over weeks of use. Ultimate Flora may be used alongside other Renew Life products to treat the problem more thoroughly.

Once your chronic condition is under control, you may wish to switch from Ultimate Flora Critical Care, to our FloraSMART or FloraSMART Extra Strength product which can be used daily for maintenance.


A better day for me!

Ultimate flora has helped reduce the bloating and discomfort I used to feel all day long. For me, that means less fatigue and a happier mood. I no longer dread how I will feel after eating and having more energy equals a better day for me!

– Lisa A., Manitoba

Thank you very much for a fantastic product and for all you are doing.

Just a quick note to say how helpful your Ultimate Flora 50b product was for me. I had ongoing discomfort for 4 days after a bout of food poisoning and after just 1 capsule I had immense relief. After 2 days I felt back to normal.

– Michael Z.

Great product!

I started using Renew Life Critical Care after being diagnosed with Ulcerative Colitis. A friend of mine recommended them and I was amazed at what a difference they made! I have stopped taking most of my medication and have managed to stay flare-free for about 2 months now. I would definitely recommend the product. It’s only downsides are that it isn’t covered by my current benefit plan and they are a little pricey. Regardless, I would definitely recommend Renew Life Critical Care Probiotics to anybody who suffers from IBD. It made a huge difference for me.

– Mary Anne, Sault Ste. Marie

You will be amazed at the level of health you can get to.

I haven’t found found a probiotic that has worked better for me than your critical care probiotic. I have been taking several different probiotics in the past 3 years and can say based on experience that this is by far the best probiotic for people with severe digestion problems.

I won’t go in to detail about how bad my situation has been but I can safely say that if my situation can be improved or possibly cured (I have hope now) than anyone’s can be.

I have this product combined with Molkosan to thank for that. No other probiotic made such a noticeable, life changing difference. Combined with Molkosan (these two products seem to love each other), a healthy diet, proper sleep and some exercise, you will see improvements like you never have before.

Don’t expect to go from bed ridden to Olympic champ overnight but you will see noticeable improvements within a few days and if you stick with it even after your feeling a lot better, approx 3 months or more you will be amazed at the level of health you can get to.

– Ken O.

Great products!

Six years ago I went through six months of very intense chemo. It left me with a very weak immune system and I found it hard to even think straight. I just felt very worn out.

A friend suggested that I try the Renew Life Super Critical Omega which contains Vitamin D. I also had thinning bones. My bone density today is stable, if I get sick which isn’t often, I don’t get real sick and I get better fast. My thinking is clear and my joints don’t hurt. I feel really good. I’m also eating a very healthy diet along with the omegas. I highly recommend this product to anyone who is feeling the way I felt or if you just like feeling healthy. It doesn’t smell when you open the jar and if you do burp there is just a pleasant orange taste.

I’m also taking the Ultimate Flora which has been a tremendous help. My bowels were not functioning properly and as soon I took this product within days I was normal. I also highly recommend this product.

– Wendy A., Toronto, ON

The best I've tried

I have tried a couple other brands of probiotics while on antibiotics, and this is the best by far. It’s so important to have a good probiotic while taking antibiotics. Your body will thank you!

– Maria W.

Thank you for giving me my life back!

My name is Bev and I belong to a website called IHAVEUC.COM. It is a website where people with ulcerative colitis can ask questions, relate their stories, as well as help and support each other.

I live in Penticton B.C. and I have had ulcerative colitis for almost 20 years. The majority of that time I was on presciption medication which really never helped me and quite frankly, made me feel even sicker. I decided to try probiotics after reading up on them on the good old internet. Not expecting them to really work, I went into my local vitamin store and was recommended ULTIMATE FLORA CRITICAL CARE by RENEWLIFE. Well, your product has quite literally saved my lfe to the point where for almost a full year, I am symptom free…and here’s the kicker…without any prescription meds at all! I have been taking them for almost a year, faithfully every day, and will continue to do so forever.

Anyway, because they worked so well for myself, I felt that I should share this with everyone on the IHAVEUC website. So many people on the websitehave tried my suggestion, are trying it, and are going to try it!! Testemonials have come back full of gratitude and happiness, to me! It is not me though…it is your wonderful product! It makes me want to cry (I actually do cry at times) with joy to hear that others are healing just like I have!

I was so sick for the last 15 years. 15 years of my life that I cannot get back. I dread that other people will go through what I have. However, they are and they do. Dangerous medications. One after another, as each one stops working. It’s no way to live a life. Ulcerative colitis is an awful disease that robs you of your life. The word needs to get out that probiotics can actually heal this condition, whereas the drugs are just a band-aid that mask the problem, and each one eventually stops working. Do you know how many people have opted for colon removal because they just can’t live that way any more? I almost did, when the specialist recommended that after one drug was no longer ‘working’ that I then take remicade and imuran…two immune suppressors! I am so relieved that I declined and tried YOUR PROBIOTICS!!

I just had to tell you this. If someone in your organization can, they should join and read and even offer advice on the IHAVEUC.COM website. There are alot of us who already believe in the power of your product…but plenty of new people join the site every day…sadly…scared at their diagnoses. It seems to be an epidemic, probably stemming from the overuse of antibiotics and other prescription drugs, like accutane. People ask me over and over on there what probiotic I am taking that has given me such great results, that has given me my life back…and I tell them over and over again…ULTIMATE FLORA CRITICAL CARE by RENEWLIFE!! You should be seeing a jump in sales…lol!! Everyone who has a bowel problem or so called ‘disease’ should be on them!! Even people who are normal! Prevention…

Thank you for giving me my life back.

Sincerely and gratefully,

– Bev C.

Saved me!

I take Intestinal Bowel Support along with Renew Life Ultimate Flora Probiotic. Together they have helped my IBS immensely! Within the first 2 days of taking them, my symptoms had drastically improved. My only complaint is that they are quite expensive. It was $28 for the bowel support (2 week supply) and $57 for the probiotic. (2 month supply). Regardless, they work so they are definitely worth it!

– Katherine


I am 21 years old and I had been ingesting sucralose (“splenda”: a chlorine made artificial sweetener) for about 6 months in large doses (it was in 75% of the food I was eating daily) because I got a uti and was trying to avoid sugar. I began having terrible diarrhia, vomiting, gas, insomnia, major indigestion, constantly having to use the washroom and major health break down.

After I figured out what was causing all this, I cut off the splenda and did a several month long cleanse. Some of my major issues had gotten better but for the next year I still had major gas (flautulence) and heartburn after every meal no matter what I ate and I also still had sleep troubles about 75% of my sleeps.

I thought that the splenda had done irreversable damage to my body and I would have embarrasing gas for the rest of my life. Finally I did some research on probiotics and figured that what was wrong with my body and immune system was most likely that the probiotic communities had been destroyed (by ingesting chlorine sugar in large amounts). So I was looking for a good probiotic and stumbled upon Ultimate Flora Critical Care.

I have been using it for 2 months, I have also done the candigone cleanse, I have used the candizyme (15 days) and have cleaned up my diet (even though it was already pretty good). I am ecstatic! No more embarrasing gassiness, sleep is much better, no more brain fogginess, better mood, more energy. I finally feel like I should, a 21 year old in his prime. I am so greatful for this product; it has given me my livelihood back. I will keep using it and can’t wait to continue to see my health improve.

Thank you Renew Life!

I was diagnosed with late stage Lyme tick disease in Aug 2011. Immediately I was put on a long term regimen of very high doses of Antibiotics. 8 days later the herxing began – dumping of all bacteria in my body. I suffered for 2 days, passing blood, and feeling like I swallowed a handful of razor blades. Reading somewhere that this was normal I tried to let it pass. On the evening of the third day I called my specialist who said, I was experiencing C-diff bacteria and I needed to increase the good bacteria to kill it off. He said eat curds, yogurt, cheese, ice cream milk and take acidophilus. I went directly to my health shop and was offered 3 choices of acidophilus. I bought the strongest I could get – ultimate flora.

I came home ate a bag of curds and a quart of yogurt and took two capsules. Later that night I took another 2 capsules. Within 48 hours I was back to relative normal. JUST AMAZED!!!! I continued taking a capsule a day and recovery was faster than expected. I believe if you give your body the tools it will heal itself.

Three months later they switch my antibiotics – 6 days into the treatment my guts turn upside down again. I go to the fridge and realize I had bought a different brand in month 2 and went right out to buy a new bottle of ultimate flora, some curds and yogurt. Within 24 hours I was back to normal. The next day I happened to be watching a PBS program by Brenda and was amazed how what she was saying was exactly what I was experiencing. She then went on to say about what to look for in a product that works. I immediately went to the fridge to grab the bottle I was using only to find out it WAS the same. I placed a capsule of ultimate flora in a glass of milk as well as a capsule of the other brand in another glass of milk. Next morning ultimate flora showed results and the other brand looked the same.

As I recover I am rallying everyone especially with Lyme disease to take this product. It is the ultimate tool to help your body fight bacteria.

My symptoms have taken a 180, I no longer have asthma, no heart attack symptoms, no need for cataract surgery in my right eye, jumping joint pain is gone, night sweats are none existent, brain is less blurry and memory is getting stronger. I completed the Las Vegas Rock and Roll half marathon on Sunday with NO puffer!!!!

The burgdorferi bacteria was killing me and my good bacteria did not have a chance against it. With the antibiotic treatment and ultimate flora I am on the road to GREAT health.

I have a strong suspicion that more and more strains of bad bacteria are going to be identified as the reason for many illnesses and it will be imperative to give our bodies the RIGHT tools to fight.

I can’t say enough about how amazing these probiotics are! I used to have constant digestive issues and constipation and Ultimate Flora cleared it all up. I HIGHLY recommend it!

– Kelly

Wow, it really helped!

I got really sick with Cholera and E-Coli after I went to Africa last year. When I got back I had really loose stools and couldn’t even leave the house. I took your Ultimate Flora Critical Care and Organic Clear Fibre and I can’t believe how much it helped. The fibre really helped to bulk things up so that I was not rushing to the washroom all the time. I could add it to anything and it didn’t taste at all which was great because I was adding it to everything :) The Ultimate Flora was incredible too, it really helped to balance things in my gut and I was back on track in no time. Thank you sooooo much for amazing products!

– Carol P.

I Salute Your Fine Product

Having taken upwards of 20 million units of penicillin daily for a period of time and regularly taking 4000 units daily since January 2010, I credit your probiotic with helping me avoid all the damage that this huge amount of antibiotic could have done to my system. Thank you!

– Barbara S.

Thank You For Saving My Life

Hi. I have to tell you a short story… I am a person who has worked in the field of Pharmaceuticals and cosmetics for years. I went into another area of work and formed my own company Red Velvet Media. One of my clients/friends is Food4africa… well I was gone for 9 months in Africa and all over the area helping… I came home and started to have problem’s with my stomach.

I have always been 105 pounds and able to eat anything… well of all things after years of the doctors not knowing what was wrong they told me I had h-Pylori :( Of all things I get the one thing I used to talk to Dr’s about when working with Priolsec. Funny, I went to the local health food store and told them I had just done a horrible treatment for 2 weeks of intense antibiotic’s and felt like I was drained and was not able to eat or feel comfortable.

I was turned on to your Ultimate Flora Critical Care 50 billion probiotic. I had never taken a probiotic before and I was all for the natural thing after I felt so drained from all the antibiotic’s and stuff they gave me for two weeks straight. I felt like I was going to die, it hurt and made my life pretty much a stay at home for those two weeks. I was sick and in the bathroom almost the entire time. Your product saved my life and brought me back to life. I started taking it and then was able to start life again… I am young and in a Samurai sword class that I was missing from being so ill to my stomach.

I now take Ultimate Flora every day along with a probiotic drink and I have never felt better. I want to thank you again for such an amazing product. I now have no problem with foods or feeling pain or sick to my stomach any more.

Thank you again for saving my life and bringing back the quality of life I have always had.

– Holly S.

It worked after ONE day!

I have struggled with irregularity in bowel function, yeast infections, embarrassing halitosis, lactose intolerance, food allergies, Irritable Bowel Syndrome, and more recently excessive gas and bloating. Digestive pain after eating was normal for me since I was a child and so I was always underweight and allergic to things it seemed everyone else could eat. I took a lot of antibiotics for tonsillitis during childhood and when I got my wisdom teeth out, the powerful antibiotic I took was the last straw. I have been taking acidophilus pills and enzymes daily with food along with straight vinegar when indigestion would hit. I saw little improvement.

After one DAY on Ultimate Flora Critical Care 50, I could feel a difference in my body function. It began to clean my colon within hours, not days. I have never felt like I had a “normal” bowel movement, they were meager and only every 2 or 3 days. On my first day, I had two with no bleeding fissures or discharge due to trauma. Only a person who has been through what I have could understand the happiness that brought me no matter how private that seems. Later that day, while walking my dog, I felt the urge to run, I had energy instead of feeling toxic and lethargic. I ran a mile. That is why I just had to write and tell you of my experience and I hope ANYONE who has had digestive problems and the side effects they cause will find and use your products.

I am 46 and have dealt with allergy symptoms for most of my adult life and at times the symptoms would be so severe that I couldn’t carry on ‘normally’.

About 11 yrs. ago I was diagnosed with asthma, which is just an allergic symptom in the lungs, and was prescribed inhalers, one being a steroid (Pulmicort). I found, to my astonishment, that one time I needed to use 8 puffs a day of the steroid inhaler for about a week, I got severe laryngitis, which needless to say, didn’t impress me.

An overactive immune response (asthma) also ups mucous production, so I was always doing a lot of coughing because my body wanted to get the mucous out and also because of the wheezing and tightness.

I recently discovered that about 80% of the immune system resides in the ‘gut’ and that an imbalance of the good/bad bacteria can affect immune response. I then thought about the fact that over the years I had been on antibiotics many times and was not informed by any doctor that they not only kill the bad bacteria, but also the good. So I thought to myself that my ‘gut’ was probably not in good shape.

I decided to buy ULTIMATE FLORA and I am so glad I did. I can not begin to tell you how great I feel. After I starting taking the product I immediately noticed an improvement in all my allergic symptoms, most of all, the asthma. I have not had to use ANY inhalers for the past week and I am looking forward to hopefully many more weeks with NO inhalers. Research/knowledge gives one power and choices.

I thank RENEW LIFE for a quality product that has changed my health for the better.

– Kathryn K.

Thank you Renew Life!

I wanted to share my experience with taking Intestinew Powder and Critical Care Ultimate Flora. I work at Nutrition House and was recently diagnosed with Collagenous Colitis, which is a rare type of colitis. I seem to have a flare up every six weeks, which lasts for six weeks. I get terrible cramps, bloating and watery diarrhea. I have tried everything on the market and have not had great results.

About a month ago we had a training dinner with Marti, my Account Manager for Renew Life and she suggested I try Intestinew and Ultimate Flora, which I did. I have been taking them for two weeks and within one week I was feeling better, the bloating and cramping have subsided and the painful inflammation has also cleared up. I still get a bit of diarrhea, but nothing like before.

I have a trip planned to Mexico at the end of November with 6 of my girlfriends, and I was afraid of how I was going to manage down there, but now I am happy to say I am looking forward to having a great time. Thank you Marti and Renew Life. You can be sure I will be recommending Renew Life products to all my customers.

– Norma Y.

Thank you very much for the Ultimate Flora

Thanks to your products and advice, I am now feeling almost completely recovered from C-difficile. Two weeks ago I was very worried about my long-term recovery prospects and disappointed by the lack of progress, since then I have religiously taken Ultimate Flora Critical Care capsules every day. I believe I am now living proof that your probiotics can overcome c-diff. I will stay the course for at least two more weeks at current dosage levels and then gradually taper to a more normal daily dose. I now confidently expect to be c-diff free by then.

Thank you very much!

– R.B.
