Ultimate Flora Critical Care

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!

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

Renew Life carries a number of different probiotic formulas. To verify if Ultimate Flora Critical Care is the best formulation for your condition, please view our probiotic comparison chart.

What is Ultimate Flora Critical Care?

Ultimate Flora Critical Care is a 50 billion culture, 10 strain probiotic formula.

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.

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.

  1. Asthma/Allergies
    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...Continue Reading 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.

  2. 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...Continue Reading 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.

  3. 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...Continue Reading 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!
