IntestiNEW is an L-glutamine and N-acetyl D-glucosamine supplement with additional soothing herbs to support the integrity and healthy function of the intestinal lining.ǂ It also includes gamma oryzanol—an extract of rice bran oil, which has been shown to have antioxidant effects in the digestive tract.ǂ IntestiNEW is gluten free, and is free of fillers and binders. It is available in powder or capsules.

What is the Intestinal Lining?
The mucosa, or lining, of the digestive tract spans all the way from the esophagus to the colon. It serves as a place for food breakdown and nutrient absorption to take place. This delicate lining is semipermeable; ideally, this membrane allows nutrients into the bloodstream and keeps toxins, pathogens, and undigested food out. 

The Importance of a Healthy Intestinal Lining
The intestinal lining serves many functions. Three of the most critical are:
1) Helps to continue the digestion process after the food you consumed leaves the stomach.
2) Assists with the absorption of nutrients from food; this part of the digestion process occurs in the small intestine after food leaves the stomach.
3) Protects the body from unwanted digestive contents entering the bloodstream.

The intestinal lining is like the skin, in that it sloughs off a layer of cells naturally every 3-5 days and produces new cells to keep the lining semipermeable. To keep new cells continually growing, the amino acid L-glutamine is the primary fuel for this process.ǂ When functioning properly, the body converts L-glutamine into N-acetyl D-glucosamine, an amino sugar found in all tissues of the body. Much of the intestinal lining is composed of N-acetyl D-glucosamine, which helps hold the cells of the intestinal lining together.ǂ

  • Naturopath was impressed  |  (Posted on 9/13/14)

    Review by Nicole

    Out of 5

    I have been working with my naturopath to heal leaky gut, dysbiosis, candida, parasites, and some other things. I have been using several Renew Life supplements to help with these. When I brought in my supplements so the Naturopath could look at them and test the effectiveness of them (with applied kinesiology) she was impressed with IntestiNew. She said that the paragone and candigone cleanse was much more effective with the IntestiNew. She also had never seen a supplement with such high amounts of L-Glutamine before. The supplement she sells only had 50 mg i believe (quite the different). I am can not, however, testify to the effectiveness of this supplement as I have many complex problems I am treating with tons of supplements constantly changing. I can not isolate it to the IntestiNew to say how it has worked for me.

    The powder is pretty mild tasting. It is gritty and slightly sweet (due to the stevia leaf added). It does not dissolve well in water so I always put it in my nutribullet and give it a quick blend so i can drink it without clumps.

  • Threw out the Prilosec!  |  (Posted on 8/5/14)

    Review by Melinda

    Out of 5

    IntestiNew made me feel young again! At first I popped two between each meal to calm the volcano in my gut. Now I only need maybe 2 during the day or sometimes I'll take one between meals, depending.
    A year of misery with stomach pain and bloating had been rapidly aging me. I had lost 40 pounds, could find little to eat that didn't upset me, activities and social life bottomed out. Severe gastric problems stemming from an antibiotic reaction sent me to the ER. At 64 years, I'd long ago decided alcohol and fast food was bad while eating healthy and taking nutritional supplements was what kept me out of the doctor's office. But one wrong call by my dentist with medicine I didn't really need threw all my good work out the window and I thought death was at the door. At the ER they said GERD plus an ulcer and gave me Prilosec, a pill to counteract the side effects of Prilosec and an antidepressant to counter them both (the last one I refused). After a week on drugs, things seemed worse so I turned back to natural solutions. The health food store gal turned me onto RenewLife probiotics which were a great start. (I had always thought my daily Activia yogurt was enough and my druggist told me to AVOID probiotics, go figure).
    After I discovered how easy it is to order directly from RenewLife and get discounts with fast free shipping, I've been able to afford trying several of the products that weren't at the health store. And I was getting better! But I wanted mo' better and added IntestiNew to my routine. Eureka! Now I can go out to eat like a normal person without making my companions uncomfortable while I search for something on the menu that won't hurt me. Those days are in the rearview, although things like pizza or store bought cookies still make my gut talk out in warning. It is still important to eat the right things and drink LOTS of good water. I could write pages on how much I love IntestiNew and will always have no less than a half bottle on hand at all times. I noticed one reviewer said the capsules caused her constipation. Everyone's different of course but when my bowels began to heal, formerly loose stools started trending to constipation. At that time I added CleanseMore, upped my water intake and went to normal doses of IntestiNew. I feel better than I have in years, even before my gastric crash.

    I have IBS and I had it come back after eating pizza. I found "IntestiNew" in the health food store and started it in the car right away. I love this product, it works so well. I have been on it for about two weeks and I feel so much better, thank you so much. I never will be without it. Just knowing that if this happens again I can do something for it without side affects and peace of mind. Than you again, not only for the product but for being so kind to me when I called.

    After rushing to the E.R. with a terrible stomach pain; I was prescribe Prilosec for my diagnosed stomach ulcer. I immediately ran to the health food store to find some natural help for an ulcer. It was recommend that I try IntestiNEW (powered one). Within a week the pain was gone. I finished the first container and repeated therapy with another container. During this time I received an endoscopy and everything looked good. My doctor thinks it is due to the Prilosec (that I did not take). Now I maintain my stomach lining with DGL Chewable Licorice and have been pain free. I truly recommend this product to any one who is suffering with stomach ulcers.

    Review by Sheila

    For the past 11 years I have been researching vitamins, articles and cook books to deal with my food allergies. It all began when I started telling the doctors, and the nutritionist at All Ways Health in Lake Zurich, IL, "I am not digesting my life". That statement was true. Through trial and error I also discovered I could no longer digest gluten, corn, soy or vinegar. I have always been allergic to milk and I am very careful not to eat foods with a high sugar content.

    I used CleanseSmart with great success. However, the belly bloating and brain fogginess would return within a week after I had completed the cleanse. I was discouraged until I spoke with a Renew Life representative. She patiently listened to my story and suggested I use IntestiNew. Within a few days I felt like I had found a winning lotto ticket or a buried treasure chest! For the past 2 months I have used IntestiNew each morning. The belly bloating and brain fogginess have not returned. y energy, alterness, focus and comfort have returned to "my normal levels". Bravo to Renew Life and your IntestiNew product for helping me! Every day I am most grateful for my blessings of good health!

    Wanting to get off the PPI's that I have taken for 15 years to help with GERD, my local health food store recommended I try the IntestiNew. My attempts in the past to stop taking the PPI all met in failure, but not this time! I have seen a drastic change in how I feel, the comfort level is the same as if I were still taking the PPI. The unexpected change to the daily urgent trips to the bathroom due to Crohn's has greatly diminished and I feel I'm getting my life back outside the bathroom. This has been truly AMAZING! Thank you, Brenda.

    Review by Gastritis errr

    Out of 5

    I was pregnant recently & had gastritis before I got pregnant. The pain in the pit of your gut is so unbearable. I was in misery. I didn't want to talk, eat, nothing. Unfortunalty, I lost the pregnance due to this and it hurts, I'm healing my gastritis today with DGL, probiotics, and multiviatmins, and I do not eat anything pass 5pm. ONLY water, my stomach has improved, I stopped taking all Priolsec, tums, etc. almost 4 mos ago, the Drs won't tell you about the natural stuff your body needs to heal, they just want to keep you medicated & coming back for more $$$ I did an intensive research which lead me to this page & this site. I WILL ORDER THIS PRODUCT TODAY & I PROMISE TO GIVE AN UPDATE ON MY SITUATION. I would go the ER sooo many times, (due to gastritis pains) my insurance company wrote me a very nice long letter about it, the ER drs knew me by name and all. It was crazy. But I decided to take matters into my own hands. Trust me.. if u have stomach issues, stop drinking coffee, soda and stick to water. I know its hard at first, but your body is in need of it.. You want to live!!!! just keep telling yourself that. Believe in GOD beleive in healing!!!! thank you for reading..

    I have Crohns now,11yrs nothing has helped. I have 18mo. old son and feared I would not live long enough to see him growup. My Doctor only pushed (pharm.meds) that gave me horrible side effects, and wanted me to start takeing a medication that would modifiy, and lower my Bloodcell count, and may cause cancer. I refused to take this medication . I had decieded that I would fight the crohns without any more (pharm.Meds.) and with all my will and hope, and pray that I would live long enough to see my son growup. Then I heard about IntestiNEW from an young man that works at a local health food store.(May GOD BLESS HIM!) I got it, and took it rightaway. I could feel results just hours after taking it! The last time I felt this good was 11yrs ago before I had cronhs, and started taking (PHARM.MEDS). This supplement is a true blessing. I have much more hope and faith now! I am so very happy to actually have somthing that will help me and not HURT ME with very BAD SIDE EFFECTS! GOD BLESS your company for making this wonderful supplement.

    I have been suffering with stomach issues well over 2 decades! I've been diagnosed with IBS-D to C-Diff- you name it and I had it! Also, being active duty military, I served overseas a lot and always feared parasites! Long story short, I was crippled by these "stomach disorders!" I could never understand why I could not gain weight or hold food down- I would eat and literally go to the bathroom (sometimes >10x's a day). After years of not having answers, seeing different doctors, long hospital stays, uncomfortable test, medications that I feared more than my issues at hand, and me trying to figure it all out; what I ate that day, what I may have done different- then I thought maybe it's all psychosomatic but, I undoubtedly had abdominal pain, severe diarrhea, bloating, and the sudden urge to use the restroom after every meal or no meal! I FINALLY needed to take charge! I was not going to embracing this nor would I want too! I lived half my life on the toilet--I went to my local "Make it Natural" store and was introduced to Renew products! I started my regimen: I did the 200 Billion 7 day packages first, moved unto the 80 Billion Critical colon, started the IntestNew every morning with my present probiotic the 50 billion critical care and the fish oils with a meal and WOW! Do I feel like a CHAMP-- a person who has a normal BM once or maybe twice a day without that sudden urge of having to run for a RR. And the best part is that I can eat everything! I did change my diet to a much more healthy venue (organics/ herbs/ more seafood) and feel amazing! I can not Thank this company enough for MY LIFE BACK! You don't believe me ask my husband. He suffered as much as I did these past years... As he no longer has to rush me to the nearest rest stop or wait for me to get off the pot! Life is good :-) Sincerely Blessed!!!

    Review by Levan

    On and off, I've been suffering from disbiosis for 12 years. During this period, I took different medicines, but with not much result. Several months ago, I started taking Renew Life's products, namely Cleanse More, Ultimate Flora Critical Care 50 Billion, Ultimate Flora Critical Colon 80 Billion, FiberSmart, IntestiNew and FishSmart Ultra. Amazingly, since then my health changed drastically. In the past, I sometimes would go without a bowel movement for 2 weeks, but now, since I discovered Renew Life, I have a bowel movement every single day.
    Also, during the illness, the growth of my fingernails decreased, but now it's back to normal.
    Thanks to the wonderful products of Renew Life, I feel that I'm on the right track on the road to full recovery.

I had been suffering with terrible cramping and everything else that goes with an attack for almost 8 hours. The IntestiNew took care of every symptom in less than an hour! Thank you for introducing me to this product. I will start carrying it in my store and recommending it to clients. Thanks again!

    The intestiNew powder and DigestMore digestive enzymes have completely improved my quality of life. I've suffered from reflux and esophagitis for years, and have been told by doctors to simply continue taking over-the-counter acid blockers and proton pump inhibitors. I continued to take them but still experienced significant ongoing heartburn and reflux, despite making multiple dietary changes along with taking the medication. After reading about long-term negative side-effects from proton pump inhibitors, I decided to try ReNew's IntestiNew powder to help heal the damage to the lining of my esophagus and DigestMore enzymes for the heartburn and reflux. My symptoms have disappeared entirely and I am now a loyal fan of these products. Thank you.

    Several years ago, I was diagnosed with a fecal impaction way high in the ascending colon. My doctor told me to go home and use a good laxative. I stopped at the Vitamin Shoppe and was advised to try one of the Renew products but then also the IntestiNew for "soothing" the lining of the colon. That was the best advise I've ever had! I firmly believe the impaction damaged the lining of my colon and that the IntestiNew healed it! The Renew cleanse worked immediately but the colon was sore for about a week but the soothing actio of the IntestiNew made it bearable.

    About 6 years ago I took IntestiNew (along with several other products) for an Ulcerative Colitis flare-up that would not go away on allopathic meds. Within 3 months I was in total remission. Unfortunately, I seem to be in the beginning stages of a flareup (after 6 years in remission). I have re-started the same protocol that worked before, including IntestiNew.

    Five years ago I was diagnosed with Crohn's disease. A while ago I went to a seminar at Native Sun in Jacksonville, FL with Brenda Watson and Dr. Leonard Smith as the speakers. Crohn's disease was mentioned and they suggested IntestiNEW, a fish oil, and the book 'Eat Right For Your Blood Type'. That night I purchased the products. I still use IntestiNEW and a fish oil. After my colonoscopy, my Crohn's was in complete remission. I told my doctor that I was taking IntestiNEW by Renew Life (along with a fish oil and a change in my diet), and he couldn't believe it.

    I want to share my great appreciation of your product, IntestiNEW. Shortly after booking a European vacation, I began to have severe stomach problems. I chose not to go through medical diagnostic testing because of health insurance limitations. Thankfully I heard about IntestiNEW. Not only did I take the trip, I was able to eat almost anything I felt like. I continue to use the product twice daily. Again, thank you.

    Review by Tammy

    I have suffered from crippling diarrhea and cramping and found it difficult to have a normal life with my two small children. I was diagnosed with bleeding hemorrhoids and colitis. I learned about IntestiNEW and started taking double doses of it along with a FloraMore, a probiotic formula. Within three days I was symptom-free. I stopped the products and my symptoms re-appeared, so I started the regimen again and found relief. A few months passed and I had stopped using the products again and experienced more diarrhea and bleeding than before.

    I was scheduled for a colonoscopy for 6 weeks in advance. On my way home from the appointment, I decided to make some real changes in my use of these natural products that clearly had made a difference. I started again with double dose of both IntestiNEW and FloraMore, then when my symptoms disappeared, I went to a maintenance dose and have continued with it daily.

    I was totally symptom-free when I had the colonoscopy 6 weeks later. I told my doctor about what I was taking, but he didn't have much of a response. After the procedure, he came into the recovery room with pictures of my healthy colon. There was no sign of colitis. This very conservative gastroenterologist then asked what I had used and what the ingredients were in the products. I told him about Brenda Watson and Dr. Leonard Smith at ReNew Life and he requested more information from them.

    I continue to live free of crippling symptoms that once controlled me and my family. Thank you Renew Life!

    I have suffered with colitis attacks for years. A friend of mine told me about your product. I honestly didn't have much hope because I have tried many products to ease my intestine trouble. But since I had nothing to lose. After two weeks taking 2 doses a day I noticed my abdominal pain disappeared. Next went the abdominal bloating. Now things run like normal and all the pain and discomfort are gone. I have suffered for 10 years with intestine pain and irregularity and I cannot tell you how my life has changed because of your product. Thank you so much to your research department for caring enough to help those of us who struggle with these types of issues.

    At 43, I had dealt with some form of IBS for about 3 years. The MDs just wanted to push drugs and conduct invasive testing. Your product line was highly recommended. Two days after taking IntestiNew, I drove to my health store to find the lady who recommended your products, just to give her a hug. It worked that fast!

    I saw results immediately. I have been suffering from "stomach" issues for over 10 years. Most recently, I started having "acid" burning after a visit to the hospital where they started giving me conventional anti-acid medication. It was truly "fire in my stomach". My health care store recommended IntestiNew to me and I have been sleeping better than I have in years. Where have you been? I higly recommend to anyone with "fire in their stomach"...
