This, along with some other supplements and diet, has healed my gastritis
Backstory first for context, method for improvement to follow. All supplements are Bold for convenience. Note: This is just my experience and should be taken as such. It could serve as a place to start or a place to continue with experimentation if you've already begun trying different things yourself. Backstory (feel free to skip to the 'method' portion if you've already been down this road before): I was diagnosed with SIBO about 7 years ago. Had a healthy diet, never smoked, no drugs, stayed away from NSAID's, barely ever drank, and it showed up overnight. Discovered the low FODMAP diet through my dietician a few years later and she identified my particular FODMAP that was the biggest issue (Fructans) for me and it changed my life. I also took a digestive enzyme (Digest Gold) and supplemented with a multi-vitamin, vitamin D, and Zinc. I also took a fiber supplement to help slow down digestion (Heather's Tummy Fiber) every day. These things, along with stress management, made me as normal as I could've hoped for relative to the time before having to deal with these issues. The daily bloating was pretty much always there, but given that BM's were regular, no pain, no fatigue, sleep was good, blood levels were good, etc. I figured I was doing fine for someone in my condition. I suddenly began having terrible GERD symptoms about 3 years ago out of nowhere and couldn't believe how bad it got so quickly. Horrible esophageal pain, indigestion, fatigue, you name it. I began supplementing with betaine HCl (Now Foods) and it was like a miracle. Within a week almost all pain was gone, fatigue went away immediately, could sleep through the night, everything improved. I was even able to ween myself off of them after about a year and was GERD free. Skip ahead to New Year's this year (6 1/2 months ago now) and got terribly sick from a party I attended. Tested for Covid and it was negative, but the symptoms were the same as the first time I had it last year so it could very well have been Covid again. Horrible fatigue, even passed out while walking at home at one point. Stomach became even more bloated than normal, food sat in my stomach forever and felt like concrete sitting in there, even got down to 2 meals a day. I figured it might be just my system taking its time to readjust after being so sick, but it didn't improve. Later in January I went through an incredibly stressful period of about 2 or 3 weeks which was the icing on the cake. Right after that (about mid February) I started having stomach pain in a way I haven't felt before. It was a burning that was consistent throughout the day, particularly (and curiously) mostly after drinking water usually about an hour or so after a meal. This also evolved into heartburn again. Symptoms included the usual: fatigue, upper abdominal (stomach) and esophageal pain, diarrhoea, etc... This is always scary and malnutrition becomes the first thing on my mind when anything like this happens, so I take it very seriously. I began supplementing with HCl again in an effort to mitigate the heartburn, not really knowing what the extra stomach pain was. I know that you're not supposed to take HCl if you have stomach ulcers, but never having dealt with that before and not having been tested for gastritis yet I didn't know what else to do. An important note to this is that they did in fact alleviate my heart burn, but didn't do anything for the stomach pain (no surprise). Once the heartburn was gone I gradually tapered off the HCl and relied on diet and supplements for the gastritis pain. The heartburn has not returned since. It's worth mentioning that I had a wonderful doctor, dietician, and Gastroenterologist a few years ago, but they have since all left their former jobs and started private practices. Good for them, but sucks for those of us who benefitted so much from their understanding and willingness to be open to alternative methods of medication that aren't just pharmaceuticals. I'm not interested in just going with what a doctor who just pushes drugs and has no actual experience or knowledge about an illness says at this point. Too many people suffer because of this kind of negligence and I'm disciplined enough to find methods that aren't pills that will most likely make me dependent on them or worse yet, make the initial condition worse (or give rise to a new one). I've had much success with different methods in the past and plan on continuing finding them when a new issue arises, even if it takes longer to find relief. About three months ago I decided to see my current doctor anyway since I wasn't sure how to deal with what I suspected was gastritis. We did a breath test for H. Pylori which came back negative, and other than confirming that she thought it sounded like Gastritis had nothing important to add. Nothing about diet, supplementation, or anything of the kind. Gave me a prescription for an H2 blocker which I have not touched since getting it and told me to set up an appointment with a GI doc to see about an endoscopy. I did set this up, but my initial consultation wasn't for another three months so I decided to do some research on my own and do what I always do: take action into my own hands and listen carefully to my body. That doctor's visit was back in March and the GI consultation just happened this past Friday (it's now June 19th). Method for improvement: Step 1: Diet -The first thing I did was adjust my diet again. I had heard red meat was a huge trigger for gastritis pain and sure enough, as soon as I cut it out I felt more relief. Chicken caused a little bit of an issue still but better than red meat, and I noticed fish like Salmon and Tilapia caused the least. Eggs were no issue at all. Raw nuts were good too. Certain fruits like blueberries, strawberries, kiwi's, were all good. Veggies like bell peppers and spinach were fine. I cut out grains like rice and quinoa because I felt as though I had more pain after eating those, so anything that even seemed like it could be a little bit of a trigger I cut out. Non-fat yogurt like Sigi's brand seemed to be okay too, and hard cheese like Gouda felt fine. I would have OWYN protein shakes with almond milk and peanut butter once a day too as it's a quick, easy way to get nutrients, and I noticed it didn't bother my stomach at all. I added some Manuka Honey into the rotation much more recently as well and actually felt a positive difference there too. All this, aside from the Honey (since I have to be careful with it anyway due to SIBO) was pretty much all I ate for 2 1/2 months. -As a side note about diet: I drink real loose leaf tea daily and was probably more reluctant to give up that ritual than any food. Particularly, I drink high quality Ripe Puerh tea almost daily which helps with digestion and calms my stomach. No additives, no herbs, just the tea leaves. I noticed that the thing that triggered my gastritis symptoms more than anything was drinking water after eating (I would usually wait about an hour to drink anything after a meal to give my stomach as much time to digest as I could), but this kind of tea not only didn't hurt, but it actually seemed to alleviate stomach pain after drinking it. In list form for convenience: -Eggs, Chicken, Fish, non-fat yogurt, hard cheeses -Spinach, bell peppers (steamed) -Blueberries, strawberries, kiwi -Raw nuts (walnuts, pecans), peanut butter (all natural if you can get it) -OWYN brand protein powder (Vanilla as chocolate can be triggering for gastritis) -Ripe Puerh tea (whole leaf only, not tea bag dust) Step 2: Supplementation -The first supplement I tried called Zinc L-carnosine (Doctor's Best). I had heard this helped heal the stomach lining and even showed efficacy in the eradication of H. Pylori overgrowth in some studies. Even though I didn't have an overgrowth of this kind (as far as the breath test was concerned) I figured I might as well try it. Within the first few days I noticed a change. The pain stomach pain was less intense throughout the day and I felt a had a little more energy. -The next was Mastic Gum (Horbaach). Of all the supplements I've tried this seemed to be the least noticeable as far as the difference it made is concerned, but I believe it helps for the following reason. I take two a day and, although my symptoms were steadily improving week to week the difference showed up most when I took three a day. My stomach pain was reduced to almost zero in the four days I tried three a day along with the Zinc L-carnosine. Unfortunately and curiously, even though my stomach pain was almost entirely gone, I experienced increasing bowel discomfort as well as irregular BM's. I cut it back down to two a day again and the discomfort went away, but the stomach pain increased slightly again. This seemed to suggest that three was optimal for my stomach, but less so for my bowels. -I also take a twice daily probiotic (H. Pylori fight from Supersmart). Again, not convinced this does too much but I did notice a bit more BM improvement after beginning this one. -More recently I started putting Colostrum (Happy Cow) in my protein shakes and have been astonished at the difference this has made in my bloating. I also feel like I'm digesting better and have more energy throughout the day. -It has been six months since I began having issues and just over three months since I began a more specific method of dealing with it and here's the most important thing I've learned so far: Strict consistency with diet and supplementation have been the biggest factors in improvement. Over the last month I have had a few glasses of wine on separate occasions with zero discomfort on 3 out of 4 of those occasions. I have added rice and quinoa back into my diet with no adverse effects. I even had a little beef two nights in a row and zero pain/discomfort. I sleep through the night every night now and have not woken up with any pain or discomfort for over a month. Every week is better. I expect to follow this regimen for at least a couple of more months, and will then slowly taper off supplements to see how I balance out. I've accepted that chronic health conditions are chronic precisely because Doctor's don't know what to do with them short of throwing pharmaceutical drugs or surgery at it and hoping for the best. If they knew how to cure them they wouldn't be chronic. Sure, there are people for whom those things can and do work for and some who have even had their lives saved because of their doctor's intervention, but these issues are complicated and individual and there are often no better resources than other people who have had their own experience with your condition. Yes, there are also people who don't have the patience or money to add supplements or dietary changes into their routine, but if you are able to it's worth giving a try. Please don't overuse supplements and be disciplined with diet once you find something that works for you. Yes, overnight results happen for some, but do not expect it. Be patient and follow it daily. Listen to what your body is telling you and adjust carefully based on this. I am not a woo-woo naturalist, I just have very little faith in the medical system to know what to do with chronic health conditions and accept, after having seen multiple doctor's, gastroenterologists, and dieticians (some wonderful and helpful, some not so much) over the years, that very few actually have the interest in finding out what's wrong with us and would rather throw a band-aid over a bullet hole because "that's just the method they use". Keep in mind this is only what has been working for me, not what will work for everyone. This stuff is miserable to deal with and can feel lonely, hopeless, and isolating. I'm not telling you it isn't. But if there's something you haven't tried or haven't tried for long enough to really know then try to keep an open mind. Good luck. UPDATE: About a month and a half after writing this and my diet has expanded again and I have next to zero discomfort or pain of any kind. I'm now down to 1 Mastic gum, 2 Zinc L-carnosine, and 2 H. Pylori Fight per day. The discipline for supplementation and diet has paid off it seems. I have to remain cautious, but I feel none of the worry and pain I did even at the time I wrote this original post.

AMAZING. Doctors should be prescribing this instead of PPIs and H2 Blocker. UPDATED-12 months of Use, Foods to eat and Avoid
I ripped up my stomach on caffeine pills during one semester as an engineering student, and I developed severe gastritis. I was nauseous all day long, facing sharp painful cramps, it was absolutely incapacitating. I've been on PPIs and H2 Blockers, but the PPIs only made it worse and the H2 blockers didn;t do enough. This compound has been a gift from God, and I have not felt this good in a year. It will not solve any underlying problems but it does wonders for the stomach lining. In addition to avoiding foods that irritate your stomach, take 1 of these capsules with every meal (3 capsules a day total). I felt a difference within a week and after doing this for a month I'm well on the road to recovery. I still cant have foods containing caffeine, but I no longer am nauseous or in pain. I'm on my third bottle, feel free to ask questions. I know how much of a struggle stomach issues can be. UPDATE: I'm proud to say that after being on a PPI (Prilosec) or H2 Blocker at some point for the last 15 months, I have finally been able to get off of both them! It's a long process, and I've been taking 2-5 of these a day for the last year. I HIGHLY recommend this product, it helped me tremendously. UPDATE 2 (6/20/16): I have been blessed so much to be able to stop taking these. After 2-5 per day for about 20 months, I no longer need them. I'm continuing a slow recovery and adding back foods into my diet that used to cause me pain.This product was a key part in aiding the healing of my gastritis. I still endorse it - I've bought probably 15+ bottles over those 20 months and I would do it again. Here are my gastritis BLACKLIST (foods to avoid) and GOODLIST (foods that are safe and gentle for me). This is a copy and paste from my food journal. Your mileage may vary, so always try foods from my GOODLIST cautiously. THEBLACKLIST: Caffeine (patient zero) Theanine cough drops strong mints tomato sauce ketchup alcohol cajun seasoning hot sauce (Frank’s mild) hummus all chocolate, but especially dark chocolate maybe carribean jerk marinade Minute Brown Rice (maybe too much fiber, Uncle Bens Instant Brown is okay, could be because Minute is Precooked rice) Bush’s Country Style Baked Beans ( am okay with KC Masterpiece Applewood Smoked Bacon though) Stress mustard Vinegar (from cole slaw specifically) fake bagged popcorn for some unknown reasons pickles Hydrogen Peroxide from Crest Supreme WhiteStrips (60 min duration, VERY little swallowing, made sure of it, it’s hard to get it all out of your mouth Very Fatty and Greasy Pulled Pork ( from Uncle Buck’s BBQ) green peppers greasy alfredo sauce from pizza hut Literally any large super fatty meal Sourdough pretzels Country Crock Buttery spread Fatty Meats Apple juice honey coated peanuts THE GOODLIST: pita chips white rice (old bens) pasta with olive oil baked potatoes eggs bread nuts peanut butter pretzels milk fish (lean fish like flounder, salmon, snapper, or tilapia) beef yuca / casava ground turkey canola oil ( for cooking, in place of butter/margarine)

You'll be glad you did. Just buy it.
Okay I'm going to need you to hold onto whatever you're sitting on.. because this is going to blow you away. First off, I was skeptical of the reviews/ratings. Because how can a product with over 5K reviews and a solid 4.4 stars, I might mention, be THAT good? Nah.. But hey, I decided to give it a shot. Who knows? Maybe it'll actually help. As someone who has suffered from gastrointestinal issues for many years, I have been searching high and low for the most effective supplements without the high bill. My gastro issues had a domino effect and I succumbed to GERD, esophagitis, and gastritis to mention a few. These led to a constant unpleasant sulfur odor being emitted from my lungs/mouth without me having any control of this. I knew I desperately needed help. As someone who enjoys being social, gatherings became a big problem for me and mild depression began to set. To preface, I have tried everything from L-glutamine, Betaine HCl with bitters, turmeric/ginger capsules, probiotics, prebiotics, kefir, mastic gum, oregano oil, to fermented food and/or vegetables. Of course each for different purposes but all with the intent to eventually heal my detrimental stomach lining these gastro issues have caused. Desperate yet still hopeful, I came across this supplement and noticed beneficial effects from day 2 of use. Here's what I do- I take 2 capsules of Zinc Carnosine + Magnesium Glycinate every night before bedtime and I can literally feel the decreased inflammation when I wake up. There's no pain, no cramps, no bloating. I feel back to my normal self again. Is this a miracle pill? Probably not, but I will say it has significantly benefited me. I just wish I had my own personal endoscope to visibly see the dramatic effects but based on my symptoms, I am confident this is working. I am not fully healed but I'm only a week in and I am loving the effects. The sulfur odor is reducing, my stools are looking great, my brain fog has lifted, and the bloating is minimal. Just know- the key is consistency. If I can do it, you can too! I believe in you and your little healing gut. We got this!

Zinc Carnosine complex supplement for possible stomach and GI benefits
I take a selection of vitamins and supplements daily. In deciding to incorporate these into my daily routine, and in order to determine as best I can what the proper supplements and dosages are that I should take, I initially relied upon guidance obtained from Eating Well for Optimum Health: The Essential Guide to Food, Diet, and Nutrition among other resources. This Zinc Carnosine complex supplement is not from any of the books I've read but rather is something I've added on my own very recently, frankly based only upon mention of this as a beneficial product to take for stomach and GI health. When I first purchased this product on Amazon, back in November of 2015, it was labeled 'Doctor's Best PepZin Gl (37.5 Mg)'. I re-ordered the exact same product this time without closely noticing the labeling, and after receiving it I see that the label now reads 'Doctor's Best Zinc Carnosine Complex with PepZin Gl'. The ingredients appear to be identical although the recommended 'serving' is now stated as two capsules when previously the recommendation was a single capsule. I take one of these daily. I take this simply for the possible benefits I might receive, also expecting that there are no real detrimental effects. I do not claim to be able to detect any significant benefit to myself personally from taking this product nor have I attempted to analyze the benefits I receive from the combination of supplements that I take in order to determine which benefits derive from any of the individual products. These capsules are non-GMO and do not include any glutens or soy. The ingredients list does not mention any dairy products, soy, sodium, sugar or artificial preservatives, sweeteners or colors. I am not a long-time Doctor's Best customer and this is the only product of this company that I am presently using. I am satisfied with the quality.. This is one of the better choices available on Amazon for Zinc Carnosine capsules in my opinion. If I do later determine that there is an equivalent, or better, choice available, I'll update this review to provide that information.

Patience Required! But It Works!!
This is a long review because like many of you, my journey through acid reflux has been a slog. I have tried more “reliefs/cures/stops”,etc. than I can count. I will start at the beginning and try to briefly tell you what I have done in the hopes I might help some of you, as reviewers have helped me. First, I went on Omprezole about 15 yrs ago. My reflux got progressively worse, where the acid was coming up as soon as I bent over or lay down. After a few years this would happen even 3 hours after ingesting food or drink. So, I started researching and found out how bad PPI’s (Omprezole) was for your body and that in fact I was making things worse. So, stopped taking it, relying on famotidine, and a variety of other acid relievers. I did not know that my body had become addicted to the Omprezole and that the acidic symptoms would become worse. I stayed off it though, using famotidine and everything else at hand, and did more research. I learned that it can take months to recover from the addiction, and not to worry about taking the other stuff so long as I was stopping the acid from burning up my esophogeal lining. That can lead to cancer. I learned to raise the head of my bed 6 in, and not to lay on my right side (huge to stop the reflux). I also began eating my last meal no later than 4pm, because my food was not emptying normally from stomach to intestine. I was getting better, but now needed reduce the famotidine and the amount of calcium carbonate products I was using. I started supplementing my acid relieving products with DGL chews, Slippery Elm or Sodium Bicarb (½ tsp with water) to help heal my throat linings and neutralize acid. Fast forward to January of this year. I learned that I actually was suffering from low acid, causing my food to sit in my stomach too long. I read about Pepzin, a product that has been around for awhile, and BetaHCL with pepsin and bitters. I followed a reviewers regimen and started with 2 Pepzin in the morning on an empty stomach, then after eating lunch or dinner I tried the BetaHCL w/pepsin. The full capsule of the BetaHCL was like a time bomb of acid going off in my stomach, so I didn’t use it again until later in a small amount only when I thought I needed an extra boost to break up the food. I also find Papayra Enzyme chews (cheap) helpful after a large meal. Now I am learning (Utube videos) how to manually stimulate my esophogus sphincter valve to close and the lower stomach valves to open so my stomach contents will be released into the intestine. It is 4 months since I started the Pepzin every morning, and I can’t remember the last time I needed to take a famotidine. I rarely need to take anything to stop reflux and know my digestive system is healing nicely. I am a 73 yrs old woman, and don’t know if my body will every fully return to normal digestive functioning, but I do know now that I don't need to suffer and be reliant on those drugs. And, btw, I did not change up my diet. I can still have a beer or two when watching a ball game for example. I know my triggers though, and try to be reasonable. I hope this long review helps someone! Don’t give up!!!

Cures Leaky Gut
Dealing with leaky gut? (Gastritis, IBS, nausea, burping, sharp stomach pains, reflux, ulcers, bloating...) This is not only the only thing that heals it, it's the only thing that is safe to use. I've been dealing with leaky gut symptoms for a year. Changing my diet did very little to help. I stopped eating this, stopped drinking that, it didn't matter. This PepZin Zinc L-Carnosine is the only thing that worked. Why? Simple, we don't no longer get zinc in our diets. It's not in the water supply, it's not in our foods unless you eat a pound of beef every day or oysters. The Zinc in vegetables is chemically bound to other substances that your body can't break apart. What we do eat typically (sugar, filler, fake sugar, caffeine) massively use up zinc. Exercise uses up zinc. Stress uses up zinc. Turns out we need zinc to make the coating for our stomach walls, hence, why we have "leaky gut". In just two days of taking this, my burping, and reflux went away. In just 4 days of taking this, my bloating went away. My stools look healthy now. Best of all, this zinc is so light on the stomach, and digests so slowly, you never have to worry about getting nausea. This is far more effective than prescription drugs like proton pump inhibitors. But it's an affordable over the counter supplement. Doctor's Best has a loyal customer now. Their magnesium supplement is also highest quality in the market.

Might work for acidic stomach but not for reflux of unknown causes
I've had severe GERD for years. And when it was discovered, the gastroenterologist was not interested in finding the cause, but only a pill-and-surgery solution. The purple PPI that I was prescribed made me sicker and it gave me uncomfortable esophageal spasms (so I stopped taking it). And the possible surgery would have created a permanent situation that might be uncomfortable and then couldn't be undone. So I began to self-treat with DGL and some lifestyle changes (small meals, not too close to bedtime, acupuncture, probiotics, etc.) I've been dealing with it on my own for years, due to disinterest from my doctors. Recently I saw the positive reviews for this product, and I decided to try it at bedtime to see if it could minimize any nighttime reflux. The next morning, I woke up with sinus issues, a raw throat, and a harsh feeling all the way down my esophagus. It was as if my whole system became acidic overnight, and somehow I refluxed worse than ever. So obviously this is not a solution for all reflux situations. And since I still don't know the root cause of my issue, I'm guessing my situation is different from the people who got relief from this product. This product is likely helpful for people who produce too much stomach acid, and for them, it's more effective than prescription drugs or OTC tablets. In my case, my reflux might not be caused by "too much acid," but something else. Don't take this if you're not sure.
