Gluten Shield – Digestive Enzyme Support for Gluten Cross Contamination
Avoidance of wheat products may not be enough to maintain a gluten-free diet. For example, did you know that gluten is used as a food additive and may be present as a stabilizing agent in salad dressings, ice cream, and even ketchup? Gluten Shield is an enzyme blend with probiotics designed to help maintain optimum digestion of all foods with a special focus on encouraging more complete digestion of complex carbohydrates in grains seeds, legumes, vegetables, and other plant materials. This formula also includes herbs to help reduce the symptoms of occasional food intolerances. For those who are considering a gluten-free diet, Gluten Shield includes both the enzymes that break down the polysaccharides which encase gluten as well as the DPP-IV protease activity necessary to digest gluten proteins. This digestive enzyme supplement is designed to help reduce the symptoms of occasional bloating, diarrhea, gas, and abdominal cramps associated with diets high in complex carbohydrates. Gluten Shield® does not promote the intentional consumption of gluten.
Does Not Contain: Gluten, Wheat, Dairy, Corn, Zein, Yeast, MSG, Fillers, Artificial colors or Preservatives, no Hidden Ingredients, No GMO’s. This is an all active formula, 100% vegetable sources. Safe for vegetarians.

I had trouble with indigestion. My friend recommended Dr. Osborne’s Gluten Shield and I keep it with me where ever I go. Indigestion is gone. Great product!
odette f. –
I am ordering a second time for my daughter who gets severe stomach pain after gluten exposure. She is 12 and may eat pizza with friends occasionally (for example). This has allowed her to enjoy occasional gluten without the painful side effects. Thank you for this product!! IT WORKS!
. –
What is the dosage per meal and when do you take it? Before, during, after meal???
Carolyn H. –
It is not unusual for celiacs,or gluten intolerant to lack the needed enzymes for digestion- I don’t have enough to digest fats- which are important ( omega 3s) . When we first used these a year ago on vacation to help with eating out – my daughter and I loved them and a year later we are still very happy with the way they help digestion
Donna M. –
I have been using this product for approximately 9 months now. I went one month recently without it and my tummy suffered. This is a solid product that I feel actually helps my digestion.
Kelly P. –
Because there is so much cross contamination out there, it is wise to always carry a bottle of Gluten Shield whenever you leave home. We use them on a daily basis even at home, as they help us digest our food better. Love this product!
. –
I am pleased to be able to go out to restaurants, take a gluten blocker, eat a
‘gluten free meal’ and not get sick as I usually do.
Kristin C. –
I’m never without my Gluten Shield! I’m super reactive to grain, so having this with me gives me peace of mind with every meal.
Ruth W. –
I call this my magic pill. Sometimes when ?I eat out and am uncertain as to Gluten I take this or even if I begin to feel awful I now know to take one of these Gluten Shield and I improve very quickly. My magic pill!
Beth R. –
I don’t digest my food well at all, and needed to try something new. I haven’t been using this product for very long, but I pray it is the one I have been searching for!
Lisa Z. –
I have been grain free,egg free,and dairy free since August. I have trouble digesting high FODMAP foods and had avoided them all together. Since I have taken gluten shield it helps me to digest foods like onions and garlic so I am able to enjoy some flavor with my meals. I intend on taking it before I eat my Thanksgiving meal this year. Although I still intend on staying gluten free,I know with gluten shield I have a safeguard in case I get accidentally glutened. Thanks Dr. Osborne for always looking out for us.
Stephanie O. –
I have been using this product for about a year. Since I am Gluten Sensitive, Lactose Intolerant, with Hashimoto’s this is a useful product to improve my gut and help me to better absorb nutrients. I have been happy with the results.
Beth R. –
Is Gluten Shield meant for every day, every meal? Or just occasionally?
. –
What are the other ingredients in the Gluten Shield?
Peter V. –
looks like a good product to deal with trace amounts of gluten when you can’t be totally sure of your food, like when going out
Beth R. –
Super product that helps much more than others I have tried for digestive issues!
Elaine B. –
really helps with digestion
Cathy B. –
I have Sjogren’s Syndrome and I needed a new digestive enzyme so I thought I would try your Gluten Shield supplement. The first time I took it I felt so much better! I didn’t have the pain or bloating that I’d been experiencing with my other digestive enzyme. Thank you so much!
Judith H. –
I was diagnosed with a gluten sensitivity and decided to try Gluten Shield. I haven’t noticed any difference so I don’t know if it’s working or not.
Diana F. –
It’s difficult living with a gluten sensitivity; there was a point I was so sick I had to take this with every meal. Fortunately, as my body has healed, I like knowing I can take these with me when meeting family at a restaurant; to help protect me against cross contamination.
. –
I travel a lot. I keep Gluten Shield in my suitcase. It really helps when I have to eat out.
Debi L J. –
good product

I have celiac disease, gluten free since 2001. Stopped a raging case of Graves‘ disease in its tracks by going on a gluten free diet. But that was just the start. I was 27 at the time, and had a lot of healing to do.
By 2008 I was on a strict gluten, peanut and dairy free diet. But I was still tired and was tired of gas and bloating. I found Dr. Osborne’s site, started taking gluten shield around 2009, and his multi vitamins (pill form not capsule… I forget what they are called).
I took gluten shield with every meal until probably 2016. I still have some on hand but have not taken it in a long time. It was probably a combination of healing, steady vitamin supplements (eventually switched to Ultra Nutrients), and identifying items in my diet that were not agreeing with me.
The gas only returns if I get lazy or I have tried something new that does not set well.
Gotta say, I have also followed Dr. Osborne’s Vitamin D frontloading each fall for the past 3-4 years and have caughr a cold only once since then. I also drink a Kombucha every day and if it is cold season or I feel a cold coming in, I will also supplement with zinc. Dr. Osborne doesn’t sell the Kombucha but everything else listed here I purchased from him.
I am grateful for his site and great information.
Lois R. –
I love this product! I know it is helping my digestion and helping to protect me if I get any cross contamination! I take it before every meal!!
Paula D. –
I have been gluten free for 7 years now. Gluten Shield is an awesome supplement for me. I carry it with me all the time, just in case!
. –
I have avoided gluten for over 11 years but have seen a desire to eat something, maybe once every couple months, and using this has made me feel totally free of repercussions. I forgot once and I was so arthritic…what a difference!
Megan H. –
I cook most of my own meals because of my gluten and dairy sensitivities. Gluten shield was helpful for those times when I was unsure exactly how my food was prepared, usually meals out or made by others.it was a little extra insurance on preventing the effects of gluten on my digestive system.
Sue S. –
Gluten shield has helped my whole family to stay healthy even as we dine out. We are able to enjoy meeting friends out without the worry of getting sick afterwards.
. –
I’ve been taking gluten shield for over 2 years now – and would not be without it. Occasionally because of traveling I eat where I’m not positive of every aspect of the food preparation. Gluten Shield is my ally – if I get any bloating or distention I take it – once I had to take a bunch of them, but a while later – excellent digestion again. So thankful for this product!
Cyndi C. –
I take Gluten shield especially when I eat out to help with any potential cross contamination. It helps my digestion so much that I end up using it even when I eat ay home.
Tabitha M. –
My son and I have both been using this product with great success.
Anthony P. –
Gluten Shield has made a huge difference in my life. I am sensitive to a lot of foods and liquid. So, now taking it with every meal, my ability to digest different foods has significantly increased.
Cathy B. –
I developed gluten intolerance about 3 years ago, along with SBO and Sjogren’s. I have tried several other digestive enzymes, but gluten shield made me feel the best. I have less bloating and pain after I eat anything, and I love that it helps with cross contamination (which is everywhere). I definitely take it when I eat out, but also a lot at home depending on what I eat.
Brigitte C. –
My son has been on the Gluten Shield for a while now. It has been a piece of mind every time he gets invited for dinner somewhere, and especially yesterday for Thanksgiving. Love it!
Julie D. –
I carry a pill box with a few of these for eating out just in case there is any accidental gluten exposure; helps with digestion at home too.
Nilima B. –
Been using for about 6 months. Just re ordered. Seems to be working well.
CINDY V. –
what a relief!
Marianne B. –
Just starting using Gluten Shield on the occasions when I cheat. Have been GF since August 2018 and has made a huge difference in my intestinal health. 99% better with IBS symptoms! Gluten Shield is great to have on hand. Dr. Osborne’s is awesome and is website is great! Thank you!

I’ve only had Gluten Shield for a short time. I have used it 3 times while eating out. One of those three times I did experience heartburn bad enough that I had to take an antacid. I was diagnosed with Celiac Disease about 9 months ago, and I am still struggling with bloating and heartburn from foods that I’m eating. I am looking into eliminating nightshades and possibly doing low Fodmap foods. The list of foods I can safely eat is growing shorter and shorter. I do enjoy eating out and was hoping the Gluten Shield would make a big difference. So far it has not, but I want to give it a fair try. I’m going on vacation in June and will be eating out a lot so it will be going with me for sure.
Jerry L. –
I’m sorry to say that I have not really given it an honest try. I will say that if I did not trust your science I would not have purchased this product. I bought this for my son who has autism. I have him on numerous supplements. Manny are trial and error. I drop off the ones that do not seem helpful. I will be trying the gluten shield for him shortly. Unfortunately the most difficult part is staying fast to an appropriate diet that does not contain wheat. At some point I hope to implement that. I think you for your follow up.
MARILYN O. –
Helps me greatly I now can go out to eat
Bonnie R. –
It really helps if you get glutenized by accident cant find any that work as good in other vitamin shops
Leigh S. –
I started having trouble digesting proteins in late January. While there are many enzyme products available,many that are Gluten Free have corn , soy or other additives . Thanks Dr Osborne for creating a product that doesn’t contain additives that can complicate auto immune issues! I also have peace of mind when eating out with cross contamination.
. –
It has helped me when I eat something that may have gluten it. So far no bad side affects!
Suz H. –
I was thrilled to find these products. I take enzymes regularly, but loved the idea of having this particular supplement to carry with me for the times I may not be able to control gluten sneaking into my food.
Brian J. –
Dr Osborne literally saved my life. I was having gluten issues unknowingly approximately nine years ago. I had every test imaginable by every type of test imaginable buy all kinds of doctors. None of them could figure it out. They said it was in my head. One even wanted me to see a psychiatrist. Fortunately a friend of mine turned me onto Dr Osborne’s website gluten free society.org . Once I learned about the true gluten free diet eliminating all grains including corn and rice. Two weeks after following Dr Osborne’s advice which I only Learned from his great website. I have been using gluten shield whatever I do venture out to eat at a restaurant and it works great. I strongly recommend taking Dr Osbornes advice. Even though I never met Dr Osborne personally I truly believe he save my life. I will always be grateful and recommend his website to his many people as I can.
Marianella A. –
It has helped me when I eat something that may have gluten it. I recommend It . awensome
Suzanne L. –
Is it dairy free?
Brigitte C. –
Getting quite a few supplements from Dr.Osborne. Gluten Shield is a great supplement that gives anyone who has gluten sensitivity or Celiac some peace of mind when eating outside the home. My son takes it every day. Great product!
JENNIE M. –
Does this help break down any other foods such as egg or grains?
Pamela E. –
Although I order menu selections that would be obvious for gluten ingredients, I now have the added reassurance when taking along my Gluten Shield, that sauces and condiments used in preparations will be taken care of.
Karen N. –
I think it is wonderful. I used it when I went on vacation, even though I ate gluten free I was afraid of cross contamination. It allowed me to enjoy my food knowing I had protection which is always heavy on my mind. It was wonderful to be pain free after a meal.
God bless you
Pamela T. –
I love having these as a safety measure when I dine out. They even work great to assist in digestion in a meal not containing dairy or gluten.
Perooz G. –
Good to have it just in case.
Marianne B. –
I have purchased my fourth bottle of Gluten Shield from Dr. Osborne. I was diagnosed with NCGS last year and went on a gluten-free diet. We eat out occasionally and since I don’t always know if there might be some gluten in the food I use the Gluten Shield as a added protection at those times. It has been a life saver for me as it allows me to dine out without the fears of the repercussions of unknown gluten in the foods I have no control over. It truly works well for me and if you are gluten-sensitive it is definitely worth a try. I never knowingly eat anything with gluten and that is NOT what Gluten Shield was designed for. This supplement is an added protection against the unknowns in your foods. Thank you Dr. Osborne for a great product!!
Charmaine M. –
I dont eat out since finding out after 20 years of suffering with RA that I am gluten sensitive, ( I did the genetic test). Having and taking Gluten Shield helps my digestion, I am so very glad I have it. Thank you Dr. Osborne.
. –
Hello – I don’t know what to say about Gluten Shield exactly because I can’t detect any impact. I gave it 4 stars because I love the idea of having something preventative to use when eating out or traveling…great to have! When home I use Dr. Bush’s Restore product prior to meals to close the gut junctures to assist with healing of autoimmune/Hashimoto’s/Vitaligo/Cancer Hx. I see this product as helping me perpetuate my healing intentions…I just can’t rate it for effectiveness with no clear evidence. Thanks for asking
Daisy M. –
I have a very difficult time with all sorts of foods specially eating out. This surely has helped minimize the symptoms as even if you avoid gluten foods cross contamination is very common and I can notice it immediately. This is a great product which has helped with those issues. I carry a bottle in my purse all the time and keep one on kitchen.
Diane C. –
I’ve tried other products that claim to help is a person accidentally eats gluten, but Gluten Shield is the only one I’ve found that really works. I’m so glad I found it!
Diane C. –
I’m not sure if I entered my email correctly, so I’ll resubmit my review. This is the first product of its kind that actually works for me! I’m grateful to have found it.
Joy S. –
I bought gluten shield because I was concerned about all the holidays festivities and the difficulty in avoiding gluten. In certain situations, while still making wise choices, I was able to relax and enjoy because I had gluten shield. It helped me avoid adverse reactions while still being able to socialize.
Renata B. –
Being gluten and dairy sensitive, I have tried another product in the past but did not see the results that I did with Gluten Shield. I consumed a small amount of dairy over the Christmas Holiday which usually results in an earache and blistering inside my lower lip. I experienced none of the usual side effects using Gluten Shield. Thank you so very much.
Gabrielle L. –
Going gluten free has now become essential for me so this product is a must. There are a lot of GF enzymes out there but Dr Osborne clearly is a leader in this field. I’m completely satisfied with this product.
Gabrielle L. –
I’ve tried 5 different brands of enzymes containing the important DPP-IV peptidase, and this formula seems to have the best variety of digestion enzymes & high gluten protection (for hidden gluten consumption).
Jennifer M. –
I’ve used this few times for dining out and family gatherings, just in case. I didn’t suffer any ill after effects. An extra bonus was that I had better bowl movements after taking these too.
Esther B. –
Love Gluten Shield. I don’t have the stomach discomfort I had prior. Thank you!
. –
I like it, I think it is a good product. what I like the most is how fast I got it, and I am in Canada !
Brigitte C. –
I love this supplement! It gives me a peace of mind when my son eats at my parents or friends. It is well designed for those with gut issues. Thank you, Dr. Osborne!
. –
Thank you for this product. I donʻt use lactose pills anymore. Just Gluten Shield.
Layla N. –
I can finally eat just about anything, dairy included. No more gas or bloating. I just pop 1 pill with each meal and enjoy my snack or meal! Thankful for such a great product.
Dana G. –
I have used this product for several years now and it has been a life saver, especially when traveling. I am extremely sensitive to cross contamination so traveling requiring eating in restaurants is a big concern. With caution in choosing the type of restaurant and taking gluten shield, I can avoid having a bad reaction. I rely on it daily as well because I also have a problem with low stomach acid which it helps counteract.
Richard P. –
As a gluten person, as well as a certified gluten practitioner. This product does what it says. There are other out there, but this is the best. Beware, this doesn’t allow you to eat gluten. Just use if you get “glutened” by mistake.
. –
It is great to have a product handy for those times when you are out for dinner or with family and friends and are unsure if the food is truly gluten free. This product has really been a life-saver! Thank you again Dr. Osborne!

From testing I learned that I’m gluten sensitive and was also having episodes of atrial fibrillation. So I began eating Keto and taking heart healthy supplements including gluten shield. I have since lost 30# and easily kept it off and hardly ever have any afib. I am gluten free but felt Gluten Shield would protect me from sources I don’t realize have small amounts of gluten like proteins. Who knows exactly what of my changes has brought about these great improvements in my health but I’m not giving up my gluten shield to test it. 😁
Jennifer R. –
we are glad to be able to go out to restaurants, take a gluten blocker, eat a
‘gluten-free meal’ and not have to worry about potential cross-contamination. It gives us great peace of mind.
James B. –
This item is perfect for me to block any gluten if food is contaminated.
Tina B. –
This supplement is a game changer. I always carry them in my purse and pop one when I go out to eat. I have Hashimotos disease and gluten does a number on me. No issues when I take my Gluten Shield. I know they work because my mom also has Hashimotos and we went out to eat. I popped a Gluten Shield. She did not. We shared a “gluten free” dish. She got a tummy ache. I felt fine. Now she always carries Gluten Shield with her. Love this product! If I could rate it a 10 I would.
Wanda D. –
Very helpful, can tell a difference using it, excellent product
Jennifer Z. –
Life changing. Was experiencing changes in digestion. Tried Gluten Shield on a trip to Italy to protect against accidental gluten contamination and noticed within a couple doses all my digestion issues resolved, no more bloating, BM’s back to normal. Thanks for a great product.
Bronwyn S. –
I take one capsule every day. I have had fewer digestive upsets since I’ve been taking Gluten Shield
John T. –
Excellent product. I use it whenever I eat out.
. –
I like it so far, but I have only used it once. I was not living in the States when I ordered it, so I had to wait till I got to my brother’s to
try it.
Michael Sr P. –
Only used it once since learning of my gluten sensitivity; trying to follow Dr. Osbourne’s advice and not eating out. But now that we are into the Holiday Season, it is tough to tell all the friends that one will not attend their parties. Only some friends prepare safe foods, so plan ahead and get the needed protection.
Lisa G. –
This is the only supplement that I’ve felt comfortable using at meals when I’m warey of cross contamination of gluten. I am gluten intolerant and do not want to have any gluten symptoms, so I take these when I go out to a restaurant or a friend’s (that offers both gluten and gluten free items).
Janice M. –
I use this product every time we have to eat away from home. Don’t seem to have any reactions to unsuspected gluten in foods.
Tatsushi F. –
Gluten shield is absolutely a life saver, cannot live without it. My current project with this product is to fine-tune the exact amount needed to effectively defend against a particular food item, as clearly, taking more than a necessary amount is wasteful, and perhaps, counter-productive.
Kim D. –
This product works! I highly recommend it. This is the best product out there if you need help digesting gluten.
SAMANTHA L. –
A Christmas present in itself. Took it with me for our Christmas travel and it took care of any potential bloating or tummy aches!
Vanessa H. –
Excellent product. Helps give me piece of mind in case of contamination. Fast delivery.
. –
I started taking the recommended Vitamins from Dr. Osborne and a week later started feeling much better.
Benedetta D. –
I’m gluten sensitive. I use Gluten Shield when eating out.making sure to take it in advance as suggested.
We travel a lot and Gluten Shield is my safety blanket. I never leave home without it!
The price is very reasonable too.
Kathryn S. –
I have used this product for several months now. I take it almost after every meal. I have issues with heartburn and acid reflux. It does help with my digestion. I am Gluten sensitive. So Gluten shield along with the Dairy Shield is always with me when I eat out. I do not intentionally eat gluten but at times we can not always control what is in our food. This product helps me deal with digestion but also any accidental gluten ingestion.
. –
I like to have Gluten Shield on hand for the rare occasions I eat out and am accidentally “glutened”. It gives me peace of mind.
Tsubomi i. –
As someone who suffers from RA and has a sensitivity to gluten and grains, I’ve been following a strict gluten-free diet for the past two years. Seeking extra protection against gluten contamination, I decided to try Gluten Shield, taking it twice daily. Surprisingly, amidst my recent treatment for an H. pylori infection, I found that the supplement seemed to aid in detoxification, despite this not being mentioned in its product description.
I discovered that Gluten Shield complimented my herbal treatment protocol, exhibiting a synergistic effect. Initially, I experienced some die-off symptoms, but soon noticed relief from the stomach pain and bloating associated with the H. pylori infection, which had been persistent before.
In addition to its gluten protection, I found that Gluten Shield boasts a remarkable digestive enzyme blend, which has greatly improved my overall digestion.
Jewell B. –
Your product was introduced to me by my son. This product has been very helpful and I would not hesitate to recommend it to anyone I know with gluten issues.
. –
Will purchase again. So glad that this product is available for those who need it.
Lavena F. –
This is a wonderful product. Will not be without it. My husband is not gluten free so he cooks in the kitchen with gluten. This product save me. Thks so much
. –
I started using gluten shield right after I tested positive for gluten sensitivity. It gives me a sense of peace of mind knowing that if I get exposed to gluten either directly or indirectly I have taken something to mitigate the risk of the gluten exposure
Jewell B. –
I tried your product for the first time a year ago. I continue to watch what I eat but I’m at peace knowing that your product will help reduce the discomfort associated with gluten exposure. I will continue using Gluten Shield and highly recommend it to anyone with gluten issues.
LAURIE C. –
Great Backup; I love this product for eating out and on the road traveling. I have had to send food back while eating out that had GF attacked to the menu but mistakes were made. Now I just assume there will be a problem and take my shield before eating to protect myself.
Margaret R. –
I like it. It seems to be helping somewhat.
Therese G. –
I feel better since I began using this.
Denise N. –
I am never without at least one Gluten Shield anywhere I go. My meals are typically home cooked gf/df/ and grain free, but occasionally I would like to go out to eat with my husband and friends. (Usually I send him out with friends and just stay home so I’m not glutened.) However, this product does allow a bit of freedom to at least hang out with friends and eat some grilled chicken and salad without the excruciating pain, brain fog, cystic acne, and itching that ensues from eating the occasional food that is said to be gf but is not.
I don’t have to use it often, but I’m thankful to have it should the need arise.
GIRALDO F. –
used for some time and it does help with digestion…..Thanks for this great product
