Most Important Supplement to Relieve Heartburn – D-limonene!

If there were one magic bullet, that could improve reflux symptoms it would be D-limonene. A chemist, Joe S. Wilkins from Texas suffered from GERD for years and searched for alternative treatments. He was working with orange oil trying to formulate natural cleaning products, and he accidentally consumed some of the limonene that was left on his hands.1 After drinking the D-limonene, he noticed that his heartburn was gone and his esophageal inflammation was relieved. D-limonene is an extract from orange peel, which has an extremely low toxicity to humans,2 and is GRAS (Generally Recognized as Safe)3 as a food additive and supplement. Research has also shown that D-limonene might also have anti-cancer properties.4 5 6 7 The daily intake of just one 1000 mg soft gel of orange oil every other day for twenty days has been shown to reduce or eliminate GERD symptoms in most people for six months or longer.8

Orange oil is lighter than water,9 so it floats to the surface of gastric juices in the stomach. When someone is refluxing, orange oil coats the esophagus, protects the esophagus from acid and gastrin, reduces inflammation, and helps heal erosions.10 D-limonene also increases vasoactive intestinal peptide production which promotes proper motility, secretion of bicarbonate and water into pancreatic juice, stimulation of bile production, regulates stomach acidification by regulating pepsinogen and gastrin production, and helps limit osmolarity in the intestines (prevention of diarrhea). VIP is also anti-inflammatory, realigns a stressed circadian rhythm, reduces anxiety, and has antimicrobial properties. D-limonene also increases gastric emptying, improves stage 2 liver detoxification, and increases bile production and release. D-limonene has strong systemic antiviral effects against the virus family Herpesviridae (may help against Herpes Simplex 1, Herpes Simplex 2, and Varicella [chickenpox, shingles] reactivation). Finally, D-limonene increases GABA production in the brain, reduces glutamate excitability, and may prevent serotonin overproduction (which may improve mood and reduce anxiety and brain fog).11 12 13 14 15

So how does D-limonene improve reflux and stomach trouble? Orange oil, when burped up, coats the esophagus, protecting the esophagus against caustic contents that would have otherwise been regurgitated from the stomach. D-limonene may stimulate quicker gastric emptying, so less gastric acid, bile, pepsin, and endotoxins remain in the stomach to be refluxed.16 By increasing gastric emptying time, orange oil also reduces fermentation in the stomach and the duodenum, relieving bloating and gastric pressure, reducing reflux. Finally, D-limonene might inhibit Gram-negative upper gut bacterial overgrowth like H. pylori and Provetella, leading to a reduction in endotoxin inflammation and reflux, reducing inflammation in the duodenum, stomach, and esophagus. D-limonene might also help improve the stomach mucosal lining and promote the healing of ulcerated tissue.17

I do caution the use of D-limonene in people with an elevated Th2 immune system (histamine intolerance or mast cell activation disorder) or individuals with severe gastritis. D-limonene may make people with these medical conditions have a flare up, upon use and therefore should be avoided. Other rare side effects of orange oil supplementation are increased esophageal inflammation, aspiration, and breathing issues.18 19

I recommend that you either use the limonene supplement Orange Burps, in easy to swallow softgels. In addition, be sure to follow the supplement instructions as well. Most people take limonene with a meal to prevent gastrointestinal upset. Orange oil is very important for protecting the esophagus and stomach, relieving inflammation in the digestive system, and reducing and preventing dysbiosis. I recommend trying it if you are dealing with heartburn today and find some relief.

  1. Just starting to take D-Limonene and taking 1000 mg every other day for 20 days. Should I continue to take my Ranitdine 2X a day until the 20 days are over, or just take it if I feel I need to?

  2. Thank you for this information. I took a bottle of the 1,000 mg according to the protocol, and it did help, but it didn’t cure my GERD. I had an endoscopy and found I have Class C esophagitis and gastritis. I bought the liquid D-limonene and started taking one drop a night before bedtime. I gradually worked up to 4 drops over the past month, but am also taking Zantac 150 4x a day by doctor prescription. My GERD is still there, and I dare not miss an acid blocker pill, or it gets worse. My doctor gave me 12 refills of the Zantac, so I’m assuming he expects me to take it forever, but I don’t want to, so I’m going to try to wean myself off after 2 months on it. I’m taking the D-Limonene daily, since I’m not sure of the dosage for the liquid. I sort of judge it by the burps. Once I stop burping after a dose, I increase it. It does seem to be helping with my depression and sleeplessness.

    I read somewhere that you should take the 20-day protocol, then get off it for awhile. I also read that large doses are not usually harmful, but nowhere have I seen if it’s safe to take every day. What do you think?

  3. Hi John, thank-you for your page! I started my son and Husband on D-Limolene and in my research I really liked the effects it can have, so I started the jarrows formula for prevention. Is D-Limolene safe to take daily indefinitely fore protection (as my Mother had breast cancer and I have been proactive)?

    • Dear Michelle,

      I cannot say it is safe for daily usage, but it has been taken daily for months in studies with great toleration.

      John

  4. Can you take d limonene indefinitely? I tried the 20 day course and felt marginally better but now I have acid teflux 24/7. I only take bicarbonate and water to ease pain. If it’s safe I’m happy to continue it everyday second day forever.

    • Dear Cassie,

      I cannot say it is safe for daily usage, but it has been taken daily for months in studies with great toleration.

      John

  5. If I don’t have a gallbladder can I still take D-Limonene?

  6. Have you read anything that would indicate this D-Limonene can dissolve gallstones?

  7. Thank you John. Very well researched and written blog. I got a lot of good information from your site. I wish MDs were as well informed.

  8. I have been suffering with acid reflux been taking pepcid couldn’t go with out one day with out it started d-limonene for 3 days with out pepcid symptoms almost totally gone . I see that recommended dosing is every other day. I took 3 days in a row so far going to start every other to see if symptoms stay away this is definitely worth trying

  9. Would you anticipate a negative reaction between digestive enzymes and d-limonene?

    • You may irritate the stomach lining from the digestive enzymes and from the endotoxin die off from the D-limonene, but that would be rare and limonene is cytoprotective of the stomach.

  10. Is there a particular time of day you recommend this be taken? With/without food, etc?

    • Dear Jo,

      I like taking it with dinner, it has a calming effect. I would always take it with food to lessen stomach upset.

      John

  11. John i am hesitant to tru such a large capsule
    I purchased 2 bottles from Jarrow as food often
    gets stuck in my esophagus -is their a liquid
    form of d-limonene or smaller capsule ? I would love
    to try this product as I have constant heavy mucous.
    thanks
    Nancy

    • Nancy – Google the brand Orange Burps. They have smaller softgel capsules. They’re easier to swallow, and you don’t have to take as much at once if you don’t want to.

    • Dear Nancy,

      I recommend Orange Burps now which is a smaller softgel. https://orangeburps.com/

      John

      • Jarrow has recently reformulated their softgels to be smaller and they are now selling a bottle of 120 capules, with 2 capsules constituting a 1000 mg serving.

  12. I notice that Amazon reviews for Jarrow D-Limonene 1000 mg softgels run about 300 positive to 100 negative. Not a bad ratio, but some of the negative reviews speak of serious stomach discomfort, nausea/vomiting, and reflux that is exacerbated by the pills. Any thoughts on why the large divergence in experiences?

  13. Took the 20 day course for gerd and stopping Prevacid 24 after 10yrs of use can i just take it as needed sometimes i feel bloated when i take it reflux is better

  14. I’m getting down to the last few of 60 1000mg d-limonene softgels. I’m not cured, but I’m pretty sure they’ve helped with my reflux. I wonder though, should I buy another container and continue to take them?

    • I would assume it would be safe to take another bottle to see if it helps, but make sure you get the approval of your health care practitioner.

  15. Hey john, I just stopped buy your blog after searching for gerd problems several times, i see you keep posting information regularly, so I’m a little confused, i want all in formation as possible cos i’m really desperate to heal myself, my question is that if i buy your e-book maybe i won’t have to check on your posts daily right? or not? answer me plz

    • Most of my posts are new information that may not be in the book. The book is a good reference and full of good information. Some of it is on my blog and some of it is in the book only.

  16. I live in Canada and have been a follower of John Brisson from the time his first edition of Fix Your Gut came out. My doctor recommended Jarrow Limonene as part of the protocol to get me off Nexium (20 years and many unsuccessful tries.) However, I could not find Jarrow or Enzymatic Limonene in Canada. Jarrow can be ordered through Amazon, but will take some time to arrive. However, with a little searching one can find Limonen-E made by Vita-Aid Professional Therapeutics (manufactured in British Columbia). Just thought I would pass this information along for any Canadians looking to buy Limonene.

  17. What do you think about gelcap VS liquid form of D-Limonene?
    Im thinking about taking organic orange essential oil. (This is D-Limonene, right?)
    Would you suggest one is better than other?

  18. What are side effects of D Limonene?

    • For some it can cause irritation in the esophaugus and cause herx reactions from die off. It rarely can cause breathing issues from aspiration, but for most it is well tolerated.

  19. Hi

    I have been suffering with lpr for the past 6 years, constant lump in my throat and struggle to talk. Been on lansoprazole and that seems to make my throats worse. Will d-limonene, reduce this feeling in my throat or even better get rid of it!

    Thanks

  20. does D-limonene help loose esphogus sphincters? I am desperate. many thanks help please

  21. Hi,

    Thank you for all the useful information on your site.

    D-Limonene…wouldn’t that be considered citrus that GERD and LRP sufferers are supposed to avoid?

    Any clarification is helpful!

    • No, D-limonene is a component of citrus, it is not the citric acid which does the most damage to an inflammed esophagus. D-limonene in studies have been shown to be protective of esophageal tissue.

  22. I have been taking d-limonene for about a year now. No bloating at all and I am a former (no longer) IBS sufferer!

  23. I decided it was time to come off the Omeprezole that I took for decades. After researching the long term effects of taking this stuff, I decided I must stop taking it. Nice how the Dr’s never tell you about the rebound effect and that you shouldn’t take this stuff long term. It has been a very difficult process. The rebound effect of more acid then you ever had before is awful. Now I take Ranitdine 2X a day and the D-Limonene usually twice a day. The D-Limonene is amazing stuff! I don’t know exactly how it works, but it does. I was desperate to find something and after a lot of web research, I found this stuff. Whew! Hopefully, the rebound effect will ease up. It’s been about 6 weeks since I stopped the Omeprezole.

  24. what about the use of d-limonene if you have an ulcer, or feel like you do?

  25. John

    How would you incorporate this with your other protocols? E.g. would you wait until H Pylori eradication?

    Thnaks

    • You could use D-Limonene with any of the protocols, it wouldn’t hinder any of my protocols. The only reason one would’t use d-limonene is if they had any side effects with the supplement.

      • Have you noticed if it causes bloating in any of your clients initially, but goes away after using the supplement for a few days?
