Heartburn / Bloating Anyone?

@SerMeltbeg interesting. I’ve just checked and gluten could be the cause. See here (please note: I don’t recommend these sources, so it might be worth researching more) - https://www.glutenfreesociety.org/acid-reflux-linked-to-gluten-intolerance/


The cause of heartburn is multifactoral and could be linked to any number of things. If you don’t get heartburn with other foods, but do with Huel, can I make some suggestions?

  1. Drink plenty of water through the day, not just what you use in Huel. Indeed, drink after Huel.

  2. Don’t have too big a portion of Huel in one go - maybe 2-3 scoops max.

  3. Make sure you’re sitting upright when consuming Huel; no slouching. And don’t do too much activity for 30 mins after drinking Huel.

  4. Avoid NSAID like ibuprofen, etc

I find that I sometimes get very mild heartburn if I have my Huel thicker. Maybe the answer is to water it down more?

I’ve just started Huel today and I understand exactly the “threat of heartburn”. Coincidentally this is exactly the same feeling when I eat porridge, so I’m assuming its the oats. I don’t believe I’m gluten intolerant and generally water afterwards takes it away. p.s. I’m using 3-4 scoops of U/U.

I am prone to heartburn and have signs of gerd. This has decreased noticably since starting huel (into my third month now), so I’m actually very very pleased with huel in this regard. One factor may be that since huel is giving me sustained and more even energy levels during the day, I am drinking two cups less coffee than previously, and coffee can be a trigger.

I’m new to Huel and but after a few days I started experiencing heart burn.

After a week I switched from Vanilla to Unsweetened but it’s been another week now and no change though it is a bit milder. It’s a shame as in just 2 weeks I lost 2.5kg but I’m dreading the inevitable so I’m close to giving it up. I will experiment with blending it with almond milk and have also cut the portion size to 60g from 120g. Also will give this a go

For what it’s worth I can eat endless porridge without issue but powdered drinks including most protein drinks give me heartburn. Even buttery stuff like croissants don’t really cause me grief.

Lastly, for what it’s worth I first developed heart burn when a) I got fat b) fish oil supplements. Obviously b) is no longer an issue as I quit them sharpish and a) isn’t really a problem as long as I avoid eating lots of buttery foods / protein shakes (though generally vegan protein shakes aren’t an issue - just Whey).


I get a lot of heartburn/reflux and have symptoms of GERD. Can’t say I have any problems with Huel though, quite the opposite in fact. I’m drinking the unflavoured version for about 80-90% of my food intake and have had the least trouble with acid in a long time… it comes and goes in periods, but huel isn’t provocative in my case.

I too have been having mild heartburn with Huel but I’m just starting out with one meal a day so it might be other factors, I’ll keep playing but I do know if I take on a lot of sugar that it causes it.

Interesting point about taking on more water, I’m inherently bad at this…

***Update, no heartburn with the gluten free Huel! Hopefully, this will remain an option

Found out it was Bread and carbs giving me heartburn. On a Keto diet and no heartburn in 2 weeks. I want a Keto diet version on Hule badly.

I had heartburn when using the sweetened huel. I think I went through 2-4 bags of that. I then tried the unsweetened with strawberry flavour which uses stevia and no more heartburn.

The unsweetened is also far easier to mix for some reason and has no lumps. It isn’t as thick. The flavour is not as nice as the sweetened but I prefer not having heartburn.

Is it a coincidence or something to do with the sweetener in the vanilla version?

I get indigestion and heartburn after huel, too. I gave up porridge for the same reason years ago. It’s sad, as in all other respects I’m keen to increase my huel meals, but the acid stomach is really uncomfortable. I get this with the sweetened and unsweetened versions. I have not been able to order the gluten free version as it is out of stock.

Think gluten free is back in to be honest

Thanks JJMC. I did have a quick check after posting and noticed it was in stock this time. I might try it and see if it suits me better.

I too am experiencing this “threat of heartburn”.

I’ve been using Huel since around June, so 3 months, only replacing breakfast Monday to Friday. I never, and have 99% of the time never, experience heart burn or this sensation of “threat of heartburn” before. It definitely begins shortly after consuming Huel. I’ve also never had to be gluten aware, so not convinced it’s gluten to be honest.

I usually have vanilla Huel with plenty of water, 2 scopes, blended, and usually a banana in there too. At the beginning I didn’t find I had this heartburn sensation, but it’s becoming more frequent and regular. I think I’m going to try the Gluten free version and see if I notice any difference.


I have the same symptoms as the others. No heartburn whatsoever on normal diet, but as soon as I have a Huel lunch, within 30-60 min, start getting that heartburn like acid feeling, like it’s going to repeat on me. It’s 100% the Huel (sweetened, no flavour sachet), as it occurs every single time, within the same time frame. Maybe my body is used to needing way more stomach acid and it over produces it, as Huel is much easier to digest than processed food?

How thick are you making it?
How quickly do you drink it?
Any previous issues with gluten sensitivity?

Did you tried that Vainilla version to check if the heartburn came again?

I like your thought, could be that one

Hi, I’m experiencing the same heartburn symptoms. I didn’t in the beginning but recently am getting heartburn an hour or two after consumption. I was disappointed to find the same with the new mix. I’m giving it another go with the different versions and have ordered the gluten free, flavoured, unflavoured and unsweetened bags to see which if any work.
