Huel Black side effects?

Hey all - I’m fairly new to Huel. I got my first Huel Black order last month. I slowly started to incorporate it into my day at breakfast, and then after about a wk and a half I started having it for Breakfast and Lunch. Once I started having it at both breakfast time and lunch time I started noticing that I am so thirsty all day long and that my thirst isnt quenched no matter how much water I drink (and I drink a lot throughout the day). I also have a taste in my mouth (almost like a film in my mouth but not (if that makes any sense), and I’m assuming this has to do with being so thirsty) - No matter how much I drink, brush, and gargle it is still there - I’m just curious, is this normal? Has this happened to anyone else? Could it have anything to do with the flavors I started with (Peanut Butter and Salted Caramel). My next order is shipping out on the 20th and I switched to Chocolate and Coffee but I’m curious if this will happen with these flavors as well? I really am enjoying having Huel in my life, I’ve lost 5 lbs this past wk and it has been great, but I dont know if I’ll be able to keep it up if I’m always this thirsty.

I only use regular Huel and not the black so I can’t attest to the differences, but I actually don’t drink anything while on Huel. It doesn’t just keep my hydrated, it keeps me super hydrated. My pee is as clear as the driven snow and frankly I have to go more often than I care to. Granted, I use a 330ml per scoop mixture. I cannot tolerate the recommended 250ml per scoop. It tastes like pancake batter to me, it’s tough to get down. At 330ml and 8 to 9 scoops per day I am getting more than the recommended 8 cups of water a day. Maybe try more water in the mixture. It will go down easier and taste smoother.

I am by no means an expert, but I believe from research that increased thirst can be a side effect of ketosis. It is possible that by using the Huel Black your carb intake is very low and you have entered ketosis. I am not sure if that is accurate, but just based on theories I have read about nutrition. I just started yesterday, so I may end up in the same boat! Best of luck in your personal goals!

Hey @KelliM - welcome to the Huel forum! :grin:

If it’s alright with you, I’d like to learn a bit more! Has this ever happened before? How are you making your Huel? What kinds of things were you typically consuming prior to Huel and what does a typical day look like in terms of foods/drinks?

Hi Charlotte, @Charlotte_Huel Thank you for asking, I don’t mind at all! I mix it with water, except one day I mixed it with black ice coffee. I do 2 scoops with 17 ounces of water. I’ve been having them for breakfast and lunch and I don’t eat or drink anything before my breakfast one. Between breakfast and dinner I drink a lot of water and 1-3 cups of coffee (although as of late it’s only been 1 because I’m so thirsty and coffee doesn’t help at all). After my lunch shake I drink a lot of water until dinner. Dinners can range from anything like Tofu and Falafel to steak tips and chicken. We don’t use a lot of salt as one of my family members has high blood pressure. Usually I have Brussels sprouts, broccoli, cauliflower, green beans at some point during the wk occasionally some rice or bread throughout the wk. One of the days if I’m hungry for a snack I may have a small flour tortilla with crunchy peanut butter or some walnuts and semi sweets (these may be at night around 8ish) - I hope I covered everything. Please let me know if I missed anything or if you have any more questions.

Hey Kelli! Thanks so much for getting back to me - what were you typically consuming during the day prior to Huel and has this ever happened before?

Hi Charlotte @Charlotte_Huel - Bagel, egg sandwich, or smoothie made with Coffee, Frozen cauliflower, banana, chia seeds and almond milk some kind of snack like granola bar or igrapes and very similar dinners to what I have now, and the same veggies but a lot more pasta and bread and unhealthy snacks in between

Hey Kelli, in a healthy person with no prior medical conditions, one thing to consider may be the change in dietary intake and the lower carb intake when consuming Huel Black Edition for two meals in place of the foods you mentioned you were consuming previously.

As you mentioned that you did not experience this when consuming Huel once per day, and it only started after having Huel twice per day, it may be related to the above. Though, if it continues or gets worse, it would be best to check in with your medical provider who would be able to look into this further. Have you tried going back to having Huel once per day and do you find it goes away?

@Charlotte_Huel - I’m sorry for not responding sooner (somehow I missed your reply) - On Friday I actually decided to go to real food for each meal and keep it through the wknd because I couldnt take being so thirsty anymore and I wanted to see if it would help. I ate fairly healthy, most of the stuff mentioned previously and it did seem to improve but not entirely. I still have that kind of filmy mouth and thirsty but not as thirsty. I had cottage cheese for breakfast and I am having a shake now for lunch. I’m drinking my peanut butter that I got in my first shipment but my second shipment is on the way and I’ll see if there is any difference with the different flavors. I dont think I mentioned previously that I’ve had a constant headache for about a wk (including this wknd when I switched back to regular food) but I’m guessing that is part of the dietary change as well. If all continues with these changes I will stop using and will reach out to my doctor (hopefully it doesnt come to that I am really enjoying these shakes) - Thank you for all your help!! I will update you in a wk or so

My recommendation would be to drink at least 8 ounces of water (I drink 16) 30 minutes prior to taking Huel and again 30 minutes after. That should help with digestion as well.

I also experienced this side effect after starting Huel Black. We started intermittent fasting when we started Huel as well, so I wasn’t sure which one was causing me to be so thirsty no matter how much water I was drinking. But based on someone’s comments that we could be experiencing ketosis makes a lot of sense. I’m eating way less carbs, and also doing 16 hour fasts from 8pm-12pm. I didn’t realize that thirst was a side effect of ketosis, but I’ll be looking into this. I will say after 4 weeks of doing this, I do feel like I’m less thirsty now. Maybe my body is leveling out with all the changes I’ve made.

You might be experiences some sort of allergy or intolerance to an ingredient in the mix. You have also changed your nutrition intake too… you might be shedding toxins from your body and so your body is wanting water to help with that. I changed my diet quite severely back in 2012. I purposely took in lots of water to help me clean out toxins as the diet was quite full of roughage and high in nutrition. Once I managed to balance out after a few weeks I found that I wasn’t wanting as much water as I was forcing myself to drink. Just my experience

Glad I came to this forum before ordering.

Thread after thread of adverse side effects has cured me of trying this product.

The ingredients, amounts of each, and ratios seem so arbitrary.

I wanted a low carb version, but not with 40gr of various proteins that makes you have hideous and uncontrollable flatulence or leaves you dehydrated all day.

Are you sure you don’t wish to cram even more oats/fiber/weirdly derived protein?

I mean headaches, extreme gastric discomfort, unquenchable thirst, and cramping into this seemingly miracle product for the damned? Did anyone bother to test this formulation for these side effects?

You know it’s working because it makes you suicidal?

Who in God’s green earth needs 40gr of oats and protein multiple times a day? This is pure madness.

The customers here must be gluttons for punishmet or really into suffering to subject themselves to self-flagellation.

I think I’ll stick with slimfast or ensure. They are effective, low calorie, don’t taste like the color gray, and they don’t glow in dark or make your urine turn into a deadly acid.

Whoah, I dodged a fn bullet today. I was going to order 17 pouches of this “replacement for water torture”.
To the OP, you need to get to a doctor. Maybe your kidneys aren’t functioning normally or you’re diabetic. Eitherway, I wouldn’t need a forum to tell me to stop poisoning myself, I would 86 whatever the thing I am injesting that is killing me.

Best of luck :crossed_fingers:

It’s the fiber that causes the gas. Most Americans aren’t used to a high fiber diet, and Huel can have a period of adjustment as the gut gets acclimated.

Same with the unquenchable thirst…the fiber and oats both absord and help to pass more fluids. Most people don’t drink as much water as they should daily, anyhow, but substitute w/coffee and soda and alcohol. Dieticians recommend drinking half a person’s weight in oz of water daily, more so w/exercise and various activity levels. So figure this and adding a higher fiber diet into the mix, that can lead to headaches (dehydration) and cramps.

Nutritionists generally agree that a person can absorb 35-40g of protein per serving for optimal absorption/benefit. More or less is up to individual diets/goals/nutritional needs.

That’s about all I know. I’m not really a doctor or dietician, I just play one on t.v…

For me, Huel provides a quick, healthier alternative to the crap I was shoveling in my face prior. The minor noxious gases and thirst were nothing more than momentary inconveniences.

You’re here, though. Maybe you’re looking for the same thing.

Have a great day :wink::+1:

I don’t tolerate high fiber well. If I eat 2 fiber one bars it literally ruins my day wreaking havoc causing gas, cramps, and bloating and that’s no where near 40grams of fiber. This company has combine both way too much fiber in the form of oats (could you find a more pedestrian/cheap ingredient?) with 40gr of rotten-egg vegetable protein. From what I read nobody likes the taste or consistency and it takes forever to begrudgingly finish one cup of batter-like substance. Do you people crave negative attention and think meal time should be torture for both yourself and those around you.

Nothing about this product sounds healthy, or advisable to consume.
Hell, you could replace the oats with sawdust and I bet it digest better, have higher nutrient value, and save the company the cost of one of its major ingredients.

To the creator of this product. I think you’re a genius, albeit a sadistic one at that.

Props for convincing so nany rubes that no pain no gain should apply to digesting this concoction and that healthy should be a miserable experience.

Hell of a cult you got here

I’m Audi5000


And you haven’t even tried the product

That’s one heck of a strong reaction to…nothing

Do you let everyone else dress you?!
Do you let everyone else make your decisions for you?

Probably not

Some people, more of the vocal minority, that are coming here to highlight issues with the product because they want to see it improve in whatever manner. The satisfied consumers, like myself, pop in to offer recipes and advice, and don’t have much of anything negative to say. Just to make suggestions on packaging or serving size, new flavors, new products, etc.

Get a friend or relative to go halfs on a bag with you and find out for yourself if this is a product for you. It’s helped many others manage weight, eat healthier, and have more energy/better sleep.

When you begin your reply with ad hominen attacks you lose what little credibility you might have started with. It’s plain to see your empty hand while you bluster like you have a fullhouse. Either add to the discussion with substantive answers based in fact or silence your tongue entirely for you remove all doubt by everyone here you are of no person of consequence to take seriously.

Good days

nachosalad78: Don’t feed the trolls.

Atlasbot: You ought not call every who’s ever bought Huel a rube and then get butthurt about ad hominem attacks. If you don’t want to try it, fine. No one needs a monologue on your decision.

It’s a free country for the moment. Since when is questioning something about a product, verboten? At least I’m on topic, vyiu add nothing to the debate. If I can spare one person from drinking this stuff then all the better. If you think digestive distress, death farts, and saving money by avoiding real food that amazingly doesn’t have these negative side effects in abundance are positives, then by all means, fart your brains out. I bet you think the negative side effects are a feature, a benefit, and proof it’s working. The proper word to describe you is a rube. Only the rube would self-identify and get defensive. Have a wonderful day drinking that stuff, you’re must be so enlightened.


It IS a little fun sometimes…for a bit

Point taken. Why I decided to stop responding.
