Frequent urination

I’m on Huel 100% at the moment and weeing same/less than normal. But I have cut my coffee down.

Thanks for the information guys :slight_smile: To be honest I wasn’t expecting that any of you would be experiencing this. My suspicion is that I have a condition that is just worsened/intensified by one of the components in Huel. I also suspect the vitamin mixture, more precisely the B6 and C vitamins may the culprit.
I have no dryness issues otherwise and if the colour of urine is of any good indication I am not dehydrated at all. I do regular push-ups and cycle to work (around 10 miles a day).

If you are urinating more, then the water has to be coming from somewhere, so if you’re not dehydrated, where’s it coming from? This makes me think that, due to the Huel, you are actually consuming more water than you think. Even if you do have a condition, the water has to come from somewhere.

Vitamin C is a diuretic, but only at very high doses and its diuretic effect is small. The amounts of vitamin C in Huel are unlikely to be linked to this.

I can’t tell for sure if there is an actual increase in the amount of urine. I can only guess without measuring anything, but it feels like there is no increase at all. Thus this may only be an increase in the frequency of the urge itself, due to whatever reason. My theory is that there is a change in a property of urine that may lead to the same feeling one gets when their bladder is full. Though as I mentioned I will probably have someone diagnose me instead of relying on guesswork.
I also note that I haven’t really noticed this until my dad (having the same effects) has mentioned this to me. Before that, while I noticed some increase in the frequency, I was either not conscious about it or something has changed in the past month or so. Who knows, it may be just an additional side-effect of the Huel with the noticeably changed taste.
Of course I shall report back in case I find out anything. My next order is due for tomorrow, so I can tell immediately if it was only this batch coming from that different producer having this effect or if it’s something more general.

Thanks for the feedback. Keep us posted


I’m urinating more often too. Maybe due to the low salt intake coupled with the increased fluids?

No idea. It happens with each version of Huel too. In the past 2 weeks I tried the new unflavoured/unsweetened and an “old”, so still extra sweet sweetened version I got from a colleague who never finished theirs - they all have same effect.
I have an appointment for tomorrow at my GP, though it will probably take months to see if they can tell me anything smart about this condition (that I think I have) and maybe say something about why and what exactly in Huel makes me pee so much more.

I have noticed that I’m urinating more often and in larger volumes. I suspect that this is down to the 1L to 1.5L extra water a day I’m consuming with my Huel. I’ve never had as big a fluid intake as you’re “supposed” to have (frankly, I find all my colleagues with their 1L water bottles on their desk forcing themselves through 2 a day a touch weird). So I don’t imagine all this extra water is doing me any harm at all.

@theaardvark What colour is it? I remember hearing that the ideal colour is light lemon yellow. If it’s clear, you’re drinking too much. If it’s orange, you’re drinking too little.

I’m pretty sure that I’ve read somewhere that the body requires more water to process protein-rich foods. And Huel contains > the RDA of protein, I think. So maybe it’s something to do with how the body processes the extra protein? No idea if there’s any science behind that. I’ve noticed a slight increase in peeing though, but I do usually follow my Huel with a glass of water too. I’m usually the 2nd or 3rd on this list:


That would be the first thing I consider if it weren’t for the fact that this also happens when I drink only one bottle of Huel all day and eat non-Huel food for the rest of the day.
It could either be something induced chemically or mechanically, I would think. I have plenty of gas with Huel and a slight stress in the lower parts of my stomach (hypogastric region). This feeling I also get when I’ve eaten something that my digestive tract is not so happy processing. My current theory is that this slight stress may lead to slightly swollen intestines, which will push on the bladder, causing the need to pee.
Mind you I have not tried other powdered foods yet, so this may be an issue between my digestive system and powdered food in general, not something in particular to Huel.
And also that I don’t feel particularly bad or worried, it’s just an effect that makes it somewhat uncomfortable to drink Huel, being a major con of the product alongside it’s many pros.
Update on my status: went to the GP the other day, prostate seems fine, urine test started, blood test scheduled.

Thanks for that urine colour chart. I’ve seen it before, but I have saved it this time.

LOL @ “There is no such thing as purple urine”

Same issue here.

Yesterday I was stuck on a long car journey. I’ve noticed an increase in urination frequency since starting Huel two weeks ago. I didn’t have any for the day, so last intake was 14 hours prior. Eventually had to pull over as the urge became so intense. From that point on, I had a constant urge, without actually having much urine to pass. I suspect this caused a UTI, but without the burning while you piss part. So perhaps bladder infection?

Anyone else been having UTI symptoms on Huel? Could just be a coincidence.

Update. Saw doctor. No UTI. No infection. This may just be my body responding to increased nutrition.

How much water should one drink when replacing breakfast and lunch with three scoops of Huel a day?

In theory, you should not take into account the water you consume with Huel as unlike regular food, Huel is entirely dry. Thus you should still drink a lot of water alongside, just as it is recommended otherwise… something like 2-3 litres a day (though I personally would go by the rule of “trust your thirst”)

Then again, I can’t tell how much is the actual water content of the foods that I am eating on average. If I take into account the calorie:water ratio, I would imagine a small portion of chicken and veg plate amounting to around 600 kcals may contain 1-200ml or water tops, whereas a bottle of Huel I make with 150g powder (also aiming for 600kcal) will contain precisely 500ml of water, so easily twice the amount.
This is further supported by the concept that if you were to blend the previously mentioned small portion of chicken and veg you would probably get a resulting paste with something of a lot thicker consistency than your regular Huel - you would probably have to use a fork or spoon to eat that, not just chug it down. OK this is not actually supporting it as I have never tried to blend chicken and veg to check the consistency.

@deggen Do you see anything similar just less frequent before/without Huel?

I am now done with the blood test and will see my doctor in like two weeks. Guess I am not as lucky with receiving a fast diagnosis as you are lol

@zoltan I’ve yet to have a blood test. Could be a prostate problem apparently.

I have been drinking Huel for two weeks with increased urination. No problem.

Problem only started when I stopped Huel for a day and ate crappy food with tons of sugar. Back on Huel today problem persists.

Yes, I think you’ve made a good point here. Yes, most food contains water, but Huel contains significantly more water. Try blending fish & chips or a cheese sandwich and see if they are in any way a drinkable liquid. Even if you were to blend a roast dinner with gravy, it would still likely be too thick.

I think the water content of Huel is the equivalent of food + a moderate amount of additional water. So think of a sandwich plus a small glass of water.

I think if people notice they are urinating more on Huel, they were probably dehydrated before.

Interesting. So it’s more likely to be a reaction to one of the ingredients. Something is causing bladder irritation.

I don’t find having to go to the loo every hour healthy and the effect seems to last throughout the day even if I drink one bottle in the morning. Though this is not based on a controlled measurement, just my and my father’s personal observation.

Today I am doing an experiment, I will try to drink only two cups of tap water (~470ml) alongside 100% Huel (125g x 4 mixed with 600ml water each). I’ll try to measure the “output” as well as frequency.

Could be a food intolerance of some kind:
