Oxalate level of huel?


I don’t suppose anyone could tell me the oxalate level per scoop of huel? Or if not, the brown rice protein content?


Oh God not the oxalate debate…


What about oxalate and cyanide together?


Ooohh… don’t even go there!

You’ll say the iron content is too high next! :wink:

*Edit. Don’t forgot about the arsenic traces…

Shouldn’t this be in the flavour suggestions thread? Very bitter almonds would perhaps please those complaining of nauseating sweetness levels. Huel should try it. I bet the complaints would fall right off.


No clue at all, maybe drop customer services a quick email :slight_smile:

We’ve not had the oxalic acid level of Huel measured. We have had customers understandably concerned about antinutrients before, so I wrote this article.

is it the antinutrient aspects of oxalic acid you were concerned about, or another reason?

Thanks for your reply James. The reason I ask is that I have fibromyalgia, and I have recently come across the idea of a low oxalate diet possibly providing relief from this condition, so I’m wanting to give it a try, but I don’t really want to give up my huel! And despite a couple of the main ingredients being high oxalate, if the quantity per scoop is not too high, the overall oxalate level could potentially not be all that high. (the aim being to keep total Oxalates per day below 100.)

If I could get an idea of how much oats & brown rice protein is in each scoop, then I could calculate an estimated oxalate level. (although I’d have to base it on brown rice, as rice protein has not been tested so doesn’t have a value.) I know this would in no way be accurate, but then I could personally get a rough idea.

I’m sure there are other things in the formula which could be high oxalate, but in small quantities, so hopefully would not add too much to the total level.


Hi @Alisino - I don’t know about the links of oxalates and fibromyalgia, but do be careful of pseudoscience. I do understand you’ll explore every possibility to feel better :slight_smile:

I’m going to see if we can get oxalates tested in Huel - if we can, I’ll organise the test; but I might not be able to report back until 2-3 weeks.

The problem with estimating something like oxalates in brown rice protein, is the data would be unreliable.

That would be great, thank you - I’ll look forward to hearing back then.

I am a sceptical person, so I do certainly approach these kind of things with caution, but I am willing to carefully try such changes just in case they help!

Thanks again.

Hi @Alisino - I’ve looked into this.

It’s not possible for us to check the level of oxalates in Huel because there isn’t any.

Indeed, brown rice protein (and brown rice) have extremely low (if any) levels of oxalates. Reading a bit more since your post, I’m very sceptical of the advice you’ve received.

If you are concerned about oxalates, then Huel is fine.

As far as I know, brown rice is classed as “medium oxalate” & oats vary between medium & high, as measured by the vulva pain institute.

How do they grade ‘medium’ and ‘high’? Is it relative and what do these mean in absolute terms?

I have to confess, this isn’t something I’ve come across before, so I’m not very knowledgeable.

The lab we use (a highly reputable lab), doesn’t test for oxalates as they say they are rarely present in foods.

I’ve been following and also have a concern about oxalates…not for fibromyalgia, but for kidney stones. Many individuals who suffer with kidney stones, me included, produce calcium oxalate stones. A body that produces these will produce them faster when taking in high oxalate foods; ie. spinach, almonds, okra, etc. (as I understand, only plant foods contain oxalates). Any way, I think that people who don’t suffer from issues with oxalates often don’t even realize they are a thing. As a marathon/ultra runner, it would be beneficial to use a product like Huel, but is definitely scary when thinking about producing more stones. As a side note…it is generally understood that taking some form of calcium (milk for me), will cause the oxalates to bind up in the digestive tract instead of the kidney, I can’t give any research proof of this, only personal experience that it seems to be working for me.

I also want to add that oxalates and dietary calcium are very important for most (~70%) of kidney stone formers because they are made out of calcium oxalate. RDA dietary calcium actually prevents stones forming because then calcium oxalate forms in the gut. Otherwise oxalates travel to kidneys and bind with blood calcium there.

Here’s a good paper:

From it:

“Under a low-oxalate diet, even in cases of oxalate hyperabsorption, dietary oxalate contributed only a small amount to the oxalate excreted. The majority of urinary oxalate is then endogenously derived. Even in the case of drastic absorption changes, only small changes in oxalate excretion could thus be expected. The situation is of course completely different under a high-oxalate diet. With supplemented 500 mg of oxalate from spinach, more than half of the excreted oxalate was of dietary origin (D. Zimmermann et al., unpublished data). Under such conditions, the extent of absorption is highly critical for the oxalate excretion.”

For healthy individuals maximum of 200 mg of oxalates per day are recommended. Spinach has very high amount, around 900 mg per 100 g.

Here’s a website listing amount of oxalates in many foods:

This is quite a new topic and measurements are hard because the amount depends e.g. on the soil.


I hope the spinach thing isn’t true, I consume tons per day… Seriously, like I way surpass the figures quoted :frowning:

Congratulations, you’re on a high oxalate diet :slight_smile:
It does not mean anything, but you just have a higher risk and if you start forming stones like crazy, I would start from removing spinach from you’re diet.

I myself am still fighting without proper diagnosis. Got my first on 2/5 after having the worst possible pains eating 300 g of spinach one week ago. And a week before that had kidney sand after soy. Then CT said there’s nothing, next week bam, at least one more. Now on low oxalate diet and just getting sand and hopefully going to a proper doctor who knows more than I do about kidney stones tomorrow. Basically ate everything from the table + huel and co., so not surprised. The doctors on the other hand, should brush up their knowledge.


Could you investigate this? Is interesting to know the level in Huel

Hi @airiartev - I did look into this and, the lab weren’t able to test for the reasons above. The bottom line is, if there are any oxalates in Huel, then the amounts are very low.

Fellow kidney stone sufferer here. Also a Huel fan, but my doctor has advised removing high oxalate foods from my diet. Unfortunately, brown rice is high oxalate (as is stevia, but one could just get the unflavored version).

I would love to find out the oxalate content or at least the volume of brown rice in the mixture.
