Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- AI-generated comics aren't allowed.
- Adult content is not allowed. This community aims to be fun for people of all ages.

i wouldn't necessarily say its a nothingburger but it is hard to judge these things when lead contamination is inevitable
still I think it's more useful to look at average daily lead intake and compare to that baseline instead of arbitrary limits especially as you've noted there is no way to set a "safe" level of lead exposure
for adults this comes out to about 0.3μg of kg body weight - so at 70kg that's 21μg of lead which means that adding an extra 7μg per day via that huel protein increases your lead intake by a third - so it's up to you to decide if you think eating 30% more lead just for the gainz is worth it - i personally don't (especially when you can find powders that don't so this)
That protein shake will probably replace some other kind of food you would otherwise eaten and which will naturally contain some amount of lead, so it's not just a straight up increase on top of your normal daily intake.
But yeah, you're right, avoiding the ones with unusually high lead levels like the Huel powder obviously makes sense.
The way the CR report presents their data is super terrible -- they present it as a per-serving percentage of their arbitrarily-defined concern level of 0.5 µg/day (which by the way is 2.5% of that 21 µg average you cite; unrealistically low) and the serving size they use is whatever the American label of the product reports (serving sizes on American back labels are notoriously arbitrary).
Anyway, the most sensible number I can find in their article is this:
17 ppb is 0.017 mg/kg, which is far below what the EU considers the maximum safe level for any food category, except for infant formula where it's only just below the maximum of 0.020 mg/kg (and exceeds the liquid infant formula max of 0.010 mg/kg, but then these are mostly powders).
According to the report you linked section 3.1.2, 17 µg/kg seems to be pretty closely in line with the average for general foodstuffs. For example dairy has a median lower bound of 2.50 and upper bound of 9.77 µg/kg, while cereals and grains are 11.0 to 28.2.
One funny thing in that EFSA report is this line:
which shows that food supplements (which presumably includes protein powders, but will also include a lot of other stuff like vitamin pills) had, in that study, a median lead content of LB 272 µg/kg and UB 298 µg/kg.
