I’m not OP but I’m wondering if perhaps they are mixing up ingredients with nutrition facts or just marketing content?

Here are screenshots from a mix I was looking at just last night. Chloride is listed as one of the electrolytes, and it’s listed separately in the nutrition facts. But in the ingredients it’s just “salt”.

I’m just speculating though.

Edit: TIL cropping images then hitting “copy and delete” to close them does not actually paste a cropped image on my new phone. That’s annoying.
