The issue here is that even in the quotes you managed to find, the message seems to be Huel is already well balanced and any further upgrades would be akin to a placebo.
James literally said that there would be zero benefit other than making a few people happy
Tim was talking about why Huel is not organic - is there any particular reason why it would be objectively beneficial if it was?
And the fact that price is a factor doesn’t mean that higher price point necessarily = a higher level of health benefit
speaking of which, your idea of a premium version “maximising health” is just vague nonsense unless you’re going to suggest a particular ingredient for a particular benefit.
Sorry if this comment comes across a bit harsh, I’m not meaning to be cruel, I just think that short of cashing in on some superfood trend (goji berry and kale Huel, any takers?) or catering to specific necessary dietary requirements (e.g. veganism and allergies, both of which Huel is near perfect on already) there’s not really anything sensible that can be done to maximise the health benefits of Huel.
Unless maybe they go full on artisan and bring out “Huel with stone ground oats and hand milled pea protein powder”
