One thing that has disappointed me is that the headaches issue has not been adequately addressed. A significant number of people have complained that Huel gives them headaches, but the Huel team seem quite dismissive of this, saying it's unlikely to be Huel.
I've been experimenting with various combinations lately - flavoured, unflavoured, with extra salt, etc. I'm still not totally certain what the causal factor is. The confusing thing is, adding extra salt does seem to help, but not completely eliminate the headaches, so maybe there is more than one factor at play here. It could be the lack of salt PLUS the sucralose.
I mean, you only have to search "sucralose headaches" in Google to see that it has a history of causing headaches in some people. Unfortunately, it's a similar story with stevia.
But it is causing me to now start looking at alternatives, and speaking as a very long-time user of Huel that's a great shame.
I love the taste and convenience of Huel, I love the concept and the philosophy, and the Huel team are great (apart from their handling of this particular issue). The headaches are not bad, only mild, but time has come for me to properly address this for myself. If I find an alternative product that provides something similar to Huel but without the headaches, I'll be switching, sorry.
