Huel is much thicker than Soylent. It’s the only downside I see. Interestingly, I manage to make it without a blender. I use a bit less water, which leaves more space in the bottle and makes it easier to agitate the mixture. There’s more room inside to “slosh,” which makes it easier to break up lumps. Then I add more water to dilute it.
I see from Is Huel v2.2 too thick? that about half of users think it’s too thick, half think it’s fine. Definitely seems like they went overboard with the gum agents. You can’t please everyone, but the distribution of preferences should be equal between half thinking it’s thick versus thin. I much preferred Soylent’s consistency, if it only weren’t so synthetic.
(I’m on the US version of Huel, which has always used calcium carbonate)
