Yep, me too. The recipe I was drinking had a high amount of potassium in it. There isn’t a strict guideline on how much potassium you should consume, so there tends to be plenty of it in soylent or similar drinks/powders (I’m not sure I actually ever checked official soylent, but those available to me at the time) for some reason probably due to manufacturing convenience.
I always figured it was this high potassium content that caused heart problems for some. Gave up on the concept after realising this and the heart issue never going away.
