Hi,
I thought I’d follow up on this after googling around for some similar symptoms. I started using Huel a week or two ago and I absolutely love it. Recently I’ve been getting nausea, tight chest, hot flushes and palpitations. I thought it was Covid but the tests always come back negative. These symptoms arrived around the same time that I started using Huel but interestingly I also get them if I take a ‘comprehensive’ multi-vitamin (tried it as an alternative). The symptoms go away once I stop using either. So it’s not Huel causing these symptoms in my case, it’s a common ingredient/mineral/vitamin.
As some background I used to have a huge caffeine intake, often chugging drinks like Monster which have relatively high levels of B12. I decided to drastically reduce my caffeine intake and invest in drinking something healthy e.g. Huel. Looks like it’s a process of elimination now but I’ll be focussing on vitamins B (pernicious anaemia etc) and D.
