Any known side-effects or allergic reactions know to occur from consuming gurl?

I’m new to Huel and starting my adventure this week. I’ve already had the suggested coffee shot breakfast, which I’ll definitely be repeating! I was just curious if there have been any known cases of side-effects or allergic reactions from consuming huel. I’ve had on and off skin issues since my late teens and was wondering if I might expect to see this aggravate the symptoms?

Many Thanks!
