Thank you for your replies, rtrt and fernly, and thanks for the welcome.
I thought I should reply once more for the benefit of anyone else who might want to know the answer to my question.
Having ordered some Huel, it doesn’t seem that it contains tyramine in dangerous amounts, since there’s a notable
lack of physical symptoms associated with hypertension when I consume it.
It’s typically very obvious when I’ve eaten high-tyramine foods on phenelzine because soon after doing so I develop an awful headache, one of the classic signs of high blood pressure. It’s often been the case in the past week that I’ve developed a headache after eating a certain food that I thought was fine only to discover upon a subsequent investigation that the food is high in tyramine or has a ‘forbidden ingredient’, so my body is clearly quite sensitive to the presence of this substance, although not, it would seem, to the most dangerous degree.
However, headaches have been notably absent when taking Huel, leading me to conclude that it’s probably safe for people on MAOIs, although I should reiterate that I know almost nothing about nutrition and it’s my understanding that individual sensitivity to tyramine varies, so what’s safe for one person might not necessarily be so for another.
