I have recently been prescribed an MAOI called Nardil (Phenelzine), and have to adhere to a strict diet which excludes Tyramine content and high amounts of L-Tyrosine. Failing to to this could result in a hypertensive crisis, stroke and brain haemorrhage.
Tyramine is normally found in aged protein foods (cheese, non-fresh meat & fish etc.) the longer a protein is left, the more L-Tyrosine breaks down into Tyramine, hence making the food dangerous for me.
However I am not sure (and cannot find any information) about whether Whey Protein is a food that has a Tyramine content which could be dangerous. I am concerned because Whey protein is obviously concentrated and processed milk protein, and perhaps during this processing, it steadily builds up a large Tyramine content from the L-Tyrosine breaking down.
Here are the questions I would like to know answers for:
1)What is the Tyramine content of Whey Protein? (if any)
2)Do you know if it would be safe to take Whey Protein while on an MAOI?
Thank you very much for helping me on this, I have already emailed this question to many leading companies (Optimum nutrition, My Protein, Pfitzer, Pharmacy companies and universities) and I have not recieved one reply as of yet, so I look forward to hearing from your responses here.
