In reply to MAOI's and egg white protein powder, posted by Gayle May on August 7, 2011, at 15:58:04
> I was wonderering if the question from 2006 yes 2006 reagrding the safety of drinking protein powder while on an MAOI was ever resolved?I cannot use soy even if I was not on a MAOI ( upsets my stomach) so I was going to use an egg white protein powder. Ineed the extra protein for another condition that I have. I am on 20 mg of Parnate and have been for years Nothing else works

Hi, Gayle. Welcome to the site.
I don't know why you didn't find your answer in the archives, because this has been discussed numerous times, and to my knowledge, always leading to the same concensus opinion. Commonly available protein powders are assumed to be safe.
The pressor amine responsible for the so-called cheese effect is tyramine, which is produced by the decarboxylation of the amino acid tyrosine. This occurs commonly in protein foods that have been fermented, or have begun to spoil. Fresh eggs are safe with an MAOI, so I can't imagine that a dried extract of whole eggs could be a risk to you.
That said, the pressor effect is dose-dependent, so if you remain concerned about it, simply use an increasing exposure to determine your individual sensitivity to the protein concentrate. That's probably good advice for anyone introducing a new and substantial protein source while on an MAOI, as individual sensitivity to pressor amines varies by a couple orders of magnitude (i.e. by 100-fold or more).
