Different foods have different amounts of tyramine. Other foods, besides meats, have tyramine, since incomplete amino acids make up many foods. Plus handling,and preparation may cause the amount of tyramine to be greater. For example. eggs are okay, but egg salad left out, rather than refrigerated, could spoil and even though edible, have much more tyramine than is safe.
I don't know how much tyramine would be in any one dose of the protein powder that's in the supplement, or how often you take it.
However the following is a paragraph from one of Dr. Bob's pages on tyramine interactions:
"The tyramine content of foods varies greatly due to the differences in processing, fermentation, ripening, degradation, or incidental contamination. Many foods contain small amounts of tyramine and the formation of large quantities of tyramine has been reported if products were aged, fermented, or left to spoil. Because the sequela from tyramine and MAOIs is dose-related, reactions can be minimized without total abstinence from tyramine-containing foods. Approximately 10 to 25 mg of tyramine is required for a severe reaction compared to 6 to 10 mg for a mild reaction. Foods that normally contain low amounts of tyramine may become a risk if unusually large quantities are consumed or if spoilage has occurred (McCabe, 1986)."
Given that tyramine content even in the same foods varies from sample to sample, and that protein powders are not regulated, using it could lead to very unfortunate consequences.
