Top 10 Foods Highest in Tyrosine

Tyrosine is a conditionally essential amino acid involved in creating brain signaling molecules such as dopamine, and stress hormones like norepinephrine (noradrenaline), and epinephrine (adrenaline). (1)

Tyrosine is conditionally essential since it can be made by the body if a person consumes enough of the amino acid phenylalanine. (2) People suffering from Phenylketonuria typically take tyrosine supplements since they cannot consume phenylalanine. (3) Note that many high tyrosine foods also contain phenylalanine and so are not a good substitute.

High tyrosine foods include beef, pork, fish, chicken, tofu, milk, cheese, beans, seeds, nuts, and whole grains.

The reference dietary intake (RDI) of phenylalanine and tyrosine is 25mg per kilogram of body weight or 11mg per pound. (4) Assuming a person gets half their requirement from each amino acid, a person can then consume 12.5mg per kg or 5.5mg per pound. As such, a person weighing 70kg (~154 pounds) should consume around 875mg of tyrosine per day, and this is the amount used to calculate the reference dietary intake (RDI). If you only plan to consume tyrosine, and no phenylalanine, you should double the RDIs.
