The daily value (%DV) builds on the reference dietary intake to create a number for everyone. The RDI for amino acids is set by the U.N. Reference Dietary Intake (%RDI) - The Reference Dietary Intake (RDI) accounts for age and gender.and found on the nutrition labels of most products. Daily Value (%DV) - The %DV is a general guideline for everyone and takes into account absorption factors.Some of the most popular targets include: Setting targets can provide a guide to healthy eating. If you only plan to consume tyrosine, and no phenylalanine, you should double the RDIs.īelow is a list of the top 10 foods highest in tyrosine, for more high tyrosine foods see the extended list of tyrosine rich foods. 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). ( 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. The reference dietary intake (RDI) of phenylalanine and tyrosine is 25mg per kilogram of body weight or 11mg per pound. High tyrosine foods include beef, pork, fish, chicken, tofu, milk, cheese, beans, seeds, nuts, and whole grains. ( 3) Note that many high tyrosine foods also contain phenylalanine and so are not a good substitute. ( 2) People suffering from Phenylketonuria typically take tyrosine supplements since they cannot consume phenylalanine. Tyrosine is conditionally essential since it can be made by the body if a person consumes enough of the amino acid phenylalanine. 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).
