Adderall acts by increasing the availability of
dopamine in the brain synapses (areas where neurons interact). This is done by releasing dopamine stored in the brain neurons. Long term use can deplete brain dopamine.
L-
tyrosine is a dopamine precursor that is synthesised by the body in sufficient quantities. One of the actions of Adderall is to reduce tyrosine hydroxylase activity in the brain. This is a key enzyme to convert tyrosine into dopamine. The available tyrosine cannot be converted to dopamine. The availability of tyrosine is not an issue with Adderall use. Also, studies have not indicated any long term benefit for the use of L-tyrosine in the treatment of individuals with
ADHD.
Hence taking an L-tyrosine supplement along with Adderall would not be the answer to prevention/treatment of dopamine depletion in the brain. If you really feel you must; then consider natural food sources of tyrosine - fish, soy products, poultry, eggs, dairy products, lima beans, almonds, peanuts, sesame seeds, pumpkin seeds,
wheat germ, oats, avocados, and bananas.
However, the bottom line remains regular follow-up with your prescribing doctor. It is during these sessions that side effects,including those resulting from dopamine depletion, are monitored and addressed.
