Can i take tyrosine with sssi's (citalopran)?

Yes, you can: Tyrosine is an Amino Acid that is used to produce noradrenaline and dopamine; supplemental appears to be anti-stress for acute stressors. Citalopram is an antidepressant medication that affects neurotransmitters. It is selective serotonin reuptake inhibitors (SSRI) and no interaction with noradrenaline. It is safe to take both medications. Hope it make sense?

Why do you want to?: Phenylalanine (Phe) is used to make tyrosine (Tyr). Tyr is used to make DOPA which is made into dopamine in neurons. Tyr that doesn't go into proteins or to make DOPA is burned for energy. If you INGEST Tyr, you just need LESS Phe, so excess Phe is burned or broken down & excreted. Unless you have some major dietary, GI or metabolic problem, you may just be wasting your $. Ask your doctor.
