DA = dopamine: Please repost your question with an explanation of how & why you think you don't have enough DA. DA in the bloodstream drives up your blood pressure. DOPA in the bloodstream causes intractable nausea & vomiting. Your brain is walled off from the rest of your system by the blood-brain barrier (BBB), so it's safe from any harebrained notions you may have about monkeying with your neurotransmitters.

Provided original answer
Furthermore: You make tyrosine from phenylalanine. Take tyrosine & your body just needs less phenylalanine. Take phenylalanine & the excess is burned as fuel & excreted. Ditto for tyrosine. Ditto for DOPA. Whichever you take, likely it'll get burned as fuel & excreted as waste. So you'll be able to stand there with your fly open and literally watch your money go down the toilet.

Amino acids: These are different amino acids your body can use to make other amino acids. Most people want to boost their dopamine level in the brain, it is not clear that taking supplements can do this. What is you goal, actually? It would be better to start there.
