Common questions
Does it work every day?
Studies show benefits mainly under stress, lack of sleep or cold, not as a daily boost.
Can I take it with caffeine?
Yes, but start low.
Is it the same as N-acetyl tyrosine?
NALT is often marketed as better absorbed, but plain L-tyrosine raises blood levels more reliably.
