Can someone tell me what the distinctions prior to a compound do to function (N, acetyl, L)? I was thinking of adding in L-tyrosine to my stack until I noticed there are different forms of it that might be good possibilites too. I am often confused about how the addition of an acetyl group changes function (like in L-carnitine vs. acetyl-L-carnitine, for instance). Thanks.

N-acetyl-L-Tyrosine, Acetyl-L-Tyrosine, or L-tyrosine?

L-carnitine works different from N-acytl L carnitine, but Nacytle L tyrosine coverts to neurotransmitters the same as tyrosine, just 4-6 times faster, and more efficiently. Some say when people dont respond to L-tyrosine, the respond to the n-acytl form. N-acytl-L-Tyrosine cost 4X more than Ltyrosine, but 100mg of N-acytl-l-tyrosine is going to deliver the same effect of injesting about 800-1,000mg of L-Tyrosine.GET DIESEL OR DIE TRYIN'

ok. thanks so much. is l-tyrosine faster acting than plain tyrosine, such that all the compounds of tyrosine exist on sort of a continuum when it comes to converting precursors to neurotransmitters, or is that not correct?
L-Tyrosine is the common free form version. It's not as efficient as N-Acetyl Tyrosine. This acetylated version is much more stable and much more soluble which tend to make it more bioavailable (aka. better absorption).
Check out the Jarrow branded N-Acetyl Tyrosine. I, myself, will be using one from Cardiovascular Research called Norival. It's a bit more expensive but check it out.The journey of 10,000 miles begins with the first step.
