L-Tyrosine question

I was just wondering if any of you take the supplement L-Tyrosine with your thyroid meds? I read about it in "The Diet Cure" book, and also checked with my doctor who said there was no problem with taking it with my Armour. The book recommends 500-1500mg 1-3 times a day.

Do any of you take this and what amt?

Re: L-Tyrosine question

I Am not currently taking it and haven't taken enough of it in the past to be able to make a recommendation based on my personal experience, but I know that many have reported good results when using is.

Since T4 is a Tyrosine molecule with 4 iodine atoms attached, T3 is a Tyrosine with 3 iodines, T2 is... You get the picture. It is possible that getting some extra tyrosine could be a plus. I have read of some people with borderline cases have reported feeling better on just the tyrosine alone without having to even take thyrod meds.

Re: L-Tyrosine question

Wow, Meep, you blew my mind. I never checked into the chemical structures before. But, while similar, T4/T3 etc. and Tyrosine actually differ by more than just Iodine. My chemistry is a bit rusty, so I don't know if I'm stating this properly but the thyroid molecules also have an additional hydroxy-phenyl group (linked with an ether bond in T4, but without the extra oxygen linkage in T3).

I wonder if the body can synthesize some of its T4 from Tyrosine if it can glean the needed components from other things in the body. Fascinating! I'm so glad you posted about this connection.

Re: L-Tyrosine question

I haven't looked too deeply into it and I know that my post was an over-simplification, but it is well worth researching more deeply, for sure.

Also interesting: Because Tyrosine has to compete for absorbtion with proteins and other amino acids, it is best to take it on an empty stomach an hour before or two hours after a meal, just like with a T4 med.
