Levodopa interacts with Tyrosine. Tyrosine might decrease how much levodopa the body absorbs. By decreasing how much levodopa the body absorbs, tyrosine might decrease the effectiveness of levodopa. Do not take tyrosine and levodopa at the same time.

Thyroid hormone interacts with Tyrosine. The body naturally produces thyroid hormones. Tyrosine might increase how much thyroid hormone the body produces. Taking tyrosine with thyroid hormone pills might cause there to be too much thyroid hormone. This could increase the effects and side effects of thyroid hormones.


I have been weaning myself off of my antidepressant, and L-Tyrosine has played a big part in making it a less painful experience. I take it in the afternoon, so give me a little boost, and so far, it has worked quite well. I'm a fan! -

Details "L-Tyrosine"

I give it 3 stars because I take it with 5-HTP and Mucuna pruriens. Otherwise by itself, it is ineffective for me personally.

Details "Appreciate This Product"

This is part of my daily regimen. In the world we live now, dopamine is very important and it's important to replenish it naturally and not through escapism (TV/Internet/Etc.) Having enough dopa will help you make better choices. I will be taking it for a while to make sure I've fully optimized my brain before doing it on a more intermittent basis.
