Provides a noticeable mood boost. This is a must for anyone with thyroid/adrenal issues. One of the few supplements that actually works. Don't overdo it though. I've found that one capsule taken first thing in the morning on an empty stomach (1 hour before eating anything) is all I need. There is another product from Thorne called Thyrocsin which has l-tyrosine in it, but it was impossible for me to take it on an empty stomach due to nausea from some of the other ingredients.

Thorne research is a good brand and tyrosine is like coffee for my add symptoms

L-Tyrosine,is a precursor to Dopamine a major neurotransmitter in the brain. Thorne is a brand I trust as it has no harmful excipients.

I heard Thorne Research is the best brand there is, so I have decided to pay extra few bucks for the best. Taking it as my thyroid rutine every morning. Have no side effects what so ever from it and my thyroid definitely likes it as well.
Great for increasing alertness and thyroid support

Use this in the morning to help increase alertness. Also helps with my thyroid issues, along with taking iodine. Like this brand because no added unnecessary ingredients.
