Great for increasing alertness and thyroid support

Posted by 4765620060371386981 on Jan 26, 2015

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.

Improves Dopamine

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.
