I haven't noticed any difference when taking these.
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.

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.

Great product, great quality and price is very competitive. The service iHerb offer is outstanding, delivery is fast and the whole process is so user friendly.
Works well with a proper combo of 5-HTP & Vitamin B6.
