What is L-Tyrosine?

L-Tyrosine is a nonessential amino acid that is used by the body to synthesize proteins. The name "Tyrosine" comes from the Greek word for cheese, "Tyros," because it was first isolated from cheese in 1864. Tyrosine is present in many protein-rich foods such as cheese and dairy products, meat, poultry, and fish.

Good stuff

I have been using L-Tyrosine for years and notice a difference in my ability to stay focused and concentrate for sustained periods. I like BulkSupplements the best and that's why I keep buying from them.
