I noticed that Dr. D recommends the amino acid Tyrosine (along with Arginine)to Type Os for energy and good mental health. I have read in many places that both DLPA and Tyrosine are recommended for these purpose and that they are interchangeable since DLPA is converted into Tyrosine in the body. In this case, does anybody know why Tyrosine is more effective than DLPA?
