Negative Positive
Title: Folic Acid?
Review: N-Acetyl L-Tyrosine is N-Acetyl L-Tyrosine, so any brand will do, as long as it comes from a reputable company. For some reason, however, Source Naturals (a company I have always considered to be reputable, so I'm assuming this is just an error in someone's judgment that will be corrected sooner rather than later) has elected to add 400 micrograms of folic acid to each 300 mg tablet. Why do that? How does such a large amount of folic acid contribute to the metabolism of N-Acetyl L-Tyrosine? Other manufacturers add B-6, but SN is the only company I can find that adds folic acid. Given that high doses of folic acid are now implicated as a cause of lung, prostate and colon cancers, I cannot fathom why anyone who takes a multivitamin or a B-complex (because most contain at least 400 mcgs) would add to their risk by taking this product.
Is the review positive or negative?
