Interesting that the labelling and the website would lead you to believe that tyrosine is the main ingredient; it is, in fact, the smallest portion.
Tyrosine has many metabolic functions, including precursor to melanin, the natural skin pigment. But since it's only in trace amounts (less than the copper content, and copper is only tolerable in trace amounts. More than that, and copper is toxic.)
Since the beta-carotene is the primary ingredient, you can rest assured that it will turn you carrot-orange, including your skin, eyes, and fingernails (it will have the same effect on your hair, but that may or may not be apparent, depending on your natural color.) |
