Do not, I mean do not take the medical advice given in this book!!
I am black and i am a medical doctor.I would have loved for this to be a credible book. However, I am rather alarmed at the science she describes in the book. Mostly were quite not right. Also, medical advice she is giving in telling people to take Tyrosine and Phenylalanine. Not good idea, these amino acid have direct Neuro-modulating effect and should be only taken under medical supervision. Also, telling black people not to take vitamin D, is a dangerous advice, since I personally know that all my black patients are vitamin D deficient, without exception!!. Vitamin D , is a vital vitamin and its not only about skin, but about bones and the immune systems. Please, don't give medical advice, unless you are well informed. That's why we study medicine for a long time.Its not that simple or easy. Namaste
