Please think with your own brain!
Don't be fooled by their quoting of "English and French" scientists!
I have surfed on Google, the most power searching engine for "Vitamin X" and couldn't find any clue as what they boasted. (I know both languages)
BTW, if something is so marvelous and has been formally studied, why you only heard it until nearly today???
The person are said to be a Chinese, why our book didn't write it down? ONly English and French scientists are interested in it???
SAD, so sad to see people fooled by such low level joke!!!
