Yes, I heard the same information and was taking bitter apricot kernels myself (that's one the best source of B17).
BTW, your hair analysis is a very good indicator of what defficiencies your body has...
The lady who does these hair tests was diagnosed with cancer herself and was given only a year to live so she's done loads of research on this matter, she was taking B17 herself and other things (sorry, cannot be very specific but vitamin B17 was the main thing) - she is alive and helping many people today...
Thanks, bylto
