B17, also known as amygdalin, is a substance found naturally in over 1200 different foods including the seeds of many fruits (such as apricots, plums, cherries, oranges, nectarines, apples and peaches) and many kinds of raw nuts. Our natural B17 supplement is extracted from apricot seeds. Vitamin B-17 was the name given to the purified form of this molecule by biochemist Ernst T Krebs in 1952. The synthetic form of B17 is called "laetrile" and while it is chemically similar to B17, they are two different compounds.
