There is no vitamin B17. The term is inaccurately applied to laetrile, a discredited cancer drug, and amygdalin, the natural substance from which laetrile is made. Amygdalin occurs in the seeds of apricot, peaches, and almonds.
The seeds within apricot pits contain the most vitamin B17. Vitamin B17, also called amygdalin or laetrile, is a controversial natural compound because it contains molecules of cyanide. Cyanide gas is deadly in high doses, but the small amounts of cyanide found in B17-rich foods are essential for health.Vitamin B17 appears in abundance in nature but not in many foods commonly eaten by most people. B17 tastes bitter, so foods or parts of foods that are rich in B17 often are avoided or discarded.yanide gas is deadly in high doses, but the small amounts of cyanide found in B17-rich foods are essential for health.
