amygdalin

1. Amygdalin is a cyanogenic glycoside found in the seeds of apricots, almonds, peaches, cherries, and apples. It is known for its bitter taste and controversial history in alternative medicine, particularly as a supposed cancer treatment (often marketed as Laetrile or Vitamin B17, though it is not a true vitamin).

Key Facts

• Amygdalin releases hydrogen cyanide (HCN) when metabolized, which can be toxic in high doses.
• Found in bitter almonds, but sweet almonds contain little to no amygdalin.
• Often marketed under the misleading term “Vitamin B17”, but it is not a true vitamin.
• Laetrile, a semi-synthetic form, has been banned in many countries due to safety concerns.
