FAQ

Frequently Asked Questions

No, they are closely related but not identical. Amygdalin is the natural compound found in seeds. Laetrile is a semi-synthetic derivative, specifically a purified form of amygdalin, often used in alternative cancer treatments.

Yes, in sufficient quantities. Apricot kernels contain amygdalin, which the body can convert to cyanide. Consuming large amounts can lead to cyanide poisoning, which is potentially fatal.

No. Major regulatory bodies like the US FDA and the European Medicines Agency have not approved amygdalin or laetrile for the treatment of cancer or any other disease due to a lack of evidence for efficacy and proven risks of serious harm.

This is a term coined in the 1950s by proponents of alternative medicine to suggest amygdalin is an essential nutrient, which it is not. This classification is rejected by the scientific and nutritional communities.
