Understanding B-17 (Laetrile): Discovery, Uses, Food Sources, and Safety

Understanding B-17 (Laetrile): Discovery, Uses, Food Sources, and Safety

Hi, I'm Doug Krussel from K3 Nutriments. Today, I want to shed light on a contentious topic in the world of nutrition and alternative medicine: B-17, also known as Laetrile or amygdalin.

This naturally occurring compound has sparked debates due to its purported health benefits and potential risks. Let's dive into the fascinating story of B-17, its uses, food sources, and safety.

What is B-17?

B-17, or amygdalin, is a compound often mistakenly referred to as a vitamin, though it isn't officially recognized as one. Commonly found in the seeds of certain fruits, amygdalin is sometimes marketed under the name "Laetrile" and promoted as an alternative cancer treatment. However, it has no known nutritional role or biological function similar to any B vitamins.

Discovery and History of Laetrile 

Amygdalin was first isolated in 1830 by French chemists Pierre-Jean Robiquet and Antoine Boutron-Charlard. It gained significant attention in the 1920s and 1950s when it was marketed as Laetrile, a purported cancer treatment. Despite its promotion, Laetrile remains unapproved by the FDA due to controversies and lack of scientific support for its efficacy in cancer treatment.

How is B-17 Used?

Laetrile has been primarily used as an alternative cancer therapy, especially outside the United States. Proponents claim it targets and kills cancer cells, though scientific evidence for its effectiveness is lacking. Typically, it is administered orally in tablet form or through intravenous injections.

Food Sources of B-17

B-17 is found in the seeds of various fruits and some other plants. Key sources include:

  • Apricot seeds
  • Apple seeds
  • Bitter almonds
  • Peach pits
  • Plums
  • Cherries

These seeds contain amygdalin, which metabolizes into cyanide, a potent toxin, within the body.

Safety and Risks

The safety of B-17 is highly debated. While some natural health advocates tout its benefits, mainstream medical authorities warn against its use due to the risk of cyanide poisoning. Symptoms of cyanide poisoning can include:

  • Nausea and vomiting
  • Headache
  • Dizziness
  • Liver damage
  • Severe cases can lead to death

The FDA has not approved Laetrile as a treatment for cancer or any other medical condition due to a lack of evidence supporting its efficacy and significant safety concerns.
