Understanding Vitamin B17: What Is It?
Vitamin B17, also known as amygdalin, is a naturally occurring compound found in various plants, particularly in the seeds of certain fruits. Despite commonly being referred to as a vitamin, it is crucial to note that its classification as a vitamin is somewhat disputed among scientists and nutritionists. The term “B17” primarily stems from its promotion in alternative medicine circles and its historical context rather than being recognized in the traditional sense like Vitamins A, C, D, and others.
The compound amygdalin consists of glucose, benzaldehyde, and cyanide. When ingested, it has the potential to release cyanide in the body. This raises considerable debate regarding its safety and efficacy. While some proponents claim that Vitamin B17 has health benefits, particularly in relation to cancer treatment, these claims lack robust scientific backing and have led to significant controversy in the medical community.
Historical Context of Vitamin B17
The fascination with amygdalin traces back to the 19th century. A chemist named Marcelin Berthelot first isolated this compound, and over the years, it gained notoriety as a potential remedy for cancer. The most notable individual promoting its use was Dr. Ernst T. Krebs Jr., who presented amygdalin as a “cure” for cancer under the name laetrile. This synthetic form of amygdalin became widely discussed in the 1970s as an alternative treatment.
However, despite initial enthusiasm, rigorous clinical studies failed to demonstrate its effectiveness in fighting cancer. The U.S. Food and Drug Administration (FDA) and other health authorities have consistently warned against its use due to the risk of cyanide poisoning and lack of scientific validation for its purported health benefits.
The Biochemical Makeup of Vitamin B17
Amygdalin’s structure includes:
- Two molecules of glucose
- A molecule of benzaldehyde
- A molecule of cyanide
When metabolized in the human body, especially in the presence of certain enzymes, amygdalin can break down and release cyanide, which is a potent toxin. The extremely low doses present in foods rarely pose a risk but can still have health implications, particularly with large quantities or concentrated supplements.
Sources of Vitamin B17 in Foods
While the debate surrounding Vitamin B17 continues, it’s essential to recognize the natural sources of this compound within our diets. Here are some notable foods that contain amygdalin:
1. Apricot Kernels
Apricot kernels are perhaps the most famous source of Vitamin B17. Traditionally, these seeds have been consumed in various cultures around the world. However, they also contain cyanogenic compounds, making them potentially hazardous if consumed in large quantities.
2. Bitter Almonds
Bitter almonds contain a significant amount of amygdalin compared to sweet almonds. While bitter almonds are used for flavoring in certain foods, they should be consumed cautiously due to the risk associated with cyanide poisoning.
3. Apple Seeds
Apple seeds do contain amygdalin, but the amount is quite small. The seeds must be chewed thoroughly to release the amygdalin, and even then, a typical serving yields a negligible amount.
4. Other Sources
Additional foods that contain Vitamin B17 include:
- Cassava
- Peach pits
- Plum pits
- Lima beans
It’s crucial to remember that the concentration of Vitamin B17 in these foods is significantly lower than in concentrated supplements, which raises safety concerns.

However, the risks associated with high concentrations or concentrated supplements warrant serious consideration.
It is always essential to prioritize a well-balanced diet rich in recognized vitamins and nutrients proven to support overall health. Consulting healthcare professionals regarding any changes to diet or supplementation patterns ensures informed and safe choices, particularly when exploring controversial topics like Vitamin B17.
In summary, while the idea of Vitamin B17 may intrigue those seeking alternative health solutions, significant caution, and skepticism should guide any exploration of its purported benefits and potential risks. Always prioritize safety and science when making health decisions.
What is Vitamin B17 and why is it considered controversial?
Vitamin B17, also known as amygdalin or laetrile, is a compound that is sometimes categorized as a vitamin, though it is not officially recognized as such by most health authorities. It is found in various seeds and fruits, particularly in apricot kernels, bitter almonds, and apple seeds. The controversy surrounding Vitamin B17 primarily stems from its proposed use in cancer treatment and the claims about its ability to cure cancer, which lack substantial scientific backing. It’s often touted by alternative health advocates, but the mainstream medical community regards its efficacy with skepticism.
The controversy is further compounded by safety concerns. When metabolized, amygdalin can release cyanide, which is toxic in high amounts. Studies examining the use of laetrile in cancer therapy have produced mixed results, leading to its ban in several countries for medicinal purposes.
