Laetril, also known as B-17, is a chemical compound related to amygdalin, a natural substance found in the seeds or pits of fruits like apricots, bitter almonds, peaches, and cherries. It is sometimes called vitamin B17, but it is not a true vitamin or an essential nutrient. Laetril is often promoted as a natural or alternative cancer treatment, but it is not part of standard cancer care and is not approved by medical authorities such as the U.S. Food and Drug Administration (FDA).
Some people with cancer may look for alternative treatments like Laetril, hoping for options beyond standard care. It has been promoted by certain clinics, authors, and patient communities as a way to fight cancer, boost the immune system, or detoxify the body. However, scientific studies have not shown that Laetril can treat cancer or improve outcomes. In fact, it can be harmful because it may release cyanide, a toxic substance, when broken down in the body. Using Laetril instead of proven treatments may delay effective care and increase health risks.
You might come across Laetril under different names, including B-17 or vitamin B17. It may appear in books, websites, patient forums, or from people promoting alternative medicine. Some clinics or practitioners may offer it as part of detox or immune support programs. It is important to know that these claims are not supported by reliable scientific evidence. Hearing about Laetril does not mean it is recommended or safe. If you hear about Laetril, it’s a good idea to discuss it with your healthcare provider to understand the facts and risks.
Because Laetril is sometimes called vitamin B17, people may mistakenly believe it is an essential nutrient or a proven cancer treatment. This is not true. It is chemically related to amygdalin, which also carries risks of cyanide poisoning. Patients often ask their doctors about the safety and effectiveness of Laetril, and it is important to have open conversations to understand the potential harms and lack of proven benefits.
Laetril can release cyanide in the body, which is poisonous and can be life-threatening. Because of this risk and the lack of evidence supporting its use, Laetril is not approved for cancer treatment in the United States or most other countries. Using Laetril instead of proven cancer treatments can be dangerous. This information is meant to educate and should not replace medical advice. If you are curious or concerned about Laetril, the best step is to discuss it openly with your healthcare team. They can provide reliable information, explain current research, and help guide you toward safe and effective treatment options that fit your diagnosis and goals.
