Vitamin B17, also known as amygdalin, is a compound found in the seeds of fruits like apricots, almonds, and peaches. It is not officially recognized as a vitamin by the scientific community, and its classification as a vitamin is often debated. Some people believe it has health benefits, particularly in alternative medicine. Research on Vitamin B17 has been controversial, with claims that it can help treat or prevent cancer. However, scientific studies have not conclusively proven these claims, and the compound can release cyanide when metabolized, leading to potential toxicity. Always consult a healthcare professional before considering its use.
