Amygdalin, also known as vitamin B17 and associated with laetrile, is a cyanogenic glycoside present in fruit kernels and pulps and has long been proposed for anticancer activity. This comprehensive review critically summarizes available evidence on amygdalin’s anticancer effects and molecular mechanisms, while addressing the need for non-toxic delivery formulations. Results indicate reported activity across multiple cancer types, apoptosis induction, proliferation inhibition, and potential reduction of metastasis, but highlight limited in vivo and especially scarce clinical data.

Amygdalin, also known as vitamin B17 (and laetrile, a synthetic compound), is a cyanogenic glycoside compound that is mainly found in the kernels and pulps of fruits. This compound has been proposed for decades as a promising naturally occurring substance which may provide anticancer effects. This is a comprehensive review which critically summarizes and scrutinizes the available studies exploring the anticancer effect of amygdalin, highlighting its potential anticancer molecular mechanisms as well as the need for a nontoxic formulation of this substance. In-depth research was performed using the most accurate scientific databases, e.g., PubMed, Cochrane, Embase, Medline, Scopus, and Web of Science, applying effective, characteristic, and relevant keywords. There are several pieces of evidence to support the idea that amygdalin can exert anticancer effects against lung, breast, prostate, colorectal, cervical, and gastrointestinal cancers. Amygdalin has been reported to induce apoptosis of cancer cells, inhibiting cancer cells' proliferation and slowing down tumor metastatic spread. However, only a few studies have been performed in in vivo animal models, while clinical studies remain even more scarce. The current evidence cannot support a recommendation of the use of nutritional supplements with amygdalin due to its cyano-moiety which exerts adverse side effects. Preliminary data have shown that the use of nanoparticles may be","cbCaij4BJKJe3Tjy","https://ap.wps.com/l/cbCaij4BJKJe3Tjy","pdf",1407651,17,"English","# Introduction\n# Review Scope and Methods\n# Anticancer Molecular Mechanisms of Amygdalin\n# Evidence Across Cancer Types\n# Safety, Limitations, and Need for Non-Toxic Formulations\n# Nanoparticle-Based Delivery and Future Perspectives\n# Conclusions","[{\"question\":\"What is amygdalin and why is it considered a potential anticancer agent?\",\"answer\":\"Amygdalin is a cyanogenic glycoside (also known as vitamin B17 and linked to laetrile) found in fruit kernels and pulps.
