There are many brands of Amygdalin, Laetrile and or Vitamin B17 on the market and very few contain the quality, purity and structure to be named Amygdalin vitamin b17 according with the definition of Drs. Krebs. We pride ourselves to strive always to provide the best nutritional supplements for our clients, and this is the case of what we call Amigdalina.. The Merck Index lists the physical properties of the chemical Amygdalin vitamin b17. . These properties include, among others, solubility constants, optical rotation, melting points, etc. Unless a product meets all of these specific criteria, it cannot be called Amygdalin (Laetrile-Vitamin-B17). This was our first consideration when choosing Dr. Krebs method of extraction.
