What Is Molecularly Distilled Fish Oil? (with pictures)

Mar 27, 2022 In molecular distillation, a molecule may escape the source chamber on the first or second evaporation. In a traditional still, the molecule may be evaporated and condensed a thousand times or more before leaving the chamber. Molecular stills operate at low pressures, use low or no heat, agitate the surface of the source, and provide a wide ...

What Is Molecularly Distilled Fish Oil? (with pictures)

Mar 27, 2022 The use of molecular distillation addresses all of these concerns and separates the beneficial fatty acids from the undesirable, smelly components of fish oil. Fish oil supplements are rich in healthy fats, such as omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid, commonly called DHA.
