We highly recommend you research the use of Colloidal Magnesium on the internet, in books, or speak to a natural health practitioner. Please research uses for Magnesium, Alchemical Science makes high-stability 10-20 PPM (parts per million) magnesium. The strength always varies from batch to batch, anyone claiming a mass-produced Magnesium solution to always be a fixed PPM is perhaps not telling the exact truth.
