Hi Hopiso,
You should realy post and read the R messages a the Vitamin C support forum! Im sure Owen could help advice you also! Vitamin C does not have a toxidty level any excess that the body does not utilize is excreted with in minutes from the body! Whish also flushes toxins out at the same time!The most therapeutic use of vitamins c is to find your titeration levels and reduce the dosage slightly and this dosage would be the best therapuetic dosage for you! On average this would be one gram of powdered vitamin c per ten pounds in body weight!
