The dosages below are from completed studies on humans or on clinical trials on humans. In general, they represent safe dosages for most people. Please be aware that there is often an exponentail effectiveness. Talking half the dosage may only see 1/4 of the effect. We are not looking at minimum effective dosage, but maximum [safe] dosage used in clinical trials and studies.
If a study has been completed, the dosage will be marked Ineffective or Effective -- depending if statistically changes were reported by the study.
This is not medical advice (see your MD for that). It is a reporting on dosages that some MDs have used.
