There is a global movement to limit the use of vitamins and herbs at "therapeutic or medical" dosages to the general public. It is called the Codex Alimentarius"

It is mislabeled as "to protect the consumer of deadly dosages of vitamins and herbal supplements" and other false precepts.

I recommend that you join the fight with the Alliance for Natural Health to stop the passing this international law called Codex Alimentarius.

Here is a link on Codex Alimentarius by Alliance for Natural Health.
