Talc as ingredient in dietary supplements

Always read lists of active and inactive ingredients on the labels of dietary supplements. This is especially important for people with food allergies -- such as corn and soy.

On reading the ingredient list of my supplement label, I came across talc. Isn't talc quite a dangerous substance to be taking every day, especially in the form of a nutrition supplement?

You are probably confusing talc with face powder or similar personal products that are not a pure substance and contain ingredients that might be toxic to ingest.

Pure talc is finely powdered hydrous magnesium silicate and is used as a filler and excipent for pills and tablets. It is also used for dusting tablet molds.

Nutritionally it is nothing more than a small source of dietary magnesium and silicon -- both of which are valuable. Breathing it chronically into the lungs, however, can lead to problems.
