Editorial Note

The selected depletions information presented here identifies nutrients that may be depleted by certain medications. If you are experiencing any of the signs or symptoms mentioned, it does not necessarily mean you are nutrient deficient. Nutrient depletion depends upon a number of factors, including your:
