Determination Of Human Effect Levels Of Nutritional Supplements

Insufficient data are available to determine human effect levels of nutritional supplements, and attention should be paid to the use of appropriate techniques to better identify and quantify these parameters, such as appropriate and sensitive exposure/effect biomarkers.

Nutrient requirements and toxic effects of excess vary by life cycle, such as during pregnancy
