Our Members Asked:
Why are vitamins and minerals labeled as "hazardous" in safety data sheets, yet they are used in supplements?

Answer:
Vitamin and mineral raw materials used to make supplements are purchased by manufacturers in highly concentrated or "pure" forms. Exposure (by ingestion, inhalation, or contact) to even small amounts of these raw ingredients can potentially be dangerous to workers during manufacture, so safety sheets exist for each ingredient to provide information about hazards for each ingredient and how it should be handled.
However, the ingredients are generally much safer once they have been made into dietary supplements in which they are presented in lower doses and, often, mixed with other ingredients that reduce their concentration.

July 03, 2024As a Californian, I sometimes see supplements marked with Prop 65 warnings. Is this a different issue?
Please see our article about California Prop 65 warnings on supplements https://www.consumerlab.com/answers/why-does-my-supplement-have-a-warning-label-from-the-state-of-california/cancer-warning-on-labels/.
