Arsenic, Cadmium, Lead, and Mercury…Why Should You Care?

Heavy metals—What are they and why should you be concerned about them? The elements known as heavy metals include arsenic, cadmium, lead and mercury. These elements can be present in the soil that your materials are grown in or found in facilities where your products are produced. These contaminates can pose a health risk to your consumers and could even cause poisoning if they are consumed in high enough quantities. Due to their high health risk, the FDA requires testing for these analytes to be compliant with their GMP regulations. You may be asking yourself some questions regarding this testing and SORA Labs is here to answer them! Some of the most commonly asked questions and their responses are below:
Q: What stage of manufacturing can you test for heavy metals?

  • Raw Material
    • When you test your raw materials, you are more likely to catch a “bad” ingredient before you add it to your blend and ruin your entire batch.
  • Finished Products:
    • Finished product testing confirms that the product meets required standards once all ingredients are blended and no heavy metal contamination occurred during the manufacturing process.

Q: Why Choose the ICP-MS method?

  • There are other methods that can be utilized for heavy metals analysis, however, ICP-MS allows the laboratory to achieve lower detection limits when compared to ICP-OES. This lowered detection limit allows for more accurate and precise data on your product.
  • Prop 65 requires certain limits of heavy metals to be met. Some prop 65 results can be obtained by ICP-OES; however, the serving size becomes a large factor. By using ICP-MS the factor of serving sizes becomes less of a deterrent. We are now able to achieve prop 65 levels on a larger variety of serving sizes.
