Natural health products containing botanical, agricultural, mineral or other naturally sourced ingredients may require consideration of elemental contaminants.

PBR's documented service capability includes:

  • lead;
  • arsenic;
  • cadmium;
  • mercury

for applicable matrices through a subcontracted inductively coupled plasma mass spectrometry service.

Where Can Heavy Metals Come From?

Potential contributors can include:

  • source materials;
  • soil;
  • agricultural conditions;
  • mineral ingredients;
  • supplier variability;
  • processing inputs.

What Does the Laboratory Result Tell You?

It reports the measured concentration in the submitted sample.

The result must then be compared with the applicable specification and decision criterion.

Ingredient vs Finished Product Testing

Ingredient testing can identify potential problems earlier.

Finished-product testing evaluates the final formulation.

One does not automatically replace the other.

Ask PBR about your matrix, target elements and specification before submitting samples.
