Third- party certification is a quality focused process that companies who manufacture supplements can sign up to at their own cost and put their products through. All certification programs are voluntary. They are run by external accredited labs with expertise in specific analysis and result interpretation, to assess the presence of selected prohibited substances in products.
Different accredited labs run different programs and have different detection thresholds related to a safe standard. These programs also differ in time points when ingredients or products are tested across manufacturing, and different frequencies on how often they test a final product batch.
So, it is important to know that not all the certified quality assurance programs are the same and they offer different levels of risk mitigation.
That is why it is important to use products that are tested by Quality Assurance Programs recommended by Aspetar.
