Discover the quality testing and more behind your herb, vitamin, or mineral.

✔ PURITY testing ensures the ingredient contains no unwanted components
✔ POTENCY testing ensures ingredients are present in the proper amounts

✔ CONTAMINANTS testing ensures raw materials meet regulated limits for unwanted substances such as bacteria, heavy metals, and residual chemicals
The Nature’s Way Laboratory is accredited to the ISO/IEC 17025:2017 standard.
Nature’s Way has sourced ingredients from partners around the world since 1969. So, many of our relationships are well-established. Yet, we require every raw material to come with a certification of analysis to meet our elevated standards—and still test every ingredient batch we receive.
Many brands that claim to use third-party testing for unbiased results don’t have an ISO-accredited lab capable of performing high-level ISO 17025 tests onsite. Nature’s Way does. Not only does this allow us to perform the tests mandated by federal regulations, but it also enables us to conduct tests from start to finish. First, we test every batch of raw material we receive. Then, we test the formulas throughout production. And finally, we test the finished product.
Owning an ISO-accredited lab also:
✔ ensures the tests are performed by scientists with a deep understanding of dietary supplements
✔ allows us to design additional, fit-for-purpose test methods to ensure consistency across batches
✔ enables us to perform additional testing on ingredients known to have a higher risk of contamination, misidentification, or inconsistent potency
different raw materials are sourced and tested
are spent reviewing suppliers and material quality
are tested to ensure ingredient identities, potency, purity, safety, and consistency
are conducted, all with test methods and data recorded
