Testing by the numbers
Half of our 75 quality experts have been with Integrative Therapeutics for 10+ years. Here's what they do every year (numbers based on annual averages).
Tests performed on every product
PURITY testing ensures the formula contains no unwanted components
CONTAMINANTS testing ensures raw materials meet regulated limits for unwanted substances such as bacteria, heavy metals, and residual chemicals
IDENTITY testing confirms the ingredients listed on the label are what's in your bottle
POTENCY testing ensures ingredients are present in the proper amounts
COMPOSITION testing ensures key compounds are present in the proper amounts
-
170+
different raw materials are sourced and tested
-
2,000 hours
are spent reviewing suppliers and material quality
-
95,000 tests
are conducted, all with test methods and data recorded
Certificate of analysis
A certificate analysis (COA) is a quality document confirming that a product has been tested and meets established specifications. Our COAs summarize the laboratory testing performed on finished batches—including verification of active ingredients and confirmation that quality and potency standards are met—providing transparency and confidence in every product we make.
In-house vs. third-party testing
Like many brands, we use third-party laboratory testing. Unlike most brands, however, we also test products in our own ISO-accredited lab. Capable of high-level ISO 17025 testing, our onsite lab enables us to conduct additional tests throughout production and design fit-for-purpose test methods for in-depth analyses.
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
