This tool helps you feel confident in your purchase, knowing it meets the highest quality standards. What is Know What’s In Your Bottle? Understanding what ingredients are in your supplement and how they’re being tested is important. This is where Know What’s In Your Bottle (KWIYB) comes in. For our vitamins, minerals, and herbs, just enter your Nature’s Way product name, SKU number, or ingredient into our search engine to get a transparent look at the ISO-accredited quality testing that went into your products. Which quality tests are conducted? The quality tests displayed on KWIYB cover a range of quality standards. You will see “tests done on every batch,” which includes extensive testing on every batch of ingredients/raw materials before they go into production, and “tests performed periodically,” which includes additional tests to ensure every supplier’s testing meets federal regulatory and our own high standards. There are three stages of testing. First, we test every batch of raw material we receive. Then, we test the formulas throughout production. Finally, we test the finished product. Quality tests we conduct: Identity testing: Confirms the ingredient listed on the label is what’s in your bottle. This includes non-botanical (vitamins, minerals, acids, etc.) and botanical (herbs) identity testing. Purity testing: Ensures the ingredients contain no unwanted compounds. Potency testing: Ensures ingredients are present in the proper amounts. Composition testing: Ensures all substances 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. What is ISO-accredited quality testing? The International Organization for Standardization (ISO) defines rigorous requirements for quality testing. At our onsite laboratory in Green Bay, Wisconsin, we adhere to the internationally recognized ISO 17025 standards developed by the ISO. ISO accreditation is audited annually and confirms that Nature’s Way lab delivers valid, reliable results and upholds the highest standards of quality and accuracy. Since our lab is onsite, we can maintain full control over product integrity, regulatory compliance, and customer trust.
