Tests done on every batch

Manufacturers determine the amount and types of testing done on raw ingredients. Nature’s Way goes above and beyond industry standards with extensive testing on every batch of ingredients before they even go into production.

Identification

For non-botanical ingredients such as vitamins and minerals, Nature’s Way uses the test method that has been validated for the specific ingredient. Among these methods are Fourier-Transform Infrared Spectroscopy (FTIR), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and Liquid Chromatography-Mass Spectrometry (LC-MS) for complex ingredients.

Microbiological contaminants

Nature’s Way tests every ingredient for microbial contaminants that can break down ingredients, decrease potency, and degrade a product’s quality. Verifying that ingredients meet regulatory standards for microorganisms like bacteria, molds, and yeasts helps ensure a safe and compliant product.

Tests performed periodically

Nature’s Way performs additional tests to ensure every supplier’s testing meets federal regulatory and our own high standards. Extra testing is especially critical for monitoring higher-risk botanicals.

Vitamin A

Nature’s Way tests every batch of vitamin A to ensure that you receive the potency promised on the label.

Assay

Assay testing is performed on certain raw materials to measure the amount of a key component. This testing ensures consistency across batches of raw material, so you can feel confident that the ingredient matches the quantified amount declared on the label.
