Iron gluconate

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.

Iron

Nature’s Way tests the potency of every batch of raw material to ensure that you receive the amount of iron per serving that’s stated on the label.

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.

Heavy metals

Every ingredient is tested to meet regulatory standards for heavy metals, including arsenic, cadmium, mercury, and lead. Testing for trace metal levels ensures ingredients comply with protective laws like California’s Proposition 65, and that the supplement won’t expose you to harmful levels of chemicals.

Potency assay

Testing is performed on certain raw materials to measure the potency of a key component. This testing ensures consistency across batches, so you can feel confident that the ingredient matches what’s stated on the label.
