KEY INGREDIENT(S)
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.
Nature’s Way tests the potency of every batch of raw material to ensure that you receive the amount of calcium per serving that’s stated on the label.
Verifying each botanical genus, species, and plant part ensures your product contains the exact ingredient listed in the Supplement Facts panel and will support the benefit stated on the label. High-Performance Thin-Layer Chromatography (HPTLC) testing provides a detailed chemical fingerprint of the ingredient for comparison against certified botanical reference standards. HPTLC testing is among the best, most reliable methods for authenticating raw materials.
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.
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.
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.
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.
Nature’s Way verifies suppliers' compliance with protective laws like California’s Proposition 65 on a periodic or annual basis. We do this to ensure the raw material meets regulatory standards and won’t expose you to harmful levels of heavy metals, including arsenic, cadmium, mercury, and lead.
Nature’s Way tests the potency of every batch of raw material to ensure that you receive the amount of magnesium per serving that’s stated on the label.
Cholecalciferol
Nature’s Way tests the potency of every batch of cholecalciferol to ensure that you receive the amount of vitamin D3 per serving that’s stated on the label.
Trace amounts of solvents used during processes such as ingredient extraction may remain in the raw materials. Performing USP <467> screening ensures that residual solvents are within safe, regulated limits. Testing every lot of the ingredient ensures it is processed according to Good Manufacturing Practices.
