Milk Thistle

Silybum marianum (L.)

Extract standardized to contain 80% silymarin

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.

Silymarin (from milk thistle)

The benefits of milk thistle seed are often attributed to its component called silymarin. Analyzing each batch of powdered extract ensures your product contains the amount of silymarin promised on the label.

Identification

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.

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.

Standardized 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.

Solvent residue

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.

Aflatoxins

Aflatoxins are naturally occurring toxins produced by specific mold and fungi species that grow on crops and botanicals, so it’s important to know your products are tested for them. While annual qualification verifies our suppliers’ aflatoxin testing for most ingredients, some raw materials are more susceptible, so Nature’s Way tests every single batch.

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.

Pesticides

The Environmental Protection Agency (EPA) sets safety limits, known as tolerances, for residual pesticides, and the Food & Drug Administration (FDA) requires botanical suppliers to comply. Nature’s Way verifies compliance with these tolerances through annual or periodic in-house testing of raw materials following the standards outlined in USP <561> to ensure safety and quality.

Milk Thistle

The ingredient

The name "milk thistle" comes from the milky-white veins in its leaves and sap that oozes out when crushed. The herb has been used in Chinese and Ayurvedic traditions for millennia. While we use the seeds for our supplements, almost all parts of the milk thistle plant are edible. The roots, young shoots, and leaves can be cooked or eaten fresh.

The majority of our milk thistle is cultivated in the cool and dry climates of Asia where vast, fertile land offers ideal growing conditions for amazing milk thistle.
