Deglycyrrhizinated licorice root (DGL) extract

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.

Deglycyrrhizinated licorice (DGL)

Nature’s Way analyzes every batch of licorice root to ensure that you receive the potency 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.

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.

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.

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.

GutGard®

The ingredient

Licorice spans cultures and time, from the ancient teas found in King Tutankhamun’s tomb to this day as a soothing agent in dietary supplements. Whether you love or hate the candies it’s most commonly known for, the “sweet root” is used in many foods as a sweetener and sugar substitute.

GutGard® is a clinically studied blend of licorice species that’s rich in flavonoids. Nature's Way uses GutGard® with less than 1% glycyrrhizin to help avoid any potential effect on blood pressure. GutGard® is a trademark of NATURAL REMEDIES PRIVATE LTD., exclusively distributed by AIDP in North America.

Glycine

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.

Glycine

Nature’s Way analyzes every batch of this raw material to ensure you receive the amount of glycine 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.

Heavy metals

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.
