AG1 is tested for those who test themselves

AG1 is certified by both the Cologne List® and Informed Choice – two of the world’s most respected independent programmes for dietary supplement testing.

These certifications confirm that AG1 is regularly screened for more than 250 banned substances, including stimulants, narcotics, diuretics and masking agents – helping ensure it’s safe for both athletes and everyday users.

But it goes beyond banned substance testing. The Informed Choice quality seal also means AG1 is manufactured in facilities that meet strict international quality and safety standards, with robust systems in place to prevent contamination and ensure consistency – batch after batch.

With our strict specifications and extensive testing range, AG1’s quality testing exceeds industry standards.

Every batch is rigorously tested for microbiological purity, stricter than statutory heavy metal limits, allergens and other contaminants. In addition, AG1 is annually tested for an even wider range of contaminants like over 500 pesticides, herbicides and other harmful substances.

The Certificate of Analysis (COA) is a document that contains a summary report of all independent testing done on AG1 by third-party ISO-certified labs. The CoA indicates whether the tests passed the legally established safety limits, or the sometimes even stricter limits set by AG1. The actual measured values can be well below.

Anything that comes from the ground, including fruits, vegetables, and even drinking water, has the potential to naturally contain some heavy metals.

To ensure safety, AG1 is regularly tested for heavy metal levels in accordance with the limits set by the European Commission in EU Regulation 2023/915.

We do not formulate with wheat, dairy, egg, or peanut-containing ingredients. Plus, our manufacturing facilities adhere to strict allergen and validated cleaning protocols, to reduce chances of cross-contamination.

Chemicals used in agriculture can disrupt the gut and immune system, decreasing or even blocking nutrient absorption.

We select our suppliers based on strict internal standards. In addition, we regularly carry out independent testing for pesticides and herbicides – to ensure our requirements are met and that the limits defined by the European Commission in EU Regulation (EC) No 396/2005 are observed.

Microbial testing is crucial for ensuring AG1 is safe to drink on a long-term daily basis.

Professional and Olympic athletes have trusted AG1 for over a decade. To reduce the risk of contamination or adulteration, AG1 is independently tested for 250 banned substances as part of both the Cologne List® and Informed Choice certification programmes.

These programmes focus on substance classes most commonly associated with contamination in supplements, including:

Residual solvents are volatile chemicals that can result from processing procedures such as extraction of plant parts and purification of ingredients. While testing for residual solvents was initially developed for pharmaceuticals, as part of our quality, AG1 is tested for all 3 classes of solvents, including acetone and ethanol.

AG1 tests for nutritional content to ensure that the amounts stated on the label are what you get in the product. Nutritional testing is vital to ensuring the efficacy of the formula, and that you receive what you are paying for.

Taste is an obsession of ours. Every batch of AG1 undergoes a systematic evaluation of sensory characteristics like aroma, taste, mouthfeel, and aftertaste. We conduct a science-based sensory testing program with a third-party to ensure the consistency of the AG1 flavour.

The best part? The flavour of AG1 comes entirely from natural ingredients – with no artificial flavours or sweeteners.
