Tested for those who test themselves.

We rigorously test our formula for hundreds of contaminants and impurities to guarantee we’re delivering the highest quality nutrients available. And AG1 is NSF Certified for Sport, the gold standard in independent quality and safety certifications.

Third-party certifications

AG1 is proudly NSF® Certified for Sport, one of the most rigorous independent quality and safety certification programs in the supplement industry.

‎

NSF conducts annual audits of our manufacturing facilities, reviews ingredients for toxicology, and ensures AG1 label claims are accurate. Additionally, the organization third-party tests AG1 for over 280 banned substances.

Certificate of analysis

Each batch of AG1 is tested for a panel of quality and purity analytes, including microbial contaminants, heavy metals, allergens, and banned substances. As part of routine testing, we also test for chemical compounds like caffeine and oxalates.


The Certificate of Analysis is a document that contains our testing report and the results based on safe limits and specifications.

Heavy metals

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

‎

AG1 is tested to ensure levels of heavy metals are below the guidelines set by US Pharmacopeia (USP) and NSF International.

THIS INCLUDES:

  • Lead

  • Mercury

  • Cadmium

  • Arsenic

Allergens

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.

WE TEST FOR COMMON ALLERGENS:

  • Gluten (Wheat, Rye, Barley) (<20ppm)

  • Milk

  • Egg

  • Peanut

Pesticides & herbicides

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


Rather than relying solely on our suppliers and our rigorous internal standards, we periodically conduct additional third party testing for over 500 pesticides and herbicides,

INCLUDING:

  • Glyphosate: an herbicide and commonly used weed killer in conventional farming

  • AMPA: a byproduct of glyphosate

  • Atrazine: The second-most commonly used pesticide after glyphosate

Microbes & toxins

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

WE RULE OUT:

  • Harmful bacteria, including Salmonella, E. coli, or Staphylococcus.

  • Molds and yeasts that have been linked to immune disruption.

  • Microbes that can produce toxic substances like mycotoxins and aflatoxins.

Banned substances

Professional and Olympic athletes have relied on AG1 for their nutrition and performance for over a decade. As a product NSF Certified for Sport, AG1 is tested for over 280 substances banned by major sporting organizations to mitigate risks of consuming contaminated, adulterated supplements.

BANNED SUBSTANCES INCLUDE:

  • Anabolic agents & beta blockers

  • Beta-agonists & diuretics

  • Hormone antagonists

  • Masking agents

  • Narcotics/cannabinoids

  • Stimulants

  • Selective androgen receptor modulators

  • Metabolic modulators

  • Growth hormone secretagogues

Residual solvents

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 program, AG1 is tested for all 3 classes of solvents, including acetone and ethanol.

Nutritional testing

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.

Sensory experience

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 flavor.

THE NATURAL FLAVORS IN AG1 ARE DERIVED FROM PLANTS AND DO NOT INCLUDE:

  • Artificial sweeteners

  • Added sugar

  • Erythritol

  • Monk fruit

  • MSG

I’ve always had a hard time choosing the right multivitamin and having to take pills. AG1 has been a godsend for me. My gut feels better, I feel more awake during the day and feel overall healthier and less sluggish.

I Love AG1

I feel so much better since I ditched my daily multivitamin and switched. I have energy. My stomach isn’t grumbling anymore. It gets delivered every month. It really couldn’t be any easier.

Long Time Customer

I have been using AG1 for at least 5 years. It’s much better than taking a multivitamin and it’s got a surprisingly good taste. It’s not bad at all. Their customer service is also some of the best I have ever experienced.
