AG1 formerly known as "Athletic Greens" is a brand of a daily health supplement in powder form founded in 2010 by Chris Ashenden, a former New Zealand police officer.[1] The product is advertised as a green powder that combines multiple supplements to meet a consumer's nutritional needs.[2] It combines vitamins, minerals, prebiotics, antioxidants, and plant-based superfoods, formulated without artificial sweeteners, and is marketed as supporting overall health and digestive function.[3]
AG1 was formulated in an effort by Chris Ashenden to solve for his health issues which included nutrient malabsorption. Dissatisfied by the available medical options to resolve his ailment, Ashenden sought to create a supplement which would aid in covering his nutritional needs, which eventually resulted in the formation of Athletic Greens; later renamed to be AG1.[4][5]
In December 2021, Athletic Greens hired Kat Cole as President and COO and rebranded as AG1.[6] Ashenden resigned from the company in 2024 after details of his legal misdoings before AG1's founding were made public; Cole became CEO.[7]
Paulie Dery, formerly of Yeti, was hired as CMO in 2024,[8] and Dr. Ralph Esposito as Chief Science and Nutrition Officer in 2025.[9]
AG1 has followed a single product and direct-to-consumer model for many years with focus on one foundational product and has reported a revenue growth of US$160 million in 2021, to roughly US$600 million in 2024.[10] AG1 has operated as a fully remote company on a global scale. The company maintains employees in more than 20 countries, with business operations extending across North America, Europe, and Asia.[11]
Ingredients and nutritional benefits
AG1 offers a daily nutritional supplement in powder form, known as AG1 Next Gen. The product is designed to combine multiple health-supporting elements in a single serving.[12] It contains between 75 and 83 ingredients, including vitamins, minerals, whole-food derived superfoods, adaptogens, and functional mushrooms.[13] The formula includes five clinically studied probiotic strains to support gut health and is marketed as being free from artificial sweeteners, while also suitable for vegan, gluten-free, dairy-free, and ketogenic diet preferences.[14] Each serving of about 12 g (one scoop) provides approximately 50 calories, 2 g of protein, 6 g of carbohydrates, less than 1 g of sugar, and dietary fiber.[15] These are intended to support energy levels, immune system health, gut health, healthy aging, and hormonal and neural health.[2][16]
In 2025, AG1 introduced new flavors such as Tropical, Berry, and Citrus in addition to its original version. AG1 claims to bridge the nutritional gaps that can be found amongst individuals.[17] The product is NSF International Certified for Sport, verifying that it is third-party tested for purity and the absence of banned substances.[18][14] Alongside the main powder, AG1 also markets complementary supplements, including Vitamin D3+K2 drops and an Omega-3 oil, intended to be used together with the flagship formula.[19]
The health benefits of consuming AG1 are found to be considerably vague.[27][26] The scientific methods that are used by AG1 to claim nutritional efforts were criticized by Dr. JoAnn Manson, professor of medicine at Harvard Medical School, as lacking scientific "rigor":
These are very small randomized trials. Just as a comparison, we do large-scale randomized clinical trials of many dietary supplements... For a multivitamin, we did a randomized control with 15,000 participants for 11 years to document that there was, in fact, a significant reduction in cancer incidence when taking the multivitamin compared to placebo ... That's what I'm talking about when I say rigor.[26]
Charlotte Martin, a dietitian and author makes the statement that the amount of individual nutrients that a user absorbs is insignificant due to the addition of a relatively large quantity of ingredients present in the powdered mixture.[26]
Other critics have pointed out that a significant number of AG1 ingredients' dosages are not disclosed on the label as they are considered "proprietary" and that AG1 includes in it exorbitant amounts of vitamins which are in excess of recommended levels; such as 1,100% of the daily recommended amount of vitamin B7 and 467% of the recommended amount of vitamin C.[26]
