The Green Drink Scam: Is AG1 Worth the Buy?

Green drink ‘superfood’ powders have taken the US by storm with the supposed ability to act as a multivitamin, a multimineral, a prebiotic, an adaptogen (i.e. foods that help people respond to stress, anxiety, etc.), and the list goes on. AG1 is one of the most well-known of these ‘superfood’ powders, but it’s extremely costly with a monthly subscription costing 79 dollars.[1][2] Are these ‘superfood’ powders truly beneficial or another fad?
AG1 is a 3rd Party Tested Drug, meaning that the product is certified via an independent organization. AG1 is said to be tested by NSF International, an organization that does annual checks of sanitation and safety of food, water, and consumer products.[6] Therefore, AG1’s product is not tested for effectiveness, only that it meets the company’s safety standards. Still, the fact that AG1 is certified by NSF makes it safer than non-tested options such as Bloom Greens.
Despite being only 3rd Party tested, AG1 still is transparent with its ingredients if one is willing to research what is listed. The ingredients are publicly listed on their site. AG1 additionally posted some of its own peer-reviewed studies about newer ingredients. There is proof that AG1 has shown to change a human’s digestive and intestinal genome through probiotics in the product. The phytochemicals provided by AG1 have been proven to change the microbiome from studies done on mice as well as in vitro studies, in some cases decreasing the biodiversity of certain groups of the microbiome but increasing in others.[5]To be sure of AG1’s effectiveness and safety, more research must be done preferably from multiple unbiased sources.
The probiotics for AG1 primarily come from apple fibers, inulin and probiotic bacteria, Lactobacillus acidophilus and Bifidobacterium bifidum along with other probiotics used and studied, (e.g. faecalibacterium prausnitzii, Waltera intestinalis and Arthrospira), have been shown to aid in anti-inflammation, and digestion in model studies but should be taken with a grain of salt.[1][4][10][11][12]This shift in biodiversity through these probiotics has yet to show any favorability in humans, as the only studies available to the public, seem to only to be an in vitro study based on colonic activity in a human[5].
Nutrition is a fairly new concept, which is why any vitamin, health food or health fad should be taken with a grain of salt. Still, it is undeniable that micronutrients are required for a healthy, functioning body. This is why milk is fortified with vitamin D and salt with iodine.[7] AG1 has been shown to be more effective for certain minerals such as Magnesium, Calcium and Zinc than a supplement tablet, but when it comes to the bioavailability and bioaccessibility, certain micro vitamins such as Magnesium, Calcium and Zinc would increase anyways due to the increased surface area a powder brings compared to a tablet.[8] Other nutrients incorporated such as folate, vitamin B12, vitamin E, etc are essential for a person to stay healthy but, most people don’t actually need them form a supplement as their diet is more than adequate.[3]
Taking too much of certain micronutrients could be dangerous. For example, high doses of calcium can lead to body aches, digestive issues and kidney problems. The vitamins and minerals in AG1 are over 100% of the recommended daily value for a 2000 calorie diet.[3] A micronutrient is called a micronutrient for a reason. Rather than supplements or vitamins, it would be more optimal and healthier to try and get these micronutrients from one’s daily diet.
So is AG1 a scam? Yes and no. There is proof that the drink can act as a multivitamin and possibly remedy nutritional deficiencies. Unfortunately, AG1 is too expensive for most people who would need the drink.[8][9] Rather than a superdrink, it may be cheaper and safer to go with a multivitamin approved by USP, to get the boost of the certain nutrient you need without messing with your body’s delicate biogenome.
