Explore AG1 Comparisons
Supplement comparisons can get stuck on surface-level details: serving size, flavor, price per scoop, the number of ingredients on the label, and so on. Those details can certainly be helpful, and they still matter, but they rarely tell the full story on their own. Probiotic supplements aren't always easy to compare label to label because testing methods vary across brands. While many brands rely on traditional culture-based methods (CFUs), AG1 uses digital PCR (dPCR), a modern molecular method that provides precise identification and quantification of probiotic strains. AG1 takes a broader approach to Foundational Nutrition. It includes vitamins, minerals, whole-food-sourced ingredients, prebiotics, probiotics, and phytonutrients in one daily serving, with a formula designed to support multiple areas of health at once.* Use these resources to take a closer look at AG1 vs. competitors, understand how different formulas are built, and decide what kind of daily supplement makes the most sense for you.
