Why is AG1 introducing this upgrade now?
It’s our belief that a product designed to support nutrition should evolve alongside the research. Since 2010, we have continuously upgraded the AG1 formula, guided by the latest research on ingredients and nutrition, to provide customers with better efficacy, higher quality, and consistent taste. Based on a growing body of research on the role of friendly bacteria in the gut microbiome, AG1 now includes five new gut-friendly bacteria that have been clinically studied: Lactobacillus rhamnosus GG, Lactobacillus acidophilus NCFM, Bifidobacterium lactis HN019, Lactobacillus casei LC-11, and Lactobacillus plantarum LP-115. We also increased the amount of magnesium, offering even more comprehensive daily support.
