Key observations: A 2-week crossover clinical trial including 20 healthy, physically active, adults found that AG1® supplementation was associated with selective enrichment of key bacterial taxa, including Lactiplantibacillus plantarum, Lacticaseibacillus rhamnosus, and Bifidobacterium animalis. AG1® supplementation significantly improved nutritional adequacy by increasing the total number of micronutrient Estimated Average Requirements (EARs) met compared to placebo. Vitamins A, C, and E were the most common nutrient gaps filled by AG1 supplementation.
