We’ve built an in-house team of scientists and researchers to stay on top of the latest in nutrition and microbiome science. Every upgrade to AG1 is grounded in real research, which includes our own clinical trials on the efficacy and impact of AG1.

AG1 is certified by both the Cologne List® and Informed Choice – two of the most trusted global testing programmes. These certifications mean AG1 is independently tested for banned substances and meets strict standards for quality and safety, making it a reliable choice for professional athletes and anyone who wants extra assurance from their supplements.

AG1 is regularly tested for hundreds of potential contaminants to make sure it’s clean, safe, and consistent from batch to batch.

We test for:
– Heavy metals
– Pesticides & herbicides
– Microbial contaminants
– Allergens
– Residual solvents
– Over 250 banned substances

We select ingredients your body can actually absorb. That means potent bioavailable, vitamins, minerals and plant compounds, and rigorously sourced bacterial strains – all tested for quality, purity, and efficacy.

AG1 is made to be part of your daily ritual – and that includes taste. AG1 goes through third-party sensory testing to ensure taste and mouthfeel are exactly as expected. Our flavour comes from real food sources, never artificial additives, and is compatible with every lifestyle.

AG1 is:
– Vegan
– Gluten-free
– Free from added sugar
– Free from preservatives, artificial flavours or sweeteners
– Compatible with a variety of dietary lifestyles
