“I was first introduced to AG1 five or six years ago by my nutritionist. He knew how hard I worked, and I've used it every day since. It's one scoop in water first thing in the morning and you know you're getting what you need for the day. It gives me peace of mind to have something that's simple and trusted.”

“I'm really particular about what I put inside my own body. And I'm very particular with what I recommend to the public. The list of things I tend to recommend is actually pretty short, but AG1 is absolutely on it.”

AG1 is clinically shown to enrich the gut microbiome.ᵃ⁻ᶜ
We tested whether the bacterial cultures in AG1 could survive the gastrointestinal tract – only then can they become part of the microbiome. The result: they reach the gut alive.
AG1 helps improve key nutrient levels within 3 months.ᵃ
In a clinical trial, we examined whether the nutrients in AG1 are not just absorbed but also effectively utilised. The result: AG1 made a measurable difference compared to diet alone.
Key nutrients in AG1 were shown to be quickly and easily absorbed into the body.ᵈ
Nutrients only work if your body can take them up. Our clinical research confirms: AG1 delivers essential nutrients in a form the body absorbs and uses effectively.
We invest in clinical trials because it's the only way to show that AG1 truly works. In the supplement industry, this level of research is rare – for us, it's the standard.
AG1 has been studied in four gold-standard clinical trials: randomised, placebo-controlled, and double-blinded.ᵃ⁻ᵈ
We set the bar for quality – and keep raising it. From research and formulation to sourcing, manufacturing, and testing, every scoop of AG1 is backed by rigorous protocols to ensure it’s safe, effective, and consistently high quality.
