AG1 is trusted by experts in health and nutrition
Dr. Victoria Nicholas
Gastroenterologist
“AG1 is particularly well suited to people with busy lifestyles, or anyone looking for a simple way to complement a balanced diet and build a consistent, positive habit at the start of the day.”
Georg Abel, PhD
Nutritional scientist & sports nutritionist
“I see AG1 as a practical and meaningful addition to support daily nutrient intake, especially in real-life situations where nutrition is not always perfectly optimised.”
Jamie Wright, MSc
Nutritionist
“AG1 is one of the few supplements I would feel entirely comfortable in recommending with real confidence, largely because it's one of the few products in the category that has invested in third party testing, counterfeit protection procedures and proper clinical evidence for its finished formula.”
Charlie Watson, MSc
Registered Dietitian & Sports Nutritionist
“Supplements are such a minefield and unregulated market with wildly varying quality and quantity – 3rd party testing and Informed Sport means it is what it says it is. It's safe, it's reliable and it's verified. I wouldn't use or recommend anything that wasn't.”
Adriano Dos Santos, MSc
Nutritionist & Circadian Researcher
“What AG1 brings to the table, from my perspective, is convenience, formulation coherence, and critically a level of clinical investment that is unusual in this category: third-party testing, Informed Sport and Cologne List approval, and four RCTs on the formula rather than on isolated ingredients."
