The global dietary supplements market was valued at over $150 billion in 2024, reflecting a growing consumer interest in optimizing nutrition. Greens powders, in particular, have emerged as a popular category, but not all are created equal. When comparing Athletic Greens' AG1 and Field of Greens by BrickHouse Nutrition, the core distinctions lie in their formulation philosophy, ingredient transparency, and target audience. One is a comprehensive, all-in-one daily health drink, while the other positions itself as a straight-forward, whole-food vegetable and fruit powder.
The Core Difference: All-in-One vs. Whole Food Focus
AG1 and Field of Greens differ significantly in their primary approach. AG1 is formulated as a comprehensive nutritional supplement with a wide range of ingredients, aiming to replace multiple daily supplements. Field of Greens, on the other hand, emphasizes providing nutrients from organic, whole fruits and vegetables.
AG1: The Comprehensive Blend
AG1 contains over 75 ingredients, including vitamins, minerals, probiotics, prebiotics, digestive enzymes, adaptogens, and mushrooms. It is designed to support energy, gut health, immune function, stress recovery, and cognitive health. AG1 uses proprietary blends, meaning the exact quantity of each ingredient isn't fully disclosed. It is NSF Certified for Sport.
Field of Greens: The Organic Produce Supplement
Field of Greens focuses on organic, freeze-dried fruits and vegetables to supplement dietary intake. It aims to provide nutrients from real food to help fill nutritional gaps. Field of Greens uses a Nutrition Facts panel for greater transparency, though some blends may still be proprietary. They also offer variations targeting specific needs like energy or cognitive function.
Ingredient Philosophy and Transparency
AG1 and Field of Greens also differ in their ingredient sourcing and labeling. AG1 prioritizes ingredient potency and bioavailability, with extensive testing for contaminants, but it is not certified organic. Field of Greens' main feature is its USDA organic certification, ensuring its fruit and vegetable ingredients are organic. AG1's use of proprietary blends can make it difficult to know the exact dosage of certain ingredients. Field of Greens aims for clearer labeling with its food-based panel.
